New York, June 9, 2017: Using specially equipped Google Street View cars to measure air quality on a block-by-block basis, researchers, including one of Indian-origin, have developed a detailed and extensive local map of air pollution for an urban area.

Most large urban areas tend to have only one air quality monitor for every 100 to 200 square miles. In comparison, the new mobile approach maps air pollution every 100 feet, or at about four to five locations along a single city block.

“Using our approach and analysis techniques, we can now visualise air pollution with incredible detail. This kind of information could transform our understanding of the sources and impacts of air pollution,” Apte added.

The research was conducted in partnership with the US-based non-profit Environmental Defense Fund (EDF), Google and Aclima, a California-based provider of environmental sensors.

By integrating Aclima’s sensor system into Google Street View cars, the team mapped air pollution in 78 square miles of Oakland, California, over an entire year, collecting one of the largest data sets of air pollution ever measured of single city streets.

This new technique maps urban air pollution at 100,000 times greater spatial resolution than is possible with traditional government air quality monitors, according to a study published in the journal Environmental Science & Technology.

The team believes that their hyper-local mobile measurement system could be implemented in many cities throughout the world, providing detailed air quality information for citizens, families, local governments and scientists.

The new technique could address major air quality monitoring gaps worldwide and has the potential to transform the way air pollution is monitored in urban areas as well as shed light on the health effects on city dwellers.

“You could use this information when you’re picking a school for your kids. Is there a school with a playground that might have better air quality because your kid has asthma,” Apte said.

“This hyper-local information about consistent air quality can be really useful for people, especially those who are vulnerable because of age or health condition,” Apte noted.(IANS)

Exposure To Air Pollution Linked To Breast cancer: Study

Government can plan for new designs for industrial and commercial facilities to cut down on the occupational exposures.

Women working near busy roads are at high risk of developing breast cancer, due to traffic-related air pollution, researchers have warned.

The team, from University of Stirling in Scotland, analysed the case of a woman who developed breast cancer after spending 20 years working as a border guard at the busiest commercial border crossing in North America.

The woman was one of, at least, five other border guards who developed breast cancer within 30 months of each other and, at another nearby crossing, a cluster of seven other cases was noted.

According to Michael Gilbertson, the findings “infer a causal relationship” between breast cancer and very high exposures to traffic-related air pollution containing mammary carcinogens. A link between nightshift work and cancer was also identified.

“This new research indicates the role of traffic-related air pollution in contributing to the increasing incidence of breast cancer in the general population,” Gilbertson said.

The group of women all developed a cancer believed to have been caused by exhaust fumes in what researchers have branded a ‘new occupational disease’.

There is a one in 10,000 chance the cases were a coincidence, the study published in the journal New Solutions said, because the cancers were all so similar and close together.

A review of previous research confirmed that BRCA1 and BRCA2 genes — which try to stop tumours growing — can be “silenced” by exposures to dioxins and polycyclic aromatic hydrocarbons – both found in exhaust fumes.

BRCA2 gets rapidly degraded in the presence of aldehydes – also components of exhaust fumes.

“There is much more research to be undertaken,” Gilbertson said. “But we now have plausible mechanisms for inferring how the BRCA1/2 tumour suppressors in this highly-exposed border guard became dysfunctional and likely contributed to the ongoing epidemic of sporadic, early onset, premenopausal breast cancer among her colleagues.

“With this new knowledge, industry and government can plan for new designs for industrial and commercial facilities to cut down on the occupational exposures to traffic-related air pollution,” Gilbertson said. (IANS)
