The chlorophyte microalga Chlorella sorokiniana was tested for the bioremediation of heavy metals pollution. It was cultured with different concentrations of Cu+2+, Cd+2+, As (III) and As (V), showing a significant inhibition on its growth at concentrations of 500 µM Cu+2+, 250 µM Cd+2+, 750 µM AsO33- and 5 mM AsO43- or higher. Moreover, the...

A field-based experiment was set up to evaluate the effectiveness of a single application of marble waste sludge (MWS) on chemical immobilization of potentially hazardous trace elements (PHE) within the soil profile of a mine Technosol under natural assisted remediation for 12 years. Results showed that MWS amendment significantly reduced soil...

Coccomyxa onubensis (C. onubensis) is an acid-tolerant microalga whose ecosystem (Tinto River, Huelva, Spain) contains high amounts of different heavy metals. However, the potential of this microalga to remove these pollutants from the environment has still not been studied. Thus, this work evaluates the tolerance and physiological response of...

Coastal protection, nutrient cycling, erosion control, water purification, and carbon sequestration are ecosystem services provided by salt marshes. Additionally, salt ponds offer coastal breeding and a nursery habitat for fishes and they provide abundant invertebrates, such as amphipods, which are potentially useful as a resource in...

The objective of this study was to assess the impact of different dietary Trp concentrations on the stress and metabolism response of juvenile Senegalese soles (Solea senegalensis). Fish (38.1 ± 1.9 g) were fed different Trp-enriched feeds (0%, 1% and 2% Trp added) for two and eight days, and later exposed to air stress for three min. Samples...

The assessment of trace metal content in our fish diet is important due to the adverse effect on human health. Despite the increasing interest about the fish quality, little information is available for Southern Spain, a region characterized by high seafood intake. Nine species from the Bay of Cádiz with high commercial value were selected....
