Most of the water pollution-intensive industries are in National Capital Region‚ Calabarzon‚ and Region III. Food manufacturing industries‚ piggeries‚ and slaughterhouses are the main sources of organic pollution (PEM‚ 2004). A report from a study conducted by the United Nations Industrial Development Organization (UNIDO) in 1999 emphasizes that the situation is

Air pollution in India is a serious issue with the major sources being fuelwood and biomass burning‚ fuel adulteration‚ vehicle emission and traffic congestion.[1][2] India has a low per capita emissions of greenhouse gases but the country as a whole is the third largest after China and the United States.[3] A 2013 study on non-smokers has found that Indians have 30% lower lung function compared to Europeans.[4] The Air (Prevention and Control of Pollution) Act was passed in 1981 to regulate air

What are the different types of air pollution? How does each of these types of air pollution affect human health and the environment? What some ways to control air pollution? Industrial smog is the black-brown colored haze that is in the air that can be seen over some cities. It is mostly visible in the summer. Burning coal produces sulfur dioxide (SO2) that eventually ends up into our atmosphere. Photochemical Smog is air pollution containing ozone and other reactive chemical compounds formed

availability of fresh water and its unequal distribution make water pollution a matter of great concern. Water pollution is generally localized and confined‚ making it more severe. The pollutants undergo many reactions and can become hazardous. 70 % of India’s fresh water is polluted‚ including several high altitude lakes. While water pollution is easier to study and manage‚ its control is highly complex and very costly. Water pollution is defined as presence of any foreign substance (organic‚ inorganic

Noise Pollution Noise pollution is not a necessary price to pay for living in an industrial society. Much can be done to reduce the severity of the problem. For example‚ vehicles and other machines can be built to produce less noise. Four-cycle engines can replace much noisier two-cycle engines in such products as lawnmowers‚ motorboats‚ and jet skis. Labels that indicate the noise levels of appliances and tools can help consumers avoid noisy products and choose quieter alternatives. Even

The usage of old transports is ruining the situation. No prevailing laws are strictly implemented‚ as a result‚ factories exude their smoke into the air. Simultaneously‚ wasted poisonous substances are excreted in the water of rivers and lakes which is causing water pollution. The conditions exacerbate in the
