A new report published by the World Meteorological Organization has said that air pollution in Lima is the highest in South America, local radio RPP reported.
Odon Sanchez, head of environmental research at Senamhi – the country’s national weather service – said most of the city’s outdoor air pollution came from transportation and factories.
Several of the city’s districts, Sanchez said, were also affected by the surrounding hills, which do not allow air to circulate.
The most affected districts, he said, were Comas, Carabayllo, Ate, Santa Anita, and Independencia.
Last February the country’s General Directorate of Environmental Health (Digesa) said Lima and Callao had seen a 52 percent decrease in the amount of air pollutants, over the past 10 years.
According to a 2011 poll cited by RPP, air pollution is Lima residents’ second biggest concern.
According to the World Health Organization about a quarter of the world’s population is exposed to unhealthy concentrations of air pollutants daily.
