Akumulasi logam berat (Pb dan Cu) pada Akar dan daun mangrove Avicennia marina di Sungai Lamong, Jawa Timur

Abstract

Mangrove ecosystem of Lamong River is located in an area with dense human activities such as industrial, heavy traffic, settlements and harbour activities. These activities could triggered the input of heavy metals, especially Pb and Cu. Mangrove ecosystem can be developed as a control of heavy metal pollution and also as a pollutant trap. In this study, the analysis of heavy metals (Pb and Cu) in water, sediment and mangorve's roots and leaves were measured. The aim of this study was to determine the ability of Avicennia marina's roots and leaves in absorbing heavy metals (Pb and Cu). Samples were obtained and then analysed by AAS (Atomic Absorbsion Spectrofotometer). The result showed that heavy metal concentrations of Pb were in the range of 0.11 mg/L-16.87 mg/L and Cu in the range of 0.001 mg/L-34.84 mg/L. Avicennia marina in the study site was categorized as excluder based on BCF<1 and phytoextraction due to TF>1. The results of this study indicate that Avicennia marina can be developed into phytoremidiation agents because they was able to absorb and transfer heavy metals from the environment to their plant tissues.

The Effects of Calcium Supplementation on Blood Lead Levels and Short-term Memory of Chronically Exposed Children: A Clinical Trial Study

“…Our data indicate that Indonesian children living in an urban area are at increased risk for BLLs above the actual acceptable limit [20]. The increasing number of industries in Indonesia has been associated with rising heavy metal pollution in several areas such as in Jakarta and Medan [21], [22], [23], [24]. Research conducted in the city of Medan and Yogyakarta found that there is an apparent link between the increases of the intensity of a motor vehicle with the air lead levels in these two cities [25].…”

Ecological risks assessment of fishery commodities from heavy metal in The East Java Province, Indonesia

“…Many studies have highlighted that an increase in pollution from heavy metals in water bodies that serve as the primary water sources for various fishery activities. Several areas in East Java have been the focus of research on water pollution, including; Lamongan (Sugiyanto, Yona and Kasitowati, 2016;Awaliyah, Yona and Pratiwi, 2018), Pasuruan (Salsabila, 2021;Purnomo, 2022), and Banyuwangi (Setyaningrum et al, 2018;Yona et al, 2018). The findings from these studies reveal the presence of various heavy metals in almost all coastal areas of East Java.…”

Analisis Kualitas Perairan Berdasarkan Konsentrasi Logam Berat Dan Indeks Pencemaran Di Sungai Banjir Kanal Timur Semarang

“…Dilihat dari letak geografis Sungai Banjir Kanal Timur yang ditetapkan sebagai lokasi penelitian merupakan bagian hilir, sehingga memungkinkan terjadinya akumulasi logam berat yang terbawa oleh arus sungai dari hulu. Menurut Awaliyah et al, (2018), konsentrasi logam berat Cu dan Pb pada air mengalami peningkatan konsentrasi seiring dengan semakin dekatnya dengan muara sungai. Logam berat yang larut dalam air akan terbawa sampai ke muara dan terakumulasi sehingga konsentrasinya relatif besar karena mudah terdistribusi.…”
