Organic compounds can have diverse effects on human health, ranging from benign to severely toxic. The toxicity of these compounds depends on their chemical structure, concentration, route of exposure, and duration of exposure. Some organic compounds, like benzene, are known carcinogens, while others, like formaldehyde, can cause irritation and respiratory issues. Moreover, compounds such as PCBs are persistent in the environment and can accumulate in the food chain, leading to long-term health effects.
