Rhizophora stylosa as a protector against overwhelming copper (Cu) and lead (Pb) metal substances and how they affect on Belawan’s water quality

Rhizopohora stylosa, Rhizopohora mucronata, Rhizopohora apiculata, and Bruguiera gymnorhyza are among the rare types of mangrove found in coastal areas. The presence of these mangrove species in the coastal environment could be a boon to the environment. R. stylosa is one of the many species, and it can be used as a plant that collects heavy metals present in coastal areas. As a result of out-of-collection metals from various mechanical exercises that exist surrounding waterways and estuaries. From May to August 2021, researchers studied the capacity of R. stylosa to withstand the heavy metals copper (Cu) and lead (Pb) and their impact on water quality. This investigation took place at the Belawan Stream Estuary in Baristan Medan, as well as the Office of Timberland Development’s research center at the College of North Sumatra. Different types of mengrove plants found in coastal areas have unique strategies for dealing with contaminaton caused by heavy metals. Constructing various types of overpowering netal at various portions of the tree is one of the few methodologies used by mangroves. R. stylosa is a type of mangrove that may collect a lot of metal in its roots and stem before clearing it out. Overwhelming metals will degrade water quality, which will, in turn, degrade the condition of the biological system as a whole. The overpowering metal substance of Cu and Pb in the R. stylosa mangrove was found to be higher than that of Pb. The Cu component was found to be more notable than Pb in the water contained within the developing put of R. stylosa. Meanwhile, the mud material in which the R. stylosa mangrove grows creates an abundance of metal substance that is less than that of Pb.
