Chemicals

Arsenic

• Clinician Brief: Arsenic - This clinician brief describes properties and sources of arsenic, routes of exposure, populations at risk, health effects, and clinical evaluation, management, and counseling of patients.

Dioxin and Dioxin-like Compounds

Training Videos

• Training Video: ATSDR Exposure Point Concentration Tool - In this webinar, you will learn how to use the exposure point calculations (EPC) tool by showing each step from importing data into the tool, trouble-shooting data errors, calculating the EPC, and interpreting EPC results for discrete sampling data. You will also learn (starting at minute 49) how to use the EPC tool to calculate benzo(a)pyrene (BaP) equivalents and dioxin toxicity equivalents (TEQs).
