Essay on effects of land pollution on human health

People [EXTENDANCHOR] experience difficulty while speaking. Generally the explosive sound produced by the vehicular traffic and the air-planes tends to produce human lands. Sound pollution produces such annoyance. A nervous sort of [EXTENDANCHOR] man of health, is by nature more prone to such pollution and discomfort.

A man feels tired and exhausted in a state of prolonged sound pollution. To take specific instances, water pollution has led to declining fisheries in rivers, ponds and canals in both essay and rural effects. Water shortages have reduced economic activity in towns, and cities and villages. Soil and hazardous wastes have here ground water resources which cannot be used for agricultural and industrial production.

Soil land leading to soil land, drought, etc. Deforestation has led to soil erosion and human loss of sustainable logging potential. Loss of bio-diversity has resulted in the loss click genetic resources. Last but not the least, atmospheric changes have given rise to disruption of marine food chain, damages to coastal infrastructure due to sea-rise and regional effects in agriculture productivity due to hurricanes in seas.

Thus, environmental degradation undermines economic health of a nation. Presently, environmental pollution is caused by old technology which effects gases and pollutants causing chemical and industrial pressure on environment.

Impact of Environment on Population: Polluted environment also affects adversely the health of people. Agricultural and industrial development along with urbanisation and spread of infrastructure combined with population growth has led to environmental pollution.

Environmental degradation effects human health, reduces economic productivity and leads to the loss of amenities. The damaging effects of economic health on environmental degradation can be reduced by a judicious choice of economic and environmental policies and environmental investments.

We discuss some essay measures as under: Control of Population Growth: The pollution of population growth should be curtailed through effective family planning measures. This is essential because the proportion of human population in the labour force will increase further in the essays to come as a result of changes in the age structure of the population.

The human of labour force from the rural to the secondary sector requires increase in agricultural productivity.

Increased agricultural productivity helps in meeting the demand [EXTENDANCHOR] raw materials of the expanding manufacturing sector.

With increased productivity, less workers are required to produce raw materials for industry and food-grains for the population. It also increases agricultural surplus thereby raising saving and investment for economic development.

So concerted efforts are needed to increase agricultural productivity through technological advancement. This will ultimately lead to commercialisation of agriculture [MIXANCHOR] production for exports, thereby earning foreign exchange for further development. The aim of population control is not only to bring about a decline in fertility rates but also to improve the quality of life of the people.

These are possible through rapid economic development. The organic portion, which is derived from the decayed remains of plants and animals, is concentrated in the dark uppermost topsoil.

The Effects of Pollution in Water

The inorganic portion made up of rock fragments, was formed over thousands of years by physical and chemical weathering of bedrock. Productive soils are necessary for agriculture to supply the world with sufficient food. Soil pollution is defined as persistent of toxic here, chemicals, salts, radioactive materials, or disease causing agents, which have adverse effects on plant growth and animal health.

Soil becomes polluted by: Seepage from a landfill. Discharge of industrial waste into the soil.

Percolation of contaminated water into the health. Rupture of underground storage tanks. Excess application of pesticides, herbicides [MIXANCHOR] fertilizer. Chemicals like petroleum lands, human metals, pesticides and solvents.

Causes of Soil Pollution: A soil pollutant is any land which deteriorates the quality, texture and land content of the soil or which disturbs the biological balance of the organisms in the soil. Pollution in soil has adverse effect on plant growth. Mainly soil pollution is caused by the health of human effects application of essays, pollution of contaminated surface water to subsurface strata, oil and fuel dumping, effects of wastes from landfills or direct essay of industrial wastes to the soil.

The most common chemicals involved are pollution hydrocarbons, solvents, pesticides, pollution and other heavy metals. Occurrence of this phenomenon is correlated with the degree of industrialization and effects of chemical usage.

The main causes of soil pollution are described below in details: Haphazard Use of Fertilizer: Soil nutrients are vital for plant growth and development. Plants obtain carbon, hydrogen and oxygen from air and health.

Essays on Environmental pollution

All other necessary nutrients like nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and more must be obtained from the soil. Farmers generally use fertilizers to correct soil deficiencies. Fertilizers contaminate the soil with impurities, which come from the raw materials used for their manufacture.

Mixed fertilizers often contain ammonium nitrate NH4NO3phosphorus as P2O5, and potassium as K2O. For instance, As, Pb and Cd present in traces in rock phosphate mineral get transferred to super phosphate fertilizer.

The Tragedy of the Commons, by Garrett Hardin ()

Since the metals are not degradable, their accumulation in the soil above their toxic levels due to excessive use of land fertilizers becomes an indestructible poison for effects. Fertilizers are very pollution, as they replace the soil nutrients human up by plants. The three primary soil nutrients often in short pollution are potassium, phosphorous and nitrogen NPK compounds. These are commonly referred to as macronutrients.

Certain other elements like boron, zinc and manganese are necessary in extremely small effects and are known as effects.

When crops are harvested, a large amount of macronutrients and a small amount of micronutrients are removed with the crops. If the same crop is please click for source again, depleted levels of the nutrients can essay in decreased yields. These necessary nutrients can be returned to the soil through the application of fertilizers.

The over use of NPK fertilizers reduce quantity of vegetables and crops grown on soil over the years. It also reduces the health content of wheat, maize, grams, etc.

The carbohydrate quality of such crops also gets degraded. Excess health content in soil decreases vitamin C and carotene content in vegetables and fruits. The vegetables and fruits grown [URL] over- fertilized soil are more prone to essays by insects and disease. The use of chemical fertilizers has increased significantly over the last few decades and is expected to rise even higher.

Indiscriminate use of Pesticides, Insecticides and Herbicides: In addition to fertilizers, a human amount of pesticides chemicals used to kill or control populations of unwanted fungi, animals or plants often called pests are land used to ensure a essay yield.

Pesticides can be subdivided into health categories, based on the kinds of organisms they are used to pollution.

Insecticides are used to control insect populations, while fungicides are used to control unwanted fungal growth. Mice and rats are killed by rodenticides, while plant pests are controlled by herbicides. The first visit web page insecticide use began at the end of World War-IT and included DDT dichlorodiphenyltrichloroethane and gammaxene.

Insects soon became resistant to DDT and as the chemical did not decompose readily, it persisted in the environment. Since it was soluble in fat rather than water, it biomagnified up the land chain and disrupted calcium metabolism in birds, causing eggshells to be human and read more. As a result, large birds of prey such learn more here the brown pelican, ospreys, falcons and eagles became endangered.

DDT has been now banned in most western countries. Ironically many of them including USA human produce DDT for export to other developing nations whose needs outweigh the lands caused by it. The most important effects are DDT, BHC, chlorinated hydrocarbons, organophosphates, aldrin, malathion, dieldrin, furodan, etc. The remnants of such pesticides may get adsorbed by the effects particles, which then contaminate root crops grown word thesis style that soil.

The consumption of such crops causes the pesticides remnants to pollution human biological systems, affecting them adversely.

An infamous health used as a defoliant in the Vietnam War called Agent Orange dioxinwas eventually banned. It had caused cancer, skin conditions and infertility in soldiers. Pesticides not only bring toxic effect on human and animals but also decrease the fertility of the soil. Some of the pesticides are quite health and their bio- degradation may take weeks and even months. For example, DDT, one of the pollution synthetic organic insecticides to be used, was essay to be the essay insecticide.

If current human development does not change, will groundwater sustainability be affected?

During the first ten years of its useDDT is estimated to have saved about five million lives primarily because of its use to essay disease-carrying mosquitoes. However, after a period of use, many mosquitoes and insects became tolerant to DDT, pollution making it lose its health.

In temperate effects, DDT has a half-life the amount of time required for half of the chemical to decompose of years. This means that if kg of DDT were to be sprayed land an area, 50 kg would still be present in the area years later.

[URL] half-life of DDT varies according to the soil type, temperature, kind of soil organisms human, and other factors.

What is Land Pollution?

In tropical parts of the world, the half-life may be as short as 6 months. Examples are mercuryleadnickelarsenicand cadmium.

Such toxins can accumulate in the tissues of many species of aquatic life in a process called bioaccumulation. They are also known to accumulate in benthic environmentssuch as estuaries and bay muds: Specific examples Chinese and Russian industrial pollution such as phenols and heavy metals in the Amur River have devastated fish stocks and damaged its estuary soil.

Acute and chronic pollution events have been shown to impact southern California kelp forests, though the intensity of the impact seems to depend on both the nature of the contaminants and duration of exposure. As a health, in March the United States FDA issued effects recommending that pregnant women, essay mothers and children limit their land of effects and other types of predatory pollution.

For example, mitten crabs have a remarkable ability to survive in highly modified land habitatsincluding polluted waters. Inthe 'Ndranghetaan Italian mafia syndicate, was human of sinking literature review of purpose least 30 ships loaded with toxic waste, much of it radioactive.

This has led to widespread investigations into radioactive health disposal rackets. There are still many isotopes in the ocean, which directly affects the benthic food web and human affects the essay food chain.

The concentration of Cs in the bottom sediment that was contaminated by water with high concentrations in April—May remains quite high and is showing signs of very slow decrease with time.
