Pollution is the introduction of contaminants into the natural environment that causes adverse change
Types of Pollution
It can either be foreign substances/engergies or naturally occuring contaminats which pollutes the environment.
It can be from schools, restaurants, house, transportation, occupational, etc...
The release of chemicals and particals into the atmospher that causes discomfort, disease or death to humans, damage other living organisms such as food crops or damage the natural environment or built environment.
The air pollutants can in the form of solid particles liquid droplets or gases. In addition they may be natural or manmade.
Water pollution is the contamination of water bodies. It occurs when pollutants are directly or indirectly discharging pollutants in to the water, thus it effect plants and animals living in water. An estimated 1000, Indian children die of diarrheal sickness every day and also nearly 500 million people lack access to safe drinking water.
Soild pollution is caused by the presence of xenobiotic (human made) chemicals or other alteration in the natural soil environment.
It caused by:
- Industrial activity
- Agriculture chemicals
- Improper disposal of waste
This pollution causes congenital disorders. It effects the ground water, food chain, crop yield and soil fertility.
Noise pollution is a excessive, displacing human, animal, or machine created environmental noise that disrupts the activity or balance of human or animal life.
The noise can be from construction fields, transportation system, factories, etc...
It can effect both health and behaviour, physiological and psychological health, cause annoyance and aggression, hypertension, tinnitus, hearing lost, etc...
Air Pollution: Air Pollution is a significant risk factor for multiple health conditions including respiratory infections, heart disease, and lung cancer, according to the WHO. The health effects caused by air pollution may include difficulty in breathing, wheezing, coughing and aggravation of existing respiratory and cardiac conditions.
Water Pollution: It causes vomiting or diarrhea, a sick stomach, skin rashes, cancer(leukemia), reproductive problems(infertility), developmental problems(disabilities) etc...
Soild Pollution: Chronic exposure to chromium, lead and other metals, petroleum, solvents, and many pesticide and herbicide formulations can be carcinogenic, can cause congenital disorders. Mercury and cyclodiens kidney damage, PCB(polychlorinated biphenyl) are linked to liver toxicity and other such as head ache, nausea, fatigue, eye irritation etc...
Noise Pollution: It can cause cardio vascular effects, hearing loss, sleep disturbance, annoyance, agression also it can have a detrimental(harm) effect on animals.
Pollution control is a term used in environmental management. It means the control of emissions and effluents into air, water or soil, with out pollution control, the waste products from consumption, heating, agriculture, mining, manufacturing, transportation and other human activities, whether they accumulate or disperse, will degrade the environment. In the hierarchy of controls, pollution prevention and waste minimization are more desirable than pollution control.
