| heavy metal concentrations in edible bivalves and gastropods available in major markets of the pearl river delta. | molluscs are able to accumulate heavy metals and impose health hazard to consumers. the main objective of the present study is to investigate the heavy metal concentrations in edible bivalves and gastropods available in major markets of the pearl river delta. fourteen species of edible molluscs were purchased from six markets in hong kong and guangdong province. the fresh of these biota were tested for their cadmium (cd), copper (cu), zinc (zn), lead (pb), nickel (ni), chromium (cr), antimony (s ... | 2001 | 11590745 |
| organochlorines in sediments and mussels collected from coastal sites along the pearl river delta, south china. | the level and pattern of residues of organochlorine pesticide and polychlorinated biphenyls(pcbs) were analyzed in sediment and mussel (perna viridis) samples from ten coastal sites along the pearl river delta, south china. the range of total hch was < 0.01 to 0.29 ng/g freeze-dried weight in sediment, and < 0.01 to 1.35 ng/g lipid weight in mussels. average total ddts concentrations ranged from < 0.01 to 1.04 ng/g in sediment, and < 0.01 to 148.5 ng/g in mussels. average total pcb concentration ... | 2004 | 15137663 |
