Worst Air Quality Cities

  • Linfen, China

Today, the city is one of the most polluted worldwide. It also comprises numerous coalmines, which do considerable damage.

  • Bakersfield, California

Residents from Bakersfield breathe some of the most polluted air in the country. The region ranks highest in 24-hour peak averages and annual fine particulates. The area further features the second-highest ozone pollution level in the country.

  • New Delhi, India

According to findings by World Health Organization, New Delhi ranks second in particulate concentrations. The report further reveals that the major source of the city's air pollution is dust from overcrowded roads and car exhaust. Consequently, taxi drivers and construction workers face the most risk for debilitating condition or even premature death.

  • Mexico City

According to research, Mexico city has elevated concentrations of almost every major damaging airborne pollutant, including nitrogen oxides, sulfur dioxide, and carbon monoxide. The city also grapples with the huge smog that hangs over it virtually every day.

  • Chongqing, China

The resulting poor air quality is affecting the residents' health. For instance, studies reveal that 4.63% of children below 14 years have asthma though the incidence in girls may be inaccurate because of cultural bias. Nitrogen oxide levels are also increasing due to vehicle emissions.
