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. See a full description of the database and our methodology.

Good Evidence Arrhythmias Cognitive impairment (includes impaired learning, impaired memory, and decreased attention span) / mental retardation / developmental delay Decreased coordination / dysequilibrium Decreased vision (includes blindness, retinopathy, optic neuropathy) Peripheral neuropathy Prostate cancer Psychiatric disturbances (disorientation, hallucinations, psychosis, delirium, paranoias, anxiety/depression, emotional lability, mood changes, euphoria) Pulmonary edema Seizures Spasticity / myoclonus	Limited Evidence Congenital malformations - general Testicular cancer

NOTE: 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 toxicant can be found at this link:

This link will direct your search to an external database, the Comparative Toxicogenomics Database (CTD). This database is different from, and complementary to, our database.

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.
