Research results show that worsening air pollution correlates with increased violent crime
by
Air pollution is known to cause respiratory and other illnesses and is known to reduce people's intelligence . A new study conducted by a research team at Colorado State University found that “aggravation of air pollution correlates with an increase in the number of violent crimes”.

The study was conducted by
The research team includes the National Incident-Based Reporting System , a crime-related database managed by the FBI, 2006-2013 air pollution data observed by the United States Environmental Protection Agency, and the Hazard Mapping System of the United States Marine and Atmospheric Administration. Three detailed data sets were cross-analyzed: wildfire smoke pollution data from satellite images provided.
As a result of analyzing the relationship between air pollution and crimes, crimes that are considered `` violent crimes '' by the FBI classification due to the increase in pollutants such as particulate matter (PM2.5) in the air It turns out that the incidence increases. For example, if the amount of PM2.5 increases by 10 micrograms per cubic meter, the incidence of violent crime increases by 1.4% and the ozone concentration, the main component of the photochemical oxidant , an air pollutant, increases by 0.01 ppm. Research teams say violent crime will increase by 0.97%.

On the other hand, only violent crime increased the rate caused by air pollution, and crimes classified into other categories, such as theft, did not increase. Bayham pointed out that the result of air pollution is not just a violent act, but may increase the number of remarks and rants that hurt someone. “Exposure may escalate as people become slightly aggressive when exposed to more pollution,” says Bayham.
The tool used by the research team to overlay air pollution data with crime data was originally developed to study the health hazards of air pollution. The tool developers measured how smoke and PM2.5 correlate with respiratory hospital admissions and asthma inhaler demand, but Burkhardt met with the developer of this analysis tool, He said he wanted to investigate how people's behavior changed by smoking.
“Several years ago, Fort Collins , where I lived, experienced a very severe wildfire. The smoke from the fire was so bad that I began to get frustrated in a few days. Frustration and aggression due to air pollution I was wondering if the increase in crime would appear in crime data statistics, ”Burkhardt said.
This study has only clarified the correlation between air pollution and crime rates, and the research team does not mention the physiological and mechanical relationships that air pollution affects people's behavior. Still, the economist's calculation said that by reducing PM2.5 by 10% per day, the government's spending related to crime can be reduced by 14 billion dollars (about 1.5 trillion yen). The research team claimed that it was the cost of air pollution that had been overlooked.
