TL;DR: The atmospheric input of pesticides to ecosystems seemed to be of higher relevance in the tropical study area than known from temperate regions.

TL;DR: Evaluating the leaching potential of eight pesticides in a Brazilian Oxisol found that atrazine, simazine and metolachlor were moderately leached beyond 15 cm soil depth, whereas all other compounds remained within the top 15 cm of the soil.

TL;DR: Investigation of 10 pesticides in two tropical soils of contrasting texture in the Brazilian Cerrado region near Cuiabá during an 80-d period indicated that a nonpoint pollution of ground water resources in tropical Brazil cannot be ruled out for these substances.

TL;DR: In a field experiment near Cuiaba, Brazil, alachlor, atrazine, chlorpyrifos, λ-cyhalothrin, deltamethrin, endosulfan-α, metolachlor and trifluralin were applied onto a Typic Haplustox as discussed by the authors, and 40 mm day−1 tracer solution (containing 5 g l−1 of the dye Brilliant Blue FCF and 0.015 M KBr) were applied in duplicate experiments over a period of 3 days, using either a

TL;DR: Pesticide dissipation was substantially enhanced for most pesticides in small microcosms relative to the large ones, and the persistence of the studied pesticides in aquatic ecosystems of the tropics is not substantially lower than during summer in temperate regions.
