Fungal Biodegradation of Lignin-Like Pollutants

Environmental Assessment for Three Commonly Used Pesticides: Alachlor, Lindane and Parathion

Evaluation of Vegetative Filter Strips as a Management Practice for Non-point Source Pollution

Movement of Triazine Herbicides and Metolachlor in a Sandy Soil
The movement of atrazine, cyanazine, simazine, and metolachlor was studied in an Evesboro loamy sand soil. Both no-tillage and conventional tillage treatments were used. Atrazine, simazine,...

Groundwater Loadings of Pesticides From Chemigation: A Gleams Model Simulation
This paper describes how, with slight modifications, the GLEAMS model (Groundwater Loading Effects of Agricultural Management Systems) was used to represent chemigation for herbicides,...

The Influence of Water Tables on Herbicide Losses
Atrazine and metolachlor were applied preemergent on April 22, 1987, to silage corn on high watertable fields which were either subsurface drained (104 mm drain tubes 1 m deep) or surface...

Agriculture and Groundwater Quality
Nitrates and pesticides used in agriculture cause groundwater degradation. Agricultural practices in the U.S. will have to be changed to alleviate the health effects of these chemicals....

Sport Fish Consumption Advisories in the Great Lakes Basin: Assessment of Policy to Protect Human Health
Fish consumption advisories for Great Lakes sport fish are based on U.S. Food and Drug Administration (FDA) or U.S. Environmental Protection Agency (EPA) tolerance or action levels for...

Future Shock for Farmers
An expert panel of water and agricultural practices specialists met and predicted how the nation should and might deal with problems associated with nonpoint pollution sources, especially...

Modeling Pesticide Metabolite Transport with Gleams
The GLEAMS model (Groundwater Loading Effects of Agricultural Management Systems) was modified to simulate the generation and degradation of pesticide metabolites. Translocation of the...

Adsorption, Desorption and Transport of Pesticides in Groundwater: A Critical Review
Adsorption and desorption are major mechanisms affecting the transport and fate of pesticides in groundwater. Equilibrium, chemical nonequilibrium and physical nonequilibrium adsorption...
