The most harmful particulate<br />

materials are the ones equal or smaller<br />

than 25 m g/m3 However, the<br />

available information allows for the<br />

estimate of emissions of particulate<br />

materials that are equal or larger then<br />

10 m g/m3 Studies carried out by the<br />

World Bank present the 15 most<br />

problematic municipalities in terms of<br />

particulate material emission, as<br />

shown in Table 11<br />

The limited information prevents the<br />

measurement of how serious the<br />

atmosphere pollution registered in<br />

large centres is, particularly in the<br />

South and Southeast regions of the<br />

country In these cases, the emissions<br />

of nitrogen oxides, hydrocarbons,<br />

carbon monoxides and aldehydes<br />
