Acute Toxicity - Terrestrial animals/ Human/ Aquatic animals

Adverse effects such as LD50 or LC50 for test exposures to animals; adverse effects to humans by test compounds; toxicity studieson freshwater aquatic species such as LC50 or EC50; all undertaken in short term tests.

Chronic Toxicity - Terrestrial animals/ Humans/ Aquatic animals

Toxicity studies undertaken in medium to long term time frames,such as NOAELs (No Observed Adverse Effect Levels), MATC (MaximumAdverse Toxicant Concentration), etc.

Phytotoxicity

Information on effects of substances to aquatic and terrestrial plants.

Carcinogenicity

Summaries of studies conducted by NCI/NTP, IARC, NIOSH, EPA.

Mutagenicity

Effects are reported such as gene mutations, chromosomal aberrations and DNA damage.

Reproductive and Developmental Effects

Reports of chemical effects on terrestrial animals or humans arereported. NOAELs may be provided if available.
