Target Audience: The target audience is usually the agency that submitted the samples. In the cases of suspected poisonings, the audience is the appropriate agencies and individuals submitting the samples. For the work on the lobster samples, it is the Connecticut Department of Energy and Environmental Protection (DEEP) and the Connecticut Legislature. Changes/Problems: In 2014, three new instruments were acquired: 1) An Agilent 7890A Gas Chromatograph (GC) with a 5975C inert XL mass selective detector (MSD), 2) An Agilent 7890B GC with a 5977A MSD and 3) a Thermo Q-Exactive ultra high pressure liquid chromatographic mass spectrometer. The analytical methodologies in use in our laboratory are continually modified and updated as considered appropriate by our analysts. Our laboratory is currently working its way through the process of attaining ISO/IEC 17025:2005 accreditation. What opportunities for training and professional development has the project provided? Due to work performed on the analysis of pyrethroid insecticides in lobsters in 2013, both Dr. Jason C. White and Dr. Walter J. Krol were appointed to the Long Island Sound lobster pesticide steering committee and participated in the first meeting at the Marine Fisheries Division of the Connecticut Department of Energy and Environmental Protection (DEEP), 333 Ferry Rd, Old Lyme, CT 06371 on July 11, 2014 How have the results been disseminated to communities of interest? The 2013 pyrethroid in lobster work was submitted to the DEEP upon completion, and presented to the Connecticut legislature in 2014. In other cases, final reports were issued to the appropriate parties submitting the samples. What do you plan to do during the next reporting period to accomplish the goals?

What was accomplished under these goals?
We note that although this is a termination report,this is a long running state project that will continue on in a new project with identical goals and objectives. The accomplishments that follow focus on the last year, although the report is highly indicative of past years activities. For specifics on previous years, we refer the reader to past annual reports. Occasionally samples are submitted by local health departments, veterinarians, farmers, and municipal agencies, the Connecticut (CT) Department of Consumer Protection (DCP) and Department of Energy and Environmental Protection (DEEP), requesting assistance in identifying potential poisoning of domesticated or wild animals. During the current timeframe, investigative work was performed on five samples for 1 particular incident. A local veterinarian had a client whose two dogs developed sudden liver and kidney failure at about the same time. One pet passed away and the postmortem exam was performed at UConn Diagnostic Lab. The diagnosis from the lab was toxicosis causing liver failure. The suspects were blue/green algae, Amanita mushrooms and/or cycad plants. The owners were desperate to find out what affected both dogs. The owners had noticed mushrooms in their yard, and also had a pool with a torn liner in which there was water containing algae. Samples of water, pool liner, plant and fungal material were delivered to the Department of Analytical Chemistry (DAC) at the Connecticut Agricultural Experiment Station (CAES). Microscope slides were prepared from the water samples and cells removed from the pool liner. Examination of these slides indicated that no harmful blue/green algae were present. No positive identification could be made on the plant or fungal material samples owing to their states of decomposition.

Target Audience: The target audience istypically the agency that submitted the samples. For the work on the lobster samples described in this report, the submitting agency is the Connecticut Department of Energy and Environmental Protection (DEEP). It also includes the laboratory performing the original work, The Center for Environmental Sciences and Engineering at the University of Connecticut (UCONN), the Connecticut Legislature, the citizens of Connecticut, the lobstermen of Connecticut, and the pesticide industry as a whole. In the cases of the suspected poisonings, the target audience is the local agencies or departments submitting the samples. Changes/Problems: In 2013, two new instruments were acquired: 1) a Thermo triple quadrapole gas chromatographic mass spectrometer and 2) a Thermo Velos ultra high pressure liquid chromatographic mass spectrometer. The analytical methodologies in use in our laboratory are continually modified and updated as considered appropriate by our analysts. New methods are developed by analysts as appropriate. What opportunities for training and professional development has the project provided? The lobster work provided an opportunity to meet with members of The University of Connecticut and the Connecticut Department of Energy and Environmental Protection in Old Lyme, CT at the Marine Fisheries Division of Connecticut Department of Energy and Environmental Protection, 333 Ferry Rd, Old Lyme, CT 06371. How have the results been disseminated to communities of interest? The Connecticut Department of Energy and Environmental Protection will report this information directly to the Connecticut Legislature in Hartford. At this stage, all interested parties will be made aware of the findings. In the case of the alleged animal food incidents, final reports were issued to the appropriate health departments submitting the samples. What do you plan to do during the next reporting period to accomplish the goals? The samples tested in this work originate outside the control of the Connecticut Agricultural Experiment Station (CAES). Samples will be tested by the CAES as they are submitted.
Impacts
What was accomplished under these goals?
Occasionally samples are submitted by local health departments, farmers, municipal agencies, the Connecticut (CT) Departments of Consumer (DCP) and Energy and Environmental Protection (DEEP), and the University of Connecticut requesting assistance in identifying potential poisoning of domesticated or wild animals. During the current timeframe, investigative work was performed for three separate incidents. The first of these involved an individual whose dog had recently died. Sometime after getting a new dog, the individual found two meat laden bones in her back yard. The individual thought that someone may have been trying to poison the dogs. Two (2) samples of meat were submitted by the Town of Berlin Animal Control Officetested for pesticides, including insecticides and rodenticides. None were found. In a second incident, an individual thought that someone was trying topoison her cat. A Ziploc bag of brown, free flowing material (1 sample) was delivered by the Town of Wallingford Health Department for testing. The material was free flowing, and had the consistency of sand. For all practical purposes it was identified as sand. Chemical analysis revealed the presence of 11 ppm chlordane. No other pesticides, including insecticides and rodenticides, were found. The third case involved testing lobster meat and hepatopancreas for the pyrethroids bifenthrin, lambda-cyhalothrin, permethrin, and resmethrin and for the juvenile hormone analog / growth regulator / insecticide methoprene. In 2011 traces of methoprene and resmethrin were found in lobsters obtained from Long Island Sound by the University of Connecticut (UCONN). These chemicals were being used to control mosquitoes which carry the west Nile virus in Fairfield County. The UConn study was expanded in 2012 to nearly 100 lobsters with funding provided by the Connecticut Legislature. Methoprene and additional pyrethroids were found in a substantial number of samples. As confirmation of these findings, the Connecticut Department of Energy and Environmental Protection (DEEP), who was responsible for this study, asked the Connecticut Agricultural Experiment Station (CAES) to retest and confirm some of the results obtained by UCONN. A modified Quick, Easy, Cheap, Efficient, Rugged and Safe (QuEChERS) was developed and implemented for the extraction of these samples. Analysis was performed using a newly acquired triple quadrapole mass spectrometer. None of the 14 tissue samples tested was found to contain any of the 5 chemicals in question. This was confirmed by standard addition of the pesticides to the samples. The CAES findings were contradictory to those of UCONN and additionalinvestigations with both laboratoriesare now being planned.

OUTPUTS: Occasionally, samples are submitted by local health departments, farmers, municipal agencies, the Connecticut (CT) Departments of Consumer (DCP) and Energy and Environmental Protection (DEEP), and the University of Connecticut requesting assistance in identifying potential poisoning of domesticated or wild animals. In 2012, there was even a request from the Minnesota Department of Agriculture for the analysis of pesticide residues in honey bees. There were a total of seventeen samples submitted during the current reporting cycle. Seven of these samples were submitted by the Minnesota Department of Agriculture, and the remaining ten were obtained by the Entomology Department at the Connecticut Agricultural Experiment Station on behalf of an apiarist in Connecticut who had suffered a colony die off. All these samples were tested for pesticide residues to determine if that might have been the cause of death. Following analysis, the seven samples from Minnesota were all found to be pesticide free. There were three chemicals found on the bees collected in Connecticut. The acaricide fipronil was found on four of the bee samples at an average concentration of 0.026 ppm (0.016 - 0.045 ppm). The insecticide methomyl was found on four different bee samples at an average concentration of 0.068 ppm (0.016 - 0.086 ppm). The latter four samples were also found to contain residues of the insect repellant DEET at an average concentration of 0.023 ppm (0.015 - 0.038 ppm). Unfortunately the last two samples from the colony were delivered in a large volume of ethanol. No pesticide residues were found in these samples. It is currently unknown if these bees died from over exposure to pesticide residues or from other causes. PARTICIPANTS: Analysts: Walter Krol, Brian Eitzer, Terri Arsenault. Supervisor: Jason C. White. TARGET AUDIENCES: Agencies of the State of Connecticut, municipal agencies the citizens of Connecticut as well as other State agencies. PROJECT MODIFICATIONS: The analytical methodologies in use in our laboratory are continually modified and updated as considered appropriate by our analysts.
Impacts
The analysis provided by the Department of Analytical chemistry assists State of Connecticut and other State Agencies as well as local agencies lacking the analytical tools required to detect intentional and unintentional poisoning. This work nurtures and develops cooperative interactions with other State of Connecticut agencies and other State agencies and also directly relates to our capabilities in the arena of counterterrorism.

OUTPUTS: Occasionally samples are submitted by local health departments, farmers, municipal agencies, the Connecticut (CT) Departments of Consumer (DCP) and Energy and Environmental Protection (DEEP), and the University of Connecticut requesting assistance in identifying potential poisoning of domesticated or wild animals. There were a total of 11 samples submitted during this reporting period. One sample, comprised of four subsamples, was from The Connecticut Agricultural Experiment Station. It was related to potential insecticide poisoning of domesticated bees. The subsamples, which were comprised of assorted hive material, were found to contain the insecticide fluvalinate (0.073 0.281 ppm), a chemical used in hives to control varroa mites. The remaining ten samples originated from the CT Department of Energy and Environmental Protection and were related to three separate incidents. In the first incident, an application of pesticides was made to an area where several animals had died. One sample of the tank mix used for the application was collected and analyzed. The mix was found to contain seven different pesticides at relatively low concentrations (0.010 - 0.260 ppm). Since no animal tissue was received with this sample, it was impossible to determine if the cause of death might be related. In a second incident, a CT resident reported that a dog had died and was trying to link it to plants which were dying on her property. Three samples of soil and brush were collected from the property and tested for pesticide residues. No pesticide residues were found. The third, and final, incident concerned an illegal application of pesticides inside a home. This application had the potential of injuring pets and small children. The resident had a problem with rodents and hired an applicator to apply bait. The applicator left behind two bait boxes and two open containers containing a fat and pesticide cocktail. All the samples were all found to contain a tracking powder containing the rodenticide diphacinone (0.2% / wt.) which was spread from the traps and containers throughout the house by the activity of rodents. This was determined by wipe samples obtained from throughout the residence. The open containers were found to contain mixture of several insecticides (0.002 - 64 ug/gm) which were mixed into the fat used as bait. The bait boxes themselves were found to contain the rodenticides warfarin and bromadiolone (0.020 - 53 ug/gm) as well as several other insecticides (0.014 - 310 ug/gm). Fortuitously, neither the pets nor the children in question suffered any injury as a result of this misapplication. PARTICIPANTS: Analysts: Walter Krol, Brian Eitzer, Terri Arsenault.

Outputs
OUTPUTS: Occasionally, samples are submitted by farmers, staff members in local health departments, municipal agencies, the Connecticut (CT) Departments of Consumer (DCP) and Environmental Protection (DEP), and the University of Connecticut requesting assistance in identifying potential poisoning of domesticated or wild animals. There were a total of 14 samples submitted during this reporting period. Nine of these were related to potential insecticide poisoning of domesticated honey bees; two from the CT DEP; seven from the CT Agricultural Experiment Station. No pesticide residues were found in any of the nine bee samples submitted for analysis. Five of these samples were from a necropsied squirrel from New Haven. Local citizens had noticed an unusually high number of dead squirrels in their neighborhood and contacted the local health department. There was suspected poisoning. A representative of the New Haven Health department collected a squirrel, necropsied it, and provided samples of skin, bone, liver, lung, and fat for analysis. There were no stomach contents present during the necropsy. Low levels of the fungicide chlorothalonil were found in all the tissues, 0.25 - 0.95 ppm, and two Persistent Organic Pollutants (POP's), chlordane and DDE, were found in the liver and lung. It is unlikely that these pesticides were present at sufficient levels to cause the death of this animal. These results were immediately forwarded to the appropriate officials. There were no further reports of squirrels dying of unknown causes following this investigation. PARTICIPANTS: Analysts: Walter Krol, Brian Eitzer, Terri Arsenault. Supervisor: Jason C. White.

OUTPUTS: Occasionally, samples are submitted by local health departments, farmers, municipal agencies, the Connecticut Departments of Consumer and Environmental Protection, and the University of Connecticut requesting assistance in identifying potential poisoning of domesticated or wild animals. There were a total of 17 samples submitted during 2009. Two of these were related to potential insecticide poisoning of domesticated bees. In the first of these, no pesticide residues were found. The second sample, however, was found to contain residues of two pesticides, both far below their respective LD50 values. Eight of the total samples were involved in a potential dog poisoning in which there was no proof that the animal suffered any injury. The remaining seven samples were related to a dog that died within a short time of ingesting part of a dead coyote encountered on a routine walk with its owner. The inspector delivered a towel from the owner that was near the dying dog, the jacket of the owner worn during the process, and a leg bone from the coyote. Following necropsy, tissue samples of the dog were delivered for analysis. All the samples tested positive for the methyl carbamate insecticide carbofuran with the highest levels being found in the stomach tissue of the dog. It appears that the dog died of secondary poisoning from an illegal use of carbofuran. PARTICIPANTS: Analysts: Brian Eitzer, Terri Arsenault Supervisors: MaryJane Incorvia Mattina, Jason C. White. TARGET AUDIENCES: Agencies of the State of Connecticut, municipal agencies and the citizens of Connecticut. PROJECT MODIFICATIONS: Dr. Mary Jane Incorvia Mattina retired as supervisor of the Department of Analytical Chemistry in July of this year. Dr. Jason C. White has been named Chief Scientist and Department Head.

Progress 01/01/08 to 12/31/08
Outputs
OUTPUTS: During the period of this project, there were three distinct groups of samples related to possible animal poisonings. The first was a group of 6 turtle blood samples taken from turtles residing in New Haven harbor. This project was undertaken on behalf of students attending a public magnet high school. Each sample was screened for 23 potentially toxic elements. In all cases, the results were below federal tolerance levels. The second group were 5 samples of pet food which were screened for melamine and analogues. These samples were selected from the group submitted to our laboratory annually by the Department of Agriculture, which were notable for containing well above the label guarantee for protein. No melamine or its analogues was found although the data for one sample did stimulate discussion between our laboratory and staff from the Department of Agriculture. Finally, 8 frozen fish samples were submitted by the Connecticut Department of Environmental Protection with the request that they be screened for agrochemicals. These samples are in progress with no data to date of concern. PARTICIPANTS: Analysts: Craig Musante, Terri Arsenault, William Berger Supervisor: MaryJane Incorvia Mattina TARGET AUDIENCES: Agencies of State of Connecticut as well as Connecticut students and citizens. PROJECT MODIFICATIONS: Not relevant to this project.
Impacts
Our interactions with students from local schools and colleges have included not only the conduct of the analyses, but also inclusion of the students in the hands-on laboratory work. We provide data that would not be accessible for these students through any other avenues. Our melamine expertise is applied to monitor the marketplace more broadly than our commitment to FDA alone. This work will develop even more broadly through cooperative interactions with other State of Connecticut agencies. Finally, the analysis of fish and tissues from other wildlife can contribute significantly to monitoring the environment within Connecticut.

OUTPUTS: Municipal health departments and police departments, the Connecticut Department of Agriculture, local land trusts, and growers request assistance in identifying possible poisoning of domestic and wild animals. We conducted several such analyses originating from these sources within the reporting period specified. Related to the adulteration of feedstock imported from China, used in the manufacture of pet food, we worked with the US FDA to analyze 26 products and found one which did contain melamine and analogues. We also analyzed four such state samples, none of which were contaminated. We analyzed two samples of bees for possible lethal levels of agrochemicals. Finally, a city police department requested our assistance in the analysis of several samples related to a case of dog poisoning. Within an hour of sample submission we were able to confirm to the submitting officer that the sample in question did contain a rodenticide.
PARTICIPANTS: MaryJane Incorvia Mattina, Walter Krol, Brian Eitzer, Craig Musante
TARGET AUDIENCES: Our traditional stakeholders such as state agencies, growers, the agricultural community in general are becoming aware of our enhanced analytical capabilities. In addition, some non-traditional stakeholders such as local and state police departments are now also aware of our instrumental arsenal through their interaction with our traditional partners. This enlarged audience for our work is appropriate.
Impacts
Our assistance to state and municipal agencies that do not have the in-house capability for analyzing samples related to domestic and wild animals provides them with a means of detecting intentional and unintentional poisoning. Once again the impact of this assistance has increased considerably in the light of homeland security. Since we installed and are operating several additional pieces of analytical instrumentation, which will increase the number of analytes we will be able to identify, the impact of our laboratory for these types of analyses will increase in the near future. This also directly relates to our capabilities in the arena of counterterrorism.

Occassional samples are submitted to our department by municipal health departments requesting assistance in identifying possible poisoning of wild or domestic animals. During the period covered by this report four avian tissue samples were submitted which originated from four dead swans found on a Connecticut lake. Measurable amounts of lead were detected in three of the four samples. A different sample, consisting of two meatballs, was submitted by a municipal health department as part of an investigation into possible pet poisoning. We determined that the meatballs contained pellets of zinc phosphide from a commercially available rodenticide product.

Progress 01/01/00 to 12/31/00
Outputs
Several different projects required the analysis of animal tissue samples. For example 163 avian tissues were analyzed for the presence of pesticides to determine the possibility of both acute and chronic pesticide poisoning. The birds were originally collected to detect the presence of West Nile virus; a substantial number of tissue samples contained older organochlorine pesticides no longer in use in the U.S. Twenty samples from deer were examined for residues of Amitraz. This project is part of an investigation to determine the efficiacy of the pesticide for control of tics bearing Lyme disease. Two fish samples from a Connecticut lake were examined to determine the fate of weed control pesticides applied to the lake.

Outputs
From 1 January 1993 to 31 December 1993 we analyzed a total of 437 samples for pesticide residues and 38 samples for pesticide formulations. Residue samples consisted of produce sampled by the Connecticut Department of Consumer Protection in the annual marketbasket survey, which are analyzed by the Department of Analytical Chemistry in a cooperative effort.. We employ a multiresidue method developed in-house to quantitate fifty pesticides using gas chromatography with a variety of detectors, such as electron capture, flame photometric, and electrolytic conductivity. We are also making extensive use of mass spectrometry for confirmation and in some cases original identification of the pesticide. Of the total residue samples 21 were violative samples, either containing overtolerances of pesticides, or residues not permitted on the crop sampled. During 1 January 1993 to 31 December 1993 we analyzed 38 pesticide formulation samples in conjunction with the Department of
Environmental Protection. Of this number four samples were over- or under-formulated and 3 products had not been registered in the state.

From 1 January 1992 to 31 December 1992 we analyzed 74 animal tissue samples fordetermination of suspected poisoning. Of this number, approximately 10 samples were avian tissue submitted for determination of heavy metal and pesticide contamination. These included 3 specimens of Canada geese found dead or dying in close proximity to a public drinking water supply. We determined zinc poisoning due to the ingestion of a registered rodenticide, zinc phosphide, as the cause of death. We also carried out the analysis of tissues from 59 hunter-killed deer in the state of Connecticut to determine possible contamination with cadmium. The results of this work was the issuance of a public health advisory from the Connecticut Department of Environmental Protection concerning the consumption of deer meat.
