Toxic chemicals, as is obvious from the name, are chemical elements or substances which are
evil. They are usually the
by-products of
industries,
pollution and other wonderful human activities.
Acid rain may be produced when
oxides of
sulfur,
carbon, and
nitrogen from burning
fossil fuels combine with
water in the
air and produce
hazardous acids. Industrial
solvents,
hydraulic fluids,
herbicides and
radioactive wastes produced from
power plants are basically the
excreta we produce as the human
intestine of the
earth.
Toxic chemicals are often dumped in deep mines or undersea, where they can't harm humans, and cause only a slight problem for the other natural inhabitants of this earth. Sometimes they are simply dumped, like a waste recycling company in Cape Town was recently found: the company had been liquidated for several months, barrels of toxic waste simply stood around idly in the sun of day, not a half kilometre from a residential area.
