Immunotoxicology
study of toxicity affecting the immune system
Immunotoxicology (sometimes abbreviated as ITOX) is the study of the toxicity of foreign substances called xenobiotics and their effects on the immune system. Some toxic agents that are known to alter the immune system include: industrial chemicals, heavy metals, agrochemicals, pharmaceuticals, drugs, ultraviolet radiation, air pollutants and some biological materials. The effects of these immunotoxic substances have been shown to alter both the innate and adaptive parts of the immune system. Consequences of xenobiotics affect the organ initially in contact (often the lungs or skin). Some commonly seen problems that arise as a result of contact with immunotoxic substances are: immunosuppression, hypersensitivity, and autoimmunity. The toxin-induced immune dysfunction may also increase susceptibility to cancer.
The study of immunotoxicology began in the 1970s. However, the idea that some substances have a negative effect on the immune system was not a novel concept as people have observed immune system alterations as a result of contact toxins since ancient Egypt. Immunotoxicology has become increasingly important when considering the safety and effectiveness of commercially sold products. In recent years, guidelines and laws have been created in the effort to regulate and minimize the use of immunotoxic substances in the production of agricultural products, drugs, and consumer products.
This brief starts where responsible research should: with the source description of “Immunotoxicology” as study of toxicity affecting the immune system. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as study of toxicity affecting the immune system. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 26, 2026. The linked authority identifier is Q6005582. The Library of Congress control number is sh85064594. None of the 1 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
