Salt marsh halophyte services to metal-metalloid remediation: assessment of the processes and underlying mechanisms
Salt marshes are widely distributed and most productive ecosystems
in the temperate zones on the globe. These areas perform vital ecological
functions and are populated mainly by halophytes鈥攑lants
that are able to survive and reproduce in environments with exceptionally
high salt concentrations. In salt marshes, in addition
to tolerating high salt concentrations, salt marsh halophytes
have to cope with damages caused by multiple anthropgenic pressures
including metal and metalloid pollution. Extensive studies
have been performed aiming at exploring naturally occurring
endemic salt marsh halophytes with extraordinary potential
for metals and metalloids remediation. However, a knowledge
gap is perceptible on the basics of salt marsh halophyte adaptation/
tolerance to the joint action of damaging factors such as
high concentration of salt and presence of metals鈥搈etalloids. In
light of available literature, the current paper is critical in: (i)
highlighting ecological significance of salt marsh halophytes and their use as bioindicators or biomonitors of metal鈥搈etalloid pollution;
(ii) analyzing salt marsh halophyte significant contributions
for metal- and metalloid-remediation processes; (iii) overviewing
salt marsh halophytes鈥搈icrobes interaction influence on metalphytoremediation
processes; and (iv) cross-talking important physiological/
biochemical strategies adopted by salt marsh halophytes
for salinity-, metal-, and metalloid-tolerance. Conclusively, the paper
highlights important aspects so far less explored in the context of
salt marsh halophyte services to metal鈥搈etalloid remediation and
underlying mechanisms. The discussion will enable researchers
and environmentalists to set further exhaustive studies aiming at
efficient and sustainable management of rapidly mounting salt
