How We Assess Risks to Pollinators

EPA's pollinator risk assessment framework is part of its regulatory decision-making process for all pesticides, relying on a tiered process and focusing on major routes of exposure while distinguishing different types of pesticide treatment.

Film Permeability Determination Using Static Permeability Cells

The permeability of tarps to soil fumigant pesticides varies depending on the active ingredient chemical: dimethyl disulfide (DMDS), methyl bromide, chloropicrin, or other. The diffusion rate can be represented by the mass transfer coefficient (MTC).
