| risk assessment of trace elements in the stomach contents of indo-pacific humpback dolphins and finless porpoises in hong kong waters. | the potential health risks due to inorganic substances, mainly metals, was evaluated for the two resident marine mammals in hong kong, the indo-pacific humpback dolphin (sousa chinensis) and the finless porpoise (neophocaena phocaenoides). the stomachs from the carcasses of twelve stranded dolphins and fifteen stranded porpoises were collected and the contents examined. concentrations of thirteen trace elements (ag, as, cd, co, cr, cs, cu, hg, mn, ni, se, v and zn) were determined by inductively ... | 2007 | 16979696 |
| temporal and spatial trends of organotin contamination in the livers of finless porpoises (neophocaena phocaenoides) and their association with parasitic infection status. | organotins (ots) are globally ubiquitous contaminants. contamination of ots, particularly butyltins (bts), has been suspected to cause immunosuppressive effects leading to subsequent infectious diseases or opportunistic infection by pathogens in marine mammals. in the present study, we collected individuals from five different populations of finless porpoises (neophocaena phocaenoides) from coastal areas of japan (seto inland sea, ise bay, omura bay, and pacific coast) and hong kong, and measure ... | 2009 | 19772937 |
| temporal trends of hexabromocyclododecanes (hbcds) and polybrominated diphenyl ethers (pbdes) and detection of two novel flame retardants in marine mammals from hong kong, south china. | concentrations of hexabromocyclododecanes (hbcds), polybrominated diphenyl ethers (pbdes), and three novel flame retardants, namely2-ethylhexyl 2,3,4,5-tetrabromobenzoate (tbb), bis-(2-ethylhexyl)-tetrabromophthalate (tbph), and hexachlorocyclopentadienyldibromocyclooctane (hcdbco), were determined in blubber samples of indo-pacific humpback dolphins (sousa chinensis) and finless porpoises (neophocaena phocaenoides). the levels of hbcds and pbdes in cetacean samples ranged from 4.1 to 519 and 10 ... | 2009 | 19806725 |
| temporal trends and pattern changes of short- and medium-chain chlorinated paraffins in marine mammals from the south china sea over the past decade. | temporal trends of short- (sccps) and medium-chain chlorinated paraffins (mccps) were examined in blubber samples of 50 finless porpoises (neophocaena phocaenoides) and 25 indo-pacific humpback dolphins (sousa chinensis) collected from the south china sea between 2004 and 2014. elevated levels of sccps and mccps were detected in all blubber samples of both cetacean species. concentrations of sccps ranged from 280 to 3900 ng·g(-1) dry weight (dw) in porpoises and from 430 to 9100 ng·g(-1) dw in d ... | 2015 | 26335162 |
| underwater sounds near a fuel receiving facility in western hong kong: relevance to dolphins. | western hong kong is home to two species of marine mammals: indo-pacific humpbacked dolphins (sousa chinensis) and finless porpoises (neophocaena phocaenoides). both are threatened in many parts of their range in southeast asia [for example, international biological research institute reports 9 (1997), 41; asian marine biology 14 (1997) 111]. in 1998, when the new hong kong international airport opened in western hong kong, small tankers (about 100 m long, cargo capacity about 6300 metric tons) ... | 2002 | 12206406 |
| temporal variation and biomagnification of organohalogen compounds in finless porpoises (neophocaena phocaenoides) from the south china sea. | polybrominated diphenyl ethers (pbdes) and organochlorine compounds (ocs) were determined in the blubber of male finless porpoises (neophocaena phocaenoides) collected in 1990 and 2000/01 from the south china sea. among the organohalogen compounds analyzed, ddts and pcbs were the predominant contaminants in the porpoises, ranging from 26,000 to 260,000 and 1400 to 28,000 ng/g lipid wt., respectively. pbdes ranged from a minimum of 84 ng/g lipid wt., in 1990 to a maximum of 980 ng/g lipid wt., in ... | 2006 | 16540219 |
| post-mortem investigations on stranded dolphins and porpoises from hong kong waters. | stranded cetaceans reported from the territorial waters of hong kong during the period may 1993 to march 1998 were examined to establish factors that may have contributed to their death. during the current study, 28 indo-pacific hump-backed dolphins (sousa chinensis), 32 finless porpoises (neophocaena phocaenoides), and four bottlenose dolphins (tursiops truncatus) were necropsied. bacteria (15 species) were isolated from nine animals. of these bacteria, 47% were of possible fecal origin reflect ... | 2000 | 10813617 |

| polybrominated diphenyl ethers (pbdes) and organochlorines in small cetaceans from hong kong waters: levels, profiles and distribution. | polybrominated diphenyl ethers (pbdes) and organochlorine compounds (ocs) were determined in the blubber, liver and kidney of indo-pacific humpback dolphins (sousa chinensis) and finless porpoises (neophocaena phocaenoides) stranded in hong kong coastal waters during 1995-2001. among the organohalogen compounds analyzed, ddts were the most dominant contaminants with concentrations ranging from 9.9 to 470 microg/g lipid wt. pbdes in hong kong cetaceans, which are reported for the first time, were ... | 2005 | 16291183 |
