This activity provides 1.3 contact hours. carbon tetrachloride to reactive species is the initial key event in the development of carbon tetrachloride toxicity. Chronic exposure to carbon tetrachloride (CCl 4) - and sometimes acute exposure to very high concentrations - produces liver and kidney damage. Historically, CCl4 has been used in proton NMR spectroscopy. CCl 4 is highly toxic. Read about the steps in EPA’s risk evaluation process for carbon tetrachloride. This CSEM focuses on carbon tetrachloride toxicity. This educational case study is one in a series of self-instructional modules designed to increase the primary care provider’s knowledge of hazardous substances in the environment. To prepare the final risk evaluation, EPA reviewed extensive scientific literature, conducted modeling and other risk assessment activities, and collected toxicity, exposure, and hazard information from many sources. In compliance with continuing education requirements, all presenters must disclose any financial or other associations with the manufacturers of commercial products, suppliers of commercial services, or commercial supporters as well as any use of unlabeled product(s) or product(s) under investigational use. Fees: No fees are charged for CDC’s CE activities. The state of knowledge regarding the treatment of patients potentially exposed to hazardous substances in the environment is constantly evolving and is often uncertain.
