Washington, February 12: As per a study published in a US journal, people exposed to air pollution might develop criminal and fraud behaviour. This research reveals that air pollution may have potential ethical costs that go beyond its well-known toll on health and the environment.

“Our findings suggest that air pollution not only corrupts people's health but also can contaminate their morality," said lead author of the study, Jackson G. Lu of Columbia Business School. The experimental findings suggest that this association may be due to increased anxiety.

"Our findings suggest that air pollution not only corrupts people's health, but can also contaminate their morality," Lu added.

For the study, published in the journal Psychological Science, researchers examined air pollution and crime data for 9,360 US cities collected over a nine-year period.

The air pollution data included information about six major pollutants, including particulate matter, carbon monoxide, nitrogen dioxide and sulphur dioxide. The crime data included information about offences in seven major categories, including murder, aggravated assault and robbery.

The researchers found that the cities with higher levels of air pollution also tended to have higher levels of crime.

This association held even after the researchers accounted for other potential factors, including total population, number of law enforcement employees, median age, gender distribution, race distribution, poverty rate, unemployment rate, unobserved heterogeneity among cities and unobserved time-varying effects.

To establish a direct, causal link between the experience of air pollution and unethical behaviour, the researchers also conducted a series of experiments.
