China study suggests that air pollution causes reduced ‘cognitive intelligence’

A detailed new study shows strong links between air pollution and loss of ‘cognitive intelligence’. While the study cannot prove air pollution is the culprit, the researchers consider it likely.

This adds to concerns about the effect of air pollution on health, which are already well recognised.  The BBC report notes that: “about seven million people die every year from exposure to polluted air” and “air pollution caused 4.2 million deaths globally in 2016“.

The World Health Organisation (WHO) sets ‘guideline values’ to minimise impacts of air pollution. Link.  However, these values are largely ignored by Heathrow and its pals at the Department for Transport because they are are much less stringent than EU ‘limit values’.
