Bioaccumulation of Cadmium and Lead in Prickly Pen Shell in Seribu Archipelago

Abstract

AbstrakPerairan Teluk Jakarta tercemar logam berat, sehingga perairan Kepulauan Seribu juga berpotensi untuk tercemar logam berat. Penelitian ini bertujuan untuk mengetahui kondisi kualitas air di Pulau Panggang dan Pulau Karya, menganalisis kontaminasi logam berat pada air, sedimen dan kerang kapak-kapak serta menganalisis korelasi logam berat antar ketiganya. Penelitian ini meliputi pengukuran pH, suhu, oksigen terlarut/DO, BOD, salinitas, kekeruhan dan logam berat (Cd dan Pb) pada air, sedimen dan kerang kapakkapak di perairan Pulau Panggang dan Pulau Karya. Data yang diperoleh selanjutnya dibandingkan dengan baku mutu. Kualitas air di Pulau Panggang dan Pulau Karya dilihat dari pH, salinitas dan temperatur air cenderung menuju ke kurang baik. Kontaminasi Cd dan Pb pada air pada April dan Juli, berada di bawah baku mutu Kepmen LH No.51 th 2004, namun pada Oktober di kedua tempat tersebut, Cd dan Pb melebihi baku mutu yg ditetapkan. Kontaminasi Cd dan Pb pada sedimen di kedua pulau tersebut masih berada dibawah baku mutu RNO (1981), namun Cd dalam sedimen di Pulau Karya pada Juli dan Oktober berada diatas baku mutunya. Cd dan Pb pada kapak-kapak masih berada di bawah baku mutu Ditjen POM RI No. 03725 (1989). Korelasi Cd dan Pb antara air dan sedimen positif. Korelasi Cd dan Pb antara air dan kerang paling kuat dibanding korelasi logam berat pada air dan sedimen, namun keeratan hubungan kadmium lebih tinggi dibanding timbal.Kata kunci: Cd, kapak-kapak, Kepulauan Seribu, kontaminasi, korelasi, Pb Abstract Jakarta Bay waters contaminated with heavy metals, so that the waters of the Thousand Islands are also potentially contaminated with heavy metals. The purpose of this study were to determine the condition of the water quality on the Panggang Island and Karya Island, analyze contamination of heavy metals (Cadmium and Lead) in water, sediments and Prickly Pen Shell and then the correlation. Based on Ministry of Environment decree No. 51/2004, water quality in the Panggang Island and Karya Island tend toward to low category. Cadmium and lead concentration in the water on October exceed the quality standards. In the sediment on July and October at Karya Island, concentration of cadmium were exceed the quality standar by RNO. On the other hand, cadmium and lead concentration on Prickly Pen Shell still below standard quality from decree of Director General of POM RI No. 03725. We found highest positive correlation were found between cadmium and lead accumulation in the water and on the Prickly Pen Shell, then positive correlation between cadmium and lead in the water and in the sediment. For the heavy metal contamination, we found contamination of cadmium correlation were higher than lead contamination.

Heavy metal content (Pb, Hg) in threadfin bream (Nemipterus sp.) from Banten Bay, Indonesia

“…According to [20], in March-April-May at Banten Bay is transition season from rainy to headed dry. The high concentration of heavy metals in the water at dry season that because there is dilution of pollutants so in the rainy season the concentration will be low [21].…”

“…The low of ornate threadfin bream bioconcentration was comparable with the low concentration of heavy metals in the water and sediment. The Heavy metals content must still be wary of even tough in low concentration, that because of its nature which can accumulate in the water [21]. The heavy metals content (Pb and Cd) in the water lower than sediment.…”

“…Keberadaannya di dalam perairan berbahaya bagi kehidupan makhluk hidup. Logam berat apabila terakumulasi dalam tubuh dapat menyebabkan gangguan kesehatan, karena bersifat karsinogenik, dapat menyebabkan mutasi sel, dan dalam waktu lama toksisitasnya tidak berubah (Riani, E et al, 2017).…”

Determination of Water Quality Status Based on Heavy Metal Contents in the Rainy and Dry Season Using the Storet Index in Pasuruan Sea Waters, East Jav

“…The high content of heavy metals in waters can cause contamination, accumulation and even pollution to the environment such as biota, sediment, water and so on. Based on their use, heavy metals can be divided into two groups, namely: Groups that in certain concentrations function as micronutrients that are beneficial to aquatic organisms, such as Zn, Fe, Cu, Co and metals that have no known benefits for aquatic organisms, such as Hg, Cd, and Pb [7].…”
