Answers
Answer:
smoke directly mixes with the atmosphere, disturbing the balance between the constitution of air. this is called air pollution.
ex. 1) factory smoke
2) tobacco smoke
Answer:
Explanation:
• Determination of impact zone (through a screening model) and developing a monitoring network.
• Monitoring the existing status of ambient air quality within the impacted region (7-10 km from the periphery) of the proposed project site.
• Monitoring the site - specific meteorological data, viz wind speed and direction, humidity, ambient temperature and environmental lapse rate.
• Estimation of quantities of air emission including fugitive emission from the proposed project.
• Identification, quantification and evaluation of other potential emission (including those of vehicular traffic) within the impact / zone and estimation of cumulative of all the emission / impacts.
• Prediction of changes in the ambient air quality due to point, line and areas source emission through appropriate air quality models.
• Evaluation of the adequacy of the proposed pollution control devices to meet gaseous emission and ambient air quality standards.
• Delineation of mitigation measures at source, path ways and receptor.
The two air Pollutant are :-
1. Nitrogen dioxide.
2. Sulphur dioxide.
