Abstract. Khodijah NS, Suwignyo RA, Harun MU, Robiartini L. 2019. Phytoremediation potential of some grasses on lead heavy metal in tailing planting media of former tin mining. Biodiversitas 20: 1973-1982. Agricultural production on tin tailings land must consider the safety of products from Pb metal contaminants. The presence of Pb metal can be overcome by using plants as phytoremediation. This study aimed to obtain information on the ability of phytoremediation of Pb by various types of grass and its interaction with the types of ameliorants in tin tailings media. Three species of grass were used, namely Pennisetum purpureum, Saccharum spontaneum, and Hymenachne acutigluma, and two types of ameliorant, namely lime and compost. The study was designed using a factorial treatment design laid out in a completely randomized design with two treatment factors, namely the type of grass and the type of ameliorant. Observations were done on growth, shoot Pb content and root Pb content. The ability of phytoremediation was assessed by using the approach of Bioconcentration factor (BCF) and Translocation Factor (TF) values. The highest phytoremediation ability was found in treatment of H. acutigluma grass treated with lime ameliorant, followed by S. spontaneum treated with lime ameliorous and S. spontaneum treated with compost ameliorant. Based on BCF values, P. purpureum and H. acutigluma were categorized as accumulators, and S. spontaneum was classified as an excluder. Based on TF values, the three types of grass used were classified as phytostabilisation. The high ability of phytoremediation in H. acutigluma was caused by its high BCF values, ​​while the high ability of phytoremediation on S. spontaneum was caused by its low translocation factor value and high Pb absorption efficiency.

ABSTRACT: Phytoremediation is a useful tool to restore heavy metals contaminated soils. This study was carried out to test two castor (Ricinus communis) cultivars [Local and DS-30] for phytoextraction of heavy metals from the soil spiked by known concentrations of seven metals (Cu, Cr, Fe, Mn, Ni, Pb and Zn). A pot experiment was laid out by using a completely randomized design. Soil and plant samples were analyzed at 100 days after planting. The data on heavy metal uptake by plant tissues (roots, leaves and shoots) of the two castor cultivars suggested that a considerable amount of metals (Fe = 27.18 mg L-1; Cu = 5.06 mg L-1; Cr = 2.95 mg L-1; Mn = 0.22 mg L-1; Ni = 4.66 mg L-1; Pb = 3.33 mg L-1; Zn = 15.04 mg L-1) was accumulated in the plant biomass. The soil heavy metal content at the end of experiment significantly decreased with both cultivars, resulting in improved soil quality. Therefore, it is concluded that both castor cultivars, Local and DS-30, can be used for phytoremediation of heavy metal-contaminated sites.

SUMMARY The objective of this study was to evaluate the macronutrient accumulations in leaf, stem, and shoot of elephant grass cv. Roxo. The treatments consisted of seven growth ages (9, 18, 27, 36, 45, 54, and 63 days) and three growing seasons (rainy, transition, and dry). A completely randomized design and a split-plot time arrangement were used, where the ages were the plots and the seasons the subplots, with three replications. Interaction between the factors age and season of cultivation for the contents and the daily accumulation rates of N, P, K, Ca, Mg, and S in leaf, stem, and shoot fractions were calculated. The margins of daily accumulation of nutrients N, P, K, Mg, and S presented positive linear behavior in all seasons studied; however, with variation in the magnitude of the response between them. The daily accumulation rate of Ca in the canopy was adjusted to a linear model for the rainy and dry seasons and to a quadratic model for the transition season, reaching a maximum of 4.60 kg ha-1 at 59.76 days of growth. The accumulation of nutrients in elephant grass cv. Roxo showed the following decreasing order: K > N > P > Mg > Ca > S in the rainy and transition seasons, while in the dry season the following decreasing order was observed: K > P > N > Ca > Mg > S.

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

Phytoremediation of heavy metal rich soil has become a practical approach nowadays. Though this method is very promising, it requires long time for complete remediation of contaminated soil. Assortment of appropriate plant for specific heavy metal is very important to decontaminate soil within short period of time. The present study was conducted on Amaranthus gangeticus, to find out its potential to remove arsenic (As) from soil within short period of time. Phytoremediation trail was followed by growing plants in varying concentrations of As contaminated soil and subsequently one month of plant growing period it removed 72%-81% of the total soil As. This species accomplish maximum accumulation capacity of 17934 mg/Kgin shoots and store 72%-78% metal in aerial parts. Several parameters that have an influence on phytoremediation potential such as time, concentration, bioconcentration factor (BCF) and translocation factor (TF) were also calculated to investigate its appropriateness as effective hyperaccumulator.

Oxalate and silica are considered antinutrients. Large quantities of oxalate and silica in plants can interfere with the uptake of essential minerals in ruminants. Therefore, the aim of this study was to compare the total silica and oxalate contents of seven varieties of Napier grass to find out which is best for cultivation. Taiwan, Zanzibar, Pakchong, Purple, Kobe, Indian, and Dwarf Napier grass were grown in a completely randomized design with three replications to determine their soluble oxalate, total oxalate, and silica contents. Plants were harvested at two months of plant maturity. Whole plant of the Dwarf Napier grass contained significantly higher soluble oxalate content than tall varieties. Total oxalate content in whole plant differed significantly among varieties. Dwarf showed the highest total oxalate content (3.23% dry matter (DM)) followed by Kobe (2.61%), Zanzibar (2.60%), Purple (2.44%), Taiwan (2.43%), Indian (2.15%), and Pakchong (1.95%). Regardless of variety, leaf tissue contained significantly higher soluble oxalate and total oxalate than stem tissue. There were no differences in silica content among them. In conclusion, the tall varieties could produce lower levels of soluble oxalate than the Dwarf variety, whereas silica content might not vary among them.Keywords: botanical fractions, mineral bioavailability, ruminant
