Their study proposed using the life quality index as a tool for quantifying the level of public expenditure beyond which the use of resources is not justified. The enactment of strict rules and laws can help prevent this pollution. Pollution control is therefore an important component of disease control, and health professionals and authorities need to develop partnerships with other sectors to identify and implement priority interventions.

Air The broadest analysis of the implementation of control strategies for air pollution was conducted by the U. The recalculated figure is still well above the fifth percentile estimate of benefits and does not undermine the positive cost-benefit ratio reported.
International collaboration involving both governmental and nongovernmental organizations can guide this highly interdisciplinary and intersectoral area of disease control. It is caused by machines in industries, loud music, etc. Every other day new industries are being set up, new vehicles come on roads and trees are cut to make way for new homes.
The developing countries need to avoid the experiences of water pollution and associated disease outbreaks in industrial countries.
The most famous disease outbreak of this type occurred in London in U. Pollution of river waters can lead to hazardous risks to humans, animals and also plants.
Another topic is to assess the health issue pertaining to greenhouse gases and climate change, which are related to the same sources as urban air pollution Intergovernmental Panel on Climate Change The enactment of strict rules and laws can help prevent this pollution. The existing literature indicates that long-term exposure may have more adverse health effects than short-term exposure and, hence, have higher cost implications.
This success in disinfecting water supplies has contributed significantly to public health by reducing the transmission of waterborne disease. A common example is the leaching out of nitrogen compounds from fertilized agricultural lands.
Technologies to reduce pollution at its source are plentiful, as are technologies that reduce pollution by filtering it away from the emission source end-of-pipe solutions; see, for example, Gwilliam, Kojima, and Johnson Fecal sludge collected from pit latrines is dumped into a river at the Korogocho slum in NairobiKenya.
In addition, the sugarcane rinse liquid may contain pesticide residues. Leather tanneries produce a significant amount of solid waste, including hide, hair, and sludge.
WastewaterSewageand Industrial wastewater The specific contaminants leading to pollution in water include a wide spectrum of chemicalspathogensand physical changes such as elevated temperature and discoloration.
Plants may not be able to grow properly. WHO concludes that 0. Marine pollution A polluted river draining an abandoned copper mine on Anglesey One common path of entry by contaminants to the sea are rivers. We do not consider agents whose exposure depends on lifestyle, such as solar radiation and food additives, nor agents occurring in the environment as a consequence of accidents or warfare.
Lead exposure has been implicated in hypertension in adults, and this effect may be the most important for the lead burden of disease at a population level WHO Aunan and others assessed the costs and benefits of implementing an energy saving and air pollution control program in Hungary. Water-borne diseases like cholera, diarrhoea have also increased in all places.
Air Pollution Air pollutants are usually classified into suspended particulate matter PM dusts, fumes, mists, and smokes ; gaseous pollutants gases and vapors ; and odors. Exposure to Air Pollutants The extent of the health effects of air pollution depends on actual exposure.
Pollution disturbs our ecosystem and the balance in the environment. We should be addressing the cause of the problem, i. This occurs when there is leakage of sewage water and mixing with that of pure water supplied by municipal water pipes. Analysis of groundwater contamination may focus on soil characteristics and site geology, hydrogeologyhydrologyand the nature of the contaminants.
The assessment of non-occupational exposure to asbestos presents difficulties, since levels are generally low, and the duration and frequency of exposure and the type of fibre are seldom known with precision. Since this water directly enters the body, it decides the quality of health.
They estimated the cost-benefit ratio at 1 to 3. Contamination during rains due to the flow of rainwater from contaminated land into rivers. Water flowing out of dams: All the waste is flowed out into rivers. It occurs due to several factors; the industrial wastes dumped into the rivers and other water bodies cause an imbalance in the water leading to its severe contamination and death of aquatic species.
This has to be taken as an individual responsibility by all. The analysis developed a hypothetical scenario for toassuming that the real costs for pollution control during this period could be compared with the benefits of reduced mortality and morbidity and avoided damage to agricultural crops brought about by the reduction of major air pollutant levels across the country during this period.
Their results tend to show an increased risk in the categories at highest exposure, with relative risks in the range 1.An analysis of the factors that cause water pollution.

Other causes of water pollution. Apart from the industrial causes of water pollution, as we saw on the previous page, here are some more: Sewage and waste water Every day, we cook, do laundry, flush the toilet, wash our cars, shower and do many things that use water.
Think about how we use water in schools, hospitals and public places. An analysis of the factors that cause water pollution.

As eye-opening as "Blackfish" and as inspiring as "An Inconvenient Truth". Accidental water pollution can arise from many sources (such as burst pipes and tanks, major leaks, fires and oil spills) and can cause varying degrees of damage, depending on the quantity, toxicity and persistence of the pollutant, and the size and adaptability of the water body.
Water pollution has many different causes and this is one of the reasons why it is such a difficult problem to solve. Sewage.
With billions of people on the planet, disposing of sewage waste is a major problem. so if they cause pollution they themselves are the first people to suffer. Ultimately, the polluter pays principle is designed to.
The causes of water pollution include a wide range of chemicals and pathogens as well as physical parameters. Contaminants may include organic and inorganic substances. Elevated temperatures can also lead to polluted water.Download
