Quimicando com a Ciência - Chemistring with Science

Attitudes, chemical reactions and imbalance

The development of new technologies to meet the way of life of the human being has entailed an unbridled process in the name of progress governed by capital. Pragmatics which lasted for many years in order to generate income without measuring their effects on the environment and consequently to our health today is seen in the imbalance of numerous natural ecosystems, the extinction of endemic species and the temperature increase in microclimates, for instance.

How has happened the increase rate of gas in the atmosphere?

The high rate of toxic gases is explained by the large-scale production promoted by the chemical industry, which is the basis to meet the demand of products consumed daily (such as medicines, food, packaging, energy, etc.). We can also list the great burning of fossil fuels in civil transportation, the aspects of logistics to distribute industrial products, and as the most aggravating factor the deforestation and pollution of the oceans, it is impossible to recycle these gases, occurring an accumulation in the troposphere and stratosphere.

Are there any consequences for the climate?
The increase in levels of ultraviolet radiation resulting from the increase of these gases, including CFCs *, which produce free radicals which react in the atmosphere with O3 (ozone) responsible for blocking solar radiation.

O₃    +   X_{°    ßà}   OX   +  O₂

Thus the emission of gases creates an imbalance in the cycle of ozone formation, increasing the incidence of UV-B and temperature in microclimates.

And what about the liquids waste?

The waste produced by industries and from sewage are often disposed improperly, these species are not natural and they are dumped into rivers, lakes and dams causing an accumulation of substances that are not part of biogeochemical cycles that already exist, which causes an imbalance and increased the number of infectious diseases and ecologies in bodies of water. (Basic Sanitation).

How can we reverse the situation?

To analyze, explain and reverse processes such as elevated UV-B radiation, high concentrations of toxic gases and the increase of diseases is necessary different areas of knowledge (engineering, sociology, chemistry, pharmacy, biology) correlate with the focus on Production and Conscious Consumption and seek new methodologies that impact less and preserve more our health and our ENVIRONMENT.
