Coronavirus can travel twice as far as official ‘safe distance’ and stay in air for 30 minutes, Chinese study finds
  • Authorities advise people to stay 1-2 metres apart, but researchers found that a bus passenger infected fellow travellers sitting 4.5 metres away
  • The scientists behind the research said their investigation also highlighted the importance of wearing face masks because of the length of time it can linger


IQAir takes action against deadly coronavirus

At the peak of the Chinese Spring Festival, the outbreak of the newly discovered coronavirus (2019-nCoV) epidemic threatened millions, with the World Health Organization, Centers for Disease Control, and numerous other international health agencies issuing official warnings.

In response to the deadly outbreak, the Chinese National Health Commission held a conference on January 22, 2020, to assess the public health crisis posed by this new virus.

Can clean air increase child IQ?

Intellectual Quotient (IQ) is an imperfect predictor of many outcomes, such as academic performance and lifetime earning potential. But researchers continue to find a correlation between air quality and children’s performance on IQ tests.

The accuracy of IQ test scores as direct indicators of future academic and financial success is controversial. Indeed, IQ tests vary in competency and don’t always accurately portray the intelligence of an individual. However, many experts still find it be a valuable measurement tool.

Impact of air pollution on health may be far worse than thought, study suggests

Results chime with earlier review indicating almost every cell in the body may be affected by dirty air.


The number of health problems linked to air pollution could be far higher than previously thought, according to research suggesting hospital admissions for conditions ranging from heart failure to urinary tract infections increase as air becomes dirtier.

Hanoi air pollution rises to unhealthy highs

Air quality in Hanoi has deteriorated over the last three days and is unlikely to get better in the coming days, experts say.

The capital's Air Quality Index (AQI) was recorded at 136 on Tuesday evening by 11 air monitoring stations scattered throughout the city.

Air pollution linked to mental health issues, research suggests

Areas with worst air quality had 27% increase in bipolar disorder analysis found.

People who grow up in areas with poor air quality are more likely to develop depression and bipolar disorder in later life, a new study has suggested.

Analysis of health data from millions of patients found a “significant link” between mental health disorders and exposure to air pollution, especially in childhood.


Microplastics from car tyres could be stunting children’s lung growth, investigation finds

The lung development of children could be stunted by the release of microplastics from car tyres, according to an investigation.

Toxic particles emitted from all vehicles including exhaust fumes, metallised rubber and brake dust, are contributing to poor air quality in cities, a study for Channel 4's Dispatches has discovered.

The findings came from an experiment conducted by the programme and scientists from King's College London (KCL).

Do cheap air purifiers really work?

With so many different air “purifiers” available for a vast range of prices, it may be difficult to decipher what is worthwhile and what is, well, worthless. It can be tempting to settle for an inexpensive air purifier, especially when it is promoted with jargon and promises.

Hanoi air quality still among Southeast Asia’s worst

Hanoi has seen air quality improve over the past year but it remains one of Southeast Asia’s most polluted cities.

The city’s average PM2.5 level last year was 40.8 micrograms per cubic meter of air as opposed to 45.8 in 2017, according to Switzerland-based air quality monitor IQAir AirVisual's 2018 World Air Quality Report.
