Disposition of Atrazine Metabolites Following Uptake and Degradation of Atrazine in Switchgrass

International Journal of Phytoremediation, 2013
Extensive use of the agricultural herbicide atrazine has led to contamination of numerous ground and surface water bodies. Research has shown that it can have a variety of negative impacts on numerous non-target organisms in the environment. Phytoremediation is one strategy that has been studied to remove atrazine contamination. This paper investigates

Fitness drift of an atrazine‐degrading population under atrazine selection pressure

Environmental Microbiology, 2008
Summary Pseudomonas sp. ADP harbouring the atrazine catabolic plasmid ADP1 was subcultured in liquid medium containing atrazine as sole source of nitrogen. After approximately 320 generations, a new population evolved which replaced the initial population.

Fate of Atrazine and Atrazine Degradates in Soils of Iowa

1996
Several studies have been conducted to investigate the fate of atrazine (ATR, 2-chloro-4[ethylamino]-6[isopropylamino]- s -triazine) and major degradation products of ATR in soils of Iowa by using laboratory radiotracer studies, field lysimeters, and a field-scale approach.

ATRAZINE REMEDIATION IN WETLAND MICROCOSMS

Environmental Toxicology and Chemistry, 2001
Abstract Laboratory wetland microcosms were used to study treatment of atrazine in irrigation runoff by a field-scale-constructed wetland under controlled conditions. Three experiments, in which 1 ppm atrazine was added to the water column of three wetland, one soil control, and one water control microcosm, were conducted.

Atrazine and cancer

European Journal of Cancer Prevention, 2013
The aim of this study was to evaluate the conflicting reports from the Environmental Protection Agency and the Scientific Advisory Panel (Panel) on the carcinogenicity of atrazine in order to determine whether the results from epidemiologic studies support a causal relationship between atrazine and any specific cancer.

Assessment of human exposure to atrazine through the determination of free atrazine in urine

Bulletin of Environmental Contamination and Toxicology, 1990
Studies on metabolism and excretion of atrazine in man are not available in the literature. The present study has investigated human exposure to atrazine during its industrial production by means of assessment of ambient exposure and determination of free atrazine in urine.

Bioremediation of atrazine-contaminated soil by repeated applications of atrazine-degrading bacteria

Applied Microbiology and Biotechnology, 1999
Bioaugmentation has previously been unreliable for the in situ clean-up of contaminated soils because of problems with poor survival and the rapid decline in activity of the bacterial inoculum. In an attempt to solve these problems, a 500-l batch fermenter was investigated for its ability to deliver inoculum repeatedly to contaminated soils via ...

SALIVARY CONCENTRATIONS OF ATRAZINE REFLECT FREE ATRAZINE PLASMA LEVELS IN RATS

Journal of Toxicology and Environmental Health, Part A, 1998
The protein binding of atrazine in plasma and its effect on salivary excretion of atrazine was determined in male Sprague-Dawley rats. The degree of protein binding of atrazine was determined at 3 steady-state plasma concentrations, 50, 150, and 250 microg/L, using an ultrafiltration technique. In total, 48 arterial blood samples were collected from 18

Residual tembotrione and atrazine in carrot

Journal of Environmental Science and Health, Part B, 2016
Carrot (Daucus carota L.) is a vegetable crop that is grown throughout the year across various regions of Brazil in rotation or in succession to other cultures. Herbicide residual effect has emerged as a concern, because of the possibility of carryover.
