Application

Photodissociation dynamics of 1,2-dibromopropane at 234 and 265 nm has been investigated by using velocity map ion imaging method. 1,2-Dibromopropane was used to study the effect of reductant concentration, reductant contact time and suspension pH on reductive dechlorination of carbon tetrachloride by soil manipulated with Fe(II) andHS-. It was used as internal standard during the determination of nitrogenous disinfection byproduct trichloronitromethane by gas chromatography mass spectrometry.

Biochem/physiol Actions

1,2-Dibromopropane induces hepatotoxicity and immunotoxicity in female BALB/c mice.

Based on recent results that 1,2-dibromopropane (1,2-DBP) causes hepatotoxicity and immunotoxicity in female BALB/c mice as well as a reduction of hepatic glutathione levels, the possible formation of glutathione conjugates and mercapturic acids of 1,2-DBP was investigated in vivo in

This paper described the first analytical method to simultaneously determine 14 disinfection by-products (DBPs) in meat products using microwave-assisted extraction (MAE) and static headspace (SHS) followed by gas chromatography-mass spectrometry (GC-MS). The DBPs included were 4 trihalomethanes, 7 haloacetic acids

1,2-Dibromopropane was administered orally in doses of 50-350 mg/kg to male Wistar rats. Four mercapturic acids were identified in urine by GC/MS, viz. N-acetyl-S-(2-oxopropyl)-L-cysteine (I), N-acetyl-S-(2-hydroxypropyl)-L-cysteine (II), N-acetyl-S-(1-carboxyethyl)-L-cysteine (III), and N-acetyl-S-(2-bromo-2-propenyl)-L-cysteine (IV). Mercapturic acid IV was a minor metabolite which
