ENVIRONMENTAL POLLUTION
According to data from the National Emissions Inventory, in 1999 Mexicans were broadcasting 40.5millones tons of pollutants into the atmosphere, of which 58% were emitted bynatural sources (soil, vegetation and volcanic activity), and 42% for activities human.
Most of emissions from human activities were generated by vehicles and other uses of fuels and the electricitygeneration plants.
In Mexico, the generation of air pollutants is higher in the State of Mexico, Veracruz, Jalisco and Mexico City, with an average of between 6.4% and 9.4% of national emissionsfrom human activities.
In contrast, Baja California Sur, Quintana Roo, Nayarit, Tlaxcala and Aguascalientes emitted less of 1% of the national total.
It is estimated that every Mexican emits on averageabout 170kilogramos of air pollutants per year, equivalent to the weight of two adults.
To give an idea of the level of air pollution in Mexico using the Metropolitan Index of Air Quality (IMECA),this consists of a transformation of pollutant concentrations to a dimensional number
The IMECA aims to inform the public in a clear, timely and continuous on air pollution levels, the likely damageto health and the protective measures to take. Based on the values ​​of IMECA, authorities can declare an environmental emergency.
What is being done to prevent contamination?
In the Ministry ofEnvironment and Natural Resources (SEMARNAT), created a program called Pro Air, which seeks to reduce pollutants in the main cities.
This is decreasing from different sources, stationary, ie facilitieselectrical or oil, and mobile, which are mainly of transport.
What is the biggest risk we are facing today?
A disease because air pollution
What is it that produces more greenhouse pollution to theatmosphere?
Most of it is emitted from natural sources such as volcanic activity, soil and vegetation.
