Effects of pesticides on soil fauna: Development of ecotoxicological test methods for tropical regions The impact of pesticides on the soil system is an issue of great concern. In the tropics, the environmental risk of pesticides is assessed using methods designed for temperate regions. This pioneer study shows that the toxicity of pesticides (here: two fungicides and an insecticide) measured under tropical conditions, e.g., higher temperature and different test species, can differ greatly from that determined for temperate conditions. Thus, a risk assessment of pesticides for tropical ecosystems based on existing toxicological data from temperate regions alone is not considered sufficient. Additional, adapted tests must be developed for tropical conditions.

Duas importantes questões foram levantadas neste estudo: (1) O efeito e destino dos pesticidas em solos de regiões temperadas podem ser diferentes em solos tropicais? (2) Os dados produzidos nas regiões temperadas podem ser usados para a avaliação de risco ambiental nos trópicos?

Soils are receptacles for a wide range of hazardous chemicals generated by human activities. Whether or not this contamination is deliberate, accurate toxicity assessments are important for health and economic reasons. Soil Ecotoxicology discusses the sources, fate, and transport of hazardous chemicals in soils. The fate (biodegradation and modeling) and the potential impacts of pesticides on soil ecosystems are emphasized, and methodologies for performing toxicity assessments are provided.
