New research identifies certain chemical pollutants were related to fewer boys being born compared to girls.
And even though the SRB did not vary significantly after Hurricane Katrina in 2005, it did after the 2007 shooting at Virginia Tech, Rzhetsky and colleagues found. The SRB was lower than expected 34 weeks after the mass shooting.The researchers also found the levels of chemical pollutants"varied remarkably" across different regions of the country. For example, lead in the land was elevated in the Northeast, Southwest, and Mideastern U.S., but not in the South.
To get a more complete picture, the investigators also compared changes in the SRB to data from the U.S. National Oceanic and Atmospheric Administration, U.S. Environmental Protection Agency, Swedish Meteorological and Hydrological Institute, and Statistics Sweden.in water, and total mercury levels drove the SRB up. By comparison, lead in soil and areas with a higher renter occupancy were linked to a lower SRB, or a higher proportion of girls being born.
Several pollutants had no significant link to SRB in the study, including levels of lead or chromium in the air, arsenic in the soil, and cadmium in the air or water."The magnitude is new in terms of number of births, and the statistical methods are unusually sophisticated, but the conclusions don’t really differ from much of what has been published," says Swan, a professor of environmental medicine and public health at the Icahn School of Medicine at Mount Sinai in New York City.
