SEA HOLY (Acanthus
ilicifolius) VIABILITY TEST ON HEAVY METAL: LEAD (Pb) and CADMIUM (Cd)
Abstract
- The development become in increased human activity in various sectors, such
as: industrial, residential, agricultural, and other sectors. Human activity in
the development that not consider the environmental aspects, impact on
improving the quality and quantity of waste that will contaminate various
environmental parts. Heavy metal pollution is a serious attention, if absorbed
and accumulate in the human body can be disorder to health and cause death.
Heavy metals are toxic pollutants in all environmental parts, such as Pb (lead)
and Cd (cadmium). Plant species of Acanthus ilicifolius an annual shrub, woody, single leafy, spiny,
flowering compound, fruit ovoid, contain four seed each fruit. Distribution in
the tropics, especially Indonesia, often found along the edge of the river with
the sea, and in the mangroves near the coast. Can grow to 500 m above sea
level. The study aims to determine the viaability of Acanthus ilicifolius on heavy metals (Pb and Cd). Research conducted at
the laboratory scale in greenhouse of Environmental Engineering - ITS. Methods
with range finding test use three replications, observation gradually over two
weeks to determine the letal concentrations of heavy metal. Result showed that Acanthus ilicifolius can’t
live in concentration for lead ( Pb ) and cadmium ( Cd ) is 8000 mg/L and 300
mg/L.
