From premature children to changes in DNA, dementia, loss of sleep and more likely to develop diabetes.All this brings air pollution and ... more: death.
They are not inventions or speculation.They are results of eight new studies - published only this year - on the harmful effects of pollution, so common today in many cities of the planet, Medellín included.
In the last of them, in the renowned Journal Nature, the scientists first studied the emissions in real conditions, finding high emissions of nitrous oxides in light and heavy vehicles moved with diesel, oxides that contribute to the formation of Ozone3 -superficial- and particulate material PM 2.5.
The calculation of the researchers established 38,000 premature deaths for this reason in 2015 and projected 183,000 at least by 2040.
The study was shared by NASA.
A study was presented to the American thoracic society that suggests that high pollution levels reduce good dream.Where there were more nitrous oxides (and PM 2.5 derived) for five years, the probability of having poor sleep increased 60%.
For Martha Billings, a researcher at the University of Washington, it is a sign that pollution not only affects heart and lungs, but the dream.
This month also, in the Journal of Occupational and Environmental Medicine an investigation was published that suggests that adolescents exposed to high levels of contamination by automotive traffic have specific damage in their DNA, shortening of telomeres, damage that has been associated with aging.
madness
In Translational Psychiatry, scientists from the University of Southern California presented an extensive research that suggests that in places where the standard is exceeded, women of age have an 81% greater risk of developing some form of dementia and 92% of Alzheimer's.
And if their findings are taken with the general population, air pollution would be responsible for 21% of dementia cases.
It could be due to some critical gene of Alzheimer's that interacts with dirty air.
Also, what could explain different cases, researchers at the University of Leicester published in Environmental microbiology evidence that bacteria that cause respiratory infections are affected by air pollution, increasing their infectious potential and increasing the effectiveness of antibiotic treatment.
At 3.5 years of living in neighborhoods with high levels of pollution, children may experience involvement in beta cells, which secrete insulin and maintain adequate blood sugar levels.That is, they can develop type 2 diabetes.
This study, of scientists from the University of Southern California and published in the Journal Diabetes, was made with Latin children.
Premature explosion
An investigation led by the Stockholm Institute of the Environment at the University of New YorkFine particulate, PM 2.5.The vast majority were contributed by South and Eastern.
The study was published in Environment International.
Finally, scientists from John Hopkins University found molecular and biological evidence that suggests that contaminated air exposure can cause people to keep moqueadera all year.
Studies that reinforce the effects of poor air quality on the health of thousands of people throughout the planet.
Pollution that sick.
