The effects of toxic chemicals on the human body can vary widely depending on the type of chemical, the dose, and the duration of exposure. Toxic chemicals can: - Cause acute toxicity, leading to immediate health effects like nausea, vomiting, and respiratory distress. - Lead to chronic toxicity, resulting in long-term health issues such as organ damage, cancer, and neurological disorders. - Affect specific systems in the body, such as the nervous system, respiratory system, and reproductive system.
