Organochlorine compounds and concentrations of thyroid stimulating hormone in newborns.
AIMS To assess the association between prenatal exposure to organochlorine compounds and thyroid status in newborns from an area with high levels of hexachlorobenzene (HCB). METHODS A total of 98 mother-infant pairs (83.1% of all children born during the period 1997-99 in a specific area polluted with HCB) were recruited. Levels of organochlorine compounds were measured in 70 cord serum sampl...
متن کاملReactions of aqueous chlorine and chlorine dioxide with model food compounds.
Chlorine and chlorine dioxide (ClO2), common disinfecting and bleaching chemicals used in the food industry, are potent oxidizing and chlorinating agents. Unfortunately, little is known about the nature of the reactions of chlorine with organic food constituents. This presentation reviews published information concerning the reactions of chlorine gas (Cl2[g]), aqueous chlorine, and ClO2 with mo...
متن کاملUptake and excretion of organochlorine compounds in neonatal calves.
Intestinal absorption mechanisms of young calves change rapidly during the first 24 h postpartum and subsequently effect the absorption efficiencies of a wide range of compounds. This study was conducted to determine absorption efficiencies of (p,p'-dichlorodiphenyl)dichloroethylene (DDE), 2,2',4,4',5,5'-hexachlorobiphenyl (PCB-153), and 1,2,3,4,6,7,8,9-octachlorodibenzo-p-dioxin (OCDD) when ad...
متن کاملLymphatic and portal vein absorption of organochlorine compounds in rats.
The route of absorption of ingested compounds is a determinant of their distribution and metabolism. Portal vein absorption results in direct transport to the liver, where metabolism may take place before extrahepatic delivery. Lymphatic absorption can result in delivery of parent compound to nonhepatic tissues. Understanding the fate of an ingested compound requires determination of the import...
متن کاملBreastfeeding, exposure to organochlorine compounds, and neurodevelopment in infants.
OBJECTIVE Exposure to organochlorine compounds (OCs) occurs both in utero and through breastfeeding. Levels of hexachlorobenzene (HCB) found in the cord serum of newborns from a population located in the vicinity of an electrochemical factory in Spain were among the highest ever reported. We studied the association between exposure to OCs and breastfeeding on neurodevelopment in the 1-year-old ...
