New EFSA guidance on agchem degradation in soil
The European Food Safety Authority (EFSA) has issued new guidance on measuring soil degradation rates of pesticides. It is aimed primarily at risk assessors and industry applicants. The document provides a method for evaluating studies that measure the time required for the actual degradation of 50% of a chemical pesticide and its transformation products in soil, known as the DegT50 value. This value is “critical information” for the safety evaluation for pesticides, the EFSA says. The Authority is to explain its methodology to around 65 stakeholders at a meeting in June. The guidance is on the EFSA website at: www.efsa.europa.eu/en/efsajournal/pub/3662.htm.
