Still seriously concerned about the harmful impact of polluted environment on the human body, scientists, in particular the American, came to the conclusion that newborns born in the most polluted cities of the most impure state of California, on average, weigh less than those born in more " Pure "states and cities. The study was conducted in Los Angeles and New York, the most polluted metropolitan areas of the United States.

Such results were obtained after analysis of several independent studies of the hazardous effects of dense microparticles polluting the environment. This is a kind of microscopic soot and dust, which in adults can cause a heart attack and a decrease in respiratory capacity of the lungs.

In this case, it does not concern anyone but our children, and one of the possible solutions is the introduction of more stringent regulations for diesel equipment in ports, and the modernization of engines on trucks and trains. Solid particles are formed from microscopic dust particles and small droplets that are in the exhaust gases of motor vehicles, in soot during the combustion of diesel fuel, in boiler rooms, as a result of the operation of industrial chemical plants. These grains can be highly toxic and deeply settle in the tissues of the lungs.

During the work carried out in 2000, 18,000 newborns from California were examined. Scientists evaluated the birth weight and the concentration of microparticles in the air in the area where the mother's mother lived the last 9 months. It was found that in mothers living in the most contaminated areas, the weight of newborns, on average, is less by 100 g than those living in relatively clean areas. The authors of the study believe that this lost weight would be very suitable for a newborn, and, in addition, the weight at birth, in many respects testifies to the general state of health.

So far, scientists can not determine how the contamination of the environment affects the child, possibly indirectly impairing the health of the mother, or there is a direct negative effect of dust particles on the fetus.

It would seem that this difference of 100 g is not so significant and may not play a role in the development and growth of the child, however, low birth weight is almost always associated with health problems in the future. Currently, a study is being planned to identify the long-term consequences of this phenomenon on health.
