Acute Toxicology
PSL has extensive experience in GLP acute toxicology, including biocompatibility testing required for medical devices and the standard “six-pack” toxicology studies required by the EPA for registration and re-registration of pesticides. In fact, for each of the past five years, PSL has conducted more of these studies submitted to the U.S. EPA than any other laboratory in the industry. In addition, our studies have also been successfully submitted to other regulatory authorities all over the world. All studies are very competitively priced and are conducted with the highest levels of quality.
PSL has developed specific expertise in inhalation toxicology, conducting 250-300 acute exposures per year on liquids, powders and vapors.
