Solid Waste Pollution

Solid waste substances are those materials that become useless and hence waste after a short period of their use such as newspapers, bottles plastic bags, polythene, packing material, and garbage. The solid wastes are discarded after their use. The environmental pollution caused by these solid wastes which are increasing with the rapid rate of urbanization and industrial development. The main problem is the disposal of solid wastes.

Sources of Solid Wastes

Solid waste materials may be classified into two categories:

(i) Production of solid waste material at production centres.

(ii) Consumption centers after the use.

The production centres are small and large-scale industries, which also produce solid waste materials.

Types of Solid Waste Substance

These types of pollutants are divided into several types based on their sources:

(i) Mining wastes,

(ii) Agricultural wastes,

(iii) Industrial wastes,

(iv) Municipal wastes,

(v) Packing wastes,

(vi) Human wastes.

(vii) Anima wastes and

(viii) Radioactive waste.

The Problem of Solid Waste

There is a problem with the disposal of these wastes especially in developing countries because human labor is very expensive. To solve the problems, technologies and machines have been designed to recycle most of the solid waste materials paper cans, newspapers other paper wastes easily recycled. There are problems with recycling heavy metals.

Control of Solid Waste Pollution

There is an urgent need to control solid waste pollution. The following methods are suggested-(i) Recycling method, (ii) Burning of waste a Utilization for heat, (iii) Generating electricity, (iv) Composting of organic was for preparation of manures and biogas.

In big cities and towns, solid waste is purchased by kabaries, the nothing goes waste and throw away as waste material.

Noise Pollution

Meaning and Definition

If may be defined as the state of discomfort and restlessness caused to man by unwanted high-intensity sound known as noise. The noise pollution is both from natural sources and human activities sources.

1. Natural Sources. Cloud thunder, high-intensity rainfall, storm and hail storm, and heavy rainfall.
2. Human Activities Sources. Urban areas are automobiles, factories, industries, trains, aeroplanes, loudspeakers, radio, television, band-baza, religious functions, pressure cookers, cooler, election convincing, family celebrations, etc. Such activities are very frequent in urban areas. (Bed 2nd Year What are the main Pollution of Environment)

The production of unbearable high-pitched sound is called noise pollution. The type of pollution is included in air pollution.

Effects of Noise Pollution

There are two basic properties of sound-loudness and frequency. Loudness is the strength of the sensation of sound by the individual. The effects of noise pollution are of two types-Auditory effects and Non-auditory effects.

1. Auditory Effects include auditory fatigue and deafness. Deafness is caused by continuous noise exposure. There is a risk of deafness in the biggest cities like Mumbai, Delhi, Kolkata, Chennai, etc.
2. Non-Auditory Effects are interference with speech communication, irritation/annoyance, and loss of working efficiency and physiological disorders, etc. (Bed 2nd Year What are the main Pollution of Environment)

We are a noisy people, and every sentiment, be it religious, social, or family activity, is manifested in a noisy way. Loudspeakers and amplifiers are used without regard to the inconvenience or annoyance they may cause to a neighbor. “Dussehra” festival is approaching and many neighborhoods will suffer ten days of restless and disturbed nights. The “Ramlilas” is staged with loudspeakers at the highest pitch and the show goes on late into the night.

Another regular feature is the “Jagrans” in the name of devis, a disease that is spreading like a plague in many areas of cities. In temples, there may be heard bells and recordings of devotional songs over the loudspeakers. One wonders if God listens only through loudspeakers. This is at the cost of health and peace for many. There is a lot of noise nuisance during a marriage.

The processions stop from place to place for dancing and drinking and whatnot. This is the way to manifest one’s joy at the cost of others. Election time, the peace and calm fly away. It has an adverse effect on sick, old students who are preparing for examination or competition examinations. (Bed 2nd Year What are the main Pollution of Environment)

Noise pollution has psychological effects, it causes many behavioral changes among humans as well as animals. Disco music produces temporary deafness in the listeners. (Bed 2nd Year What are the main Pollution of Environment)

Control of Noise Pollution

Noise is measured in the unit of decibel (dB) which is a tenth of the largest “, the Bel. One decibel is equal to the finest sound that can be heard by the human ear. The following are the methods to control and reduce noise pollution :

1. At Source Control. The gadgets are to be developed to control no source.
2. Transmission Control. The room walls can be covered with some absorbers.
3. To protect exposed persons or workers. Devices such as ear plugs or ear muffs can be provided to workers in industries.
4. Plantation or Vegetation. Trees should be planned along high ways streets and other noisy places, the big trees are good for this purpose. (Bed 2nd Year What are the main Pollution of Environment)
5. Through Acts of Law. The noise pollution has now been included under Air Pollution Control Act.
6. The Education. By educating students and the public about noise nuisance through news media.

Radioactive Pollution

Radioactive substances are most toxic, as compared to organic poisons which have harmful and injurious effects. Nuclear war materials, test explosions, a great rush for power plants, and radio-isotope use in medicines, industry, and research are the main sources of radioactive pollution that could threaten or degrade the quality of the environment. There are two sources of radioactive pollution :

1. Natural Processes in Rocks and Soil Sources. Such as radium, uranium, thorium, potassium, carbon, etc.
2. Human Activities. Sources from atomic bombs, nuclear reactors, and other radiation sources-radio isotopes such as iodine, strontium, plutonium, cobalt, cesium, etc. A few radio-isotopes are concerned with environmental pollution such as argon, cobalt, cesium, iodine, krypton, strontium and plutonium and plutonium.

With biotic communities and ecosystems, these radioactive elements may become accumulated or dispersed, depending upon the biological activity of the element and the period of the radioactivity of the isotope. These are absorbed by plants, and ingested by animals which are deposited in bone tissues close to blood-forming tissue and it can then be passed on to humans through the milk and non-vegetarian food. (Bed 2nd Year What are the main Pollution of Environment)

The isotopes are accumulated in human tissues as well as those of plants and animals. The isotopes in human tissues cause serious health hazards to man. Man’s radiation exposure from artificial sources is already sufficient to produce serious disease problems such as bone tumors, genetic damage, and infant morality.

Prevention and Control Radioactive Pollution. There is a race the world over to develop atomic power, so experiments are being conducted by nations either in deserts or seas, or oceans. Such experiments pollute the atmosphere at regional and global levels. The ‘World Health Organisation’ and ‘United Nations Organization’ can play a significant role to check such experiments atomic energy may be used in industry and domestic purposes.

The education of medical science must include such environmental studies so that proper medical aid may be provided to the suffering. Researchers are to designed for preparing effective medicine to cure such patients.

Radioactive Protection Rules have been formulated in 1962. It is known as the Atomic Energy Act, of 1962.
