National Characterization of Pesticide Runoff and Erosion Potential to Put USEPA Standard Ecological Scenarios In Context for PyrethroidsJuly 18, 2022 | By: Amy RitterDownload NowDecision-making for pesticide registration by the US Environmental Protection Agency (USEPA) …
Population models can provide useful tools to assess potential exposure to, and effects from, pesticides – as well as evaluate mitigation options – on listed species by bridging the gap between laboratory endpoints derived from surrogate species and populations in the context of their habitat. We applied a hybrid model of the Topeka shiner (Notropis topeka), a small endangered cyprinid fish endemic to the US Midwest, to assess potential population‐level effects of realistic exposures to a common fungicide (benzovindiflupyr).
Coral decline has been observed worldwide including to reefs in Florida. Several global and local stressors have been implicated as contributors to the decline of coral populations The most pervasive and deleterious stressor is the global event of rising atmospheric CO2 levels which results in sea temperature changes and acidification. These global warming changes cause coral bleaching and ultimately coral death. Stony Coral Tissue Loss Diseases (SCTLD) is causing widespread devastation in the Florida Reef Tract. Expert coral biologists have identified the most important stressors to reefs in Florida – invasive species, unsustainable fishing practices, coastal development, untreated or poorly treated wastewater, urban and agricultural run-off, and tourism-related damage.
The risk assessment tool WISPE (The World Integrated System for Pesticide Exposure) was developed which includes the environmental fate and transport models winPRZM and EXAMS. WISPE is a computer modelling tool developed to evaluate the potential impact of crop protection products on the environment in Norway. WISPE makes it possible to estimate pesticide exposure in surface- and groundwater resources considering Norwegian conditions for 11 different crops.
