Question

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

below: (3)

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​

Answer 1

Answer:

number of soil contaminants can't death by exposure via direct contact, inhalation or ingestion of point.
