Almost a quarter of China's surface water remains so polluted that it is unfit even for industrial use, while less than half of total supplies are drinkable, data from the environment watchdog showed on Monday. Inspectors from China's Ministry of Environmental Protection tested water samples from the country's major rivers and lakes in the first half of the year and declared just 49.3 percent to be safe for drinking, up from 48 percent last year, the ministry said in a notice posted on its website (www.mep.gov.cn).

BP Plc removed a containment cap from its stricken Gulf of Mexico oil well on Saturday in the first step toward installing a bigger cap to contain all the crude gushing into the sea and fouling the coast. The maneuver released a torrent of oil that will spew unrestrained into the Gulf for four to seven days -- the time BP says it will take to put in place a bigger cap and seal. Officials say the new cap would capture all the oil leaking from the well and funnel it 1 mile upward to vessels on the water's surface. The new solution, 82 days into the worst oil spill in U.S. history, would not allow crude to billow out the bottom and the top, as the current cap does, said Kent Wells, senior vice president of exploration and production for BP. "The difference is one completely seals and the other didn't," Wells said.

Young rag-pickers sifting through rubbish are a common image of India's chronic poverty, but destitute children face new hazards picking apart old computers as part of the growing "e-waste" industry. Asif, aged seven, spends his days dismantling electronic equipment in a tiny, dimly-lit unit in east Delhi along with six other boys.

BP's boss met officials from an Abu Dhabi state fund on Wednesday as hopes for fresh investment and progress toward closing a leaking U.S. oil well lifted the company's battered shares. A United Arab Emirates official said Chief Executive Tony Hayward had met officials from Abu Dhabi Investment Authority (ADIA) during a routine visit. He spoke as speculation mounted of a stake purchase by a Middle East or Asian sovereign wealth fund to help BP ward off takeovers and pay the rising costs of the worst oil spill in U.S. history. The UAE official, speaking on condition of anonymity, said Hayward's visit was a scheduled one mainly for discussion of BP's concessions with Abu Dhabi National Oil Company (ADNOC).

BP Plc defended its embattled chief executive on Wednesday and denied he would soon leave as the company prepared to launch within days a new approach to ending the worst oil spill in U.S. history. CEO Tony Hayward, criticized for a series of public relations gaffes and failed efforts to end the disaster, has the full support of the company's board and will remain in his job, a BP spokesman said. The spokesman dismissed a Times of London report that Hayward would step down within 10 weeks. In response to the spill, big oil companies including Exxon Mobil Corp and Royal Dutch Shell said they would spend $1 billion to develop a new spill containment system for the Gulf of Mexico. It will aim for water depths up to 10,000 feet and have an initial capacity to contain 100,000 barrels (4.2 million gallons/15.9 million liters) of oil per day. The failed BP well is a mile below the ocean surface.

Pending court approval, several companies affiliated with National Car Rental will pay a fine of $475,000 for repeated violations of motor vehicle idling regulations at two New England airports: Logan International in Boston, Mass. and Bradley International near Hartford, Conn. What is so wrong about idling? Diesel combustion releases fine particles and gases into the air. Commonly called soot, these particles are typically smaller than 2.5 micrometers or 1/30 the width of a strand of hair and are easily inhaled and may cause respiratory harm. By law in many states (especially urban ones) idling too long is an issue.

Remember the debate about the subsurface "plumes" or oil released by the leaking BP well in the Gulf of Mexico? A new report released by the National Oceanic and Atmospheric Administration (NOAA), the U.S. Environmental Protection Agency (EPA) and the White House Office of Science and Technology Policy about subsurface oil monitoring in the Gulf of Mexico contains preliminary data collected at 227 sampling stations extending from one to 52 kilometers from the Deepwater Horizon/BP wellhead. The data shows that the movement of subsurface oil is consistent with ocean currents and that the concentrations continue to be more diffuse as you move away from the source of the leak. This confirms the findings of the previous report. The report comes from the Joint Analysis Group (JAG), which is comprised of the afore mentioned agencies and was established to facilitate cooperation and coordination among the best scientific minds across the government and provide a coordinated analysis of information related to subsea monitoring in the Gulf of Mexico.

It is well known that certain concentrations of air pollution can adversely affect human respiratory condition. What is not as well-known is how air pollution can affect the heart. A new study presented at the American Heart Association's Basic Cardiovasular Sciences 2010 Scientific Session by researchers from Texas A&M links ground-level ozone (smog) to cell deaths in the heart.

By now most people know about the BP oil spill in the Gulf of Mexico and its effects or potential effects on water quality and wildlife. Now the National Oceanic and Atmospheric Administration (NOAA) had released measurements of the air quality in the area. Scientists found common air pollutants, such as ozone, nitrogen oxides and carbon monoxide, in amounts typical of urban areas in U.S. cities. However, 15 to 70 kilometers downwind from the oil spill, concentrations of certain hydrocarbons were much higher than than would be found in urban air.

Two new fish species — with pancake-flat bodies, wiggling lures on their faces, and elbowed fins for "walking" on the seafloor — have been discovered in the path of spewing Gulf of Mexico oil. One of these pancake batfishes lives in the northern Gulf where oil is already spreading from the Deepwater Horizon blowout.

Stock in BP rose on Tuesday as the British oil major ruled out a share issue and talk persisted of sovereign wealth fund interest, while its Gulf of Mexico oil slick spread to the Texas coast. BP shares were up 3.7 percent after hitting their highest in two weeks. They at one stage had lost more than $100 billion in value in the 78 days following its April 20 oil rig explosion that unleashed the massive spill. Backing came from Royal Bank of Scotland, which upgraded the stock to 'buy' from 'hold'. The shares have drawn some support from talk that the company is a takeover target and has approached sovereign wealth funds with offers of a stake to ward off hostile bids.

Shareholders in British oil company BP balked at reports it would seek urgent investment from a wealthy Middle East or Asian country as clean-up costs for its U.S. oil spill topped $3 billion. Over the weekend, while U.S. Independence Day holidaymakers shunned Gulf of Mexico beaches tarred by the leaking well, media reports said BP was looking for a strategic investor among the sovereign wealth funds of the Middle East and Asia. An investor would help ward off a takeover and raise funds for the liabilities racking up behind the worst oil spill in U.S. history, the reports said.

A supertanker adapted to scoop up oil from the BP spill in the Gulf of Mexico began tests on Saturday amid a report that some major investors expect the energy giant to replace its top executives. The vessel named "A Whale" and dubbed a "super skimmer" is operating just north of the blown out well as part of a two-day test watched by the U.S. Coastguard, said Bob Grantham, spokesman for TMT Shipping Offshore, which owns the ship. If all goes to plan TMT hopes to sign a clean-up contract for the ship, which can remove up to 500,000 barrels (21 million gallons) of oil and water mix from the sea surface a day, according to crew members.

Environmental groups, BP and the U.S. Coast Guard reached tentative agreement on Friday on measures to prevent sea turtles from being incinerated alive in controlled burns of spilled oil in the Gulf of Mexico. The deal would settle a lawsuit accusing BP of violating the U.S. Endangered Species Act and terms of its lease with the federal government for the deep-sea well that ruptured on April 20, unleashing the worst offshore spill in U.S. history.

(Reuters) - A Kyoto Protocol scheme may be encouraging projects to emit more greenhouse gases because of incentives to earn carbon offsets from subsequently destroying these, a U.N. report said. The projects under investigation are the most lucrative under Kyoto's Clean Development Mechanism (CDM) and account for more than half carbon offsets sold under the scheme. Limiting their output could impact carbon prices.

The reporting of greenhouse gas emissions by major sources of these pollutants is gaining momentum. The U.S. Environmental Protection Agency (EPA) is finalizing requirements under its national mandatory greenhouse gas (GHG) reporting program for underground coal mines, industrial wastewater treatment systems, industrial waste landfills and magnesium production facilities. The data from these sectors will provide a better understanding of GHG emissions and will help EPA and businesses develop effective policies and programs to reduce them. Methane is the primary GHG emitted from coal mines, industrial wastewater treatment systems and industrial landfills and is more than 20 times as potent as carbon dioxide at warming the atmosphere. The main fluorinated GHG emitted from magnesium production is sulfur hexafluoride, which has an even greater warming potential than methane, and can stay in the atmosphere for thousands of years.

For the past 16 years the state of Texas has been issuing air quality permits to refineries and other major sources that permitted emissions caps on facilities, and allowed facilities to comply with the caps in a manner that gave them some operating flexibility while not exceeding the overall facility cap specified in the permit. This approach, also used in other states, is generally applauded by companies, regulatory agencies, and also by environmental groups. It is a win-win for everyone. So why did EPA void the program? First, state programs operate under authority delegated by USEPA, so EPA does have the right to disapprove a state program it deems to be inadequate under the federal Clean Air Act. A major problem with the EPA action disapproving the Texas permitting program is that there are existing sources in Texas permitted under the program that are relying on the permit terms in their existing permits and have based their business decisions on an existing established permitting program that has been in place since 1995.

America has been getting rid of its industrial base and as a result pollution will tend to decrease in America. Where does it all go? Other countries should know the bitter lessons of pollution should they not? Maybe yes and maybe no. Industry has gone to many other nations including China especially in the last decade. According to the People's Republic of China's own evaluation, two-thirds of the 338 cities for which air quality data are available are considered polluted. Respiratory, cancer and heart diseases related to air pollution are the leading cause of death in China. Meanwhile in Tehran, which is one of the most polluted cities of the world, there is a similar situation. Air pollution in the Iranian city of Tehran is not new. Ever since 1950 population and automobile ownership has risen dramatically.

Oil is no longer spewing into the Gulf of Mexico -- at least temporarily -- as BP Plc said it choked off the flow from its undersea well that ruptured in April and caused the worst offshore oil spill in U.S. history. BP said it stopped the leak on Thursday with the tight-sealing containment cap installed three days earlier atop its blown-out well, and awaited on Friday the results of tests on whether the well remains intact. That's a key issue as the British energy giant moves to plug the leak permanently with a relief well intended to intersect the ruptured well -- which extends 2.5 miles under the seabed -- and seal it with mud and cement next month.

BP Plc extended for another 24 hours a critical test of its blown-out Gulf of Mexico well that so far has shut off the huge oil leak, the top U.S. official overseeing the spill response said on Saturday. The British energy giant, which cut off the flow of oil from the deep-sea well on Thursday when it began the test to gauge its structural integrity, expressed growing confidence that the well was intact. Kent Wells, BP's senior vice president of exploration and production, said there was no evidence of any leaks. "We're feeling more comfortable that we have integrity" in the well, Wells added, in what would be an important step toward permanently plugging it.
