Toxicity of pesticides on soil microbes: new risk assessment procedures for standardized risk assessment

Toxicity of pesticides onto non target organisms is an indispensable part of the pesticide regulatory framework. Although advanced protocols and tools have been developed and used for the assessment of the toxicity of pesticides on aquatic organisms and terrestrial macro-organisms this is not the case for soil microorganisms. Despite their pivotal role in soil ecosystem functioning, the assessment of the soil microbial toxicity of pesticides is still done using two out-of-date microbial tests, C and N transformation (OECD 217 and 216 respectively).  Methodological advances have drastically changed the scene in soil microbiology.  The implementation of ISO standardized tools in the environmental risk assessment of pesticides will enable the comprehensive assessment of the toxicity of pesticides on soil microbes. Our group has lead research work for the revision of the current regulatory framework and proposed new procedures for assessing the toxicity of pesticides on soil microorganisms. Arbuscular mycorrhizal (AM) fungi and ammonia-oxidizing microorganisms are used as toxicity endpoints in a tiered assessment approach spanning from in-vitro testing (Tier I) to field experimentation (Tier III). Our current focus is:

(i) on the development of in vitro tests in order to accurately assess the toxicity of pesticides on ammonia oxidizing microorganisms and AM fungi

(ii) on the study of the impact of pesticides on soil microorganisms looking at the food-web level (predators - prey system).
