Abstract
About this talk
Bangladesh is an overpopulated country with a population density of greater than 1200/km2; and current ranking is 8th in the world. To feed the continuously increasing mouths there’s a big challenge ahead to create employment; thus, more industrialization is under process. The main aim of this seminar was to create public awareness on air pollution & it’s effects, help the community to save people from different complex diseases, including tuberculosis, asthma, bronchitis and other skin diseases and to improve our own health. Origin of pollution were found as air, water, sound and soil. Causes of air pollution were natural (dust and smoke) and manmade (burning of fossil fuels, agricultural activities, exhaust from factories industries and indoor air pollution). Main pollutants were seen as CO, SO2, NO2, O3 and particulate matter. Smog, Greenhouse effect, Accidental, industrial and transport are the five types of air pollution. Human effects of air pollution were found as- asthma attacks, reduced lung function, pulmonary cancer, coughing, pneumonia and bronchitis on the other hand environmental effects were global warming, acid rain, eutrophication, effect on wildlife, depletion of ozone layer. Vehicles were found to contribute major source of air pollution (over 40%) which creates NOx gases. Some key solutions to reduce air pollution was using public transportation, applying reduce-reuse-recycle theory, utilizing clean energy resource, walking, introducing hybrid vehicles, filtering smoke before releasing into the atmosphere by the industries. Banning old vehicles, relocation of
industries away from main cities, afforestation, using green technology, public awareness on pollution, law enforcement, emphasis on research works were prime recommended points to keep a clean environment.
Take Away Notes:
• Preventing different sorts of air pollution
• Being aware of air pollution and its and health related issues
• Possible solution and recommendation of minimizing air pollution and keeping a healthy environment
