air emission regulation

b - particle, and reverts to nitrogen In nature, radiocarbon is formed when high energy atomic particles called cosmic rays break down the atoms in the atmosphere into electrons, protons, neutrons and other particles. Some of the neutrons strike the nuclei of nitrogen atoms in the atmosphere..

Control of Air Pollution - Air pollution can be controlled either at source or at the dispersal stage of various pollutants. Although, the problem of controlling air pollution at source is not easy, it can be reduced to some extent by taking steps such as: Use of moder..

a) Checking the air pollution by strict imposition of laws on factories. b) Reducing vehicular traffic and encouraging public transport vehicles than individual vehicles. c) Use of unleaded petrol. d) Regular check of exhaust gases from vehicles to declare their status in respect of poll..

Natural resources that are limited in nature and are liable to be degraded in quantity and quality by human activities are exhaustible natural resources. Examples are forests, soil, wild animals, minerals, fossil fuels etc. The understanding of the environment and its proper conservation, has gain..

Physiological Action - (i) Nitrogen is non-poisonous. But animals placed in an atmosphere of nitrogen die due to asphyxiation (lack of oxygen). (ii) Nitrogen dilutes the oxygen of the air and helps in regulating the rate of respiration and combustion. Breathing in pure oxygen en..

When a gas or an air stream containing aerosols in the form of dust, fumes or mist, is passed between two electrodes, then, the aerosol particles get precipitated on the electrode. Electrostatic Precipitator The following practices also help in controlling air pollution: B..

These are compounds containing carbon and hydrogen only. The hydrocarbons involved in air pollution are gases (or those that are volatile) under ordinary conditions. The important sources of hydrocarbons in the natural environment are bacterial decomposition of organic matter, forest fire..

Question: What are cathode rays? How are they formed? Answer: Cathode rays are a stream of negatively charged particles. These particles called electrons are shot from the metal cathode of a discharge tube when an electric current is passed through a gas at a very low pressure. A dischar..

Reasons for Green House Effect - a) Out of total air pollutants to be 1 x 10 1 2 tons, man made pollutants are 5 x 10 8 tons. b) 25% of world's green house gases are released by USA which supports 4% of global population. c) Carbon monoxide accounts for 50% air pollution d) Susp..

Particulates - Particulate refers to 'finely divided solid or liquid particles suspended in air'. The size of particulates varies from about 0.0002 to about 500 (1 = 10 - 4 cm). In the polluted air, the number of particulate particles is as high as 10 1 1 per m 3 . In urban area..
