Mercury is a very toxic and dangerous substance. It is poisonous in all forms - inorganic, organic or elemental. Mercury is a proven neurotoxin. Inhaling mercury vapours can severely damage the respiratory tract. Sore throat, coughing, pain or tightness in the chest, headache, muscle weakness, anorexia, gastrointestinal disturbance, fever, bronchitis and pneumonitis are symptoms of mercury toxicity. Health concerns should be reason enough for us to properly manage its imports and disposal.
