“Although a hazy day generally has 2.9% higher risk [of death] than a day without haze, a very intense adverse effect is found on the mortality associated with mental and behaviour disorders,” the researchers reported. “A combined influence of haze, extreme weather/air quality and urban environment can result in extremely high mortality.” Read the full article @ The Guardian
The Hong Kong research, published in the journal Environment International, is the first to analyse the link of haze days and risk of death.
