The character of the pollution The character of the pollution of the waterof the water• The terms(ends) pollution of the The terms(ends) pollution of the

water and pollution of the air water and pollution of the air involve both the presence of involve both the presence of strange undesirable matter in a strange undesirable matter in a substance, for the rest, "pure" or substance, for the rest, "pure" or "natural"."natural".

• Nevertheless, the concept of the Nevertheless, the concept of the pure water is very different from pure water is very different from that of pure air. As we saw in the that of pure air. As we saw in the previous topic, the air is a previous topic, the air is a mixture(mixing) of diverse mixture(mixing) of diverse components, and the " pure air " is components, and the " pure air " is considered to be, consequently, a considered to be, consequently, a particular mixture(mixing) that particular mixture(mixing) that represents a species(kind) of represents a species(kind) of terrestrial ideal atmosphere.terrestrial ideal atmosphere.

• The spillages that come directly to the sea contain toxic substances that the marine The spillages that come directly to the sea contain toxic substances that the marine organisms(organisations) absorb of immediate form. In addition they form important warehouses organisms(organisations) absorb of immediate form. In addition they form important warehouses in the rivers that suppose in turn an enormous development of new pollutant elements and an in the rivers that suppose in turn an enormous development of new pollutant elements and an excessive growth of undesirable organisms(organisations). These warehouses come from the excessive growth of undesirable organisms(organisations). These warehouses come from the stations filter systems, of the residues of dredgings (specially in the ports and estuaries), of the stations filter systems, of the residues of dredgings (specially in the ports and estuaries), of the graveras, of the arid ones, as well as from a great variety of toxic organic and chemical graveras, of the arid ones, as well as from a great variety of toxic organic and chemical substances.substances.

The most spectacular cases of pollution for important reason of pollution of the coasts. The most spectacular cases of pollution for raw(unripe) are in the habit of being at the expense of the superoils used to transport them, but raw(unripe) are in the habit of being at the expense of the superoils used to transport them, but there are other many ships that spill also oil, and the exploitation of the petriliferous marine there are other many ships that spill also oil, and the exploitation of the petriliferous marine platforms supposes also an important contribution of spillages. It thinks that of every million platforms supposes also an important contribution of spillages. It thinks that of every million embarked tons of crude oil a ton is spilt. Between the major black tides registered up to the embarked tons of crude oil a ton is spilt. Between the major black tides registered up to the moment they find the produced one for the petroleum Amoco Cádiz opposite to the French moment they find the produced one for the petroleum Amoco Cádiz opposite to the French coasts in 1978 (1,6 million barrels of crude oil) and the produced one for the petriliferous well coasts in 1978 (1,6 million barrels of crude oil) and the produced one for the petriliferous well Ixtoc I in the gulf of Mexico in 1979 (3,3 million barrels). The spillage of 240.000 barrels for the Ixtoc I in the gulf of Mexico in 1979 (3,3 million barrels). The spillage of 240.000 barrels for the petroleum Expón Valdez in the Princ.

The potabilizacion of the water The potabilizacion of the water of seaof sea • Other one of the practical applications of the solar power is the water Other one of the practical applications of the solar power is the water

potabilización. By means of the diverse variants of this technology it is potabilización. By means of the diverse variants of this technology it is possible to produce drinkable water from contaminated water. This can be possible to produce drinkable water from contaminated water. This can be achieved by means of relatively simple technology, this application turns out achieved by means of relatively simple technology, this application turns out to be specially useful for regions removed from the comforts of the to be specially useful for regions removed from the comforts of the civilization, as islands and coastal little communicated regions. But also they civilization, as islands and coastal little communicated regions.

• Depending on the degree of pollution that contains the water, diverse solar Depending on the degree of pollution that contains the water, diverse solar technologies exist for his purification. In general, the solar systems for the technologies exist for his purification. In general, the solar systems for the water purification are capable of removing only relatively small quantities of water purification are capable of removing only relatively small quantities of pollution, with exception probably, of that they are in use for purifying water pollution, with exception probably, of that they are in use for purifying water of sea. The solar distillers, so, are not adapted to purify either black waters of sea. The solar distillers, so, are not adapted to purify either black waters or industrial residues. There are adapted for potabilizar superficial waters , or industrial residues. There are adapted for potabilizar superficial waters , underground waters or water of sea. Basically there would be necessary to underground waters or water of sea. Basically there would be necessary to consider two levels of pollution for which are suitable: 1) Water Waters down consider two levels of pollution for which are suitable: 1) Water Waters down with microbial light pollution and 2) with pollution of you go out disueltas. with microbial light pollution and 2) with pollution of you go out disueltas.
