Aluminium

Toxicity

   Differs only slightly toxic effects, but many are water-soluble inorganic compounds of aluminum remain in solution for a long time and may have harmful effects on man and warm-blooded animals through drinking water. The most toxic chlorides, nitrates, acetates, sulfates, etc. For human toxicity if swallowed provide the following doses of aluminum compounds (mg / kg body weight): aluminum acetate - 0,2-0,4; aluminum hydroxide - 3,7 - 7,3; alum - 2,9. First and foremost affects the nervous system (stored in the nervous tissue, leading to severe disorders, central nervous system functions). However, the properties of aluminum neurotoxicity were examined from the mid 1960's, as the accumulation of metal in the body prevents the mechanism of its excretion. Under normal conditions, the urine can be allocated to 15 mg element per day. Accordingly, the greatest negative effect is observed in people with impaired renal excretory function.

   The ratio of aluminum content in the water utility and water use is 0.2 mg / liter. At the same time this MAC can be increased to 0,5 mg / l chief state sanitary doctor of the territory for a particular water system.
