The stark difference in emissions of nitrogen oxides NOx is due to the much stricter testing applied to large vehicles in the EU, according to the researchers behind a new report. They say the same strict measures must be applied to cars.
Pollution started from prehistoric timeswhen man created the first fires. According to a article in the journal Science, " soot " found on ceilings of prehistoric caves provides ample evidence of the high levels of pollution that was associated with inadequate ventilation of open fires.
Core samples of glaciers in Greenland indicate increases in pollution associated with Greek, Roman, and Chinese metal production. The Industrial Revolution brought an infusion of untreated chemicals and wastes into local streams that served as the water supply.
King Edward I of England banned the burning of sea-coal by proclamation in London inafter its smoke became a problem;   the fuel was so common in England that this earliest of names for it was acquired because it could be carted away from some shores by the wheelbarrow.
It was the industrial revolution that gave birth to environmental pollution as we know it today. London also recorded one of the earlier extreme cases of water quality problems with the Great Stink on the Thames ofwhich led to construction of the London sewerage system soon afterward.
Pollution issues escalated as population growth far exceeded viability of neighborhoods to handle their waste problem. Reformers began to demand sewer systems and clean water.
August Bebel recalled conditions before a modern sewer system was built in the late s: There were no public toilets in the streets or squares. Visitors, especially women, often became desperate when nature called. In the public buildings the sanitary facilities were unbelievably primitive As a metropolis, Berlin did not emerge from a state of barbarism into civilization until after A British expert in concluded that Berlin represented "the most complete application of science, order and method of public life," adding "it is a marvel of civic administration, the most modern and most perfectly organized city that there is.
Chicago and Cincinnati were the first two American cities to enact laws ensuring cleaner air in Pollution became a major issue in the United States in the early twentieth century, as progressive reformers took issue with air pollution caused by coal burning, water pollution caused by bad sanitation, and street pollution caused by the 3 million horses who worked in American cities ingenerating large quantities of urine and manure.
As historian Martin Melosi notes, The generation that first saw automobiles replacing the horses saw cars as "miracles of cleanliness. Extreme smog events were experienced by the cities of Los Angeles and Donora, Pennsylvania in the late s, serving as another public reminder. Awareness of atmospheric pollution spread widely after World War II, with fears triggered by reports of radioactive fallout from atomic warfare and testing.
National news stories in the late s—especially the long-term dioxin contamination at Love Canal starting in and uncontrolled dumping in Valley of the Drums —led to the Superfund legislation of The development of nuclear science introduced radioactive contaminationwhich can remain lethally radioactive for hundreds of thousands of years.
Lake Karachay —named by the Worldwatch Institute as the "most polluted spot" on earth—served as a disposal site for the Soviet Union throughout the s and s. ChelyabinskRussia, is considered the "Most polluted place on the planet". The toll on the worst-affected populations and the growth since then in understanding about the critical threat to human health posed by radioactivity has also been a prohibitive complication associated with nuclear power.
Though extreme care is practiced in that industry, the potential for disaster suggested by incidents such as those at Three Mile Island and Chernobyl pose a lingering specter of public mistrust. Worldwide publicity has been intense on those disasters. The borderless nature of atmosphere and oceans inevitably resulted in the implication of pollution on a planetary level with the issue of global warming.Research programme in Sweden.
Rising fuel prices and global warming have resulted in renewed interest in firewood as a direct fuel. Dozens of amateur engineers around the world have converted standard production cars into producer gas vehicles, with most of these modern woodmobiles being built in Scandinavia.
Chest pain, congestion, throat inflammation, cardiovascular disease, respiratory disease are some of diseases that can be causes by air pollution. Water pollution occurs due to contamination of water and may pose skin related problems including skin irritations and rashes.
Public Health Issues: The current environmental problems pose a lot of risk to health of humans, and animals. Dirty water is the biggest health risk of the world and poses threat to the quality of life and public health.
Run-off to rivers carries along toxins, chemicals and disease carrying organisms. Discover the risks of air pollution in Thailand.
I use realtime reports & reliable studies to show the cleanest & dirtiest areas to live in. According to the United States Environmental Protection Agency, driving a car is the single most polluting thing that most of us do. This is not a new problem. In the . Not only do cars produce a large portion of the world's pollution, in excess of several billion tons per year in the United States alone, but boats, trucks, trains and buses also contribute to the pollution whole.
