Recent studies reveal that even minimal exposure to PM2.5, tiny soot particles, significantly increases cardiovascular and respiratory health risks.
Oliver Milman reports for The Guardian.
In short:
- Research indicates no safe level of PM2.5 exposure, linking it to increased hospitalizations for cardiovascular diseases.
- The WHO's recommended PM2.5 levels are surpassed in the US, UK, and EU, posing ongoing health threats.
- PM2.5, primarily from fossil fuel combustion, contributes to a range of diseases, including COPD and asthma.
