The characters and health risk assessment of vegetable Pb in Jilin Suburb
108 vegetable samples were collected from Jilin suburb vegetable production base,and Pb of samples was measured using graphite furnace atomic absorption spectrophotometer (GF-AAS).Results showed that the average Pb of vegetable was 0.06 mg·kg-1 fresh weight,with only 1.5% above the Safety Requirements.Single-factor contaminant index was utilized for assessment.It was found that vegetable Pb order as following:leaf vegetables>fruit vegetables,dark vegetables>light vegetables.The average daily intake (DI)Pb of per standard person was urban 21.6μg ·d-1 and rural 18.7μg ·d-1,as well as economical family 22.1μg ·d-1and poor 18.3μg ·d-1,indicating that vegetable Pb in Jilin suburbs were safety.The Pb health risk was assessed based on the target hazard quotients (THQ).The study showed that THQurban =THQhigh >THQmedium >THQlow =THQrural,indicating the health risk via vegetable consumption in rural was relative lower than that in urban area.Assessment results proved that the vegetables Pb in this area is no health risk to persons.
