Concentration analysis in vegetables ofQinhuangdao City and their health-threateninghazards assessment of heavy metals

REN Yan-jun,MA Jian-jun(Center of Analysis and Test,Hebei Normal University of Science & Technology,Qinhuangdao 066004,Hebei,China)  
The present paper is to introduce our heavy metal content analysis in the vegetables of Qinhuangdao City and the investigation findings of the health hazards to be brought about by such pollutants.In order to investigate the heavy metal pollution in the vegetables and provide a scientific implication for the food safety and environmental quality control,we have collected 5 categories of vegetable species including 37 kinds of 518 samples from Qinhuangdao greens markets.As a result,we have discovered the heavy metal contents like As,Cd,Cr,Cu,Ni,Pb and Zn in them.When comparing the actual contents of the heavy metal quotients in the samples to the standards of the national FAO/WHO vegetable health-protection indexes and the target hazard quotients(THQ),we have made systematic analysis of the pollution situations and the likely health hazards to be brought about to the local residents.The results of our analysis can be shown as follows: The average content of As,Cd,Cr,Cu,Ni,Pb and Zn can be illustrated as 0.036 mg/kg,0.019 mg/kg,0.079 mg/kg,0.491 mg/kg,0.104 mg/kg,0.035 mg/kg and 2.632 mg/kg respectively,of which about 12.17% of the samples were found exceeding the state-stipulating heavy-metal content limit,with Cd and Cr being the main contaminants.The heavy metal component pollution indexes account for 0.828±0.854,about 23.75% of the samples under discussion were subjected to different degrees of pollution,the mild pollution of which accounts for 17.18%,whereas the moderate one of which accounts for 3.47% and severe case accounts for 3.09%,with the 16.22% of the samples categorized into the warning category.If the pollution parts of the suffered vegetables are considered,the stems of the greens were polluted most heavily(56.76%),followed by the leaves(36.01%).If the health hazard degrees to be accounted for,3 kinds of them for adult consumers and children consumers can be classified as: the first kind is estimated to bring about 29.37% of health hazards to adults and 37.84% of hazards to the children.And,for the second kind,it is likely to cause harm to the health of adults with a rate of 0-9.95%,while to the health of children with a risk hazard rate of 6.67%-18.96%.As to the third kind of vegetables,the health hazard rate both to adults and to children is estimated to be zero.And,finally,it has to be pointed out that the combined health hazard factors are mainly caused by the pollution of Cd and Cr,and greater health hazards to hit children tend to be more serious than to adults.
