Air Pollution Can Worsen Bone Health

Some of the effects of air pollution on health are well documented-lung cancer, stroke, respiratory diseases, and so on-but for others there is less scientific evidence. Such is the case of bone health: there are only a few studies and results that are inconclusive. Now, a study in India led by the Barcelona Institute for Global Health (ISGlobal), an institution supported by ‘la Caixa’, has found an association between exposure to air pollution and poor bone health.

Osteoporosis is a disease in which the density and quality of the bone is reduced. Globally, it is responsible for a substantial burden of disease and its prevalence is expected to increase due to aging of the population. The new study performed by the CHAI Project, led by ISGlobal and published in Jama Network Open, analysed the association between air pollution and bone health in over 3,700 people from 28 villages outside the city of Hyderabad, Telangana.

The authors used a locally-developed model to estimate outdoor exposure at residence to air pollution by fine particulate matter (suspended particles with a diameter of 2.5 µm or less) and black carbon. The participants also filled a questionnaire on the type of fuel used for cooking. The authors linked this information with bone health, assessed using a special type of radiography that measures bone density, called dual-energy X-ray absorptiometry, and measured bone mass at the lumbar spine and the left hip. The results showed that exposure to ambient air pollution, particularly to fine particles, was associated with lower levels of bone mass. No correlation was found with use of biomass fuel for cooking. ‘This study contributes to the limited and inconclusive literature on air pollution and bone health,’ explains Otavio T Ranzani, ISGlobal researcher and first author of the study. Regarding the possible mechanisms underlying this association, he says ‘inhalation of polluting particles could lead to bone mass loss through the oxidative stress and inflammation caused by air pollution.’ Annual average exposure to ambient PM2.5 was 32.8 µg/m3, far above the maximum levels recommended by the World Health Organisation (10 µg/m3). Around 58 per cent of participants used biomass fuel for cooking. ‘Our findings add to a growing body of evidence that indicates particulate air pollution is relevant for bone health across a wide range of air pollution levels, including levels found in high income and low- and medium-income countries’ says Cathryn Tonne, coordinator of the study and of the CHAI project.

Nominations open for CSP Today India awards 2013


The inaugural CSP Today India awards ceremony takes place on March 12, and CSP developers, EPCs, suppliers and technology providers can now be nominated.

CSP has made tremendous progress since the announcement of the Jawaharlal Nehru National Solar Mission in 2010. With Phase I projects now drawing closer to completion, the first milestone in India’s CSP learning curve is drawing closer. CSP Today has chosen the next CSP Today India conference (12-13 March, New Delhi) as the time for the industry to reflect upon its progress and celebrate its first achievements.

At the awards ceremony, industry leaders will be recognized for their achievements in one of 4 categories: CSP India Developer Award, CSP India Engineering Performance Award, CSP India Technology and Supplier Award, and the prestigious CSP India Personality of the Year.

Matt Carr, Global Events Director at CSP Today, said at the opening of nominations that “CSP Today are excited to launch these esteemed awards, which will enhance the reputation of their recipients. I am particularly excited to launch the CSP India Personality of the Year award, a distinguished honor for the industry figure deemed worthy by their peers.”

All eyes will be on the CSP Today India 2013 Awards when nomination entry closes on February 4 and the finalists are announced on February 11. The awards are open to all industry stakeholders to nominate until February 4 at
