Thoughts
Is it that difficult to learn a foreign language? I think so. Sometimes the more we try the less is working at the moment. We'll just see the results of our effort sooner than later. The great thing is that we'll be very proud once we see it was not that complicated to overcome what in the beggining we thought was going to be impossible to achieve.

I NEED HELP WITH THIS TRANSLATION PLEASE!!! IT'S A HOMEWORK
that the contribution of the anthropogenic emissions towards the air pollution problem to a regional scale was predominant.
Anthropogenic emission sources
The main sources of air pollution with an anthropogenic origin are chimneys of the combustion facilities for generating heat and electric power, Exhaust pipes of motor vehicles and industrial processes.
Pollutants emitted by motor cars
In recent decades, car has appeared in a massive way all over the cities contributing to incrementing the air pollution problems as a consequence to the polluting gases emitted by the exhaust pipes. The main emanated pollutants by car are: Carbon monoxide (CO), Nitrogen oxides (NOx) unburned hydrocarbons (UHCs) and lead compounds.
Not all the cars emanate the same kind of pollutants and in the same proportions; these are going to depend to the kind of engine of the car. The cars which need gasoline as a fuel mainly emanate carbon monoxide, nitrogen oxides, hydrocarbons and lead compounds. The emanation of these kinds of pollutants is due to the presence in some kinds of tetraethyl lead gasoline, additive added for increase its octane rate.
The main emitted pollutants by cars which need diesel cycle engines (e.g. trucks and busses) are solid particles with soot shape which give rise to black smokes, unburned hydrocarbons, nitrogen oxides and sulfur dioxide coming from sulfur contained in the fuel.
Domestic heating
The domestic combustion facilities are the main sources of air pollution in the big cities. This kind of sources could contribute between 20 to 30 % in all the total emissions to the atmosphere in the urban areas. The main produced pollutant depends on the fuel used.
In the case of carbon the main produced pollutants are: sulfur dioxide, fly ash, soot, heavy metals and nitrogen oxide. When the fuel used is liquid (gasolio or diesel) the main pollutants emitted are: SO2, SO3, NOx, unburned volatile hydrocarbons and carbonaceous particles.
Natural gas is the cleanest fuel currently available for heating and its pollutant production is less with respect to another fuels. To a massive gas introduction for domestic heatings, replacing coal and diesel previously used,
