Abstract:
Several pesticides are supposed to be neurotoxic for humans, consequently, they may also affect the auditory system. This review analyzes human and experimental animal studies testing the hypothesis that exposure to pesticides is associated with hearing loss. The literature on this topic is still sparse and methodological limitations of some papers evaluated are identified. As a whole, available data indicate a possible ototoxic action of pesticides, but alternative hypotheses could not be ruled out, also considering some confounders, such as the co-exposure to noise. Therefore, further studies are necessary in order to clarify the association between pesticides exposure and hearing loss. While awaiting more evidence, for precautionary action we recommend considering pesticides as possible ototoxic agents, in particular for vulnerable targets, such as pregnant women and children during early development.

Types of Toxins
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
