Accomplishments
Intended Outcomes and Potential Impacts of Specific Objectives and Projects
Obj. 1: Identify, develop, and/or validate trace residue analytical methods, immunological procedures, and biomarkers: Scientists Hawaii station developed an immunoassay for the insecticide imidacloprid. Antibody kinetics studies revealed that the antibody is specific to imidacloprid. The assay had a half-maximal inhibition concentration and the limit of detection of 0.8 and 0.1 µg/L, respectively. This is an economical, fast and sensitive assay to measure imidacloprid in environmental and biological samples.
Obj. 2: Characterize abiotic and biotic reaction mechanisms, transformation rates, and fate in agricultural and natural ecosystems: Pesticide runoff to urban streams and estuaries is known to cause aquatic toxicity. Consequently, the US EPA has adopted TMDLs for diazinon, chlorpyrifos, and the chlorinated insecticides. Synthetic pyrethroids being replacements for diazinon and chlorpyrifos are even more toxic to aquatic organisms than the OP compounds. Scientists at UC-Riverside found that the strong adsorption of synthetic pyrethroids to suspended particles in runoff water greatly decreases the actual toxicity of pyrethroids to indicator species such as Ceriodaphnia dubia, and practices of suspended solid removal are highly effective in eliminating pyrethroids from the runoff. The close interactions with stakeholders such as growers and regulators facilitated information and technology transfer. The mitigation practices were implemented by growers and used in outreach seminars. The research findings were also conveyed to Regional Water Quality Control Boards and California Department of Pesticide Regulations.
1,3-Dichloropropene (1,3-D) is one of the four registered soil fumigants. Use of methyl bromide will be suspended in January 2005. 1,3-D is considered to be a potential replacement for methyl bromide. The scientists at Florida station found that 1,3-D rapidly volatilized from the surface of the bare bed and the polyethylene mulch (PE) covered bed while concurrently concentration of 1,3-D in the root zone in the beds rapidly declined. Virtually impermeable film (VIF) was a better barrier for retarding volatilization from bed surface and retaining greater concentration of 1,3-D in the root zone. VIF may be useful for in field beds.
The producers of the fungicide benomyl have recently experienced legal battles as farmers claim that the fungicide damaged crops as by the proposed cause being N,N‘‘-dibutylurea (DBU), a breakdown product of benomyl during its storage. W45 members at Indiana station found that DBU degradation was primarily microbial and degradation was relatively fast with less than 10% remaining after 6 weeks except when at least two of the following conditions existed: high clay content (> 40%), dry conditions, high pH, or high temperature. If DBU is found in soils, it is most likely from application of DBU-containing benomyl formulations and not from DBU production in soils. Also DBU inadvertently applied to soils through benomyl formulations is unlikely to persist.
Researchers in Nevada demonstrated that polycyclic aromatic hydrocarbons (PAHs) degraded rapidly in freshwater lakes.. Photolysis rates for PAHs varied, but for those compounds that exhibit phototoxicity, the half-lives are generally less than one day of sunlight. The ecological impact of PAH from marine engines is equivocal, since these compounds were found only at very low concentrations in the two fresh water lakes examined, and, particularly for Lake Tahoe.
Researchers at Cornell University conducted research to integrate an anodic Fenton treatment (AFT) and a mixed microbial culture to degrade the herbicide metribuzin. Complete and rapid removal of metribuzin by AFT was demonstrated. The appearance and subsequent degradation of two metribuzin degradation products were observed. It was found that microbial degradation occurred in the AFT effluents as compared to the original metribuzin solution without AFT treatment. This research supports the continued investigation of AFT and biodegradation as a binary treatment of aqueous pesticide wastes.
Scientists at Oregon station studied using the GC retention method to estimate vapor pressures for five pesticides (triclopyr, ethofumesate, triadimefon, chlorpyrifos, and propiconazole) over a range of environmentally relevant temperatures. The results affirm previously reported sources of error for semi-polar and polar compounds ? specifically, vapor pressure estimates assume that relative retention times for the test compounds are determined by vapor pressure only, while differences in activity coefficients between test and reference compounds may also influence relative retention times. In addition, when the measured vapor pressure/temperature relationship for the reference compounds is within the temperature range of interest for the test compounds, temperature extrapolation error is minimized.
Researchers in Washington studied pheromone mating disruption as an important integrated pest management tool for controlling codling moth injury in apple and pear orchards in the Pacific Northwest. In 2003, a laboratory chamber volatile trapping system was developed to examine pheromone released in the gas-phase from field-aged commercial dispensers, which was compared with direct analysis of field-aged commercial dispensers. The two approaches provided similar release information of commercial dispenser performance throughout the codling moth mating season. In 2002-2003, air sampling and trace-level analytical techniques were developed and will be tested in the orchard in the summer of 2003 for evaluating season-long dispenser release behavior. The new integrated method should in the future better aid in the understanding of pheromone disruption devices under canopy conditions.
Objective-3: Determine adverse impacts from agrochemical exposure to cells, organisms, and ecosystems. Scientists at UC-Davis continued to work on validation of using cholinesterase assay to monitor exposures to organophosphate insecticides in blood from pesticide handlers in the agricultural workplace in California. The same red blood cell ghost standard and human blood samples were used among all the participating laboratories including clinical laboratories. Results of cholinesterase activities for whole blood, red blood cell and serum enzymes were compared. Many laboratories achieved a better than 0.90 correlation with the UCD W45 laboratory.
Researchers in Hawaii examined the physiological activity of the insecticide imidacloprid was in frog embryonic muscle cells as a model system to study mechanism of nicotinoid teratogenicity. Acetylcholine as a natural modulator of muscle contractions and nicotine as an established pharmacological probe were tested alone or together with imidacloprid for their ability to induce contractions in frog embryonic muscle cells. Acetylcholine was more effective in causing muscle contractions than nicotine. Imidacloprid attenuated acetylcholine and nicotine effects but itself did not cause muscle cell contractions.
Researchers in Nevada used homing pigeons to model the biological impact of exposure to sub-lethal exposures to various agrochemical and environmental contaminants. Exposure of the homing pigeons to cyanide in the drinking water resulted in: a decrease in tissue ATP levels similar to that seen in the mallard duck and a dose-dependent increase in flight time for the birds, suggesting a dose-dependent biological impact. This group recently constructed a new facility that allows housing, breeding and training homing pigeons for the studies. They currently have 60 birds between 0 and 4 months old, and have begun training these birds to home back to the roost so that the studies can start later this summer.
African rue has become established in several western states, where it poses a threat. Scientists in New Mexico investigated plant-herbicide-water stress interactions. The results showed that although less active physiologically, plants under water-stressed conditions were more sensitive to herbicide application, with metsulfuron and imazapyr causing the most damage. One day after treatment (DAT), non-watered plants were the only treatments with visible injury as measured by wilting. By 21 DAT, herbicide activity continued to be greater in the non-watered compared to the watered treatments. This initial screening suggests that water status plays a role in altering African rue?s sensitivity to herbicides.
Scientists in USDA-ARS in Beltsville initiated a project in the Fall 2001 to assess the impact of intense agricultural production on air and water resources of the South Florida sensitive coastal ecosystems, which have had die-off of sea grass beds, declines in sponge and shellfish populations and development of noxious algal blooms in the past decade. Rain and air samples were collected from a site in Homestead, Florida, and a newly added site at Adams Key in Biscayne National Park. Surface water samples were collected during the growing season from the six sites along the Mowery Canal and surrounding agricultural area canals which empty into Biscayne Bay, and in the Biscayne Bay. Preliminary data suggest that agriculture and urban activities may impact surrounding ecosystems.
Obj. 4: Develop technologies that mitigate adverse human and environmental impacts. Researchers at USDA-ARS in Riverside investigated the volatilization and distribution of the fumigants 1,3-D, MITC, propargyl bromide (an unregistered fumigant), and chloropicrin. Mesocosm experiments indicated that increasing the depth of application or use of a surface tarp decreased maximum and cumulative flux, resulted in higher fumigant concentrations throughout the soil compared to untarped soil, and reduced the rate of fumigant dissipation from soil. Tarping the bed with standard 1-mil HDPE and virtually impermeable plastic reduced cumulative emissions by 5-60% and 68-99%, respectively, relative to emissions from bare soil.
Scientists in Utah PCP biodegradation by Phanerochaete chrysosporium, Pycnoporus cinnabarinus and Trametes versicolor as model white- soft- and brown-rot fungi, respectively. All the fungi were shown to secrete oxidative enzymes, but T. versicolor showed little or no ability to mineralize PCP and P. cinnabarinus had only limited ability to mineralize PCP. The disappearance of PCP was noted with all three species. Only P. chrysosporium exhibited the ability to methylate PCP. The other species polymerized PCP to a product having spectral similarities to oxidized guaiacol.
Work Plan for Next Year
W-45 members will continue to work on the on-going projects described in this report and new collaborative thrusts described under the objectives of the W-45 project. All the members continue to put efforts on collaboration which includes cooperative grants being written, cooperative research projects being initiated, and sharing of research approaches and analytical techniques among institutions. A good example of collaboration is collaborative participation of Gan, Aust, Hapeman, Papiernik, Lemley etc. in 2002 fall ACS Division of Environmental Chemistry Symposium. Gan, Zhu, Aust and Lemley co-edited a book entitled ?Pesticide Decontamination and Detoxification? for the proceedings articles. American Chemical Society Series 863, ACS, Washington, DC, 2003.

Impacts
- Riverside: Improving Adsorption Measurement for Synthetic Pyrethroids: We developed a selective approach that improves the determination of adsorption coefficient for synthetic pyrethroids and likely for other adsorbing pesticides. This method may be used for better predicting the fate and ecotoxicological effects of other pesticides such as DDT.
- Florida: We know very little about the distribution of the fumigants in the root zone and their volatilization loss after application to shallow subsurface of Florida sandy soil. This report represents our first stage of research aimed to understand the behavior of the three registered fumigants, 1,3-D, chloropicrin and metam sodium in Florida sandy soil and to enhance their pesticidal efficacy. We think VIF will be useful for increasing 1,3-D efficacy and reducing 1,3-D volatilization loss.
- Hawaii: Imidacloprid is an effective insecticide but concern of wind drift, leaching into surface water and ground water, and toxicity to honey bees. A new monoclonal antibody was derived and used to develop a new immunoassay for imidacloprid. The new assay can be a good tool for monitoring of imidacloprid in environmental and biological samples. Examination of kinetics of the monoclonal antibody provides information for future antibody production.
- Indiana: Desoxycarbadox is the only metabolite found in manure from carbadox-fed swine. Tylosin A and the primary metabolites tylsoin aldol and mycaminosyltylonolide (OMT) are present in manure from Tylan-fed swine. Our research suggests that any future reconnaissance of residual manure-applied antibiotics and associated metabolites should focus on the role of surface runoff, erosion, preferential flow, and facilitated transport to ecosystem loadings.
- NM: African rue has become established in several western states where it poses a threat of further spread. We found that although less active physiologically, plants under water-stressed conditions were more sensitive to herbicide applications than those receiving water, with metsulfuron and imazapyr causing the most damage. This suggests that water status plays a role in altering Afican rue's sensitivity to herbicides and therefore, may influence successful management of this invasive weed.
- Nevada: The impact of non-lethal acute agrochemical exposures on non-target avian species is very difficult to access. The use of homing pigeons to mimic the behavior of migratory birds may provide us with such a model. The goal of this project is to establish this model such that testing of various agrochemicals using this model will help determine the safety of these agrochemicals
- Impact 7 New York (Cornell University) Agricultural Experiment Station: This years work demonstrates that the chemical treatment method being used to pretreat pesticide wastewater makes the wastewater more suitable for normal wastewater sewage treatment, a biological process. The biological process alone cannot break down many types of pesticides. The combination of the two processes, chemical and biological, is a practical approach to this environmental problem
- Impact 8 USDA ARS Riverside Experiments were conducted to monitor the volatilization and distribution of the fumigant compounds. Because the great U.S. economic loss resulting from the transition from the fumigant methyl bromide to alternative fumigant compounds, and because the use of the alternative fumigants 1,3-D and MITC is being increasingly restricted based on air quality concerns, this research is critical for maintaining soil fumigation as a viable option in American agriculture
- Impact 9 The work of the W-45 project serves to provide information critically important for establishment of the safety of current pesticide uses as well as recommendation of best management practices.
