The relationship between toxin exposure and human health is significant, as exposure to harmful substances can lead to various negative health outcomes. Toxins from sources such as pollution, contaminated food, or chemicals can affect different body systems, potentially causing acute or chronic illnesses. For example, exposure to heavy metals or pesticides is linked to respiratory issues, neurological disorders, and cancer. Vulnerable groups, including children and pregnant women, may experience heightened risks. Understanding this relationship is vital for developing public health policies and mitigating exposure.
