Buenos Aires, Argentine has high levels of carbon monoxide in the air: up to 14 ppm, whereas the WHO’s authorized limits don’t exceed 9 ppm. For every vehicle on the road, the atmosphere will receive 200 kilos of nitric oxide, 400 kilos de hydrocarburs and 3000 kilos of carbon dioxide. There are an estimate of 4 million units on the streets of Buenos Aires every week, which gives a better idea of the magnitude of the problem. |
