“…This means that this relatively nonpolar compound (with an octanol/water partition coefficient of about 10,000; Muir, 1984) can be removed by biosorption to a significantly higher degree than the mean of all organics contained in the wastewater. This is in good accordance with results of Dobbs et al (1989) who found sorption of organics to mixed-liquor solids to be correlated well with the octanol/water partition coefficients of the organics.…”

“…Concentrations of phosphoric acid tributyl ester in fish in different rivers are reported to be in a range of 2 to 26 ng/g (Muir, 1984). In river waters, phosphoric acid tributyl ester concentrations of 10 ng/1 to up to 10 ug/1 were measured during the 1970's (Muir, 1984).…”

“…In river waters, phosphoric acid tributyl ester concentrations of 10 ng/1 to up to 10 ug/1 were measured during the 1970's (Muir, 1984). Although phosphoric acid tributyl ester is biodegradable (Muir, 1984), it has also been detected in a biologically treated oil reclaiming wastewater (Gulyas et al, 1994a).…”

“…Cascieri et al (1985) found hyperplasia of the bladder epithelium in rats after daily administration of food containing phosphoric acid tributyl ester in concentrations of up to 5000 ppm for 13 weeks. Phosphoric acid tributyl ester is accumulated in fish (bioconcentration factor of 7 in Goldfish and 30 in Killifish; Muir, 1984).…”

In this study, it was attempted to identify organic compounds in an industrial wastewater originating from processing of oil/water mixtures and spent oils. For this purpose, samples of oil reclaiming wastewater were extracted with dichloromethane. By gas chromatography/mass spectrometry (GC/MS), organic wastewater constituents had been detected and tentatively identified or at least characterized which belonged to the following groups: hydrocarbons, alcohols, ethers, phenols, ketones, carboxylic acids, esters, nitrogen-containing heterocycles, and a few others. But the detected organics represented only about 2 % of TOC, which was about 5000 mg/1. Alcohols/ethers (mainly surfactants containing several ethoxy groups) were predominant among the gas chromatographically detectable substances. In all investigated samples l-(2-butoxyethoxy)-ethanol, 2-[2-(2436 GULYAS AND REICH butoxyethoxy) -ethoxy] -ethanol, pentaoxanonadecanol ( or a homologue ) and 2-phenoxyethanol were the main representatives of the identified organics. Alkanes were very low in samples treated by precipitation and could also be removed by short time contact with activated sludge Other groups of organics (except alcohols/ethers and N-heterocycles) were reduced by biosorption too. In terms of TOC about 6 % of the organics were removed by biosorption.

“…The chloroalkylphosphates have been detected in some aquatic environments by using gas chromatography (GC) and selective NPD detector (Ishikawa et al, 1985 ;Galassi & Guzzella, 1988) . These compounds are used as flame retardants in the plastic industry and are expected to be widespread in the environment (Muir, 1984) . Tris-(monochloroisopropyl)-phosphate (TCIPP) was found at surprisingly high levels in surface sediments from Lake Comabbio and Lake Varese .…”

Sediment analysis for the assessment of risk from organic pollutants in lakes

Sediment analysis in three Italian subalpine lakes, very close to each other and exposed to different anthropogenic pressure, was used to assess the risk from organic pollutants, including some very persistent and widespread micropollutants (PCB, DDT, PAH) as well as known local pollutants . Additionally, a wide-spectrum characterization of organic compounds by GLC-MS analysis allowed the detection of other classes of chemicals . The contamination levels were related to long distance transport and to local sources of pollution in the watershed . PAH, PCB and organochlorine pesticide levels agree with the load calculated from atmospheric depositions . Local sources of pollution are responsible for the contamination by aliphatic hydrocarbons and tris(monochloroisopropyl)-phosphate (TCIPP) ; these compounds were found only in the two most urbanized basins . Heavy contamination by TCIPP was found in both water and sediments ; water concentrations are considered hazardous for drinking purposes . This study shows that local contaminants, not yet included in any priority list, may single out as a major environmental concern .

One of the principal classes of flame retardants for plastics and textiles is that of phosphorus, phosphorus‐nitrogen, and phosphorus‐halogen compounds. These flame retardants are also used for wood and paper. The mechanisms of action, which may be in the condensed or vapor phase or in both, are presented. The interactions with other flame retardants are discussed. Commercial phosphorus‐based flame retardants include some inorganic compounds as well as both additive and reactive organic phosphorus systems. These materials range from simple salts to oligomeric compounds and encompass both liquids and solids. Some commercial products are pure compounds. Others are mixtures. The various compounds, corresponding structures, and specific uses are given. The toxicity of these products is discussed.
