  • Fears of water contamination by unsupervised culling in Malir

    Experts have called for a better surveillance of poultry birds and use of a foolproof mechanism for the detection of the Avian Influenza virus. They regretted the recent elimination and disposal of hundreds of birds suspected to be infected with the H5N1 virus at a Malir farm was carried out under no official supervision. The poultry farmers' association maintained that the owner of the affected poultry farm, Mashallah Poultry Farm, had been persuaded to cull his birds kept in a farm in the jurisdiction of the Malir cantonment board at the earliest. He had been told time was of the essence in containing the outbreak. Health and poultry officials said they remained helpless in taking measures on a war footing as they were not taken into confidence as soon as an outbreak was reported. Following reports about bird deaths in a large number at a poultry farm on the National Highway, the surveillance staff of the Sindh livestock department collected samples from birds suspected to be suffering from some severe diseases for various laboratory tests on Feb 21. The news that the samples had been tested positive at the national reference laboratory in Islamabad for the H5N1 virus was received in Karachi on the night of Feb 23. Those officials responsible for culling remained unaware of the development for a long time and had no idea that havoc was being wrought by

  • A poison pill

    One thing Canada is not short of is lakes. It has so many that it can afford to set some aside to experiment on. And that is what Karen Kidd, an ecotoxicologist at the University of New Brunswick, has just done to a small lake in north-west Ontario. She has poisoned it in the name of science.

  • CDC criticised for delaying report on environmental health

    The US Centers for Disease Control has been accused of withholding data related to health risks in and around the Great Lakes area. But the agency says the report, pairing toxin concentrations with human health concerns, which was due out last year, had "deficiencies'.

  • Lawmakers claim Great Lakes report was 'suppressed'

    Lawmakers are again asserting that the Bush Administration is meddling in science. House Science Committee Democrats charge that federal officials have suppressed a report on potential health threats from pollution in the Great Lakes. They also say officials at the U.S. Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia, may have punished a career federal scientist who oversaw it. CDC says the report had genuine scientific flaws.

  • Bauxite mining: Parties threaten to prevent survey

    Political parties and tribals who have been agitating against bauxite mining are planning to block scientists of the Indian Council of Forest Research and Environment when they come for a survey. It is learnt that the scientists would visit the Agency areas soon to undertake a mining impact survey. This is mandatory to get permission for mining in a forest area from the ministry of environment and forests. The proposed mining project would displace tribals in large numbers and has also evoked sharp protests from environmentalists who warn that it would have a negative ecological impact.

  • Lankan waters heavily affected by pollution

    The waters around Sri Lanka are among the most heavily damaged and polluted ocean regions in the world, a study has revealed. The research by a team of American, British and Canadian researchers was published in yesterday's edition of Science. Activities like water and air pollution, overfishing, commercial shipping or greenhouse gas emission are continually damaging the planet and there is no sign that they will ever stop. Apparently, the most affected areas are "the North and Norwegian seas, South and East China seas, Eastern Caribbean, North American eastern seaboard, Mediterranean, Persian Gulf, Bering Sea, and the waters around Sri Lanka, the study said. The survey, analysing all 17 activities through which humans impact the oceans, and their conclusion was that every square mile of the ocean has been damaged in some way. The researchers have designed a map that emphasizes and explains the results of their study. The map was released at the annual meeting of the American Association for the Advancement of Science in Boston and published in yesteday's edition of the journal Science, the Associated Press reported. "Our results show that when these and other individual impacts are summed up, the big picture looks much worse than I imagine most people expected. It was certainly a surprise to me,' said lead author Ben Halpern, an assistant research scientist at the National Center for Ecological Analysis and Synthesis at the University of California, Santa Barbara, according to the Associated Press. The oceans around the polar areas are the least impacted, but scientists predict they will be damaged more and more in the following years, as long as the global warming continues. "There were two things we didn't anticipate,' Halpern added in the telephone interview. "Every single spot in the oceans was affected by at least one human activity ... we figured there'd be places people just hadn't gotten to yet.' Some good news is that, in the Congress yesterday, the House voted the approval of $454 million for ocean exploration programmes and studies over the next seven years, at the National Geographic and Atmospheric Administration. Ben Halpern still has hope that things can be improved. "There are some areas in fairly good condition. They are small and scattered, but have fairly low impact. That suggests that with effort from all of us, we can try to protect these patches and use them as a guideline for what we'd like the rest of the ocean to start looking like,' he stated. e-News

  • Water pollution by industrial effluents in India: Discharge scenarios and case for participatory ecosystem specific regulation

    Around the world as countries are struggling to arrive at an effective regulatory regime to control the discharge of industrial effluents into their ecosystems, Indian economy holds a double edged sword of economic growth and ecosystem collapse. This situation if mishandled can cause irreparable ecological harm in the long term well masked by short term economic prosperity.
