Trace elements in Mediterranean seagrasses and macroalgae. A review

Giuseppe Bonanno, +1 more
- 15 Mar 2018 - 
TL;DR: The combined use of seagrasses and macroalgae as bioindicators still lacks validated protocols, whose application should be strongly encouraged to biomonitor exhaustively the presence of trace elements in the abiotic and biotic components of coastal ecosystems.

Trace elements in Mediterranean seagrasses: Accumulation, tolerance and biomonitoring. A review.

Giuseppe Bonanno, +1 more
- 15 Dec 2017 - 
TL;DR: Seagrasses showed similar patterns of accumulation: the highest concentrations of As, Hg and Pb were found in the roots, whereas those of Cd, Cr, Cu, Mn, Ni and Zn were finding in the leaves.

- 01 Apr 2019 - 
TL;DR: It is suggested that exposure to the analysed metals (Cd, Pb, Cu and Zn) through seaweeds consumption does not raise serious health effects to consumers and it is safe for human consumption.

Arsenic toxicity: The effects on plant metabolism

Patrick M. Finnegan, +1 more
- 06 Jun 2012 - 
TL;DR: The two forms of inorganic arsenic, arsenate (AsV) and arsenite (AsIII), are easily taken up by the cells of the plant root Once in the cell, AsV can be readily converted to AsIII, the more toxic of the two forms AsV and AsIII both disrupt plant metabolism, but through distinct mechanisms as mentioned in this paper.

Q1. What are the contributions in "Trace metal accumulation in marine macrophytes: hotspots of coastal contamination worldwide" ?

This study compiles, from 155 peer review research articles, almost 23,000 estimates of trace metals ( As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb and Zn ) contents in natural populations of marine macrophytes ( seagrasses, chlorophytae, phaeophytae and rhodophytae ) worldwide. The objective was to explore the distribution of these metals, to examine its trends of accumulation and to identify hotspots of coastal pollution. This work aims to provide a reference for futures studies. 

The extensive database of metal concentration in marine macrophytes compiled in the present work could help in future monitory programs of the coastal pollution and provide a reference for futures studies. 

In marine macrophytes Co, Cu, Fe, Mn, Ni and Zn act as micronutrients working as cofactors in several enzymes and vitamins, and in several metabolic paths [3,4]. 

Since metal accumulation in marine macrophytes depends strongly on the specie, location, and season [8], a global overview of metal composition might help to better understanding of biological requirements and tolerance under different environments conditions. 

The Bay of Bengal, in the Indian Sea, is another hotspot of trace metal contamination due to the elevated concentration of metals found in marine macrophytes. 

The authors have found that 1) phaeophytae present significantly higher concentrations than seagrasses, chlorophytae and rhodophytae of As, Cd, Co and Zn; 2) Chlorophytae shows the highest concentrations of Fe and Mn; 3) Seagrasses present the highest concentration of Cu and the lowest of Hg and Mn; and 4) Rhodophytae have significantly lower concentrations in 5 of the 11 trace metals studied, than the other plants: i.e. Cr, Cu, Fe, Pb and Zn. Moreover, the atomic ratio of metals concentrations in each group show similar pattern of accumulation suggesting that the ability to accumulate trace metal is equal in all macrophytes, regardless the different species and locations. 

The particular geography of Chile and the upwelling that occurs in its coast could increase the concentrations of trace metals in marine macrophytes. 

Due to marine macrophytes are good tools to control metal concentrations, the authors have identified some hotspots of trace metals in coastal areas worldwide (Fig. 1). 

The data set includes concentration of eleven trace metals (As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb and Zn) in marine macrophytes worldwide. 

The extensive database of metal concentration in marine macrophytes compiled in the present work could help in future monitory programs of the coastal pollution and provide a reference for futures studies.
