What is pollution?

Pollution And Its Effect On Environment

What is pollution?

When something is added to the environment

which is very harmful, poisonous or fatal to the

animal, people surrounding it and other living

things is called as pollution. In simple term

pollution is a contamination by a chemical or

other pollutant that renders part of the

environment unfit for intended or desired use.

It is triggered by industrial and commercial

waste, agriculture practices, day to day human

activities and most notably, modes of

transportation and many the other sources.

Pollution has many forms; it may be chemical

substances or energy, such as noise, heat or

light.

Some most common types of

pollution: Pollution is a very voluminous term;

here we present some of the

common pollution?s.

1) Air Pollution:

Air pollution comes into picture due to the

accumulation of hazardous substances into the

atmosphere that danger human life and other

living matter. The most dominant player

responsible for pollution is automobiles; apart

from that the other causes are Combustion of

coal, Acid rain, Manufacturing buildings, Tobacco

smoke, Paint fumes, Aerosol sprays, Nuclear

weapons and wild fires. As far as effect of air

pollution is concerned, respiratory diseases tops

the chart of health problems. The second one is

heart diseases, it caused due to increased level

of carbon monoxide in the air. In addition to

that you can avoid a risk of Asthma, Eye

Irritation and a range of bronchial disease due

to air pollution. If statistics is to be believed, this

year air population segment will count for 80%

of premature deaths.

2) Water pollution: Water pollution causes due

to the introduction of chemical, biological and all

sort of physical matter into large bodies of water

that degrade the quality of life that lives in it

and consumes it. We can blame fertilizers,

pesticides, or petroleum derivatives for water

pollution. In addition to that the other

contributors towards water pollution are Waste

treatment facilities, mining, Pesticides,

herbicides and fertilizers, oil spills, refiners,

Failing septic systems, factories, Oil and

antifreeze leaking from cars, animal waste, Soap

from washing your car, house hold chemicals

and many more to count.

3) Noise pollution: Noise pollution is the

excessive noise that may disrupt the activity or

balance of human or animal life. The main

causes of noise pollution are machines,

transportation systems, motor vehicles, aircrafts,

and trains. In addition to that the other causes

of noise pollution are poor urban planning, the

indoor noise caused by machines, building

activities, music performances, and in some

workplaces also.

4) Solid waste: Solid wastes have a lion?s share

among total pollution. Mainly it is composed of

municipal solid waste (MSW), hazardous waste,

plastic waste and E-waste. MSW also called as

trash or garbage which is mainly composed of

everyday items that are discarded by the public.

Again MSW is of two types, biodegradable or

recyclable and non biodegradable. The non

biodegradable is more harmful in nature as it

can?t be degraded. Hazardous wastes always

pose a great threat to an environment. Under

RCRA in 40 CFR 261, hazardous wastes are

classified into 4 categories viz. ignitability,

reactivity, corrosivity and toxicity. Plastic wastes

always pose a great threat to the environment.

Due to its non degradable nature it always tops

the chart in pollution. E-Waste otherwise called

as electronic waste, waste electrical and

electronic equipment. E-Waste comprises of

office electronic equipment, television sets and

refrigerators, discarded computers,

entertainment device electronics and mobile

phones. All E-Waste poses lead, cadmium,

beryllium, or brominated flame retardants,

which trigger the pollution. Now E-Waste has

been a global concern and all effort is being

made to minimize it.

Grassroots effects of pollution on

environment: Pollution always harms to harm to

humans, pets, plants, trees, and aquatic life.

Acid rain, Eutrophication, Ozone depletion, haze,

global climate change, crop and forest damage

are the major effect of pollution on

environment. Pollution always takes away the

balance of the fragile ecosystems of earth.

Hence we should make all our efforts to control

our a waste and not to throw it into the ocean

or on the land.
