| bioaccumulation of polybrominated diphenyl ethers by the freshwater benthic amphipod gammarus pulex. | this study reports on the relationship between polybrominated diphenyl ether (pbde) levels in water, sediment, and the benthic macroinvertebrate gammarus pulex, which plays a major ecological role in freshwater ecosystems. samples were taken in a periurban watershed (near paris, france), and pbdes were systematically detected in sediment (≤727 ng g(-1) oc) and g. pulex (≤264 ng g(-1) lipids). pbdes were also occasionally detected in the water column at low levels (∑ pbdes < 1.5 ng l(-1)). the lo ... | 2012 | 22367498 |
| seasonal variability and inter-species comparison of metal bioaccumulation in caged gammarids under urban diffuse contamination gradient: implications for biomonitoring investigations. | although caging of gammarus species offers promising lines of inquiry to monitor metal bioavailability in freshwaters, the interspecies responsiveness to metal exposures is still unclear. in addition, abiotic factors inherent to transplantation can hamper the interpretation of field bioaccumulation data. to assess the relevance of using gammarids as biomonitors, we investigated the seasonal influence on metal bioaccumulation in two common species, gammarus pulex and gammarus fossarum. during fou ... | 2015 | 25577736 |
