TL;DR: A combined method using solid phase extraction (SPE), followed by solid phase microextraction (SPME) to concentrate different pesticides, including chlorinated, organophosphorus, triazines, pyretroids and chloroacetamides, present at trace levels in water samples, drawing attention to the need of pesticide monitoring programs in rivers.

TL;DR: Benthic organisms inside the greenbelt zone and inside the lower basin are threatened by the concentrations of glyphosate in sediment, and the risk of agricultural practices to aquatic biota is shown.

TL;DR: A combined two-year seasonal monitoring of Suquía River basin using both chemical parameters and biomarkers measured in Jenynsia multidentata aims to correlate external levels of contaminants with the response of oxidative stress biomarkers in this fish.

TL;DR: Changes in swimming behavior and cholinesterase enzymes activity in Jenynsia multidentata are evaluated to investigate the possible effects of these insecticides individually and in mixtures and to draw attention to the need of more studies on the potential ecotoxicological impact of pesticides and its mixtures at environmental relevant concentrations.

TL;DR: Given that both species responded to CF and the concentrations tested are environmentally relevant, the presence of this pesticide in freshwater systems could impose a risk for populations of both native fish studied at field.
