(Table 1) Concentrations of phthalates in chloroform extracts from waters of the Northwest Indian Ocean and the Red Sea
1984
Smirnov, M B | Smirnov, B A
Chloroform extracts of water-soluble organic matter collected in the water column from the surface to the bottom were studied by C-13 and H-1 NMR chromatographic mass spectrometry, and phthalate concentrations were determined by capillary gas-liquid chromatography. More than 14 compounds were found including diethyl phthalate, ethyl butyl phthalate, dibutyl phthalate, and di-2-ethylhexyl phthalate, phthalates with normal C4-C12 chains, phthalates partially esterified with methanol, and others, at total concentrations up to 0.4 mg/l. Possible reasons for presence of phthalates in oceans, sometimes in high concentrations, are discussed.
