The toxic effects of a chemical may be local or systemic. Local injuries involve the area of the body in contact with the chemical and are typically caused by reactive or corrosive chemicals, such as strong acids, alkalis or oxidizing agents.

Toxicity information may be found in Material Safety Data Sheets, under the Health Hazard Data section, on product labels, in the Registry of Toxic Effects of Chemical Substances, or in many other sources listed in the MSDS page.

Toxic substances may be systemic toxins or organ toxins. A systemic toxin is one that affects the entire body or many organs rather than a specific site. For example, potassium cyanide is a systemic toxicant in that it affects virtually every cell and organ in the body by interfering with the cell’s ability to utilize oxygen.

TOXICITY is the ability of a substance to produce an unwanted effect when the chemical has reached a sufficient concentration at a certain site in the body. The more toxic a material is, the smaller the amount of it is necessary to be absorbed before harmful effects are caused.
