Toxicological harm can originate from various sources, including industrial chemicals, pharmaceuticals, environmental pollutants, and natural toxins. Pesticides, heavy metals like lead and mercury, and volatile organic compounds (VOCs) are common industrial toxins. Pharmaceuticals may cause harm if misused or if there are adverse drug interactions. Pollutants such as airborne particulates and waterborne contaminants pose significant risks to public health. Natural toxins include substances like venom, plant alkaloids, and mycotoxins.
