Sterlite effects
Is there data to suggest Sterlite's operations may be harming health in Thoothukudi?
In 2008, the Department of Community Medicine, Tirunelveli Medical College submitted a report titled “Health Status and Epidemiological Study Around 5 km Radius of Sterlite Industries (India) Limited, Thoothukudi.” The study covered a population of 80,725 people and compared the health status in villages around Sterlite with the average health status prevailing in the state and two other locations that did not have any major industries. The health report is a well-kept secret because of what it found.
At the time of the study (2006 and 2007), Sterlite had been operating at a far lower production capacity of between 70,000 and 170,000 tonnes of copper anode per annum (tpa). It was only in 2005 that it was permitted to manufacture at an expanded capacity of 300,000 tpa.
"Since 2007, Sterlite has been operating a 400,000 tpa smelter, nearly six times larger than what it began with in 1996."
The findings of the study are revealing:
1. Iron content in the groundwater in Kumareddiapuram and Therku Veerapandiapuram, the site of the ongoing protests, were 17 and 20 times higher than permissible levels prescribed by the Bureau of Indian Standards for drinking water.
Chronic exposure to iron through drinking water could result in chronic fatigue, joint pain, and abdominal pain.
2. At 13.9%, respiratory diseases were significantly more prevalent in the areas surrounding the factory than in areas without industry and this was much higher compared to the state average. The incidence of asthmatic bronchitis is 2.8%, more than double the state average of 1.29%.
Bronchitis is an inflammation of the airways lining caused by long-term exposure to environmental irritants such as tobacco smoke, dust or chemicals. Asthma is a condition where the muscles around the airways get tight resulting in the narrowing of the airways. Asthmatic bronchitis is a condition where asthma and bronchitis occur together.
The report finds that “The increased prevalence rate of asthma and respiratory infections are due to the air pollution caused by industries and automobiles in the area.”
3. The study also found that there were more people suffering from Ear, Nose, Throat (ENT) disorders near the factory. Among the ENT diseases, pharyngitis and sinusitis were very high. “Climatic conditions and atmospheric pollution could be the cause for the prevalence of ENT morbidity,” the report concluded.
4. Myalgia, or general body pain, was another widely reported symptom in the study area closer to the factory.
5. “Women in the [study] area had more menstrual disorders, like menorrhagiae and dysmenorrhagiae. . .it needs an in-depth study,” the report stated.
This study has disturbing findings, since the high incidence of respiratory diseases found in 2007 was at a time when Sterlite was running at less than half its current production levels. Respiratory diseases are an indicator of air pollution which has been identified as the “world's largest single environmental health risk” by the World Health Organisation. WHO reports that in 2012, around 7 million people died – one in eight global deaths – as a result of air pollution exposure.
