Read the following passage and write a short summary on it with help of the points given
below:

Contaminated or polluted soil affects human health through direct contact with soil or via inhalation of soil
contaminants which have vaporized. Potentially greater threats are posed by the infiltration of soil
contamination into groundwater aquifers. This tends to result in the development of pollution-related diseases.
Health hazards cause due to soil contamination very greatly depending on the pollutant type and vulnerability
of the exposed population. Constant exposure to chromium, lead, petroleum, many pesticides and herbicide
formulations can be carcinogenic and can cause congenital disorders or other chronic health conditions.
Industrial or man-made concentrations of naturally occurring substances, such as nitrate and ammonia
associated with livestock manure has also been identified as health hazards in soil and groundwater.
Chronic exposure to benzene at sufficient concentration is known to be associated with higher incidences of
leukemia. Mercury and cyclodines are known to induce higher incidences of kidney damage and some
irreversible diseases. Organophosphates and carbonates can induce a chain of responses leading to
neuromuscular blockage. Many chlorinated solvents induce liver changes, kidney changes and depression of
the central nervous system. There is an entire spectrum of further health effects such as headaches, nausea,
fatigue, eye-irritation and skin rash for the above cited and other chemicals. At sufficient dosages a large
number of soil contaminants can cause death by exposure via direct contact, inhalation or ingestion of
contaminants in groundwater contaminated through soil.
Points:
Health and groundwater problem – bad effects of chemicals – industrial and man-made concentration –
pollutants related diseases
Answers
here ya go,
Diseases caused by pollution lead to the chronic illness and deaths of about 8.4 million people each year. "However, pollution receives a fraction of the interest from the global community.[1] This is in part because pollution causes so many diseases that it is often difficult to draw a straight line between cause and effect.
There are many different types of pollution-related diseases, including those caused by air pollution, contaminated soil, water pollution and lacking water, sanitation and hygiene (WASH). Air pollution can be reduced.
associated with livestock manure has also been identified as health hazards in soil and groundwater which leads to water pollution and further growth of blue green algaee!
