Soil pollution affects the health of humans, plants, and animals. Crops or plants grown on such contaminated soil absorbs toxic material from the soil and will decrease the agricultural output of a land. When animals or human beings consume these crops or plants the toxic material can pass into their body.
Heavy metals constitute an ill-defined group of inorganic chemical hazards, and those most commonly found at contaminated sites are lead (Pb), chromium (Cr), arsenic (As), zinc (Zn), cadmium (Cd), copper (Cu), mercury (Hg), and nickel (Ni).

Solution in my way :-

Cleanup (or remediation) technologies
available for reducing the harmful ef-
fects at heavy metal-contaminated sites
include excavation (physical removal of
the contaminated material), stabiliza-
tion of the metals in the soil on site,
and the use of growing plants to stop
the spread of contamination or to ex-
tract the metals from the soil
