| risk assessment of pcdd/fs levels in human tissues related to major food items based on chemical analyses and micro-erod assay. | nine groups of food items (freshwater fish, marine fish, pork, chicken, chicken eggs, leafy, non-leafy vegetables, rice and flour) and three types of human samples (human milk, maternal serum and cord serum) were collected for the analysis of pcdd/fs. results of chemical analysis revealed pcdd/fs concentrations (pg g(-1) fat) in the following ascending order: pork (0.289 pg g(-1) fat), grass carp (ctenopharyngodon idellus) (freshwater fish) (0.407), golden thread (nemipterus virgatus) (marine fi ... | 2009 | 19535140 |
| residual levels of ddts and pahs in freshwater and marine fish from hong kong markets and their health risk assessment. | axial and ventral muscle from 10 each species of freshwater and marine fish purchased from markets in hong kong were analyzed for dichlorodiphenyltrichloroethane (total ddts including dde, ddd and ddt) and polycyclic aromatic hydrocarbons (pahs). among the 10 freshwater fish species, rice field eel (monopterus albus) showed significantly higher levels of ddts in both ventral (125 ng/g wet wt) and axial muscle (127 ng/g wet wt) than the other species. the highest concentration of pahs was detecte ... | 2007 | 16870232 |
