Land pollution

Pollutants are assumed to have originated from agricultural fields and to have reached a river attached to suspensa eroded from a watershed. Like the, others, land pollution has also serious conse-, quences on both humans, animals and other living, organisms, and environment. Causes of Land Pollution 1.

NCBI Bookshelf. Disease Control Priorities in Developing Countries. Environmental pollution has many facets, and the resultant health risks include diseases in almost all organ systems. Thus, a chapter on air and water pollution control links with chapters on, for instance, diarrheal diseases chapter 19 , respiratory diseases in children and adults chapters 25 and 35 , cancers chapter 29 , neurological disorders chapter 32 , and cardiovascular disease chapter 33 , as well as with a number of chapters dealing with health care issues. Each pollutant has its own health risk profile, which makes summarizing all relevant information into a short chapter difficult. Nevertheless, public health practitioners and decision makers in developing countries need to be aware of the potential health risks caused by air and water pollution and to know where to find the more detailed information required to handle a specific situation.

This is because we can see the effects caused by the pollutants and their extent very clearly. It is normal human psychology to believe in what you see firsthand. Our land, on the other hand, is living a nightmare too. Land Pollution has emerged to become one of the serious concerns that we collectively battle. Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it is the only thing that ever has.

Soil contamination

Land pollution , the deposition of solid or liquid waste materials on land or underground in a manner that can contaminate the soil and groundwater , threaten public health , and cause unsightly conditions and nuisances. MSW includes nonhazardous garbage, rubbish, and trash from homes, institutions e. Garbage contains moist and decomposable biodegradable food wastes e. Hazardous wastes include harmful and dangerous substances generated primarily as liquids but also as solids, sludges, or gases by various chemical manufacturing companies, petroleum refineries , paper mills, smelters, machine shops, dry cleaners , automobile repair shops, and many other industries or commercial facilities. The permeability of soil formations underlying a waste-disposal site is of great importance with regard to land pollution.

Soil contamination or soil pollution as part of land degradation is caused by the presence of xenobiotics human-made chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons , polynuclear aromatic hydrocarbons such as naphthalene and benzo a pyrene , solvents , pesticides, lead , and other heavy metals. Contamination is correlated with the degree of industrialization and intensity of chemical substance. The concern over soil contamination stems primarily from health risks, from direct contact with the contaminated soil, vapours from the contaminants, or from secondary contamination of water supplies within and underlying the soil. In North America and Western Europe the extent of contaminated land is best known, with many of countries in these areas having a legal framework to identify and deal with this environmental problem. Developing countries tend to be less tightly regulated despite some of them having undergone significant industrialization.

Environmental and Health Impacts of Air Pollution: A Review

The soil in which our fruit and vegetables grow is also suffering its consequences, the effects of which getting to us directly, for instance, through the aforementioned foodstuffs.

Коммандер относился к этой программе с религиозным трепетом, но использовал ее не в политических целях: она служила ему для расчета времени, оценки информации и схематического отображения ситуации, выработки сложных стратегических решений и своевременного выявления слабых мест.
