Answer 1

Answer:

Air Pollution, Water Pollution and Noise Pollution!

Air Pollution, Water Pollution and Noise Pollution!The dictionary definition of pollution is to make air, water, soil, etc. dangerously dirty and not suitable for people to use. The main forms of pollution are air, water, soil, noise thermal and radioactive waves.

Air Pollution, Water Pollution and Noise Pollution!The dictionary definition of pollution is to make air, water, soil, etc. dangerously dirty and not suitable for people to use. The main forms of pollution are air, water, soil, noise thermal and radioactive waves.It is a man-made problem mainly caused by human waste material, release of poisonous gases and other chemical pollutants from the industry, agricultural pollutants like pesticides, and chemical fertilizers, pollutants by automobiles and dumping of chemical and nuclear wastes, etc. It has led to a worldwide environmental crisis. In many ways, it has changed both the individual and social ways of life.

Answer 2

Answer:

• The major sources of water pollution are domestic effluents, agricultural effluents, sewage disposal, industrial wastes, radioactive wastes and oil leakages, etc. ADVERTISEMENTS: All the Indian rivers, including the holy river Ganga, have become highly polluted today.
• The source of outdoor noise worldwide is mainly caused by machines, transport, and propagation systems. Poor urban planning may give rise to noise disintegration or pollution, side-by-side industrial and residential buildings can result in noise pollution in the residential areas.
• Land pollution is the degradation of the earth's surface as a result of human activity and waste. Some common examples include soil erosion or drastically changed climate patterns, particularly where it concerns agriculture.
• Several approaches to soil contamination monitoring include chemical, geophysical, and biological techniques. Chemical techniques are used to measure specific organic, inorganic, or radioactive contaminants in the soil using instruments such as a gas chromatograph, atomic absorption spectrometer, or mass spectrometer.
• The most common instruments used for measuring noise are the sound level meter (SLM), the integrating sound level meter (ISLM), and the noise dosimeter.
