Alarm your child's IQ

An American study demonstrated that children whose mothers were exposed to a high PAH environment had an overall IQ index and low language IQ.

Polluted environment PAH is an environment with a high content of popycyclic aromatic hydrocarbon (PAH) exceeding the regulated standard. PAH pollution is caused by burning coal , petroleum and other organic substances and discharging it into the atmosphere . Their content is considered high when above 2.26 nanograms / cubic meter (ng / m ³ ).

The work of the National Institute of Environmental Health, the Department of Environmental Protection and a number of private donor organizations has demonstrated: children whose mothers are exposed to excess PAH standards in New York, will have indicators intelligent IQ and speech IQ were lower than those of children, but when pregnant, mothers were exposed to subprime PAH, from 4.31 to 4.67 points.

Children are much affected by the environment.

The difference between the above 4 points on IQ for education is very significant, it reflects through standardized tests in terms of knowledge acquisition. However, researchers also point out that this effect may vary with each individual.

249 children in the age of 5 from different backgrounds were tested and scored IQ scores, behavioral IQ and overall IQ.

" The study of the inverse correlation between actual PAH levels in many cities and the IQ of children exposed as fetuses in the womb is an emergency alarm for all. " We need to find ways to prevent pollution from affecting the intelligence of future generations ," said Linda Birnbaum, director of the National Institute of Environmental Health.

The mother when she is pregnant always wears an air quality recorder. Researchers have developed models to examine the relationship between exposure to PAHs and IQ, taking into account other factors such as secondhand smoke exposure, lead concentration, and process exposure. mother's cultural level, quality of family care .

The lead author of the study, Frederica P. Perera, professor of the School of Public Health at Coumbia University and the director of the Institute of Environmental Health of children, said: " The level of overall IQ reduction here is equivalent. With low concentrations of lead exposure, this finding should be considered. IQ is an important predictor of children's education and PAH is a common pollutant in the world-wide urban environment. " .

Fortunately, PAH pollution is something that can be actively controlled through control checks, along with the replacement with clean energy sources and policy intervention.
