Environmental pollution

POLLUTION CONTROL AND DISASTER MANAGEMENT

Environmental Pollution  Environmental pollution is any discharge of material or energy into water, land, or air that causes or may cause acute (short-term) or chronic (long-term) detriment to the Earth's ecological balance or that lowers the quality of life. 

Types of pollution which affect the environment are:

Air pollution.Water pollutionNoise pollutionSoil pollutionMarine pollutionThermal pollutionRadiation pollution.

AIR POLLUTIONContamination of air by smoke and harmful gases, mainly oxides of carbon, sulfur, and nitrogen.

Basically these gaseous substances tend to interfere with human comfort , welfare and causes environmental damage. Air pollution causes acid rain, ozone depletion, photochemical smog and other such phenomenon.

EFFECTS

PLANTS• Affects the movement of the stomata• Photosynthesis• Growth of the plant.• Too much exposure to sulphur dioxide

causes bleaching of the leaf pigment.• High concentration of carbon

monoxide leads to premature falling of leaves, curling, etc.

CONTROLPUBLIC AWARENESSINDUSTRIAL GASES SHOULD BE TREATED BEFORE DISCHARGE IN THE ATMOSPHERE

USE OF ENVIRONMENTAL FRIENDLY FUELS, SUCH AS GOBAR GAS, LPG, NATURAL GAS,ETC

RAISING OF GREEN BELTS SHOULD BE PROMOTED.

WATER POLLUTION• THE CONTAMINATION OF WATER WITH UNDESIRABLE SUBSTANCES WHICH MAKE IT UNFIT FOR USAGE IS TERMED AS WATER POLLUTION.

EFFECTS

HUMAN HEALTHCAUSES VARIOUS DISEASES TO THE

CENTRAL NERVOUS SYSTEMCAUSES DAMAGE TO LIVER , BRAIN

AND KIDNEY. IT CAUSES VARIOUS DISEASES LIKE

DIARRHOEA, ABDOMINAL PAINS, SKIN RASH, JAUNDICE, FEVER, ENLARGED LIVER,ETC.

TO AN EXTENT IT MAY ALSO CAUSE DEATH.

PLANTS EXCESSIVE USE OF FERTILIZERS ON

CROPS MAY CAUSE SOME AMOUNT TO BE RETAINED IN THE SOIL WHICH IS WASHED AWAY DURING RAINS AND REACHES THE NEAREST WATER BODY.

EXCESS AMOUNT OF NITRATE PRESENT IN WATER CAUSES THE GROWTH OF UNWANTED PLANTS.

CAUSES EUTROPHICATION.UNWANTED PLANTS REDUCE THE OXYGEN

SUPPLY TO OTHER AQUATIC PLANTS. POLLUTED WATER ALSO CONTAINS HIGH

CONCENTRATION OF METALS WHICH MAY BE TOXIC FOR PLANTS AND HAMPERS THEIR GROWTH.

ANIMALSAQUATIC ANIMALS ARE DIRECTLY

AFFECTED BY WATER POLLUTION.

THE HARMFUL CHEMICALS MAKES THE SURVIVAL OF THE AQUATIC ANIMALS VERY DIFFICULT.

DUE TO THIS A LARGE NUMBER OF AQUATIC SPECIES HAVE BECOME EXTINCT.

DRINKING POLLUTED WATER COULD BE VERY POISONIOUS AND MAY CAUSE SEVER DISEASES AND ALSO DEATH.

CONTROL INDUSTRIAL WASTE SHOULD BE

TREATED IN ORDER TO REDUCE TOXICITY.

NON BIODEGRADABLE WASTE MATERIAL SHOULD NOT BE DUMPED.

HUMAN ACTIVITIES SUCH BATHING, WASHING IN RIVERS, THROWING CARCASSES AND IMMERSING IDOLS SHOULD BE STOPPED.

PUBLIC AWARNESS.
