Urea, the compound produced by ammonia and phosphoric acid, is the main ingredient in fertilizer used to fertilize crops.
It’s the most common form of fertilizers used in Brazil.
But a study published in the British Medical Journal found that pregnant women in the state of Bahia, in southern Brazil, were significantly more likely to have a baby with Down syndrome than the general population.
The babies of the babies with Down’s syndrome were born with a birth defect known as anencephaly, the researchers said.
More than 1,300 pregnant women and children were surveyed between 2009 and 2015.
They found that the frequency of babies with congenital defects increased significantly when pregnant women used more than 30,000 pounds of fertilizer per month, up from less than 10,000 lbs.
in the general Brazilian population.
In addition to Down syndrome, researchers found that more than 500 babies with the disorder were born in Bahia.
In Bahia’s northeastern state of Paraíba, which has a population of about 14,000 people, researchers also found that birth defects were more prevalent among pregnant women who used more fertilizer than the national average.
A study of pregnant women from Bahia and the northeastern state Biafra also found evidence that babies born with Down Syndrome were more likely than the average newborn to have anencephalic development, a condition in which the brain lacks the cerebellum and spinal cord.
Bahia has the highest birth rate in the country, according to the Brazilian Institute for the Study of Human Development.
Brazil has some of the highest rates of congenital malformations in the world, with some babies born affected by congenital abnormalities and some with congenitally acquired disorders.
About 1.4 million babies are born with congenities each year in Brazil, according the World Health Organization.
