Detection and risk assessment of phthalic acid esters in marketed livestock and poultry meat in Qingdao

The contents of 6 kinds of phthalic acid esters (PAEs) in marketed livestock and poultry meat in Qingdao were detected with ultrasonic solvent extraction and gas chromatography. Health risk assessment for PAEs in livestock and poultry meat was made by non-chemical carcinogen health risk assessment model.Results showed that the detection rate of PAEs in livestock and poultry meat was in the range of 10%⁹0% and the ratio of the total of PAEs (∑6PAEs) contents below 2mg·kg-1was high. The average content of ∑6PAEs in raw meat and cooked meat was 1.44mg·kg-1and 3.67mg·kg-1, respectively. There was no significant difference in ∑6PAEs content between different types of raw meat, and ∑6PAEs was higher in fish and pork meat among cooked meat. The PAEs composition in types of livestock and poultry meat was different, and in general, the ratio of di (2-ethylhexyl) phthalate (DEHP) , dimethyl phthalate (DMP) and di-n-octyl phthalate (DnOP) was high. The risk value of PAEs in livestock and fish meat was higher than that in poultry meat, mainly coming from DEHP. Compared with raw meat, the risk value of PAEs in cooked meat was higher. However, the health risk assessment value of PAEs in marketed livestock and poultry meat in Qingdao was below the international recommended standards, indicating no health risk.
