| 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 |
| 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 |
| the effects of mariculture on heavy metal distribution in sediments and cultured fish around the pearl river delta region, south china. | thirty-six sediment samples were collected from six mariculture sites and corresponding reference sites (approximately 200-300 m away from each mariculture site) to study the effects of mariculture on heavy metal: copper (cu), zinc (zn), chromium (cr) and lead (pb) distribution in sediments and cultured fish around the pearl river delta region, south china. the mean concentrations of cu, zn, cr and pb in all mariculture sediment samples were 109, 273, 99 and 33 mg/kg, compared with 63, 209, 56 a ... | 2016 | 26807936 |
| the measurement of bisphenol a and its analogues, perfluorinated compounds in twenty species of freshwater and marine fishes, a time-trend comparison and human health based assessment. | our previous study in 2011 reported the detection of bpa and pfaas in 20 species of marine and freshwater fishes. with an emerging evidence to suggest the metabolic-disrupting effects of bpa/pfaas in animals, the present study was aimed to provide a time-trend analysis to determine the current concentrations of pfaas and bpa in 20 commercially available hong kong species of fishes. since the manufacture and use of bpa is being prohibited in most nations, the introduction of bpa alternatives has ... | 2017 | 28552249 |
| use of soybean meal and papain to partially replace animal protein for culturing three marine fish species: fish growth and water quality. | the main aim of this study was to investigate the feasibility of using soybean meal added with papain to replace half of the fishmeal used in the moist pellets (49% fishmeal and 45% trash fish) developed by the hong kong agriculture, fisheries and conservation department (afcd) for culturing marine fish. gold-lined seabream (rhabdosargus sarba), brown spotted grouper (epinephelus bleekeri) and pompano (trachinotus blochii) were farmed at one of the research stations (kat-o) of afcd, for a period ... | 2016 | 27498342 |
