"Recent revelations about poor air quality at Melbourne’s Southern Cross
Station probably came as no surprise for passengers who have experienced such
conditions.
Train platforms, bus terminal and nearby areas have recorded alarmingly poor
air quality. In some parts of the station, nitrogen dioxide levels were more
than 90 times the World Health Organization’s (WHO) recommended limit. At such
levels, considered much higher than medically acceptable, human health is at
risk.
Poor air quality in train stations is a concern in many major cities, including
Sydney, New York and Boston in the US, and London and Edinburgh in the UK. In
some Sydney stations and tunnels, air pollution was up to five times worse than
the WHO’s recommended limit.
Poor air quality is a result of fumes from diesel engines, restricted airflow,
station design and the wear of train components. These emissions include tiny
airborne particles. This fine particulate matter can cause illness and disease.
Passengers, workers and nearby residents may all be affected.
Solutions already exist. Investing in technology, alternative fuels,
electrification and better management of stations can improve air quality and
reduce the health risks. As with COVID, people can also reduce their exposure
by wearing suitable face masks, such as P2 and N95 masks."
