    Elemental bromine (Br 2) is toxic and causes chemical burns on human flesh. Inhaling bromine gas results in similar irritation of the respiratory tract, causing coughing, choking, shortness of breath, and death if inhaled in large enough amounts. Chronic exposure may lead to frequent bronchial infections and a general deterioration of health.

    This results in demineralised water which is not considered ideal drinking water. The World Health Organization has investigated the health effects of demineralised water since 1980. [32] Experiments in humans found that demineralised water increased diuresis and the elimination of electrolytes, with decreased blood serum potassium concentration.

    Water contaminated by aluminium or zinc cannot be treated in this way using a strong alkali as higher pHs re-dissolve the metal salts. Salt is difficult to remove except by reverse osmosis or distillation. Most portable treatment processes focus on mitigating human pathogens for safety and removing particulates matter, tastes and odours.

    Tungsten is water-soluble under certain conditions and may be found in dangerous quantities in water sources: May cause respiratory complications, and investigated as a potential carcinogen by the CDC Diclofenac: Anti-inflammatory drug Can be found in water treatment plant (WTP) effluents. Reported to be found in coastal waters as well

  9. Distilled water - Wikipedia

    en.wikipedia.org/wiki/Distilled_water

    Water purification, such as distillation, is especially important in regions where water resources or tap water is not suitable for ingesting without boiling or chemical treatment. Municipal water supplies almost always contain trace components at levels which are regulated to be safe for consumption. [14]
