The smell of tiger can be fatal to enter into a stuffy room, but the World Health Organization goes to show that thousands of millions of people live in rooms with excessive levels of pollutant concentration and this contributes to disease development, with outcome or death.
The pollution is composed of many types of gases, droplets and particles that reduce air quality and good to know that it can be contaminated both the city and the countryside, where there may be such an excess of reagent nitróno. Main contaminating factor is the proliferation of transportation, but also the air quality within million homes, typically by burning used for cooking or heating.
The objective of the UN study seeks to show differences to highlight cities with more effort and encourage the rest safe to take steps, experts say. Spain and Italy exceeds 50% limit recommended by WHO microorganisms (20μg per meter cúbido) and are the Western European countries worst air they breathe. Worldwide, Botswana and Mongolia also have the uncertain privilege, exceeding ten times the limit.
How many diseases develops the air we breathe? Pollution makes the body vulnerable, as is known, colds, eye infections and allergic diseases. But a hundred scientists from 14 countries now seem to show who is responsible for 1.3 million deaths annually and that reduced the level of large particles (PM10) and small (PM2, 5), in the air we breathe, could be avoided over a million of these.
Underdevelopment is directly linked to the worst air quality and states with massive population and limited development, such as China and India, still use mostly coal to generate electricity. The development however, as seen in Scandinavia, improves air quality and health of the population, especially by public transport and renewable energies.
The global report has sought to know more environmental factors that damage the health and raise awareness of measures that, if followed, could prevent millions of deaths. Experts objections that few cities follow strictly the recommendations of WHO and Egypt, Bangladesh, Bosnia-Herzegovina, India, Kuwait, Nepal, Nigeria, Pakistan, Saudi Arabia, Senegal, United Arab Emirates and Iran are above 100μg / m3.
Spain has in Zaragoza and Granada the worst example breathable, with 45 and 40 mg/m3 respectively, and has its cleanest air in Santiago de Compostela (18μg/m3) and Logroño (18μg/m3), but is far behind France, Germany, Denmark, Austria and the UK. It also exceeds by 33% the concentration limit of smaller particles with an average of 12.9 ug/m3, from a peak of 10μg/m3 recommended.
The report recognizes that developed countries have advanced since banned the factories in the cities and regulated the traffic and fuel, but with an unstoppable incremental concentration of population in urban centers, we see that in the future health generally will depend on how they are designed cities as primary prevention: The encouragement of public transport and walking, reduce pollution and respiratory diseases such as asthma or cancer, and reduce cardiovascular disease by more exercise.
The pollution can irritate the eyes, throat and lungs. The burning eyes, coughing and chest tightness are common to overexposure and has established a clear relationship between the level of pollution and the number of hospitalizations for two diseases at high risk for death and venous thrombosis pulmonary embolism.
People with heart disease such as angina, or lung disease such as emphysema or asthma, can be very sensitive and see their condition worsen to have to limit their activities. Children feel the effects at lower levels than adults and as a result experience more illness such as bronchitis and earaches.
What's in the air?

- Carbon monoxide is the most harmful, causing vomiting, dizziness, reduced reflexes and visual acuity.
- Bronchitis, pneumonia, emphysema, cardiovascular diseases and allergies, some types of cancer related to benzene and, in extreme cases, anencephaly (absence or atrophy of the brain in newborns) in cities with high air pollution index, as Cubatão ( SP) and Araucaria (PR), until not long ago.
- Nitrogen dioxide causes sore throats, cough, shortness of breath, pulmonary emphysema and allergies.
- Lead affects the nervous system (convulsions and reduced learning in children), renal system, circulatory and reproductive systems.
- The coarse particles dirty streets and roofs, reduce the absorption of sunlight, reduce visibility and cause corrosion in metals. The finest particles, called aerosols, penetrate into the respiratory system, leading to asthma and heart disease.
- When it rains, this mixture of gases and particles is taken to the ground, rivers and lakes, altering the health of plants and animals.
- The emission of these pollutants is also related to the reduction of the layer of ozone, acid rain and the greenhouse effect, all this together, encouraged one of the biggest headaches of all the environmentalists on the planet.
