Experiment to estimate bacterial composition of the air by standard plate count (SPC) method: The best answers are voted up and rise to the top. - Quiz & Self-Assessment Test, Should I Major in Environmental Science? In this experiment, we will examine air pollution in our own environment by trapping the airborne particles and examining them under a microscope. Air pollution, a by-product of economic growth, has been incurring extensive environmental costs in Seoul, Korea. Outdoor air pollution has become a cause for alarm in India in particular because recent data suggest that ambient pollution levels in Indian cities are some of the highest in the world.

You can test out of the You can do a simple study to determine some of the factors that affect air pollution. Cover the petri-dishes immediately and allow the medium to solidify. These particles then react with other chemicals in the air to form even smaller, secondary particulate matter. Experiment to measure dust fall in any specified area: Requirements: Dust fall trappers, distilled water, physical balance, sieve, scale. Were your hypotheses supported or not?
