Stable carbon isotope fractionation during aerobic biodegradation of chlorinated ethenes.
Stable isotope analysis is recognized as a powerful tool for monitoring, assessing, and validating in-situ bioremediation processes. In this study, kinetic carbon isotope fractionation factors (epsilon) associated with the aerobic biodegradation of vinyl chloride (VC), cis-1,2-dichloroethylene (cDCE), and trichloroethylene (TCE) were examined. Of the three solvents, the largest fractionation ef...
متن کاملTeratogenicity of di(2-ethylhexyl) phthalate (DEHP) and di-n-butyl phthalate (DBP) in mice.
Di(2-ethylhexyl) phthalate (DEHP) and di-n-butyl phthalate (DBP) were mixed with diet at graded levels of 0.05, 0.1, 0.2. 0.4 and 1.0 wt-% and given to pregnant ICR mice throughout gestation. Maternal weight gain was suppressed and fetal resorption increased at 0.2, 0.4 and 1.0% levels of DEHP and 1.0% level of DBP. All the implanted ova died early in rats fed 0.4 and 1.0% levels of DEHP. Exter...
متن کاملStable Carbon Isotope Fractionation by Methanogens
Introduction: Methanogenic archaea, which consume CO2 and H2, have been considered models for possible life forms on Mars for a long time, even before the discovery of methane in the Martian atmosphere (1-8). Several intensive experimental studies have been conducted to investigate survivability of methanogens under conditions that approach those found on Mars (2, 3, 9). Various potential sourc...
متن کاملThyroid Disruption by Di-n-Butyl Phthalate (DBP) and Mono-n-Butyl Phthalate (MBP) in Xenopus laevis
BACKGROUND Di-n-butyl phthalate (DBP), a chemical widely used in many consumer products, is estrogenic and capable of producing seriously reproductive and developmental effects in laboratory animals. However, recent in vitro studies have shown that DBP and mono-n-butyl phthalate (MBP), the major metabolite of DBP, possessed thyroid hormone receptor (TR) antagonist activity. It is therefore impo...
متن کاملTransdermal Uptake of Diethyl Phthalate and Di(n-butyl) Phthalate Directly from Air: Experimental Verification
BACKGROUND Fundamental considerations indicate that, for certain phthalate esters, dermal absorption from air is an uptake pathway that is comparable to or greater than inhalation. Yet this pathway has not been experimentally evaluated and has been largely overlooked when assessing uptake of phthalate esters. OBJECTIVES This study investigated transdermal uptake, directly from air, of diethyl...
