Concentrations and determinants of organochlorine levels among pregnant women in Eastern Spain
Persistent organic pollutants (POPs) comprise a large variety of toxic substances with ample distribution. While exposure to these toxins occurs mainly through diet, maternal POP levels may be influenced by certain sociodemographic, environmental, or lifestyle factors. This is important given that these substances may have adverse effects on fetal development. The aim of this study is to examine the sociodemographic, environmental, lifestyle, and dietary determinants of the levels of hexachlorobenzene (HCB), b-hexachlorocyclohexane (b-HCH), 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (4,4′-DDT), 1,1-dichloro-2,2-bis(4-chlorophenyl)ethylene (4,4′-DDE), and polychlorinated biphenyls (PCB co…
Prenatal and postnatal residential usage of insecticides in a multicenter birth cohort in Spain
Abstract: This study aimed to describe the residential use of insecticides in a birth cohort in Spain. Study subjects were 2 456 women enrolled into the INMA (Environment and Childhood) birth cohort followed prospectively during pregnancy and in the early postnatal period. The women were recruited at the beginning of their pregnancy between 2003 and 2008 in four regions of Spain. Socio-demographic, environmental and lifestyle information was obtained at two interviews during pregnancy, one at the first (mean:13.8 +/- 2.6 weeks of gestation) and the other at the third trimester (mean: 33.3 +/- 23 weeks of gestation). Information about prenatal use of indoor and outdoor insecticides (type, ti…
