The use of solid phase extraction and capillary GLC provides the basis for selective determination of phthalate ester plasticizers in rivers and marine water samples. Of the several solvent ratios (methanol in dichloromethane) that were tried for selective elution of phthalate esters from the C18 solid phase glass catridge, the 50/50 ratio, CH<sub>3</sub>OH in CH<sub>2</sub>Cl<sub>2</sub> (v/v) gave the best result. The method was tested on river and marine water samples that receive effluent from industries that use phthalate esters. The rivers and marine water samples are grossly polluted as several phthalate esters, for example, dimethyl(DMP), diethyl(DEP), dibutyl(DBP) and diethylhexyl(DEHP) were found present at 0.03 2 306 Â± 9.4 <span lang=AF style='font-family:Symbol;mso-ascii-font-family: "Times New Roman";mso-hansi-font-family:"Times New Roman";mso-char-type:symbol; mso-symbol-font-family:Symbol'><span style='mso-char-type:symbol;mso-symbol-font -family: Symbol'>m</span></span> gl<sup>-1</sup>. A study on uncontaminated water was done to establish bank levels.
