| comparative biomonitors of coastal trace metal contamination in tropical south america (n. brazil). | samples of 5 bivalve molluscs (crassostrea rhizophorae, mytella charruana, anomalocardia brasiliana, anadara ovalis, phacoides pectinata), 2 barnacles (fistulobalanus citerosum, balanus amphitrite) and leaves of the mangrove tree rhizophora mangle were collected from up to 11 sites in two estuaries in natal, brazil--the comparatively contaminated potengi estuary and the comparatively uncontaminated curimataú estuary. specimens were analysed for the trace metals zn, cu, cd, fe, mn and ni, and a c ... | 2006 | 16574213 |
| biomonitoring of trace metal contamination in the potengi estuary, natal (brazil), using the oyster crassostrea rhizophorae, a local food source. | the oyster crassostrea rhizophorae was collected in september 1997 from 10 stations along the potengi estuary, natal, brazil, a mangrove-lined estuary receiving anthropogenic inputs of trace metals. c. rhizophorae is a net accumulator of trace metals and can be used as a biomonitor, the accumulated soft tissue concentrations representing integrated records of bioavailable metal fractions over the life of the oyster. significant differences in oyster accumulated concentrations (and hence bioavail ... | 2001 | 11791836 |
