Even low arsenic exposure a risk in Bangladesh water
Paris (AFP) June 19, 2010 - More than a fifth of deaths in a district of Bangladesh were caused by the country's notorious problem of arsenic-tainted well water, and even relatively low exposure to the poison was not risk-free, The Lancet reported on Saturday. By some estimates, between 35 and 77 million people have been chronically exposed to arsenic-contaminated water as a result of a catastrophically misguided campaign in the 1970s. Millions of tube wells were drilled in the aim of providing villagers with clean, germ-free water. By tragic irony, many wells were dug into shallow layers that were heavily laced with naturally-occurring arsenic. Several investigations have highlighted the health danger from this water, but they have been questioned on methodological grounds.

These probes provided an overall snapshot but not an individual one. In other words, they failed to explain how much of the tainted water a person may have drunk and what level of contamination was enough to cause sickness. Seeking to find out, doctors assessed 11,746 people aged 18 to 75 in Araihazar in the Dhaka administrative division. The physicians checked the volunteers' overall health and took blood and urine samples every two years. They also took samples of the local well water to monitor for arsenic levels. After six years, 407 deaths had occurred from all causes, 21 percent of which could be attributed to arsenic concentrations above the UN's recommended threshold. Of deaths linked to chronic disease, 24 percent were associated with exposure to the poison at such levels. The death rate rose in line with the exposure. Compared to those exposed to the lowest arsenic levels (less than 10 microgrammes of arsenic per litre of water), those with levels of 10-50 microgrammes had a 34 percent higher risk of death, and those with the highest level (between 150 and 864 microgrammes) a 64-percent higher risk.

But even exposure at relatively lower levels carried a risk, a finding that is important for other countries -- there are more than 70 of them around the world, including the United States, India and Mexico -- that face a serious arsenic problem. In the study, 23 percent of the volunteers were exposed to water with up to 10 microgrammes of arsenic per litre, which is the UN recommended maximum. Twenty-one percent were exposed to concentrations of between 10 and 50 microgrammes, with 50 microgrammes the current Bangladesh standard. Thirty-one percent were exposed to between 50 and 150 microgrammes; and 25 percent to between 150 microgrammes and the maximum tested level, of 864 microgrammes. Given the long-term effect of arsenic, taking a temporary break from exposure was no solution, for the risk of death remained the same, the researchers found. Chronic exposure to arsenic is linked with cancers of the liver, kidney, bladders and skin, as well as heart disease. The UN's World Health Organisation (WHO) has called Bangladesh's arsenic crisis "the largest mass poisoning of a population in history."

Tel Aviv, Israel (UPI) Jun 18, 2010
Israel may be celebrating the discovery of giant offshore gas fields that are expected to transform its economy, but its hopes of overcoming its acute water problems have been set back by Turkey, its erstwhile ally.

The Islamist government in Ankara has shelved plans to sell the Jewish state 1.75 billion cubic feet of water a year for 20 years from the Mavganat River in Anatolia, part of its wider strategy of restoring the regional dominance it had a century ago.

The Turkish decision to suspend the project was in retaliation for the May 31 killing by the Israeli navy of nine Turks aboard a Turkish-flagged ship carrying humanitarian to the Israeli-blockaded Gaza Strip.

Turkish Energy and Natural Resources Minister Taner Yildiz says Ankara will not develop any joint projects with Israel until it "apologizes and expresses its regret" for the attack in international waters in the eastern Mediterranean.

The May 31 attack was the latest in a series of incidents over the last few years that have soured relations between the two states and taken them to the brink of severing diplomatic relations.

Ankara has also halted a plan to supply Israel with natural gas from Russia via Turkey through an underwater gas pipeline across the eastern Mediterranean, part of the Blue Stream 2 project.

Relations have been deteriorating steadily since Israel invaded the Hamas-controlled Gaza Strip in December 2008 and killed some 1,200 Palestinians, mainly civilians. Ankara bitterly denounced that action.

Now that the Jewish state has its own gas fields, which industry experts say could contain up to 25 trillion cubic feet of gas, the loss of the gas pipeline is a minor irritant in economic terms.

But the block on the water project is a greater setback for a country whose water resources, partly in the occupied West Bank, are shrinking.

Both state-sponsored programs have been in abeyance for several years.

The Mavganat plan, first mooted 20 years ago, was to ship water from Turkey in converted oil supertankers across the eastern Mediterranean.

The river flows into the Mediterranean near the port of Antalya on Turkey's southern border where a $150 million water export hub was built in preparation for the project.

The Mavganat is capable of producing 6.3 billion cubic feet of water a year for export across the region, including Cyprus, Syria, Jordan and even the Persian Gulf states.

Ankara was ready to provide the water to cement its 1996 military cooperation pact with Israel, a strategic alliance that drew together the region's two non-Arab military powers.

Ankara was also prepared to sell this valuable resource to other states, even as far afield as Libya and the Persian Gulf, to promote Turkey as the regional power as it had been until the Ottoman Empire was carved up by the British and French after World War I.

However, back in the early 1990s, pipelines to carry the water around the region were rejected by the governments concerned. They were reluctant to put themselves in a position where Ankara would have control over such a critical resource.

In June 2000, Israel and Turkey signed a preliminary agreement on the Mavganat project. But little more was heard of it until June 2006, when the Israeli government said it was considering canceling the project, citing high costs of around $1.34 billion over the 20-year period.

The feeling at the time was that desalination plants were more feasible to solve Israel's perennial water problems. It preferred a water pipeline from Turkey, but that would have to pass through arch-enemy Syria, and probably Lebanon as well, which made it highly insecure.

Finally, on Aug. 6, 2006, then Israeli Prime Minister Ariel Sharon signed an agreement on the water project in Jerusalem with Turkey's then-energy minister, Zeki Cakan, and agreed to set up a joint committee to deal with transportation.

But the project again slipped into abeyance because both sides agreed that high oil prices at the time made the cost of transporting the water in giant tankers prohibitive.

Turkish privatization of the water treatment facilities at the mouth of the Mavganat also pushed up the cost of the water for Israel. Now the project may never get off the ground.

Robot Submarine Patrols Lake Michigan For Climate-Change Study
West Lafayette INw (SPX) Jun 17, 2010
Researchers at Purdue University are using a robotic submarine and other specialized tools in Lake Michigan to gather biological and environmental data showing how young fish vital to the ecosystem may cope with future climate change. The researchers are correlating larval fish growth with various factors, including water temperatures near the lakeshore, where wind patterns might be altere ... read more
