Phthalate ester plasticizers in freshwater systems of Venda
Phthalate ester plasticizers were determined in rivers and dams of the Venda region, South Africa. Liquid-liquid extraction, column chromatographic clean-up and capillary gas chromatography were the methods used for the quantitative analyses.

Phthalate ester plasticizers in freshwater systems of Venda
Levels of phthalates in water samples from the rivers and dams ranged from 0.16 mg/ to 10.17 mg/ and varied between 0.02 mg/kg and 0.89 mg/kg in sediments. Generally, the highest concentrations...

- How are phthalate ester plasticizers determined?
- ABSTRACT Phthalate ester plasticizers were determined in rivers and dams of the Venda region, South Africa. Liquid-liquid extraction, column chromatographic clean-up and capillary gas chromatography were the methods used for the quantitative analyses.
- Are phthalate esters found in rivers in South Africa?
- They are, however, comparable to the values recorded for phthalate esters in the rivers of south-western Nigeria (Fatoki and Ogunfowokan, 1993a) but lower than the levels reported for rivers in the Eastern Cape Province of South Africa (Fatoki and Noma, 2002).

- Do phthalate esters and pharmaceuticals exist in river sediments in Taiwan?
- The aim of this study was to understand the occurrence, spatial distribution, and temporal variation of six phthalate esters and pharmaceuticals in river sediments in Taiwan. Surface sediments were sampled seven times at five bridge sites along the Dianbao River in Southern Taiwan. The sediment samples were collected using an Ekman grab sampler.
- Which phthalate ester is most prevalent in water systems?
- On the contrary, the general pattern emerging from this study was that DBP, used primarily as a plasticizer but which also has a wide variety of non-plasticizer use, such as ingredients in paints, inks, glue, nail polish, hairspray and insect repellents, was found to be the most predominant phthalate ester in the water systems.
