GENEVA (Reuters) - The World Health Organisation (WHO) on Wednesday issued its first air quality guidelines since 2005 aimed at reducing deaths from key pollutants that cause cardiovascular and respiratory diseases.
The United Nations agency, in advice to its 194 member states, slashed the recommended maximum levels for several pollutants, including particulate matter and nitrogen dioxide, both of which are found in fossil fuel emissions.
