A biomonitoring study: trace metals in algae and molluscs from Tyrrhenian coastal areas.

TL;DR: In nine mollusks' tissues, there are significant correlations between these elements in adjacent main group or subgroup in periodic table of elements, and principal component analysis (PCA) and correlation analysis were used to study the relationships between these heavy metals.

TL;DR: The findings suggest heavy metal contamination of river water and sediments have reached alarming levels, which is well corroborated by elevated level of metal accumulation in V. bengalensis.

TL;DR: This study shows that animal excrement can be used as bioindicators for the level of metal contamination in the marine environment, with the advantages of easy sampling, accurate detection, and reconstructing historical metal contamination trends by long-term monitoring of sedimentary excrements.

TL;DR: Evaluation of the risk associated to molluscs consumption for human health suggested that there is no evident risk for a moderate Mytilus g.w. consumer, however heavy metals concentrations must be monitored periodically and carefully with respect to the consumers health.

TL;DR: The object of this paper is that of pointing out the most important lines in the current state of knowledge in this field, evaluating the methodological applications and their advantages/disadvantages with respect to traditional surveying methods.

TL;DR: It is not valid to compare absolute accumulated metal concentrations in biomonitors interspecifically, although interspecific comparisions of rank orders do allow cross correlations of relative bioavailabilities of heavy metals to different biomonitor at the same sites.

TL;DR: All heavy metals, including those that are essential micronutrients (e.g. copper, zinc, etc.), are toxic to algae at high concentrations.

TL;DR: The background metal concentrations in Fucus algae are specific to a sea region; their variations are connected not only with the trace element contents in abiotic components of the environment, but also with the functioning of coastal ecosystems.
