Abstract:

Air is the most essential requirement for life on this planet and its pollution will certainly affect the life of plants, animals and human beings on this earth. If pollution will go on increasing unchecked, unnoticed and un-controlled, the time will come when it will become impossible to breathe fresh air as we do today. Air can be polluted by many ways e.g. Industrial pollution, biological pollution, pollution by Radiation etc. The rate of pollution in developing countries is higher than that of developed countries but we are a bit lucky because we have a history of long and bitter experience of developed countries which can help us in our environmental protection programmes and vie should seek help from their experiences. The present research work emphasizes on air pollution created by different gas and are welding processes at various welding workshops in Lahore. The air samples from welding workshops were collected by the air filtration through Glass Fibre filtration discs and were analysed by Atomic Spectrophotometric methods. The concentration of toxic gases was calculated by the direct reading instrument i.e. Drager's Tubes. It was found that almost in every case the concentration of toxic substances was greater than that of their threshold limit values. It is suggested to chalk out environmental protection programmes and to enforce the Environmental Pollution Control Act in its full form.
