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 …

Neonicotinoids are widely used to control insect pests in agriculture. Their presence in the
environment can affect the health of non-target insects and aquatic animals. The behaviour …

Natural waters often contain complex mixtures of unknown contaminants potentially posing
a threat to marine communities through chemical interactions. Here, acute effects of the …

Pre-emergent herbicides are applied directly in the soil or over the straw in no-till systems
and can be retained, reducing the product's availability. The current study characterizes the …

Toxic effects of diuron and carbofuran on Paramecium caudatum were evaluated. Acute and
chronic tests were conducted with diuron and carbofuran active ingredients and their …

The environmental behavior of chlorpyrifos and endosulfan in soil was studied in the central–
western region of Brazil by means of a field experiment. Sorption was evaluated in …

Pesticides applied on agricultural lands reach groundwater by leaching, and move to offsite
water bodies by direct runoff, erosion and spray drift. Therefore, an assessment of the …

Sorption of non-ionic organic compounds to soil is usually expressed as the carbon-
normalized partition coefficient (K OC), because it is assumed that the main factor that …

Kinetic studies are of great concern for understanding the processes and parameters
involved in the sorption of pollutants by soils. Sorption kinetics of imidacloprid and diuron in …

The distribution of pesticides in soils with consequences for their mobility, bioavailability and
water contamination is mainly ruled by sorption processes. Such processes are seldom …
