Secondary pesticidal screening

Different methods of human exposure assessment vary with respect to the input data or information required and the degree of uncertainty associated with resulting estimates. Eor example, the film-thickness approach to dermal exposure assessment is a screening-level methodology that assumes a uniform layer of material (e.g., a liquid consumer product) is on the skin, and that a portion of the material in this layer is absorbed, per the dermal absorption characteristics of the chemical. In contrast, dermal exposure assessment and percutaneous absorption methods can include metrics that account for time-dependent exposure and absorption processes. Eor example, in the case of secondary dermal contact with chemicals on surfaces (e.g., transfer of pesticide residues from... 

States than are predicted by the most extreme estimates to die from cancer secondary to pesticide residue contamination. These are serious problems that have always plagued mankind because it is extremely difficult to detect bacterial contamination during meat processing. However, biotechnology has developed some rapid screening tests to improve the detection of contaminated food before it reaches the consumer. This is another spin-off that has minimal risk and almost immediate benefits.
