Where can I find toxicity data?
Toxicity data sources
- EPA’s National Air Toxics Assessment (NATA).
- EPA’s Office of Pesticide Programs (OPP) Acute Chronic and Reference Doses Table lists.
- The Agency for Toxic Substances and Disease Registry (ATSDR) Minimum Risk Levels (MRLs).
How do you check for chemical toxicity?
Toxicity can be measured by the effect the substance has on an organism, a tissue or a cell. We know that individuals will respond differently to the same dose of a substance because of a number of factors including their gender, age and body weight. Therefore a population-level measure of toxicity is often used.
Where can information regarding the specific safety concerns of chemicals be found?
Where can information regarding specific chemical safety be found? MSDSs.
What are the regulatory agencies that deal with toxicology issues?
The Agency for Toxic Substances and Disease Registry (ATSDR), based in Atlanta, Georgia, is a federal public health agency of the U.S. Department of Health and Human Services.
What is toxicity data?
Results in test subjects are predictive of human responses and test subjects are sensitive to the effects of the substance. In toxicity tests of a substance involving several species, data obtained with the most sensitive species are often used for making health-hazard estimates.
What is toxicological data?
Toxicological data provide the basis for evaluating the potential health risks of chemicals to humans. Information from human and animal studies is used to characterize the nature of the toxic effects of chemicals and to predict their risk to human health under given exposures.
What are the 3 types of toxicity?
Types of toxicity There are generally three types of toxic entities; chemical, biological, and physical. Chemicals include inorganic substances such as lead, hydrofluoric acid, and chlorine gas, organic compounds such as methyl alcohol, most medications, and poisons from living things.
Which part of an HCS label provides information on protective measures?
Precautionary Statements describe recommended measures that should be taken to minimize or prevent adverse effects resulting from exposure to the hazardous chemical or improper storage or handling.
How can workers get information about the chemicals in a product?
What government agency in California sets the Permissible Exposure Limits (PELs) of chemicals? How can you get information about the chemicals in a product? Safety Data Sheets. SDSs should be consulted by only after an emergency such as a spill, fire, or explosion.
Which chemicals are included in the Atsdr list of hazardous substances?

What is toxicity test data?
Toxicity tests are an attempt to measure toxicity in a sample by analyzing the results that the exposure produces on standard test organisms (Kroll, 2007).
