High inorganic arsenic exposure to diabetes has been established earlier by studies in Bangladesh, Taiwan and Mexico. But the effect of low and moderate levels of arsenic was unknown. A study in the US has found that inorganic arsenic, even at low levels, may cause diabetes. Found in mineral deposits in rocks and soil, arsenic leaches into groundwater, which when supplied for drinking, can be harmful, say researchers of Johns Hopkins Bloomberg School of Public Health, USA.

The researchers studied data from the US National Health and Nutrition Examination Survey of 2003-04 for 788 adults. They found that individuals with diabetes had higher levels of inorganic arsenic compared to those without diabetes. Apart from contaminated drinking water, flour and rice can also contain small quantities of inorganic arsenic, if grown or cooked in areas with arsenic contaminated soil or water.

The study says that 8 per cent of the public water supply system in the US may exceed arsenic levels of 10 micrograms per litre, the US Environmental Protection Agency’s standard for arsenic concentration in drinking water.

“Estimated daily dietary intake of inorganic arsenic in the US ranges from 8.4-14 micrograms per day for various age groups,”

said the study published in the August 20 issue of the Journal of the American Medical Association.

This study predicts a grim future for India where arsenic poisoning is spreading to new areas. India is also called the diabetes capital of the world. However, one problem with the study is that the direct linkage between arsenic exposure and diabetes has not been explored.

“This is a cross-sectional study. Two observations have been made on the basis of data available. Only the association can be claimed, not the causality. The two things may happen together, but it’s not necessary that one causes the other. Further studies need to be carried out,”

said Nikhil Tandon, professor in the Department of Endocrinology and Metabolism, AIIMS, Delhi.

Shashank R Joshi, endocrinologist at Lilawati Hospital and Research Centre, Mumbai, says,

“Arsenic related diabetes would form a very small percentage of the total diabetes in the country which is high, due to susceptible genes, bad diet and lack of exercise.”

The trade talks at the World Trade Organization headquarters in Geneva collapsed in the last week of July. The Union minister for Commerce, Kamal Nath, said India would not accede to the demands of developed countries at the cost of Indian farmers. Nath seems to have become a hero in many quarters in the country and in other developing countries—and a villain amongst developed countries for allegedly scuttling free trade negotiations. But in reality, he has virtually complied with all conditions of the wto agriculture text, including almost zero farm subsidy reduction by developed countries. And the talks actually collapsed because the us did not want to make any commitment to cut massive subsidies to cotton growers.

India had three main demands before the commencement of the meet. It wanted reduction in subsidies to farmers in developed countries and increase in the number of special products—items on which developing countries have flexibility to raise import tariff because these items are important for food, livelihood security and rural development. India also wanted a simplified Special Safeguard Mechanism (ssm) that would allow developing countries to raise tariffs to protect farmers from surging imports. But at Geneva, India did not raise the first two issues at all. The issue of ssm was stonewalled by the us.

The real spoilsport

On the eighth day of the ministerial, the European Union brokered a proposal on ssms. The proposal said that developing countries could hike import duties/ tariffs to any level, if they could prove, in 60 days, that glut in imports or fall in prices of imported goods is inimical to domestic livelihoods, food security and rural development. The draft circulated before the meet talked of limits on hikes in import duties.

Six of the G-7 countries including China and India agreed to the proposal but the us blocked it. US trade representative Susan Schwab said ssms in the present form “were very protective for developing countries and could not be accepted”.

“This was an excuse because if all countries had agreed to the us proposal, the next issue on the agenda would have been cotton subsidies which the us wanted to evade”

said Bhaskar Goswami of the Delhi-based think tank Forum for Biotechnology and Food Security.

“In 2007, the us doles out three billion dollars as cotton subsidy. This came down to one billion in 2008 because 38 per cent of land under cotton had been diverted to corn and other bio-fuel crops. At Geneva, the us would have been asked to cut down the subsidy by 70 per cent and that would have created trouble in an election year,” Goswami explained.

The us has already lost a wto dispute on cotton subsidies. “In 2003, it was criticized for protecting its 20,000 cotton growers impoverishing millions of cotton growers in the four African countries—Benin, Burkina Faso, Mali and Chad. The impact has been also borne by Indian cotton farmers who were priced out and committed suicide under pressure of heavy loans,” said Devinder Sharma who is also affiliated with the same think tank.

Withdraw

Meanwhile, farm movements in India are demanding complete exclusion of agriculture from WTO talks.

“Developed countries want to protect their agriculture though heavy subsidies and high tariff barriers and at the same time want access for their products in the developing countries. There can be no agreement unless the developed world drastically changes its attitude. So we believe that wto has become ineffective and needs to be wind up,”

said Krishan Bir Chaudhary, the president of the nationwide farmers’ organization Bharat Krishak Samaj.

“Free market will only lead to more suicides. We have to be completely self-reliant in agriculture and food and not accede to the will of multi-national companies,” said Chukki Nanjunda swamy of another farmers’ organization Karnataka Rajya Raitha Sangha, a farm organization.

The fact that wto director general Pascal Lamy has cut short his autumn break and is visiting India on August 10-12 and the us soon after shows how desperate he is to conclude the Doha Development Round which began in 2001. The talks might restart in September.

The researchers, Michael Worobey and team from the University of Arizona, say the finding will help in the development of an efficient vaccine against aids. The researchers say they studied blood samples of five patients who were among the first recognized aids victims; all of whom had immigrated to the us. They compared the samples with those of another 117 aids patients from different parts of the world and traced back the family history of the virus. The study appeared online on October 30, 2007 in the journal Proceedings of the National Academy of Sciences.

But many experts say the results might not be useful in developing a vaccine against the deadly virus. So far, an effective vaccine has been elusive as the character of the virus changes frequently from place to place.

“There are eight major subtype of HIV-1 in addition to the existing recombinants within the subtype which are accumulating and these type of changes are increasingly occurring as days progress which poses a great challenge to vaccine development” says Smarajit Jana, member of the National Aids Council in Delhi.

He says, “When an epidemic spreads, it goes to 3-4 different directions, not just to one area. So, a lot more archival samples have to be tested to get the truth.’ In India, the major circulating stain is the subtype C and scientists say the vaccine developed on the strain collected from one country may not be effective in other countries because of the very nature of the virus which is not predictable and changes rapidly.

Meanwhile, the report has sparked off a controversy outside the us . Haitians see it as a ploy to vilify the country. “This report is just an extension of a larger campaign by the us to squash the people’s movement in Haiti,’ said Noluthando Williams, a Haitian activist.

Small particles crossing the void are found to be losing more energy than those passing through space filled with matter.

“What has been observed is that the temperature of the cosmic microwave background (cmb) radiations is slightly lower in a region in the sky. cmb is the radiation we receive from the early universe when the universe was hotter and smaller than it is today,”

says Jasjeet Singh Bagla of the Harishchandra Research Institute, Allahabad.
