Bioindicator organisms: heavy metal pollution evaluation in the Ionian Sea (Mediterranean Sea--Italy).
TLDR
The metal concentrations recorded at the clean stations may be considered as useful background levels to which to refer for comparison within the Mediterranean area, but on the contrary, the high levels of chromium and mercury found respectively in the areas near the Gulf of Taranto and at Capo Passero need frequent monitoring.Abstract:
Trace metal concentrations of mercury, cadmium, lead and chromium in Patella caerulea, and Mullus barbatus were investigated to provide information on pollution of Ionian Sea, since these metals have the highest toxic potential. High chromium levels (0.47–0.97 μg g−1 ww) were registered in limpet samples collected from two station near the Gulf of Taranto, while elevated concentration of mercury (0.31–1.50 μg g−1 ww) were found in mullet specimens from Sicily. The metal concentrations recorded at the clean stations may be considered as useful background levels to which to refer for comparison within the Mediterranean area. On the contrary, the high levels of chromium and mercury found respectively in the areas near the Gulf of Taranto and at Capo Passero being of concern in terms of environmental health need frequent monitoring.read more

TL;DR: Arsenic target hazard quotient (THQ) values, suggest that human should minimizing meals/week of analyzed species to avoid deleterious effect during lifetime, and with As cancer risk assessment, for most of the fish, the risk for cancer is greater than the acceptable lifetime risk of 10(-5).

TL;DR: Although some metals concentrations exceed the limits set by the European regulation, the estimated weekly intake was below the Provisional Tolerable Weekly Intake established by theEuropean Food and Safety Authority, and the Target Hazard Quotient values indicate that there is no carcinogenic risk for humans.

TL;DR: The results obtained definitively confirm the goodness of the fishery commercial resources in one of the most important seafood market of the central Mediterranean Sea and represent a positive data for the assessment of the good environmental status for descriptor 9 of the Marine Strategy Framework Directive in this area of the basin.

The use of biological indicator organisms to monitor trace metal pollution in marine and estuarine environments—a review
TL;DR: A review of the use of indicator organisms to study trace metal pollution can be found in this paper, where it is suggested that the macroalgae and bivalve molluscs are the most efficient and reliable indicators developed to the present time.

Chromium as an Essential Nutrient for Humans
TL;DR: Chromium is an essential nutrient required for sugar and fat metabolism and given to people with impaired glucose tolerance or diabetes leads to improved blood glucose, insulin, and lipid variables as well as improving lean body mass in humans and swine.

Trace element content and body size in molluscs
TL;DR: T trace element concentrations in shellfish are expressed on a weight-specific basis (as µg g−1) and highest values are often recorded in the smallest individuals, making it difficult to assess whether observed differences in element tissue concentrations between populations reflect real differences in environmental trace element constitution.
