Toluene, ethylbenzene and three xylenes are known as toxic alkylbenzenes in crude oils. The alkylbenzenes were investigated in sun-dried salts retailed in Korea. The total contents of toluene, ethylbenzene, o-xylene, m-xylene, and p-xylene were analyzed with GC-MS through the extraction with hexane. The domestically produced sun-dried salts were monitored up to 1.11 mg/kg (toluene), 3.11 mg/kg (ethylbenzene), 0.59 mg/kg (o- and m-xylenes), and no detected as p-xylene. On the other hand, the imported sun-dried salts were showed up to 0.89 mg/kg (toluene), 1.32 mg/kg (ethylbenzene), 0.50 mg/kg (o- and m-xylenes) and 0.46 (p-xylene). Furthermore, hazard quotient of targeted contaminants and hazard index were estimated to be much lower than 1.0 in risk assessment. These results suggested that the associated health risks of alkylbenzenes in sundried salts might be negligible.
