Le plus connu est le type de pollution qui résulte de la libération de particules … The negative effects of light pollution include the spoilage of the aesthetic environment of a place, creating disturbances in the ecosystem, and also harming the health of living creatures. The World Health Organisation (WHO) defined air pollution as limited to situations in which the outer ambient atmosphere contains materials in concentrations which are harmful to man and his environment. Some of the dangers leading to soil pollution are due to the fact that while number of earth’s inhabitants is increasing, the earth’s natural resources are by and large fixed as well as limited. Oceans of our planet act as a natural carbon sink. Thus banning the use of highly toxic and resistant pesticides or regulating their use only for special purposes under thorough monitoring can control soil pollution. Apart from these farm wastes, manure slurry, debris, soil erosion containing mostly inorganic chemicals are reported to cause soil pollution. In case of industrial pollutants, this can be achieved by undertaking various approaches at an early stage of process, design and development and selecting those methods which have minimum air pollution potential. 2. The most effective method of controlling air pollution is to prevent the formation of the pollutants or minimise their emission at the source itself. In some developed countries, thermal pollution abatement schemes are used to control water pollution. Burning of fossil fuels produces about 2/3 of SO2 present in air. Recently, one distillery in Gujarat is effective in treating 450,000 litre of water daily and generating energy equivalent to that produced by 10 tonne of coal. When human activity installs ugly barriers to this vision of open and clutter-free landscapes, it is called visual pollution. Green plants through evapotranspiration release huge amount of CO2. Purification of Water for Municipal Purposes: The processes used in the purification of water are as follows: The raw water is first aerated by bubbling compressed air. ADVERTISEMENTS: iii. 8. Types of Pollution Air Pollution. Mass media, educational institutions and voluntary agencies should be involved to achieve these objectives. Removal of Phosphorus by Electrolysis: In Norway, organic sewage is mixed with 10% of sea water and subjected to electrolysis to remove phosphorus from sewage water. pollution de l'air. The phenols so absorbed are broken down and can be utilized rapidly. and on environment. Municipal wastes have to be properly collected by segregation, treated and disposed scientifically. Plastic pollution is caused by plastic accumulation in the environment. Formulation of stringent pollution control legislation and effective implementation with powerful administrative machinery. The water is then allowed to stand in large settling tanks. Indiscriminate deforestation, digging for minerals, destruction of grazing land for human habitation have done irreparable damage to the land and even led to harsh climatic changes. 3. The method can remove 99.9% of chlorophenol from ground water at 5°C temperature. Periodically, the collected particles must be removed from the collecting surface. 14. But greenhouse gas is something that is at the top of that list. (iii) Pathogenic organisms excreted by animals. Higher temperatures also alter the composition of dissolved elements in water. The agents that bring about or cause this pollution are called pollutants. Effective treatment of domestic sewage by suitable biological and chemical methods and adopting modern techniques of sludge disposal. These are bad taste of drinking water, offensive odour from water bodies, unchecked growth of aquatic weeds in water, decrease in number of fish in fresh water, oil and grease floating on water surface. Yeast: Origin, Reproduction, Life Cycle and Growth Requirements | Industrial Microbiology, How is Bread Made Step by Step? 6. The gas close to the negative electrode is, thus, ionized upon passing through the corona (Fig.
