Abstract：Phthalate esters(PAEs)are of widespread concern due to their high toxicity and wide distri-bution.Solid phase extraction and gas chromatography were used to analyse the levels of four common phthalate esters,DMP,DEP,DBP and DEHP,in water and organisms from Qingdao's nearshore wa-ters,and to assess the ecological risk of PAEs in water to biota such as algae,fish and crustaceans,as well as the health risk to adults and children due to the consumption of marine organisms.The results showed that the total PAEs concentrations in seawater ranged from 3.31-16.2 μg/L and the total PAEs concentrations in marine organisms ranged from 125.3-865.4 μg/kg.The ecological risk of DMP and DEP in seawater was low and largely negligible,but DBP and DEHP posed a moderate to high risk to algae,crustaceans and fish,especially DEHP for algae and crustaceans with mean risk entropy values of 29.80 and 3.55 respectively.In particular,the carcinogenic risk levels caused by the consumption of shrimp nuns and pike crabs exceeded the risk thresholds.Therefore,the ecological and health risks of PAEs in Qingdao's nearshore waters need further attention.
