Editing Lima (section)

====Air====
Lima suffers the most from air pollution. The microscopic sediment contained within engine exhaust and industrial emissions floats in the air for extended periods of time, either continuing as air pollution or eventually coming to settle as dust upon different urban surfaces. The fine particles are the most dangerous, as if inhaled, are able to damage the human [[respiratory system]]. The recommended limit of these particles by the [[World Health Organization]] is 5 tons/km2/month. In February 2014, Lima recorded an average of 15.2 tons/km2. The two districts with the highest concentration of sedimentary dust are El Agustino (46.1 tons/km2) and Independencia (25.5 tons/km2) in February 2014.<ref name="limacomovamos.org"/><ref name="ReferenceA">{{cite web |url=http://www.inei.gob.pe/media/MenuRecursivo/boletines/estadisticas-ambientales-febrero-2014.pdf |archive-url=https://web.archive.org/web/20141113233105/http://www.inei.gob.pe/media/MenuRecursivo/boletines/estadisticas-ambientales-febrero-2014.pdf |url-status=dead |archive-date=13 November 2014 |title=Estadísticas Ambientales |date=February 2014 |website=inei.gob.pe }}</ref>
