Write a report on air pollution

Pollution A pollutant is any substance that, when in an environment, poisons our air, land and water. Chemicals have poisoned all of the world, harming humans, wildlife, and plant life, on land, sea and air.

Approximatelysynthetic chemicals are write a report on air pollution on the market, with one thousand new chemicals are added yearly. Although companies test the toxicity of their products individually, they do not exist alone in the environment.

Compounds are altered in combination with others, but the effect of these combinations are not tested or studied.

Pesticides, designed to kill insects, weeds and fungus, are also toxic to human nervous systems, and are linked to cancer and reproductive, developmental, neurological and immune-system damage. Every chemical we use, every substance we produce, in manufacturing, farming, energy use, or consumption, remains here on Earth.

These poisons may seem to disappear—but they are only hidden. The World Health Organization reports that 3 million people now die each year from the effects of air pollution.

This is three times the 1 million who die each year in automobile accidents. In thetraffic fatalities total just over 40, per year, while air pollution claims 70, lives annually. Bernie Fischlowitz-Roberts September 17, Point source pollution comes from a particular place such as industrial and sewage treatment plants.

In the last 25 years, the United Stateshas made considerable progress in cleaning-up this cause of pollution.

Non-Point source pollution occurs when rainfall or snow melt moving over and through the ground, picks up natural and human-made pollutants and finally deposits them into lakes, rivers, wetlands, coastal waters, and even our underground sources of drinking water.

These non-point source pollutons include: Fertilizers, herbicides, and insecticides from agricultural lands and residential areas; Oil, grease, toxic chemicals and heavy metals from urban runoff and energy production; Sediment from improperly managed construction sites, crop and forest lands, and eroding stream banks; Salt from irrigation practices and acid drainage from abandoned mines; Bacteria and nutrients from livestock, pet wastes, and faulty septic systems; Agriculture, forestry, grazing, septic systems, recreational boating, urban runoff, construction, physical changes to stream channels, and habitat degradation, careless or uninformed household management.

The latest National Water Quality Inventory indicates that agriculture is the leading contributor to water quality impairments, and responsible for degrading 60 percent of the impaired river miles and half of the impaired lake acreage surveyed by states, territories, and tribes.

Runoff from urban areas is the largest source of water quality impairments to surveyed estuaries. Worldwatch Magazine Jan-Febp.

Endocrine Disruptors The threat of toxic substances has been misunderstood.

Air (Pollution and Control of Pollunion) Rules,

Scientists had assumed that, if they could rule out cancer, then people would be protected from everything else as well. But a new threat has been discovered. Until recently, research on and regulation of synthetic chemicals and pollution focused on the dangers of genetic mutation, gross birth defects, and especially, cancer.

A decade ago, it was assumed that if very high-dose testing was used, the probability of causing cancer would not be missed. Wildlife studies and laboratory experiments provide solid evidence that synthetic chemicals have contributed to dwindling wildlife populations by disrupting hormones, altering sexual development, impairing reproduction, and undermining the immune system.

Endocrine systems control body growth, organ development, metabolism and regular body processes such as kidney function, body temperature and calcium regulation. Endocrine disruptors include any chemical that interferes with hormones such as thyroid, cortisol, insulin or growth regulators.

These chemicals are being tested for potential links to prostate, testicular and breast cancers, as well as lowered sperm counts and behavioral and learning abnormalities. Theo Colborn and coauthors Dianne Dumanoski and Dr. John Peterson Myers, demonstrates that many man-made chemicals interfere with the body's hormones.

Contaminants can also transfer to the fetus where chemicals interfere with the hormonal signals directing fetal development. The effects may not appear until puberty or later. Some of these chemicals alter sexual development, some undermine intelligence and behavior, others make our bodies less resistant to disease.

Fetal development is extremely sensitive to any variations in hormone signals. For a fetus to grow up according to its genetic blueprint, the right hormone message has to arrive at the right place in the right amount at the right time.

These chemicals interfere with the delivery of that message. Hormonally active chemicals can do damage at extremely low exposure levels, because these compounds do not behave according to the classic linear dose-response model that is, the higher the dose, the greater the harm that traditional toxicology assumes.

Genetically Engineered Food is a Form of Pollution Genetic engineering refers to a technology where scientists transfer genes from one species to another. This practice goes far beyond selective breeding or hybridization.

For example, scientists have spliced genes from viruses, bacteria and animals into food crops. Presently, two thirds of processed foods are made with a genetically engineered organism.Studybay is an academic writing service for students: essays, term papers, dissertations and much more!

A year tradition of excellence is extended in the Fourth Edition of this highly regarded text. In clear. Air pollution is a general term that covers a broad range of contaminants in the atmosphere. Pollution can occur from natural causes or from human activities. Apr 18,  · The annual State of Global Air Report was published on Tuesday by the Health Effects Institute and it found that over 95 percent of the world's population is breathing unhealthy air while long.
