Municipal sewage is considered to be the main pollutant of water. Ozone Waste Water Treatment: Ozone waste water treatment method is becoming very popular. With reference to water pollution through mercury, mention of Minimata Gulf incident must be made. Religious Malpractices: Another serious fact about this problem is the lifestyle of people that comprises of several malpractices involving dirtying the water, giving it the name of religion or rituals. Among hospitalized children in India, 13% deaths are caused by the acute respiratory infection.
Upon independence from Britain, India adopted a constitution and numerous British-enacted laws, without any specific constitutional provision on protecting the environment. There is a long history of study and debate about the interactions between population growth and the environment. The key requirement, for this to be true, is continued adoption of technology and scientific management of resources, continued increases in productivity in every economic sector, entrepreneurial innovation and economic expansion. India is the world's largest consumer of fuelwood, agricultural waste and biomass for energy purposes. Industrial Waste: Industrial waste contains pollutants like asbestos, lead, mercury and petrochemicals which are extremely harmful to both people and environment.
Animal waste: The waste produce produce by animals is washed away into the rivers when it rains. In 2000, India's Supreme Court directed all Indian cities to implement a comprehensive waste-management programme that would include household collection of segregated waste, recycling and composting. Religious practices also demand that offerings from a puja be immersed in a river. Decay and putrefaction of household wastes and dead bodies : With death of animals, certain anaerobic bacteria putrefy the dead body as a result of which ammonia and H 2S are produced giving foul smell. Food processing industries include dairies, breweries, distilleries, meat-packing, etc. Accidentals leakage may happen anytime and may cause damage to environment and result in.
There are many causes for water pollution but two general categories exist: direct and indirect contaminant sources. March 2009 Noise pollution or noise disturbance is the disturbing or excessive noise that may harm the activity or balance of human or animal life. The effects of water pollution are varied. These wastes contain harmful chemicals and toxins which make the water poisonous for aquatic animals and plants. In many areas of the world, aquatic weeds have multiplied explosively. Water needs to be preserved and respected today, for us to live a tomorrow.
Without taking a step backward in terms of our standards of living, the answer seems to lie in a combination of many small changes in our daily practices and paying more for goods and services, so that manufacturers of various materials and drivers of automobiles for instance will have cleaner devices with which to conduct their activities. People are investing in rain water harvesting projects to collect rainwater and preserve it in wells below ground level. Pollution caused by burning fuelwood and biomass is one of the main causes of the Asian brown cloud. Indoor noise can be caused by machines, building activities, and music performances, especially in some workplaces. Mining activities: Mining is the process of crushing the rock and extracting coal and other minerals from underground. Direct sources include effluent outfalls from factories, refineries, waste treatment plants etc. Some of the few solid waste landfills India has, near its major cities, are overflowing and poorly managed.
They discharge radioactive waste water into the sea, which with ocean currents then carry around the world. In our everyday lives, a great deal can be done to minimize pollution if we take care to recycle materials whose production creates pollution and if we act responsibly with household chemicals and their disposal. In the Black sea, an alien jellyfish called Mnemiopsis leidyi reduced fish stocks by 90% after arriving in ballast water. Mining operations can result in metals leaching into the acidic effluents, thus adding to the metal load in rivers, lakes and groundwater. Thermal pollution is considered hazardous for the whole aquatic ecosystem. Fertilizers and pesticides used in agriculture in northwest have been found in rivers, lakes and ground water.
Additionally, many towns and cities located on the banks of major rivers even lack the basic wastewater and sewage treatment mechanisms. The maintenance of minimum flows, to sustain river ecology through its course as well as its confluences, is a recent awakening which requires serious thought. Dumping: Dumping of solid wastes and litters in water bodies causes huge problems. Even , theoretically controlled by stringent rules that require hospitals to operate incinerators, is routinely dumped with regular municipal garbage. List of Sources Which Contributes to Water Pollution 1. In the Yale Environmental Performance Index by the Yale University, India ranked at 174th position out of 178 countries on air pollution. Ozone oxidizes bacteria, molds, organic material and other pollutants in water.
Research in has uncovered a relationship between environmental quality, measured by ambient concentrations of air pollutants and per capita income. Nearly 80% of the water supplied for domestic use passes out as wastewater. Before we forget about the water pollution in the Ganga River, we should keep in mind that this problem is never going to go away unless we do something about it. Radioactive waste: is produced using nuclear fission or fusion. Polluted water can lead to diseases such as cholera, tuberculosis, dysentery, jaundice, diarrhoea, etc. Archived from on 12 December 2012. The farm animal wastes often pose serious problems of odour and water pollution.
When sewage enters a lake or stream, micro-organisms begin to decompose the organic materials. According to a report of the Ministry of Water Resources on the study of minimum flows in the Ganga, impact on river water quality resulting from discharges of treated or untreated wastewater into the river will depend on the dilution offered by the quantum of flows in the river. The problem is not only that India lacks sufficient treatment capacity but also that the sewage treatment plants that exist do not operate and are not maintained. Several billion salmon and herring eggs are also destroyed. The higher the concentration of dissolved oxygen, the better the water quality.
This has lead to the death of many both man and animals. The study further says that since the water is scarce it is not possible to add further fresh water for dilution. Discharge of mercury from gold mining activities has polluted some streams in Brazil and Ecuador and created serious health problems. Plastics : Plastic is far and away the most common substance that washes up with the waves. This has resulted in the drop of the major air pollutants during 1995-2008. With the cooperation of government, last 30 years Indian private firms or industries increased vastly. Significant industrial contributors of wastewater include paper mills, steel plants, textile and sugar factories.
