Not only is the substrate and support for all living beings, but also a key factor in all our work, social and economic, and that is why if soil contamination is not very well considered, should be a matter of state policy in order to provide feasible measures and rapid implementation.

Here is a brief overview of oars what this subject, and the fundamental keys to understanding not only why the measures are applied for protection and sanitation, but also the consequences of not meeting them reliably.

Causes of Contamination

There are two basic types of generation where this is detrimental to our support, regardless of the harm caused by each component or their physicochemical properties, but are generally classified according to their origin: Read the rest of this entry »

As many know, drinking water is a nonrenewable resource, and as such, we must care for and it is a necessary good for our lives, as well as for all living things, despite the increasing water Pollution is increased by neglect, and the little care that we have about it.

Doing our bit for the issue, we have prepared a brief overview of what the issue is to gain an understanding of the various forms of pollution problems and which are now detected, and to better understand why they take certain preventive measures. Read the rest of this entry »

Caring for the environment begins at home

You just have to change old habits and apply the theory of the three Rs: reduce, reuse and recycle.

Our daily habits have much to do with the overall degradation of the planet. Acts as routine as without separating out the garbage, buy disposable utensils or purchase foods packaged in recyclable materials or environmentally damaging major contributors to environmental pollution.

Reduce
- Buy products in containers of all kinds of great ability and preferably reusable. Avoid single-use containers.
- Bring your own bags to purchase.
- Retrieve old customs such as the bag of bread, or egg cup. Read the rest of this entry »

All scientists are now confident that air pollution remains one of the main environmental problems in cities and that even current levels of pollution affecting the health of the population. The sources of polluted air we breathe day and night from various sources but the main is that given by the burning of vehicles. Traffic is primarily responsible for the urban local air pollution, caused by nitrogen oxides and suspended particles that are generated by combustion engines and other mechanical aspects of wear such as brakes or pneumatic.

The continuing contamination, daily quiet is much more severe than occasionally splashing the pages of newspapers. Supertanker accidents (Exxon Valdex, Aegean …), industrial plants (plant biocide of multinational Union Carbide in Bhopal, India) are small when compared with the amounts of pollutants are discharged annually by industrialized country.

These are the six pillars on which rests the entire industrial economy and therefore the main sources of the pollutants described above. The data relating to Spain, from official estimates of the decade 80-89.

- Oil refining
Ten establishments that have occurred over the decade an average of 36 million tons. This has an energy expenditure of 1.5 million megawatts, damaging 360 million m3 of water per year (almost 8 times the annual flow of the river Manzanares), emitted into the atmosphere 150,000 tons of anhydrous sulfuric acid and 17,000 of nitrogen oxides ( equivalent to 19 tons of pollution every year in hours). Do not forget that the fate of the production of this sector is also polluting: the burning of oil multiplied by hundreds atmospheric corrosion. Read the rest of this entry »

These are the substances most important pollutants because of their greater volume or greater toxicity.

Classical pollutants:

- Carbon dioxide (CO2): The main gas responsible for global warming.

- Nitrogen oxides (NOx) contribute to the formation of ground level ozone and smog.

- Hydrogen chloride (HCl): Very soluble in water, forms a very strong acid called hydrochloric acid, responsible for the formation of acid mists in environmental conditions of humidity and for investments. Such a situation may cause irritation of eyes and other sensitive human tissues and respiratory problems.

- Sulphur dioxide (SO2): Principal responsible for the destruction of almost one third of the forests of central and northern Europe by acid rain. Read the rest of this entry »

Pollution

Pollution and toxic waste are a poorly understood aspect of progress. Human beings do not realize the magnitude of the problem. Live every day with thousands of chemicals that reach him through the water, air, land and the products they consume. Currently, there are between 80,000 and 120,000 synthetic chemicals in production and released into the market an average of 3 new synthetic chemicals per day. There is very little information about many of these compounds and their impact on the environment and health of people.

The emission to the environment of these substances pose a serious risk to life. Every newborn has on your body and contaminants in the environment by human activity. The continuing contamination, daily quiet is much more severe than occasionally splashing the pages of newspapers. Accidents Valdex-Exxon supertankers, Aegean Sea, Prestige …-, of industrial-plant biocide of multinational Union Carbide in Bhopal, India, remain small when compared with the amounts of pollutants are discharged annually worldwide.

In big cities and in the vicinity of the high density of population and industry causes air pollution, usually from combustion processes such as automobile engines, is very high. Among the pollutants are nitrogen oxides. And these are very reactive, for example when reacting with oxygen in the air

NO (g) + O2 (g) —-> NO2 (g)

turn nitrogen dioxide by the action of sunlight, it decomposes into carbon monoxide

NO2 (g) + light —-> NO (g) + O (g) Read the rest of this entry »

Ozone is present naturally in the troposphere. One part comes from that in the upper atmosphere (stratosphere) which is transported to lower levels, the air layers near the surface. Another part comes from natural processes that take place in the biosphere and that lead to the formation of ozone from nitrogen oxides emissions that are caused by biological processes and the emission of volatile organic compounds from vegetation, fermentation processes or volcanoes.

Ozone amounts that give rise to these processes are small and their concentration in the air does not reach dangerous levels. However, tropospheric ozone can be a problem when it causes an increase in concentration by artificial means: pollution. Many activities performed by the man now emit air pollutants that are precursors of ozone. By the action of sunlight, these chemicals react and cause the formation of ozone. This usually occurs mainly in large cities, the process favored by high concentrations of pollutants in the air. Read the rest of this entry »
