DEHP, bis-(2-ethylhexyl)phthalate, is one of the most prominent phthalate contaminants in drinking water. DEHP is also used as a plasticiser during plastic manufacturing. When ingested, it is a cancer-causing hazard and presents a high risk of liver function disorders. For this reason DEHP is a banned substance during food production, under the Restriction of Hazardous Substances (RoHS) Directive by the EU, and levels must be monitored. Although a banned substance, commercial sport drink manufactures have been known to substitute palm oil, a common emulsifier, for the more cost effective DEHP.
SCION Instruments developed a method for the identification of DEHP using HPLC and a Diode Array Detector (DAD)
