| influence of biological and ecological factors on the bioaccumulation of polybrominated diphenyl ethers in aquatic food webs from french estuaries. | previous studies have shown the worldwide presence of six congeners of polybrominated diphenyl ethers (pbdes) in marine biota (bde-28, -47, -99, -100, -153 and -154). the objective of the present study was to document their presence, their level and their transfer in the food web of two major estuaries in france, the loire and the seine. pbdes were quantified in eight principal species from the loire, representing primary consumers (the bivalve scrobicularia plana), omnivores (the worm nereis di ... | 2006 | 16764911 |
| biological indices, energy reserves, steroid hormones and sexual maturity in the infaunal bivalve scrobicularia plana from three sites differing by their level of contamination. | the aim of this work was to investigate in situ biometric (condition index, hepato-somatic index, gonado-somatic index), biochemical (glycogen, lipids, sexual steroids) and histological (sex, sexual maturation stage) variables in the infaunal bivalve scrobicularia plana. first, the reproductive cycle of s. plana was assessed by collecting bivalves from a reference site (the bay of bourgneuf, fr) in april, may, july, september and november 2005 and in january and march 2006. then, s. plana were c ... | 2008 | 18511050 |
