TL;DR: In this paper, an 18-ha watershed in west Tennessee was used to characterize the fate of atrazine during a 12-month period after a pesticide application, and the results showed that atrazines in the upper 10 cm of soil followed a first-order decay trend, with only 1.88% of the initial concentration remaining 238 d after pesticide application.

TL;DR: Examination of the lumen-microvilli interface produced no evidence to indicate assimilation of the AuNPs used in the present study, and models developed from the present data predict that D. magna will amass a higher body burden of larger cationic AuNNP at high concentration exposures and larger anionic AuNps at low concentration exposures.

TL;DR: It appears that contaminant bioavailability can be altered by the addition of uncontaminated food, however, this phenomenon appears to be compound-specific and not broadly predictable.

TL;DR: In this paper, the authors showed an increase in chlordane solubility from 32 μg/L in pure (18 MΩ cm) water to over 400 μg/l in the presence of humic substances extracted from geologic material collected near a hazardous waste site in Memphis, TN.

TL;DR: Analytical analysis of the data revealed that particle uptake was influenced by a 4-way (plant species, plant roots, particle size, and dissolved organic carbon) interaction suggesting nanoparticle bioavailability was a complex result of multiple parameters.
