air pollution is the introduction into the atmosphere of chemicals, particulates, or biological materials that cause discomfort, disease, or death to humans, damage other living organisms such as food crops, or damage the natural environment or built environment. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth’s ecosystems.
Indoor air pollution (see Airlog) and urban air quality are listed as two of the World’s Worst Toxic Pollution Problems in the 2008 Blacksmith Institute World’s Worst Polluted Places report. Air pollution control procedures are increasingly an important part of civic administration, although their goals are far from easy to achieve. It is also noticeable that although many urban concentrations of primary pollutants, for example, smoke and sulfur dioxide, are on the decline in developed countries, this is not always true in developing countries.
Here the desire for rapid industrial growth has often lowered urban air quality. Secondary air pollutants are generally proving a more difficult problem to eliminate than primary pollutants like smoke. solid waste Answers must be provided about what measures are being taken to resolve this problem of solid waste in our environment. * slide 1 of 13 Solid waste is a collective term used to distinguish non-biodegradable materials and discards that come from sources like: * Households * Businesses and Commercial establishments Manufacturers or Industrial sites * Biomedical sources like hospital and clinics. They are the trash collected by the municipal waste management units for segregation according to the process of disposal. Solid wastes are generally composed of non-biodegradable and non-compostable biodegradable materials. The latter refer to solid wastes whose bio deterioration is not complete; in the sense that the enzymes of microbial communities that feed on its residues cannot cause its disappearance or conversion into another compound.
Urban problems are pollution, (air, water, soil) rapid population growth, growing poverty, political impact of problems and unequal distribution of wealth. Some cities are trying to get rid of these problems by doing projects. Lima, Peru for example, has a self-help housing co-op where people were given a desert area to live on. They slowly developed roads, water, electricity, homes, trees, and ...
Parts of liquid waste materials are also considered as solid wastes, where the dredging of liquid wastes will leave solid sedimentation, to which proper waste management techniques should also be applied. * slide 2 of 13 What Is Pollution Caused by Solid Waste? Solid waste pollution is when the environment is filled with non-biodegradable and non-compostable biodegradable wastes that are capable of emitting greenhouse gases, toxic fumes, and particulate matters as they accumulate in open landfills.
These wastes are also capable of leaching organic or chemical compositions to contaminate the ground where such wastes lay in accumulation. Solid wastes carelessly thrown in streets, highways, and alleyways can cause pollution when they are carried off by rainwater run-offs or by flood water to the water pollution Chemical pollution of surface water can create health risks, because such waterways are often used directly as drinking water sources or connected with shallow wells used for drinking water.
In addition, waterways have important roles for washing and cleaning, for fishing and fish farming, and for recreation. Another major source of drinking water is groundwater, which often has low concentrations of pathogens because the water is filtered during its transit through underground layers of sand, clay, or rocks. However, toxic chemicals such as arsenic and fluoride can be dissolved from the soil or rock layers into groundwater.
... letting the solids dry. (Johnson, 1991, pp. 68-82) Another large contributor to water pollution is industrial runoff. Industrial pollution has been ... up dying. Besides the chemical contamination on the farm there are major problems with animal wastes. (Jones, 1993, pp. 39-60) ... should be located down slope from wells and never sited on floodplains. Lagoon should be constructed with a low-permeability ...
Direct contamination can also occur from badly designed hazardous waste sites or from industrial sites. In the United States in the 1980s, the government set in motion the Superfund Program, a major investigation and cleanup program to deal with such sites (U. S. Environmental Protection Agency 2000).
Coastal pollution of seawater may give rise to health hazards because of local contamination of fish or shellfish—for instance, the mercury contamination of fish in the infamous Minamata disease outbreak in Japan in 1956 (WHO 1976).
Seawater pollution with persistent chemicals, such as polychlorinated biphenyls (PCBs) and dioxins, can also be a significant health hazard even at extremely low concentrations (Yassi and others 2001).
Based on my observation here in our country maybe the result of our water pollution is our waste that we throw in different place that we can see in lake, sea and etc. that causes flood by simply throwing our waste in such different place that blocks our passage of water irrigation.
