hazardous 9/11 dust made newborn babies smaller - air cleaner

Fifteen years after the collapse of the World Trade Center in New York City, researchers are still studying how the September 11, 2001 terrorist attacks affected people's health.
When the Twin Towers landed at 9/11, a mass of hazardous substances hung over the surrounding blocks, covering everything, and everyone was exposed to them for a few days.
According to a new study, these dust clouds could lead to negative birth outcomes for mothers in lower Manhattan. (

This study adds a study that suggests that air pollution exposed to the uterus can have adverse effects on the health of newborns, which may play a role throughout their lifetime.
The study, published in the Journal of Human Resources fall 2016, researchers Hannes Schwandt and Janet Currie studied the birth records of New York City from 1994 to 2004. Of those 1.
When 2 million babies were born, they separated the data from women living in lower Manhattan, so the women exposed to dust clouds were the most.
The team then improved the search for women who had previously had babies to better determine if the low birth weight was abnormal.
They found that women in the first three months of pregnancy during the 9/11 period were more than twice as likely to be born prematurely as they were.
The number of babies with low birth weight has also increased, which may lead to later problems such as diabetes, heart disease and higher risk of elevated blood pressure.
Pregnancy status is very important for future economic outcomes and long term
The term "human development and economic success", says Schwandt, an economist at the University of Zurich, whose research focuses on children's development.
Low birth in addition to health risks-
Life-long earnings of weight babies tend to decrease.
Another potential factor for 9/11 mothers may be after
Like air pollution, trauma stress disorders are associated with low birth weight.
However, after comparing stress levels across the city, the researchers were able to exclude post-traumatic depression as a mixed factor for birth in their study.
Instead, they believe the dust cloud is the culprit.
Firefighters work under the rubble of World Trade Center 9/11.
The findings of this study are amazing because many affected women live wellto-
Communities that often tend to have better birth outcomes.
In the United States, poor communities tend to experience pollution and low birth weight.
In this case, we have these relatively wealthy mothers, and then they will be affected, and we see that the extent of this effect is similar to the difference between the dominant mother and the weak mother, schwandt said.
So we can imagine it as the dominant mother exposed to the dust cloud in southern Manhattan, with similar birth outcomes to the vulnerable mother who was not exposed.
Previous studies of 9/11 infants showed little evidence of this effect.
But Schwandt said the studies either took data from specific hospitals or from various corners of the city, including poorer, more polluted areas such as the South Bronx.
Because in some parts of New York City, the rate of premature birth is very high, which changes the data set.
On the whole, these numbers are comparable to what you see in vulnerable countries.
The study has implications for cities around the world that struggle with polluted air, such as New Delhi, Mexico City and Beijing. (

Most other studies that study the effects of air pollution on birth outcomes often examine experiences that occur for a long time.
Because terrorist attacks occur in a closed time and space, researchers can better understand the impact of the resulting pollution.
Basically, this is the closest to the controlled environment because they might get 9/11 dust clouds, which both simplifies the variables and enlarges the changes.
A similar study was conducted in Beijing, when it tried to clean its famous polluted air before and during the 2008 Olympic Games.
On December 21, 2016, during the "red warning" of Beijing's air pollution, people wore masks when walking in the smog air.
In Beijing, air pollution levels fell during the Olympics and then picked up again as they relaxed all controls that had been put in place, the study said
The author, Tracey woodway, a researcher at the University of California, San Francisco.
Research in Beijing found that during a cleaner period of air, babies being bred weighed about 23 grams more than babies born in the same period of the previous year, when air pollution was more serious.
Currently, Schwandt and Currie don't plan to go on and see how the health and economic fate of 9/11 babies developed in their teens.
But they say their work is in itself an example of the exposure of air pollution.
That's why this kind of disaster research is useful in a sense, not because it's very representative in general, but because it allows you to identify the effects of pollution, schwandt said.
Just like opening, closing.
