Abstract:
The active synthetic constituent of oral contraceptives 17α- ethinylestradiol (EE2) and its natural steroidal estrogen analogues are being released into the aquatic environment mainly via wastewater treatment plants (WWTPs). Although steroidal estrogens have been frequently reported in very low concentrations in the environment, they have been placed at the top of the list of endocrine disrupting chemicals (EDCs) for their high estrogenic activity in non-target aquatic species like fish and frogs. Almost 30 years worth of intensive research has moved the problem of endocrine disruption in the

Traditional assessments of contaminated sites require the collection and analysis of field media. Specifically, sediment analysis is used to determine type of contaminant as well as total contaminant concentrations (TCC). Although TCC can be used to determine if a site is contaminated, it is unable to adequately predict exposure and bioaccumulation in organisms. Biota-sediment accumulation factors were originally introduced to calculate and predict expected exposure to organisms based on sediment TCC. As they have been shown to be unreliable with field sediments, their use is limited. Alterna

Abstract:
The production of engineered nanomaterials is an emerging and rapidly expanding industry. It exploits the capacity for materials to be manufactured to present particular properties distinct from the bulk material, through tailoring of the particle size and surface functionality. This ability to fine tune particle properties at the nanoscale is responsible for the explosion in uses of engineered nanomaterials in industries as diverse as cosmetics and medicine, to “green” technologies and manufacturing. However, this increased reactivity at the nanoscale, defined as having at least one dimension

Abstract:
Des cultures de Chlorella vulgaris ont été réalisées en triplicata sur de longues périodes (15-30 jours) en autotrophie et en mixotrophie afin d’étudier l’effet de Mg2+ sur les microalgues et déterminer sa concentration dans la biomasse au cours de la croissance. Différentes concentrations ont été testées (de 8.9 à 465 mg L-1). Ceci a montré que le Mg2+ n’est pas toxique pour les algues à des concentrations élevées provoquant habituellement l’inhibition de la croissance dans le cas d’autres ions divalents (métaux lourds). Des bilans matière ont été établis et vérifiés avec une précision satisf
