Frequent trips on the subway are harmful to health

Frequent and long trips on the subway can be harmful to health, according to scientists from the University of Southampton.

Experts compared dust samples collected from European metro stations with samples from wood-burning stoves and a car tunnel. During the experiment, the researchers found that samples from the subway contained a high concentration of iron, copper and other metals.

After this, scientists proved that dust is capable of generating reactive molecules. Moreover, the smaller the particles, the greater the degree of their toxic effects. Larger dust particles can stick to the trachea and nasal walls, while smaller ones can reach the bronchioles.

“The high level of mechanical activity on the underground railroads, along with very high temperatures, play a key role in the generation of this metal-rich dust to which large numbers of people are exposed. This means that more research is needed into its impact on public health,” said Matt Loxham, one of the authors of the experiment.

In response to this, the head of the British Underground, Howard Collins, said that the dust content in the subway does not exceed the norm. However, he noted that if there is evidence of danger and harm to the health of citizens, the standards will be changed.

Thus, regular trips to the subway can be harmful to health due to the increased content of metals in dust. Although the level of pollution does not yet exceed the norm, scientists recommend further research.
