Toxicant and Disease Database

The CHE Toxicant and Disease Database is a searchable database that summarizes links between chemical contaminants and approximately 180 human diseases or conditions. Diseases and or toxicants can be viewed by utilizing the search options below. In 2025, we have also added links to information available in the Comparative Toxicogenomics Database (CTD). See a full description of the database and our methodology.

Cirrhosis

Causes Grouped by strength of evidence

Strong Evidence aflatoxins carbon tetrachloride chlorinated naphthalenes ethyl alcohol (ethanol) PCBs (polychlorinated biphenyls), not otherwise specified tetrachloroethane TNT (trinitrotoluene)	Good Evidence arsenic halothane solvents trichloroethylene (TCE)	Limited Evidence 1,1,1-trichloroethane formaldehyde hydrazines N-nitrosodimethylamine pesticides selenium

Notes

Organic solvent exposure in shipyard workers, painters, and printers has been associated with cirrhosis.

ADDITIONAL DATA: The toxicant–disease relationships shown above were last updated in 2011. The relationships shown here are still valid, but additional research has been conducted since that time. Additional research on this disease can be found at this link:

More information about sources and methods

CHE’s Toxicant and Disease Database evaluates existing evidence and categorizes that evidence based on its strength. It is constructed using expert judgment and epidemiological causal inference.
The CTD, in contrast, is a continually updated resource that presents information on a broad range of literature on chemical-disease relationships. It also provides data on genes, biological processes, and phenotypes related to chemicals and diseases. It does not categorize information based on strength of evidence, include an expert judgment process, or draw causal conclusions about toxicant-disease relationships.
The link we have provided on this page goes directly to CTD's curated results, which are a subset of the information available through CTD. Curated results in CTD are those for which studies are available on the toxicant-disease relationship.
