Heavy metal contamination ststus in the soil-water-rice system near coal-fired power plants in Cilacap, Indonesia
Indonesia is intensively developing plenty of coal-fired power plants to support
electricity demand growth. Some research showed the utilization of coal as an
electrical energy source may produce anthropogenic contaminants (ACs) that
can accumulate in plants and environmental compartments, such as water,
soil, and air. This research was carried out to investigate the severity of the
heavy metals contamination problem, for instance, arsenic (As), cadmium
(Cd), mercury (Hg), and lead (Pb) in soil, water, rice, and rice bran using ICPMS and ICP-OES. This research demonstrated the metal contamination levels
of arsenic, cadmium, mercury, and lead in the soil, water, rice, and rice bran
were below the maximum limit, according to SNI, Codex, and FAO/WHO.
However, only a rice sample showed the lead (Pb) level above the safe limit.
Coal-fired power plant activities in Cilacap did not indicate clear evidence of
soil, water, rice, and bran heavy metal contamination. Therefore,
transformation to green energy (e.g., solar and geothermal) is highly
recommended to minimize the potential health risks of environmental pollution
due to the coal-fired power plant's by-product activities.
