What parts of the body can hazardous substances affect?  The effect obviously depends on the specific substance and how it entered the body.  Some typically effects are;

Brain & nervous system – Exposure to hazardous substances can affect the brain causing confusion, delirium and unconsciousness. Unusually high levels or prolonged exposure can, depending on the substance, interrupt the nervous system causing a variety of conditions such as seizures, drowsiness and numbness of the hands and feet.

Mouth – Swallowing hazardous substances can burn lips, mouth and food passages.

Eyes – Eyes are very sensitive organs and easily damaged. Exposure to hazardous substances can cause chemical burns, dryness and irritation.

Blood – Once in the body, hazardous substances may penetrate the bloodstream causing damage to tissues and vital organs of the body.

Skin – Certain hazardous substances such as corrosives may be absorbed through the skin and cause burns. Solvents and detergents may cause dermatitis.

Lungs – Exposure to certain hazardous substances can cause severe respiratory distress and a variety of lung diseases from asthma to cancer.

Heart – Exposure to hazardous substances can disturb the action or rhythm of the heart.

Liver/kidneys – The liver and kidneys can sustain damage as they struggle to filter the hazardous substance.

Digestive system – Hazardous substances in the digestive system can cause vomiting, abdominal pain and diarrhoea.
