Types of pollution and Causes of pollution: May 2010

Sewage Pollution

Sewage Pollution

We usually think of water pollution, when we think Sewage pollution . It is most visible form of pollution to the naked eye. It is most smelling to the naked nose. Sewage pollution consists of raw and or partially treated domestic waste. of kitchen.
Sewage water also contains both liquid and solid wastes from human beings beside the waste. of kitchen. It also contains everything of the household garbage that goes down the drain into the house sewer. The soap water, chemicals, sink and garbage drainage, and water from washing room machines will be found in this type of sewage pollution.
Detergent foam adds to sewage pollution, which is formed due to detergents used for washing cloths and dishes.
. Foam appears in the sewage treatment plant and gets scattered all over the area. It bubbles in the kitchen sinks and the shower bath. contained some detergent pollution.
Rivers,canals drains are .covered with foam for some time.. mountains of foam are noted at the sewage treatment plant .
Any agent that promoted cleaning—even soap—can be called a detergent. But the products used as detergents are chemical compounds—synthetic product sometimes called syndics (synthetic detergents) these are used in the home and in industry for cleaning purposes. The detergent mess was due to a chemical called ABS, once used in over 80 percent of the washing products. ABS is chemical shorthand for alkyl benzene sulfonate..

DIABETES due to pollution

DIABETES due to pollution Scientists now feel that pollution may trigger diabetes. In a recent Publication Cambridge scientists Oliver Jones and Julian griffin mention possible link between pollutants and Diabetes. In the past research it has been shown that even thin persons can have Diabetes if they have high levels of persistent high level of organic pollutants {POPs }in their blood. These are toxic to humans and wildlife. POPs became prominent after introduction of DDT synthetic pesticide

Smoke emissions from an industrial factory causing air pollution.

Smoke from a factory in Himachal Pradesh , one of the main causes of pollution. It

engulfs the whole factory itself

and the area of location of factory, Imagine.

It is not possible to breathe within many miles

of factory location. This pollution causes all type of the villagers in the area to suffer health problems. This

air pollution causes pollution asthma to all living in the area.

What can we do without any trouble

Save Water

Do not throw any poisonous substances in the drains of our house to avoid Water contamination.

Repair the leaking taps, pipes, faucets and other sources of water.

Taking the bath can be replaced by taking a shower and the shower water can be used for gardening Do not. Do the laundry or dishes until the washer is full.

Save Air

Use the lead free gasoline.

Try to use the public transport or a car pool .

Plant trees , plants, bushes in the neighborhood.

Do not burn leaves and other garbage.

Save Ears

Use the car horn only in emergency.

Keep the volume of tv and radio low.

Check the car and motorbike not make the noise They should lead free gasoline .

The pollution affects every one equally. It is only we who can help us. We are creating it, we can stop it.

Setback to pollution control

Euro IV norms were effected two months back in the country. New specifications were registered at any Regional Transport Office (RTO) in the city. Not a single truck or bus has been rolled out. But first lot of heavy vehicles with new emission norms will only be supplied by July,
Although Euro IV compliant diesel is being sold across the capital ,reducing pollution levels, by improving air quality can not be thought of.
,
Commonwealth Games in October is causing worry about pollution levels to the Delhi government. Because heavy vehicles like trucks and buses are major contributors to air pollution in the city.

Role of Ozone in Increasing Pollution

Role of Ozone

Ozone is a gas. It is concentrated in layer 25-30 Km above the earth’s surface. Ozone acts as a shield, protecting the earth from the damaging effects of ultraviolet radiation from the sun..

It is thinning or complete loss of layer of Ozone .It is 10 to 50 km above the earth.

Ozone absorbs the electromagnetic radiation in the ultraviolet region. Thus ozone prevents these rays to reach earth. Ozone shield appear to be breaking down.This is matter of serious concern. A depletion of ozone above the Antarctic was observed by the British Antarctic Survey in 1977 and the first ‘hole’ discovered there in 1985 (a ‘hole’ is where ozone depletion is over 50 per cent). This hole, which appears each spring, develops when very low temperatures allow the ozone to be destroyed in a chemical reaction involving chlorine. The main sources of chlorine are:

The release of chlorofluorocarbons (CFCs), especially from aerosols, by humans into the atmosphere(a long-term effect)

From major volcanic eruptions (a short-term effect).

The first observed ‘hole’ over the Arctic followed the coldest-ever January of 1989.Since then depletion's have increased annually over northern Europe.

People are advised to use sunblocks and to limit exposure to direct sunlight. Here the Ozone {triatomic oxygen} is formed by the action of ultraviolet radiation on the oxygen

In the atmosphere. High level of ultra violet radiation can be harmful to animal and plant

Motor vehicle exhaust fumes create increasing amounts of ozone close to the earth’s surface. Ultraviolet radiation is responsible for sunburn and skin cancer, snow-blindness, cataracts and eye-damage, aging and wrinkling of skin, and reduced immunity to disease.

High asthma levels in children,have been linked to traffic pollution.

Fat people are more affected by Ozone in air

Exposure to the Ozone is known to cause a temporary drop in the lung function in many people. In a study body weight influenced Lung function after acute Ozone exposure. The study found that ozone response was greater in heavy persons.

Oxygen Bars: Do they reduce health damage due to pollution

Oxygen Bars are supposed to improve health and well-being.

Oxygen bars started spreading in nineties in Japan, California & Britain. In trade fairs, health clubs and airports.. Now these are opening in France. These are being marketed as anti- stress, anti-fatigue, and anti-depression help. One of such bar has been opened in a beauty institute..The health inspectors are trying to determine the merits and demerits. Of sniffing O2. Some experts are of the opinion that the the effect is more psychological than technical.

The oxygen bars offer the sniffers up to 95 % of oxygen compared to 21% of atmospheric oxygen in the cities due to severe pollution.

Sulfur Dioxide -most dangerous gaseous pollutants

Sulfur Dioxide is one of the most dangerous gaseous pollutants for the mankind The lungs and mans respiratory system are affected by it . It causes strong irritation to the eyes and skin. It even destroys the enamel on teeth. Many effects of this gas on man are permanent and irreparable.

Burning of oil and coal are the main reason for the production of this gas. Different kinds of coal and oil have different amounts of sulfur That is reason more sulfur dioxide will produce from the burning. If coal with a high sulfur content is burned,more sulfur dioxide will be produced. and enter the atmosphere as sulfur dioxide gas.

Effects of Air pollution on Humans

Effects of Air Pollution to

1. Humans .
2. Animals
3. Vegetation
4. Material
5. Atmospheric System
Effects of Air pollution on Humans
Most of people spend their time indoors, there is Air pollution in homes, offices, shopping malls & areas.
Air Pollution mainly damages the Respiratory system.
This damages can be studied through scientific ways.

Clinical
Epidemiological using the health records
Theological using animals

The Effects of Air Pollution on Human & Animals depend on exposure time.
If the time of Exposure is small in the high concentration the effect will be mild.
But if the exposure is for extended period, in the low concentration, the effect can be bad.
Effects of Air Pollution on vegetation is of many kinds. Sulfur dioxide can damage crops & trees. Hydrogen fluoride & nitrogen dioxide can damage ornamental plants & fruit trees. Ozone & ethylene cause damage to vegetation.
Effect of Air pollution to the Materials it damage ferrous Metals Nonferrous Metals like Aluminum, Copper, Silver, Nickel &
Building Materials -Paint, leather, Paper, Textile, Dyes, Rubber,
Ceramics
Effect of Air Pollution to the Atmosphere.
It changes the dynamics of atmosphere through the long & short wave radiation Processes
Carbon dioxide increases the temperature of surface due to which the temperature of the atmosphere will increase ,cause serious environment effects.
