Heavy Metals Contamination Mercury (Hg) and Lead (Pb) in Water, Sediment and Torpedo Scad Fish (Megalaspis cordyla L) in Palu Bay, Sentral Sulawesi)

Abstract

Palu bay waters is susceptible to heavy metal pollution due to the inclusion of the waste product of Palu city, and such as agriculture, and traditional mining. The objective of this research was to determine the contamination of heavy metals mercury (Hg) and lead (Pb) in water, sediment, and torpedo scad fish (Megalaspis cordyla) Sampling was done purposively at 10 sampling points. Parameters of water quality measurements were done in the field for temperature, pH, brightness, turbidity, and dissolved oxygen (DO), and at laboratory analysis for salinity, chemical oxygen demand (COD), ammonia, and nitrates. Heavy metals were analized by following APHA, and Indonesian National Standard (SNI) methods. The results showed that Hg consentrations in water, sediment, gill, meat, liver, and spleen were 0.0008-0.0042 mg/l, 0.017-0.287 mg/kg, 0. respectively. Pb concentrations in water, sediments, gill, meat, liver, respectively. The average of Hg and Pb concentrations in the water had exceeded the specified quality standards, while in the sediment were still below the quality standards. The average of Hg and Pb concentrations in all observed fish organs were below the quality standards, except for Pb concentrations in gill, liver, and spleen.

Potential Use of Alkaline-Activated Indonesian Pumice Powder as Lead Adsorbent in Solution System

“…According to the DALY's ranking for the worst polluting industries, based on contribution to the global burden disease, ULAB (used lead-acid battery) and lead smelting were positioned respectively as the first and third of the list (Mills-knapp et al, 2012;Pure Earth & Green Cross Switzerland, 2016). Environmental contaminations of Pb in Indonesia, among others, were reported by Paundanan, Riani, & Anwar (2015); Riza, Bambang, & Kismartini (2016); and Tjahjono & Suwarno (2018). Waters of Kartini Beach, Central Java contained Pb of 0.009 mg.L -1 (Riza et al, 2016), while that of Palu Bay, Central Sulawesi was of 0.013-0.0392 mg.L -1 (Paundanan et al, 2015), and that of the river of Demak Estuary, Central Java ranged from 0.6037 to 0.6647 mg.L -1 (Tjahjono & Suwarno, 2018), all were surpassing the water quality standard set in the Environment Minister Decree, Government of Indonesia No 51 year 2004 (i.e.…”

Impact of Coastal Reclamation on Seagrass Habitat in Palu Bay, Central Sulawesi, Indonesia

“…High water turbidity will reduce the penetration of light needed by seagrasses to photosynthesize, and can therefore reduce the productivity of seagrass beds [20]. While in Palu Bay, the average turbidity values greater than 5 NTU [15,21], meaning that turbidity has exceeded the national seawater quality standard. According to [3], high turbidity will be followed by the sedimentation process, while seagrasses include are sensitive to sedimentation and lack of light availability.…”

Assessment of heavy metals pollution in sediment of Citarum River, Indonesia

“…Sediment is crucial components of the water environment which acts as pollutant sinks, therefore investigating contamination in sediment is very important. There have been many studies about heavy metals in sediment (Paundanan et al, 2015;Syahminan et al, 2015). In sediment, heavy metals can be present in various chemical forms.…”
