control of photochemical smog

Photochemical smog occurs due to the action of sunlight on air pollutants, generating photochemical reactions. The principal constituents of the photochemical smog are gaseous hydrocarbons (leading to ozone formation) and oxides of nitrogen (NO x )..

Smog - Smog is mixture of smoke and fog containing particulates. Two types of smog exist, classical or original smog and the more recent photochemical smog..

Carbon monoxide is an extremely poisonous gas: a concentration of 1 part of CO in 800 parts of air can cause death within half-an hour. Water vapours containing sulphur dioxide condense on smoke particles forming chemical smog. Smog causes respiratory troubles. The unburnt hydr..

When pollutants like hydrocarbons and nitrogen oxides combine in the presence of sunlight, smog is formed. This is a mixture of gases and since it is formed by photochemical reactions, it is called the photochemical smog. The word 'smog' is derived..

Air pollution can be controlled by different methods depending on the source and the pollutant. The different methods are: One of the major causes of air pollution are the automobiles. The fuels being used should be lead-free as this will reduce the level of lead in the atmosphere. The ca..

Processes by which substances are transformed to one or several products are called chemical reactions. Chemical processes that occur in the presence of light, like sunlight, are called photochemical reactions. These processes can occur naturally or under controlled condit..
