Metals, particularly nickel and vanadium, and sulphate particles -- components of fine particulate air pollution (PM2.5) -- can worsen asthma and lead to hospitalisation, according to ...

The study showed that for each decile increase in the pollutant mixture, asthma hospitalisations increased 10.6 per cent in children and 8 per cent in adults ...

Over very long intervals, short-term random fluctuations (“noise”) cancel one another – and ever clearer and steadier signals emerge.

Metals, particularly nickel and vanadium, and sulfate particles are the components of fine particulate air pollution (PM2.5) that most strongly contribute to the association between long-term exposure ...
