| first determination of the levels of platinum group metals in manta birostris (manta ray) caught along the ghanaian coastline. | tissues from manta birostris caught by fishermen from dixcove in the western part of ghana were analyzed for their platinum, palladium and rhodium concentrations (pgm). the use of chondrichthyan fish has permitted the study of trace levels of platinum group metals (pgms) which have travelled very far into the sea. the analysis showed that ghana's coastline is fairly polluted with these platinum group metals (pgms). pgm concentration in manta ray recorded a range of (0.15-0.85) microg/g for pt, ( ... | 2010 | 20440471 |
