pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse change.[1] Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution.

A new study stresses the overlooked hazards that dumped pharmaceuticals found in wastewater pose to the world’s freshwater streams. So far, the impacts and consequences on water quality and aquatic life are unknown or under researched, and the authors hope their findings might warrant more work in this direction. Dr. Emma Rosi-Marshall, lead author of [...]
Based on a massive set of data collected from Houston by Rice University researchers, there is a direct correlation between out-of-hospital heart attacks and levels of air pollution and ozone. Rice statisticians Katherine Ensor and Loren Raun announced their findings today at the American Association for the Advancement of Science (AAAS) conference in Boston – [...]
A few days ago I was telling you about the drastic state of pollution taking place in China these days – pollution levels are so high that all newspapers, even communist ones started pressing the government into environmental protection. To see how much the Beijing pollution evolved – take a look at the picture of [...]
Canada’s oil production has been blooming lately, mostly due to the oil sands in Alberta, who hold some of the world’s largest oil reserves. However, a new study shows that exctractions from these oil sands are associated with an increase of local water toxicity. The black gold curse Researchers from the Queen’s University in Kingston, [...]
When you think of air pollution, inevitably your mind wanders to huge, fume spilling power stations, old motor trucks and other nasty things in these lines. Surprisingly enough, researchers at University of California, Riverside, found that charbroiled burgers, chicken, and steaks are behind much of Southern California’s air pollution, topping even diesel engines. These findings were made after [...]
Carnivorous plants may soon have to give up their meaty habits and turn veggie, as a recent study found that carnivours plants in Swedish bogs have significantly reduced their preying behavior, due to nitrogen pollution. The sundew drosera rotundifolia is one of the most common carnivours plant species, growing across much of Northern Europe in rain-fed bogs. [...]
Besides ever thinning ice, permafrost melting, soot deposits, habitat loss, you might as well add another significant factor threatening the arctic ecosystem – mercury. For some time, the alarmingly high mercury concentrations in the regions were rather unaccounted for, in part, however a new research by scientists at Harvard’s Atmospheric Chemistry Modeling Group suggests that [...]
According to a new report released by the Chinese authorities, global warming “threatens China’s march to prosperity by cutting crops, shrinking rivers and unleashing more droughts and floods“. China, the world’s second largest economy and biggest polluter understands that “greenhouse gases from industry, transport and shifting land-use poses a long-term threat to China’s prosperity, health [...]
The 2011 Hurricane Irene (there was an Irene in 1999 too) was formed on August 20 and eventually dissipated nine days later. It’s stint affected the Caribbean and eastern North America. The storm, which developed and escalated quickly, sent many scrambling for hardware, catastrophic health insurance, food supplies and evacuation. Irene devastated caused quite a [...]
In the first study of its kind, a group of researchers have quantified the financial impact of climate-change infused natural disasters on health care in the U.S., during the past decade. Floods, famines, fires and other natural disasters are reported to have cost the US government $14 billion in lost lives and and heath care [...]
Recent figures published in a report prepared by the European Commission’s Joint Research Centre and PBL Netherlands Environmental Assessment Agency show that the world’s CO2 emissions have been steadily and significantly growing during the past two decades, reaching an all time peak this past year. Carbon dioxide emissions, the main cause of global warming, rose 45 [...]
Recently, China’s Yellow Sea has been clogged for a surface of nearly 7,700 square miles (20,000 square kilometers) by a massive algae front. Surprisingly enough, the algae spanning across great distances off the eastern provinces of Shandong and Jiangsu is a year to year visit, although authorities believe this year has been a bit more [...]
According to a new study released by the National Oceanic and Atmospheric Administration (NOAA), tiny solid and liquid particles in the atmosphere, resulting from human and natural pollution, have kept the Earth from warming at the estimated level. The reduction of global warming effects by stratospheric aerosols has been significant for the past dozen years, [...]
It’s pretty evident for anyone living in a big, crowded city what pollution looks like and to what degree our health is affected by it. Besides things like your lungs or skin, scientists relate in a new study published in Molecular Psychiatry, how they believe pollution can cause memory loss. To prove their point, they [...]
The river Ganges has literally been at the center of Indian life for thousands of years, both socially and spiritually. Millions of people have been fed, bathed and enlightened by it. It’s a sacred river, regarded as the most important stream in Hindu mythology – it’s also very dirty. The Ganges is considered to be [...]
Pollution can take numerous and unexpected shapes; one of the not-so-deadly, but still extremely unpleasant types is noise pollution. You probably don’t notice it because it’s so common, but it’s a really noisy world out there; if for a few days you were to go somewhere far away from all the fuss and noise that [...]
A week before the UN Copenhagen climate summit, a disheartening new study conducted by scientists from University of Exeter in the United Kingdom, along with the University of East Anglia, shows that the world greenhouse gas emissions could reach record high in 2010, outranking the previous 2008 high. The data supports the idea that as [...]
To be quite honest, I was never really fond of the man, but ever since he quit his executive positions at Microsoft, I’m starting to like him more and more. The reason is not that he’s giving money away, but the causes he’s giving the money for. I’m not really sure how practical this idea [...]
I was surprised to talk to a bunch of people today and find out they didn’t know about this, so I figured this is definitely something worth knowing. Here’s the deal. There’s a whole lot of garbage floating around; a whole lot ! Some are above the surface, some are below. What happens is they [...]
Mankind is screwing up. I’m sorry, that’s just the way it is. Not taking care of our natural resources, polluting and destroying habitats, it’s obvious that we, as a species, made some pretty big mistakes, the combined effects of which will come back to haunt us (and already are). But that’s not to say that [...]
Most of the talk about global warming revolves around carbon dioxide, sometimes giving the false impression that it alone is responsible for global warming and all its implications. However, numerous studies have revealed a new enemy, one almost as dangerous as carbon dioxide: soot. The black powdery pollutant is responsible for numerous climatic shifts, especially [...]
Technology has developed so much in these years that scientists are finding more and more brilliant ways to clear out the pollution that fills our lungs and to solve problems that trouble the very existence of our mankind in ways that sometimes surprise all of us. Often, for the most complex issues we have to [...]
Some places in the world are just like heaven, some are just like hell; almost literally. Human activity can sometimes have devastating effects not on just the environment, but on the population too. Here’s a list of five of the most polluted cities in the world, in no specific order. Linfen, China Potentially Affected People: [...]
Photo by Stefan Everybody (or almost everybody) believes that no matter what, USA remains “polluter no. 1″. Don’t take my word for it, just ask BBC’s environment analyst Roger Harrabin – he says the same thing. The industry is by far the most developed, so that would seem logical, despite the fact the China and [...]
A recent study has shown that certain types of air pollution can actually help by creating extra doses of atmospheric cleaner. Of course, we’re talking about just a small fraction of the total pollution which triggers the right chemical process. The lab study pointed out that nitrogen oxides (which result mostly from agricultural pollution) can [...]
Despite of the all the efforts (which by the way, are not as numerous as you may think) which have been done, pollution and global warming are still “hot” topics, with no great solution in sight. Some studies claim that things are not as bad as we believe, others claim that it’s worse. Still, one [...]
The fight between health and industry is more intense than it has been for many years and as a result, numerous studies are conducted on the matter, and to be more precise, to find out how pollution shortens life expectancy, especially in children. But there are some gaps in information and implementation, according to [...]
