Toxic Waste’s Asian health impact similar to malaria’s

[MANILA] Toxic waste is an under-recognised major global health burden comparable to outdoor air pollution and malaria, according to a study.

The paper says that people’s exposure to industrial pollutants such as lead, asbestos and chromium from toxic waste sites in India, Indonesia, and the Philippines in 2010 resulted in the loss of 829,000 years of good health due to serious diseases or early death.

Such a health burden,

the researchers say, is comparable to that caused by outdoor air pollution and malaria — both serious problems in developing countries in Asia. The WHO estimates that people living in India, Indonesia and the Philippines lose a total 1.45 million healthy years per year because of outdoor air pollution and 725,000 healthy years due to


The researchers sampled 373 sites in the three countries. They found that these sites endanger more than eight million people as their daily exposure to industrial pollutants puts them at risk of developing heart disease, cancer and anaemia. The toxic wastes mainly come from tanneries, mining firms and battery recycling plants.


and women of childbearing age, who account for nearly two-thirds of the exposed population, are the most vulnerable as lead and cadmium harm brain development in children and may cause mild mental retardation.

The researchers estimate that there are a further 5,000 toxic waste sites in the three studied countries. With around 7,000 people on average living near each, this means that an additional 35 million people are exposed to these contaminants, they say.

The researchers say the data can help in drawing up and implementing public health policies to cut people’s exposure to these pollutants and remove contaminants that have entered the soil or groundwater.

According to study leader Kevin Chatham-Stephens, paediatric environmental health fellow at the Icahn School of Medicine at Mount Sinai, United States, the researchers used data from a global programme run by the Blacksmith Institute, an international non­profit organisation dedicated to solving pollution problems in developing nations, to identify waste sites in such countries.

They then assessed the likely health impact of exposure to pollutants from these sites.

“We focused on only one chemical per site and then estimated the amount of disease that would occur given the level of the chemical in the environment. We converted this incidence of disease into disability adjusted life years, which is a metric that attempts to incorporate both the disease and deaths associated with a disease,” Chatham-Stephens tells SciDev.Net.

Beau Baconguis, Philippines programme manager at environmental campaigning organisation Greenpeace Southeast Asia, says that exposure to toxic waste sites is a serious health concern that policymakers and industries need to address.

One way to do this, Baconguis says, is for governments to require companies to disclose what toxic chemicals they use. The firms should then be obliged to look for safer alternatives.

Red Constantino, executive director of climate policy think-tank the Institute for Climate and Sustainable Cities, Philippines, believes the study is a wake-up call for policy planners in emerging economies to rethink their idea of economic development.

“Economic growth continues to be a flawed yardstick because it does not measure wellbeing, and nowhere is this clearer than in the toxic-waste context,” he says. “Sustainability must be at the heart of developing-country strategies.”

The paper was published last month (4 May) in Environmental Health Perspectives.
