Air pollution is a big problem in Peru, especially in
Lima, the capital city, which is caused by industrial activity and vehicle emissions. In August 2006, air pollution in Lima surpassed the international standard by 122.1% The average concentration of PTS reached 166.57 micrograms per cubic meter, the international standard is 77 micrograms per cubic meter. In 2009, 1.5 tons of lead and 810 tons of
sulphur dioxide, were emitted daily, which is four times the maximum allowed under Peruvian
legislation. The Peruvian government has created an alert system for high levels of pollution. There are three levels: watch, danger and emergency. During an emergency, children, pregnant women, the elderly and the ailing may be asked to stay indoors. Those who are healthy enough to continue with their lives outside are advised to cover their mouths and noses with scarves or handkerchiefs—but not facemasks, because according to government spokesperson Carlos Rojas "people don't want images that further dramatize the situation." Also Peru is using "super tree" technology, created by
Tierra Nuestra to try and fight the air pollution in the major cities. The super tree acts like 1200 real trees, purifying the air. It sucks the outside air, and under thermodynamic pressure it combines the toxic particles in the air with water, and then pumps out clean air. Unfortunately, there are byproduct to the process, which include mud and non potable water. The Super Tree cleans approximately 200,000 cubic meters of air per day, eliminating air pollutions like
carbon dioxide. ==Water pollution==
