Environmental Testing

We provide a wide range of analytical chemistry, exposure assessment and pharmacokinetics support to industrial and government clients. We develop analytical methods for drugs and pesticides and their metabolites in tissues and biological fluids. We measure pesticides and their metabolites in air, dust, water, dermal and surface wipes, dosimeter garments and others. Good Laboratory Practices protocols are in place to support pesticide registration and clinical pharmaceutical investigations. Our study designs assess exposure to pesticides and other chemical pollutants. Product chemistry assays, pesticide residue determination, dislodgeable residue, re-entry exposure monitoring, and environmental fate studies are used. We offer analytical services in support of nutrition labeling under the Nutrition Labeling and Education Act and analytical methods development and routine testing for energetic residues in water, soil, biota and other media.
