Fine particles from aircraft exhaust become more harmful over time, lab tests suggest

Fine particulate matter from aircraft exhaust becomes more harmful over time, according to lab tests.

The study found that these particles can penetrate deep into the respiratory tract and trigger oxidative stress, leading to serious health problems over time.

While the study does not directly impact seafarers, it highlights the potential health risks of air pollution in the shipping industry.

However, the article does not discuss any specific incidents or changes affecting seafarers' pay, jobs, or safety.
