UGA scientist to study effect of air quality on unborn babies

A pregnant woman walks down the street of a large city. She doesn't know it, but the air she's breathing could be hurting her unborn baby.

From recent studies in many countries, scientists suspect a relationship between exposure to air pollution and health problems like preterm births, low birth weights, poor fetal development and mortality, said Luke Naeher, an environmental epidemiologist with the University of Georgia College of Agricultural and Environmental Sciences.

Scientists know the air pollution in large cities can aggravate or cause health problems in children and adults. But how can it affect a baby inside a mother's womb? Naeher wants to answer this question.

In the summer of 2002, Naeher studied the personal air pollution exposure of 45 pregnant women in Trujillo, Peru. His co-investigator was Manuel Aguilar Villalobos, director of the Asociacion de Aire Ambient in Lima, Peru.

Based on this research, the American Chemistry Council has awarded Naeher a $100,000 grant to expand his research in Trujillo.

Naeher will measure the personal pollution exposure of 100 pregnant Trujillo women (50 from urban and 50 from rural areas) during their pregnancies.

He and his team will measure air pollution levels inside the homes of the pregnant women and at one urban and one rural site. The team will collect blood and urine samples from the women during their pregnancies and postdeliveries. And they'll collect samples of meconium, a baby's first feces, and umbilical cord blood from the newborns. The Centers for Disease Control and Prevention will analyze the samples.

"This study will help us understand the magnitude and potential impact of prenatal exposure to a range of environmental pollutants," Naeher said.

Trujillo is a city of about 750,000 people in a developing country. It has higher levels of air pollution than most U.S. cities. Peruvian standards and regulations on vehicle emissions, the leading ca
