Los Clorofluorocarbonados (CFCs)

Los Clorofluorocarbonados (CFC) y sus derivados tienen como fuentes principales algunos productos industriales, y los óxidos de nitrógeno, que se producen por multitud de causas, principalmente por la quema de combustibles fósiles y la utilización de fertilizantes químicos.

La producción de cloro-fluoro-carbonos [CFCs] contribuye con aproximadamente el 14% del efecto invernadero. Los CFCs son sustancias químicas sintéticas, formadas por cloro, flúor y carbono. Las moléculas de CFC tienen una larga vida activa. El CFC-1 1 es activo durante unos 65 años y el CFC-12 durante unos 110 arios. Cada molécula de CFC-11 y de CFC-12 contribuye 3.500 y 7.300 veces más, respectivamente, al efecto invernadero que cada molécula de C02.

Los CFCs también destruyen la capa de ozono en la estratosfera, causando que una mayor proporción de rayos ultravioleta alcance la superficie de la tierra.
Una mayor incidencia de rayos ultravioleta tendría importantes efectos tanto en la agricultura como en la salud humana. E1 cáncer en la piel, los problemas oculares, y las afecciones al sistema inmunológico, son las amenazas más inminentes sobre la salud de la población humana. Podrían también presentarse efectos adversos sobre las algas y el plancton, bases de la cadena alimentaria en el mar

Eliminación de los CFC de los inhaladores - dosificadores

1) OBJETIVO
Elaborar una estrategia comunitaria para la eliminación de los clorofluorocarbonos (CFC) de los inhaladores - dosificadores.
2) MEDIDA DE LA COMUNIDAD
Comunicación de la Comisión al Parlamento Europeo y al Consejo de 23 de octubre de 1998: Eliminación progresiva de los CFC de los inhaladores - dosificadores.
3) CONTENIDO
Los CFC forman parte de las sustancias que debilitan la capa de ozono y cuya producción y consumo se prohibieron en la Comunidad en 1995. No obstante, siguen utilizándose en los inhaladores - dosificadores destinados al tratamiento del asma y de las bronconeumopatías crónicas obstructivas (BPCO) en virtud de las excepciones previstas en el Protocolo de Montreal y en el Reglamento (CE) nº 3093/94 para sus usos esenciales.
En la decisión IX/19 del Protocolo de Montreal, la Comunidad Europea y las demás Partes del Protocolo acordaron presentar, antes del 31 de enero de 1999, una estrategia de transición para la eliminación de los CFC de los inhaladores - dosificadores. La Comisión cumple con tal compromiso mediante la adopción de esta Comunicación, que recomienda medidas que deberían adoptar los Estados miembros para facilitar la transición hacia tratamientos del asma sin CFC preservando la salud y la seguridad de los pacientes.

  • The Economic and Governmental Sides of Legalized Abortion

    At first thought, abortion may not appear to have any involvement in economics. But, economics and abortion are, in fact, deeply intertwined. Studies of abortion show that financial hardship is the reason most often cited by women seeking abortions. Lack of money is rarely the only reason a woman seeks an abortion. Most women do so for a complex set of reasons, but money is frequently the paramount factor, the one that tips the scales in favor of abortion. This is especially true for low-income families and single

  • The Effects of Snuff Use on the Body’s Health

    857 Words  | 2 Pages

    The use of snuff is widespread in the recent years, especially among male adolescents and young adults. Snuff was first introduced in Europe in the 17th century and it was inhaled through the nostrils in dry form, but nowadays most snuff is moist and taken orally (Asplund, 2002). Snuff use, as an issue, has been a great concern to many researchers. A handful of studies have been conducted in this area to find out the factors that may contribute to such a phenomenon as well as to identify its impact on the body’s health. Snuff users are at risk of many diseases such as heart disease, blood pressure and cardiovascular diseases (Asplund, K, 2001; & Wickholm, Galanti, Soder, & Gilljam, 2003). On the other hand, many researchers have investigated the difference between snuff’s and Cigarettes’ effects on the health of the body. This literature review aims to shed light on the effects of snuff use on the body’s health. It is divided into two sections, the first of which deals with the effects of snuff use, and the second one is about the difference between cigarettes’ and snuff’s effects on the health of the body ( Wickholm , Galanti, Soder, & Gilljam, 2003).

  • Abortion: Murder after 20 weeks

    1492 Words  | 3 Pages

    ...aby has still been born alive where it is usually left unattended to die. Prostaglandin Chemical Abortion is a form of abortion after 20 weeks where doctors use chemicals that cause the mother’s uterus to contract to produce intense contractions. The contractions are much more violent then normal and will decapitate and kill the fetus. The last form of abortion after 20 weeks is, Hysterotomy or Caesaerean Section, in which the surgeon cuts through the abdomen and then cuts the umbilical cord. Once the umbilical cord is cut, the oxygen supply to the fetus is gone and the fetus suffocates. Sometimes, the fetus is born alive, but it is left in a corner to die. Although the abortion process provides pregnant women with an alternative option, after twenty weeks, due to the emotional and sensory growth of the fetus, it would be cruel and unethical to have an abortion.

Depending upon the dosage, the user may feel a slight stimulation, less inhibition, or lose consciousness altogether. There is also something called Sudden Sniffing Death Syndrome. This means that the user can die after one inhalant use or after many. Immediate effects inhalants offer are nausea, sneezing, coughing, nosebleeds, feeling/looking tired, bad breath, lack of coordination, and loss of appetite. There is considerable damage to ones heart, kidney, brain, liver, bone marrow, and other organs.

  • Abortion in the United States: Rights and Restrictions

    1364 Words  | 3 Pages

Wade was a supreme court case that allowed women to have an abortion because it was a woman 's right to her own privacy. After this supreme court case, they made restriction on abortion. According to Abortion Procedures During First, Second and Third Trimester (2016) , in some states women can’t have an abortion after her third trimester or when the baby can survive outside the womb.

Abortions have become more and more common. We have become insensitive toward abortion and

  • Fossil Fuels vs. Renewable Energy

    1889 Words  | 4 Pages

    Over the last two centuries, humanity has become increasingly reliant on fossil fuels. Over that time, the consequences of constantly burning fossil fuels have accumulated into a threat to industrialized cities. The burning of fossil fuels causes acid rain to shower on cities and ecosystems around the world, tormenting their inhabitants. The increasingly deadly pollution caused by the burning of fossil fuels has caused the deaths of many people around the world by causing respiratory problems. Not only has the pollution worsened, but the supply of fossil fuels is not limitless – as humanity’s reliance increases the supply decreases, and that is all the more reason to break humanity’s reliance on fossil fuels. Fossil fuels should be replaced with cleaner alternatives because fossil fuels cause environmental hazards, are non-renewable, and are detrimental to human health.
