摘      要：In this study,a set of coupled multi-media compartments(i.e.,sediment,soil,water and vegetable)was used to assess ecological and health risks from the ingestion of 11 PTEs(Pb,Cd,Cr,As,Hg,Cu,Zn,Ni,Co,Fe,and Mn)and their transportation routes in the water-soil-plant system from the coastal Bhola Island,*** mean concentrations of Cd,Pb,and Co for soil and Cd,Co,and As for sediment were higher than their reference *** contrast,Cd,Pb,and Ni concentrations in water surpassed the acceptable limits set by national and international laws and were considered unsuitable for drinking *** demonstrated high Pb and Cd contents,demonstrating a potential food safety risk to the *** of principal component analysis(PCA)revealed that Cd,Pb,Hg,Cu,Ni and Zn sources were likely to be anthropogenic,especially agro-farming inputs,whereas the Fe,As,Cr,Mn,and Co sources were similar to natural ***,Cd,Pb and Co are the key contaminants in the study area and pose the elevated health and ecological risks in the coastal *** and Pb exhibited higher ecological risks in soils and sediments,as Pb had the highest bio-accessibility(BA;0.02±0.003)and Cd possessed a high bioaccumulation factor(BCF;0.004±0.006).The self-organizing map analysis recognized three spatial patterns which are good agreement with *** average hazard index(HI)values for soil were above the permissible level(HI1)set by the respective agency;two times higher HI values were noticed for children than adults,suggesting children are highly susceptible to health *** monitoring and source controls for Cd and Pb,along with agro-farming management practices,need to be implemented to reduce the risk of PTE contamination to the aquatic ecosystem and its inhabitants.
