With more than 90% of the world’s population breathing toxic air, the World Health Organization says air pollution is a “silent public health emergency”. It is critical that governments adopt and enforce World Health Organization guidelines for air pollution immediately and that the industry coordinates its technological innovations with these guidelines. Public health policies that reduce fossil fuel–based energy generation and transportation will reduce greenhouse gas emissions and improve cardiovascular and respiratory functions, and mitigate health effects of climate change in general.
The scientist found that health benefits of clean air were almost immediate and long term. When China imposed factory and travel restrictions for the Beijing Olympics, lung function improved within two months, with fewer asthma-related physician visits and less cardiovascular mortality.
“I was surprised at how rapidly the benefits arise,” said Prof Dean Schraufnagel, at the University of Illinois at Chicago and lead author of the report. He further stated that the air pollution is an avoidable health risk, and that the increase of global warming awareness has raised the degree of urgency for pollution control. Public health policies and local measures, such as reducing traffic, can promptly reduce all-cause mortality within weeks.
These health benefits can also lead to dramatic cost savings. The benefits of the 1970 Clean Air Act in the US exceeded the costs of implementing it by a factor of 32 to 1, the US Environmental Protection Agency has estimated, and will amount to $2 trillion for the year 2020.
Some other local measures, such as shutting factories, can make a huge difference in terms of the air pollution. The good example is a steel mill in Utah Valley in the US that was shut for a year with the result that hospitalizations for pneumonia, pleurisy, bronchitis and asthma fell by half.
Reducing indoor pollution also makes a difference. Replacing polluting forms of heating, such as wood-burning stoves or gas heaters that lack vents or chimneys, with cleaner forms of heating, such as heat pumps, has a variety of benefits, including reducing days off school and visits to doctors, according to studies in the US, Australia and New Zealand.Some of the indoor air quality products and technologies will be introduced to our visitors at Ecotech China Air 2020. The main international brands displaying their products are Panasonic, Dream Maker, Zehnder, Aldes, Blauberg, Carel, Vortice, McQuay, just to name a few. With the technologies on display such as ventilation air systems, air purifiers, air conditioners, heat pumps, humidification &dehumidification units and air filters, our visitors will get the chance to see first-hand the latest innovations that help tackle air pollution.
