London, Nov 1: Air pollution can increase the risk of death from kidney, bladder and colorectal cancer besides causing lung cancer, a study has showed.

According to researchers, air pollution represents a complex mixture of a broad range of carcinogenic and mutagenic substances that may play a role in chronic systemic inflammation, oxidative stress and DNA damage in tissues that could ultimately prove fatal.

“This research suggests that the effect of air pollution was not associated with death from most non-lung cancers, but the associations with kidney, bladder and colorectal cancer deserve further investigation,” said lead author Michelle Turner, researcher at the Barcelona Institute of Global Health (ISGlobal) in Spain.

For the study, published in the journal Environmental Health Perspectives, the team included more than 600,000 adults in the US and examined associations of mortality from cancer at 29 sites with long-term residential exposure to three ambient pollutants: PM2.5, nitrogen dioxide (NO2) and ozone (O3).

Over 43,000 non-lung cancer deaths were registered among the participants. PM2.5 was associated with mortality from kidney and bladder cancer, with a 14 and 13 per cent increase respectively, for each 4.4 µg/m3 (microgram) increase in exposure.

In turn, exposure to NO2 was associated with colorectal cancer death, with a 6 per cent increase per each 6.5 ppb (parts per billion) increment.

No significant associations were observed with cancer at other sites. (IANS)

A Simple Breakfast Toast Can Cause Air Pollution

Making a simple breakfast toast could contribute to a high level of indoor air pollution, say researchers.

According to a research by the University of Colorado Boulder, basic household tasks like boiling water or cooking your dinner or cleaning can leave your home as polluted as a major city.

“Homes have never been considered an important source of outdoor air pollution and the moment is right to start exploring that,” said Marina Vance, Assistant Professor at the varsity.

“Even the simple act of making toast raised particle levels far higher than expected,” she added.

For the study, Vance used advanced sensors and cameras to monitor the indoor air quality of a 1,200 square feet manufactured home. Over the course of a month, the team carried out a variety of daily household activities, including cooking a full Thanksgiving dinner. During the experiment, the measured indoor concentrations were high enough that their sensitive instruments needed to be recalibrated almost immediately.

Vance said it is apparent that homes need to be well ventilated while cooking and cleaning, because even basic tasks like boiling water over a stove top flame can contribute to high levels of gaseous air pollutants and suspended particulates, with negative health impacts.

Moreover, the airborne chemicals that originate inside a house do not stay there. The volatile organic compounds (VOCs) from products such as shampoo, perfume and cleaning solutions eventually escape outside and contribute to ozone and fine particle formation, making up an even greater source of global atmospheric air pollution than cars and trucks do, the researchers explained in the paper presented at the 2019 AAAS Annual Meeting in Washington.

While many traditional sources like fossil fuel-burning vehicles have become much cleaner than they used to be, and ozone and fine particulates are monitored by the US Environmental Protection Agency, but data for airborne toxins like formaldehyde and benzene and compounds like alcohol and ketones that originate from the home are very sparse.

“We need to re-focus research efforts on these sources and give them the same attention we have given to fossil fuels. The picture that we have in our heads about the atmosphere should now include a house,” the researchers said. (IANS)
