Pesticides in Mississippi air and rain: A comparison between 1995 and 2007

by John Wiley & Sons, Ltd.  (Feb. 19, 2014)

A variety of current‐use pesticides were determined in weekly‐composite air and rain samples collected during the 1995 and 2007 growing seasons in the Mississippi Delta agricultural region. Similar sampling and analytical methods allowed for direct comparison of results. Decreased overall pesticide use in 2007 relative to 1995 generally ...

Selecting surrogate endpoints for estimating pesticide effects on avian reproductive success

by John Wiley & Sons, Ltd.  (Aug. 3, 2013)

A Markov chain nest productivity model (MCnest) has been developed for projecting the effects of a specific pesticide‐use scenario on the annual reproductive success of avian species of concern. A critical element in MCnest is the use of surrogate endpoints, defined as measured endpoints from avian toxicity tests that represent specific types ...

The interaction between natural organic matter in raw waters and pesticide residues: a three dimensional excitation–emission matrix (3DEEM) fluorescence investigation

by IWA Publishing  (Jun. 11, 2013)

This paper examines the interaction between dissolved natural organic matter and pesticide residues, both of which are found in raw water sources, using three dimensional excitation–emission matrix (3DEEM) fluorescence spectroscopy. It was observed that pesticide residue at 0.1 mg L−1 formed a complex with humic-like fluorophores ...

Quantifying the effects of pesticide exposure on annual reproductive success of birds

by John Wiley & Sons, Ltd.  (May 31, 2013)

The Markov chain nest productivity model (MCnest) was developed for quantifying the effects of specific pesticide‐use scenarios on the annual reproductive success of simulated populations of birds. Each nesting attempt is divided into a series of discrete phases (e.g., egg laying, incubation, nestling rearing), and results from avian toxicity ...

WSSA Pesticide Stewardship Series: Preparation and Oversight are Vital When Storing a Pesticide

by PRWeb  (May 1, 2013)

A landscaping and irrigation company was recently fined for storing pesticides in the same area as combustible materials – a decision that could have led to an explosion and fire. “Improper pesticide storage can expose both individuals and the environment to unintended harm,” says Fred Whitford, Ph.D., coordinator of the Purdue ...

WSSA Pesticide Stewardship Series: Always Be Diligent Concerning Personal Protective Equipment

by PRWeb  (Mar. 4, 2013)

This month pesticide safety educators, health professionals and other experts from around the U.S. will explore how to motivate pesticide handlers to use best practices concerning personal protective equipment (PPE). The discussion is part of a Pesticide PPE Seminar Series sponsored by the National Institute for Occupational Safety and Health ...

Sediment‐associated pesticides in an urban stream in Guangzhou, China: Implication of a shift in pesticide use patterns

by John Wiley & Sons, Ltd.  (Feb. 1, 2013)

Pesticide use patterns in China have changed in recent years; however, the study of the environmental fate of current‐use pesticides (CUPs) and their ecotoxicological significance in aquatic ecosystems is limited. In the present study, sediments were collected from an urban stream in the Chinese city of Guangzhou. Sediment‐associated legacy ...

The relative sensitivity of macrophyte and algal species to herbicides and fungicides: An analysis using species sensitivity distributions

by John Wiley & Sons, Ltd.  (Dec. 10, 2012)

Lemna spp. are the standard test species representing aquatic macrophytes in the current risk assessment schemes for herbicides and plant growth regulators in the European Union and North America. At a Society of Environmental Toxicology and Chemistry (SETAC) workshop on Aquatic Macrophyte Risk Assessment for Pesticides (AMRAP), a Species ...
