TL;DR: It is deducted that the contamination of water resources is predominantly caused by non-point pollution of pesticides used in intensive cash-crop cultures of the Cerrado area, and a continuous monitoring of pesticide concentrations in water resources of this tropical region is necessary to detect the longer term contamination trends and developing health risks.

TL;DR: The environmental behavior of metolachlor and diuron was studied in the Central-western region of Brazil, by means of a field study where six experimental plots were installed The soil was classified as a Latosol, and the soil horizons were characterized as mentioned in this paper.

TL;DR: A study on the presence of herbicides, namely simazine, metribuzin, metolachlor, trifluralin, atrazine and two metabolites, deisopropylatrazine (DIA) and DEA, was performed in ground and surface waters from Primavera do Leste region, Mato Grosso state (Middle West of Brazil).

TL;DR: Acetamiprid and thiamethoxam showed low sorption coefficients, representing a high risk of surface and ground water contamination, and the partition coefficient normalized to soil organic carbon (K oc) was calculated.

TL;DR: The p,p'-DDT is moving slowly downward in the soil profile, however, the levels of this contaminant are high enough to present risk to underground waters.
