This study was to investigate survival, growth and accumulation potential of Acalypha wilkesiana in phytoextraction of heavy metals contaminated soil. Acalypha wilkesiana was tested to evaluate its tolerance and phytoextraction capacity in soils contaminated with metals. It was tested under 10 mL of 100 mg/kg of As, Cr, Cd, Co, Cu, Fe, Mn, Ni, Pb, and Zn solution, along 240 days in greenhouse experiment with harvesting period of 60 days interval. Twenty four cuttings from Acalypha wilkesiana were subjected to the same treatment. Plants roots stem and leaves were dry-digested and analyzed using Atomic Absorption Spectrophotometer (AAS). Results show that Fe was the most accumulated metal followed by Cu, Mn, As and Zn with 5002.4, 542.7, 492.2, 396.7 and 308.2 mg/kg, respectively. The concentration of Cr, Ni, and Co was 101.2, 99.09, and 89.63mg/kg respectively. The highest concentration of Pb was 46.44 mg/kg, Cd was not detected by the plant. Bioconcentration Factor (BCF) of metals were above unity in root, stem, and leaf except for Fe which showed a value below the unity, and Pb shows highest BF value of 7.79. The Translocation Factor (TF) of Cr, Co, Fe, Ni, and Pb were higher, while that of As, Cu, Mn, and Zn were below the unity, Co showed the highest value of 15.93. Furthermore, Extraction Coefficient (EC) of Cr, Co, Ni, and Pb were greater than 1, while for remaining metals were lower than unity, the highest EC was observed from Pb with a value 17.21.

Sanur Beach is one of the tourist destinations that is often visited by national or international tourists. The number of tourism activities can increase pollutants entering the waters, one of which is heavy metals. Heavy metal content in waters can come from various sources of activity, one of which is lead (Pb) and cadmium (Cd). Seagrass E. acoroides are found in the waters of Sanur Beach. Seagrass can absorb heavy metals because it interacts directly with the column to absorb metal ions in the water. The purpose of this study was to determine the value of bioconcentration and translocation factors for the heavy metal content of cadmium (Cd) and lead (Pb) in E. acoroides seagrass in the waters of Segara Ayu Beach, Semawang Beach, and Mertasari Beach and to determine their suitability with the quality standards of the Bali Governor Regulation.

STUDI PENURUNAN KADAR LOGAM BESI (Fe) DAN LOGAM TEMBAGA (Cu) PADA AIR EMBUNG MENGGUNAKAN ADSORBEN NANOSILIKAABSTRAKPolusi limbah logam berat dalam air merupakan satu permasalahan lingkungan yang penting. Dalam mengatasi permasalahan tersebut dapat dilakukan purifikasi terhadap air tersebut. Metode yang dapat digunakan untuk purifikasi limbah sangat beragam salah satunya adalah absorpsi. Secara umum metode absorpsi telah banyak digunakan dalam purifikasi air limbah. Metode absorpsi dapat menurunkan kadar logam yang terlarut pada limbah. cair dengan cara menyerap logam-logam tersebut ke dalam permukaan absorbennya. Tujuan dilakukan penelitian ini adalah  untuk menurunkan konsentrasi logam besi (Fe) dan tembaga (Cu) menggunakan adsorben nanosilika. Penelitian ini menggunakan variabel bebas yaitu waktu pengadukan (20 menit, 40 menit, dan 60 menit). Hasil akhir filtrat air embung kemudian diukur absorbansinya menggunakan Spektrofotometer Serapan Atom. Berdasarkan hasil analisa menggunakan instrumen SSA diperoleh hasil bahwa tidak terjadi penurunan logam Fe maupun Cu. Dalam hal ini terjadi peningkatan konsentrasi dalam logam Fe maupun Cu, hal ini dikarenakan kurangnya waktu pengadukan dan pengaruh dari adsorben nanosilika.Kata Kunci: limbah, logam berat, nanosilika STUDY OF DECREASING METALS IRON (Fe) AND COPPER (Cu) ON EMBUNG WATER USE OF NANOSILICA ADSORBEN ABSTRACTHeavy waste pollution of heavy metals in the water is an important environment issue. To solve the problem, its can be purified the water. The methods that can be used for waste purification are very diverse, one of which is absorption. In general, the method of absorption has been widely used in wastewater purification. The absorption method can decrease dissolved metal content in the waste. liquid by absorbing the metals into the absorbent surface. Research has been conducted to reduce the concentration of iron (Fe) and copper (Cu) by using nanosilica adsorbent. This research used to independent variable that is stirring time (20 minutes, 40 minutes, and 60 minutes). The final result of filtrate embung water then measured its absorbance using Atomic Absorption Spectrophotometer (AAS). Based on the result of the analysis using SSA instrument, it is found that there is no decrease of Fe and Cu metals. There are several reasons for those problem such as due to lack of stirring time and the influence of nanosilica adsorbent.Keywords: Waste pollution, heavy metal, nanosilica

The study was conducted on heavy metals contents of water, fish tissues and sediment from Lagos lagoon complex, Nigeria. The aim was to assess the current environmental health/pollution status of the lagoon from three sample stations: Ologe lagoon [1], Badagry creek [2] and Lagos island [3]; each having three (3) hotspots. In all, twelve (11) heavy metals were determined between June and November, 2018. Heavy metals: Zn, Fe, Pb, Cu, Na, Potassium, Ca, Mn, Cd, Hg and Nickel were determined using Atomic absorption spectrophotometer (AAS). Results of mean Heavy metals in fish tissues were: Zn (0.741±0.38), Fe (5.59±8.32), Pb (0.12±0.17mg/l), Cu (0.16±0.25), Na (9.38±0.25), Ca (116.68±41.53), Mn (0.76±0.96), Pb (0.01±0.0), Cd (0.02±0.0), Potassium (12.09±2.34), Ni (0.02±0.02) and Hg (0.01±0.0). Statistical analysis showed variations in the distribution of Heavy metals which are mostly within recommended limits of WHO, FME, & LASEPA. Except for iron (Fe), which was found in excess in fish tissues, and other metals (lead), found in higher conc. in sediments than in water and fish tissues combined. This is indicative of heavy metals bio-accumulation in the study area.

Lead (Pb) has become one of the most common heavy metal contaminants, demanding research on economical remediation approaches with minimal ecological impacts. Pepper elder (Peperomia pellucida) is a fast-growing plant that can be a candidate for bioaccumulation and phytoremediation. In this study, the lead bioaccumulation of P. pellucida was assessed by determining the growth response and absorptive capacity of the plant. Plants were grown in hydroponic solution spiked with 500 mg/L of Pb for 28 days. Growth response, absorptive capacity and tolerance of plants grown in contaminated nutrient solution were determined in comparison with control plants. After 28 days of exposure, lead phytotoxicity symptoms such as wilting, chlorosis and necrosis were observed on some plants. The control plants recorded 3.08 g total dry weight (DW) compared to the 1.35 g in Pb-contaminated plants. The tolerance index (TI) of P. pellucida was at 43.40%. The plants were able to absorb lead, with the concentration of lead in the roots (158.6 µg/g) being greater than the concentration of the metal in the shoots (43.2 µg/g). Meanwhile, bioconcentration factor (BCF) and translocation factor (TF) values were recorded at 0.40 and 0.27, respectively. BCF criterion indicates that the plant is not suitable for phytoextraction, but TF value shows that the plant can be a potential excluder. The findings of the study show that P. pellucida accumulated considerable amount of lead within its tissues, indicating that the plants may be further exploited for their capacity to absorb heavy metals by tweaking several factors that may affect its bioaccumulation ability.

In this study, the concentrations of three kinds of heavy metals, namely Pb, Zn, and Cu from 3 species of mangrove that grow in Muara Angke were measured and analyzed. Our result showed that substrate of mangrove ecosystem in Muara Angke was dominated by clay (30.5% - 62.4%), silt (21.7% -35.6%), and sand (2% -39.5%). The heavy metals accumulation in roots is higher than in sediment, water and leaves with concentration of Zn as the highest. Bioconcentration Factor (BCF; content ratio of heavy metal concentrations in roots or leaves and sediment) and Translocation Factor (TF; ratio of heavy metal concentrations in leaves and roots) of non-essential heavy metals (Pb) is higher in leaves than in roots, but for essential heavy metals (Zn and Cu), the BCF and TF was higher in roots than in leaves. TF values for heavy metals Pb, Cu, and Zn were 0.98-2.59, 0.17-0.51, and 0.52-0.86, respectively. The values of root BCF of those three heavy metals were 0.71-3.17, 0.27-0.74, and 0.95-1.53, while the values of leaf BCF were 1.84-3.45, 0.07-0.34, and 0.72-1.19, respectively. Furthermore, by calculating the phytoremediation (FTD), i.e. the difference between BCF and TF, it is obtained that Sonneratia caseolaris and Avicennia marina can be used in phytoremidiation, with leaves and roots FTD of 1.93 and 2.09, respectively for Sonneratia caseolaris and 1.93 and 1.98 for Avicennia marina.Keywords: heavy metals, mangroves, phytoremidiation, Muara Angke, bioconcentration factor, translocation factor
