Pesticides are intensively used in agriculture, and much effort is expended to manage and
reduce possible deleterious effects on the environment. The soil compartment has a major …

This special issue presents a collection of papers covering the environmental fate, effects,
and risk of pesticides in tropical environments, which is expected to facilitate improved …

Pesticide soil/solution distribution coefficients (Kd values), commonly referred to as pesticide
soil sorption values, are utilized in computer and decision aid models to predict soil mobility …

The present work investigated the direct and indirect photolysis of pesticide residues
(atrazine, imazaquin, iprodione), in aqueous solutions and under UV–visible radiation (280 …

Highly weathered soils represent about 3 billion ha of the tropical region. Oxisols represent
about 60% of the Brazilian territory (more than 5 million km2), in areas of great agricultural …

Electrochemical properties of soils are very important for the understanding of the physico-
chemical phenomena which affect soil fertility and the availability of nutrients for plants. This …

Sorption− desorption interactions of pesticides with soil determine their availability for
transport, plant uptake, and microbial degradation. These interactions are affected by the …

Aqueous batch-type sorption− desorption studies and soil column leaching studies were
conducted to determine the influence of soil properties, soil and suspension pH, and ionic …

Sorption, persistence, and leaching of the enantiomers of the herbicide imazaquin, S-
imazaquin and R-imazaquin, in two soils under different application regimes were studied …

The objective of this study was to investigate the behavior of sorption and desorption of the
herbicides atrazine (6-chloro-N 2-ethyl-N 4-isopropyl-1, 3, 5-triazine-2, 4-diamine) and …
