FATE, TRANSPORT, AND MIXTURE TOXICITY OF TRANSGENIC BACILLUS THURINGIENSIS CORN (ZEA MAYS) AND ASSOCIATED INSECTICIDES
… in groundwater or soil pore water. No acute toxicity was observed to any species when exposed to the Cry1Ab protein in corn plant leaf tissue, therefore little risk was anticipated. Non-target species exposed to clothianidin resulted in limited ecological risk from field exposures. Tefluthrin …

SOIL MICROBIAL AND ECOSYSTEM SERVICE RESPONSES TO METAL MIXTURES IN CANADIAN SOILS
… by environmental scientists when assessing metal toxicity in soils is the wide difference in toxic effects between laboratory spiked soils and field contaminated soils. Also, since contamination occur as mixtures, researchers are faced with understanding metal mixture interactions in soil to help …

Molecular docking and geographical information systems as tools to assess the potential impact of veterinary medicines on non-target organisms and the environment
… organisms. VMs enter the environment in mixtures, potentially having additive effects. Traditional ecotoxicology tests are used to determine the lethal and sometimes reproductive effects on freshwater and terrestrial organisms. However, organisms used in ecotoxicology tests can be …

Synthesis, Fractionation, Characterisation and Toxicity of Naphthenic Acids from Complex Mixtures
… associated polluted production waters, complex mixtures of acids, known historically as naphthenic acids (NAs), have achieved prominence. This is particularly because NAs have been designated a toxicant class of concern in the oil sands process-affected water (OSPW) that has accumulated in vast …

Measurement of the cellular oxidative potential and cytotoxicity of ambient pm2.5 – an assessment of toxic pm2.5 chemical components and their sources in the midwest US
… for the associations among PM 2.5 OP, cytotoxicity, and PM2.5 components. The biological relevance of PM2.5 chemical OP assays hasn’t been well established. The first research objective in this dissertation is to link chemical OP assays with cytotoxicity. PM2.5 samples were collected from …
