Berkeley study shows ozone and nicotine a bad combination for asthma

Another reason for including asthma on the list of potential health risks posed by secondhand tobacco smoke, especially for non-smokers, has been uncovered. Furthermore, the practice of using ozone to remove the smell of tobacco smoke from indoor environments, including hotel rooms and the interiors of vehicles, is probably a bad idea.

Air pollution 'as bad as smoking in increasing risk of miscarriage'

Scientists called study’s findings upsetting and said toxic air must be cut.

Air pollution is as bad for pregnant women as smoking in raising the risk of miscarriage, according to a scientific study. They said the finding was upsetting and that toxic air must be cut to protect the health of the next generation.

Air pollution is already known to harm foetuses by increasing the risk of premature birth and low birth weight. Recent research has also found pollution particles in placentas.

90% of world's children are breathing toxic air, WHO study finds

Report says air pollution is having a devastating impact on children worldwide, storing up a public health time bomb

Poisonous air is having a devastating impact on billions of children around the world, damaging their intelligence and leading to hundreds of thousands of deaths, according to a report from the World Health Organization.

The study found that more than 90% of the world’s young people – 1.8 billion children – are breathing toxic air, storing up a public health time bomb for the next generation.

Air pollution particles found in mothers' placentas

New research shows direct evidence that toxic air – already strongly linked to harm in unborn babies – travels through mothers’ bodies.

Scientists have found the first evidence that particles of air pollution travel through pregnant women’s lungs and lodge in their placentas.

Toxic air is already strongly linked to harm in foetuses but how the damage is done is unknown. The new study, involving mothers living in London, UK, revealed sooty particles in the placentas of each of their babies and researchers say it is quite possible the particles entered the foetuses too.

Air pollution may harm cognitive intelligence, study says

Chronic exposure to air pollution could be linked to cognitive performance, a new study in China suggests.

Researchers believe that the negative impact increases with age, and affects men with less education the worst.

Over four years, the maths and verbal skills of some 20,000 people in China were monitored by the US-Chinese study.

Researchers believe the results have global relevance, with more than 80% of the world's urban population breathing unsafe levels of air pollution.

Low levels of air pollution linked to changes in the heart

Regular exposure to even low levels of air pollution may cause changes to the heart similar to those in the early stages of heart failure, experts say.


A study of 4,000 people in the UK found those who lived by loud, busy roads had larger hearts on average than those living in less polluted areas.

This was despite the fact people in the study were exposed to pollution levels below the UK guidelines.

Researchers called on the government to reduce air pollution more quickly.

Air pollution cause of chronic diseases in big cities in Vietnam

VietNamNet Bridge – An increasing number of people are now suffering from cancer, acute and chronic respiratory diseases and allergic reactions in big cities in Vietnam as a result of air pollution.

One man from the northern province of Ha Nam was hospitalized for a long lasting chronic cough and breathing problems. Doctors discovered that he was actually suffering from chronic obstructive pulmonary disease due to polluted air.

Vietnam air pollution among the worst in the world

The quality of the environment in Vietnam has steadily dropped compared to other nations in the world, according to the Environmental Performance Index (EPI), which is compiled by prestigious global environmental centers.

The survey is coordinated by scientists from the environmental studies centers of Yale University and Columbia University in the US and in the European Union, who have carried out the research for years in 132 nations.

Air pollution in Vietnam cities hit unhealthy levels: government study

It's getting harder to breathe in Hanoi and Ho Chi Minh City. Here's the proof.

Hanoi, Ho Chi Minh City and the beloved tourist destination Ha Long are being plagued by severe air pollution, according to a new study released Thursday.

The environment ministry’s study between 2011 and 2015 found the air quality has become worse in many urban areas, especially the two largest cities and Ha Long.
