Here is your essay on Methods used to Control Air Pollution !Most kinds of air pollutions can be controlled by modern technology, but the costs ultimately be borne by the public in the form of higher prices for manufactured goods, higher taxes, redu­ced profit margins in industry, and more restrictions on individual activities such as burning leaves and trash and use of automobiles. The benefits involve not only improved environmental quality, but improved health, improved agriculture and plant growth, and reduced deterioration of material goods. image source: climate.america.gov ADVERTISEMENTS: In USA, various devices such as the positive crankcase venti­lation valve and catalytic converter have been developed to reduce exhaust emissions by automobiles, but these devices are not always fully maintained by the public.Likewise, particulate pollution from industry and power generation…
