How should I search for inorganic substances that are harmful to human health?

Materials Project Materials Project Data/API

What websites or other ways to query or determine the properties of inorganic substances, especially toxicity?

Hi @burning,

We are not an authority on toxicity of inorganic materials, and the Materials Project does not offer this information.

Here are some resources that might be helpful, but I would encourage independent research:

European Chemicals Agency
PubChem (NIH), search engine including chemical toxicity
National Institute for Occupational Safety and Health, pocket guide of chemical hazards

See also http://www.ilpi.com/msds/ and https://ucsd.libguides.com/safety/government for links to other resources. In particular, many commercial entities have databases of materials safety data sheets (MSDS) such as Sigma-Aldrich.

Hope this helps,

Matt
