Tests performed on amniotic fluid reveal prenatal exposure to toxic agents.
2004 JAN 1 - (NewsRx.com & NewsRx.net) -- Tests performed on amniotic fluid reveal prenatal exposure to toxic agents.
"Prenatal pesticide exposures may adversely affect children's health. However, exposure and health research is hampered by the lack of reliable fetal exposure data. No studies have been published that report measurements of commonly used nonpersistent pesticides in human amniotic fluid, although recent studies of pesticides in urine from pregnant women and in meconium indicate that fetuses are exposed to these chemicals," researchers in the United States report.
"Amniotic fluid collected during amniocentesis is the only medium available to characterize direct fetal exposures early in pregnancy (approximately 18 weeks of gestation). As a first step in validating this exposure biomarker, we collected 100 amniotic fluid samples slated for disposal and evaluated analytical methods to measure organophosphate and carbamate pesticides and metabolites, synthetic pyrethroid metabolites, herbicides, and chlorinated phenolic compounds," described A. Bradman and colleagues, University of California Berkeley, School of Public Health.
"The following six phenols were detected (detection frequency): 1- and 2-naphthol (70%), 2,5-dichlorophenol (55%), carbofuranphenol (5%), ortho-phenylphenol (30%), and pentachlorophenol (15%), with geometric mean concentrations of 0.72, 0.39, 0.12, 0.13, and 0.23 microgram/L, respectively, for positive values. The organophosphate metabolites diethylphosphate and dimethylphosphate ...
