What are the impacts on our body if we take waterthat contains excessive amount of fluoride and arsenic?(both fluoride and arsenic is required)
Answers
Answer:
Millions of children are
exposed to excessive
amounts of fluoride through
drinking water contaminated from
natural geological sources. In
China, the burning of fluoriderich coal adds to the problem.
Small amounts of fluoride are
good for teeth; it is added to
toothpaste and, in some countries,
to drinking water. At higher
doses, it destroys teeth and
accumulates in bones, leading to
crippling skeletal damage. With
their bodies still growing, children
are most at risk.
Like fluoride, arsenic is widely
distributed throughout the earth's
crust, and is present in almost all
waters in very small amounts. In
certain areas, however, there are
dangerous levels of this toxin in
children’s drinking water. The
most tragic example is
Bangladesh, where thousands of
wells are causing a mass poisoning
of the population. Unsafe wells
are marked with red paint,
warning people that this water is
not for drinking.
Explanation:
Arsenic Standard Solution (10 ppm As): Dissolve 0.33 g of arsenic trioxide in 5 ml of 2M sodium hydroxide and dilute to 250.0 ml with water. Dilute 1 volume of this solution to 100 volumes with water.
