Inventarization of potential plant for phytoremediation on degraded land and water mined
TL;DR: In this article, the authors studied the potencies of local species to accumulate heavy metals such as Pb and cyanide and found that some species accumulated heavy metals in high concentration such as Ipomoea sp. (35.70 ppm cyanida) and Mikania cordata (Burm.f.) B.L.Robinson(11.65 ppm Pb).
Abstract: One of the most important problems in degraded mined ecosystem is contamination of soil and water by toxic substances, mainly heavymetal such as Pb and others such as cyanide. Phytoremediation could be used as an alternative technique to overcome this problem.Phytoremediation is defined as clean up of pollutans primarily mediated by photosynthetic plants. These plants have several beneficialcharacteristics such as the ability to accumulate metal in their shoots and an especially high tolerance to heavy metals. This research wascarried out to study the potencies of local species to accumulate Pb and cyanide. Seventeen species were collected from mined waste area(namely tailing area) and then the cyanide and Pb accumulated in each species were analyzed. The result showed that some speciesaccumulated Pb and cyanide in high concentration such as Ipomoea sp. (35.70 ppm cyanida) and Mikania cordata (Burm.f.) B.L.Robinson(11.65 ppm Pb). A series of research is needed to prove that these species are potential as heavy metal and cyanide accumulators.© 2005 Jurusan Biologi FMIPA UNS SurakartaKeywords: phytoremediation, heavy metal, gold mined

TL;DR: In this article, a review of nanomaterials application in developing nanopesticides was reviewed, and their promising nano-formulation methods were highlighted to be considered for their sustainable innovation in the future development of effective, efficient, and safe nanopesticide formulations.
Abstract: Crop and postharvest pests and diseases have significant impact on agricultural yield loss and farmers’ incomes. Farmers mostly use synthetic pesticides to manage pests to maximize crop yields, posing potential risks for workers, consumers, and the environments. Metal- and agrochemical-based nanopesticides were potentially less toxic alternative pesticides to conventional pesticides in plant protection, while essential oils and bioactive agent-based nanopesticides and/or control released formulation have potential for use in organic food production and sustainable agriculture. Nanoparticles and/or nanoemulsions including nanomatrices of delivery agents of metals, agrochemicals, essential oils, and bioactive agents in nanopesticide formulations have been synthesized and evaluated for their effectivity against pests and disease pathogens. Some researches of nanomaterials application in developing nanopesticides were reviewed, and their promising nanoformulation methods were highlighted to be considered for their sustainable innovation in the future development of effective, efficient, and safe nanopesticides.

TL;DR: The focus of monitoring was the plant purposely cultivated because after re-vegetation, there were a very few of other plants growing naturally on reclimed coal mining area which were recorded, whereas these plants had important values.
Abstract: The focus of monitoring was the plant purposely cultivated because after re-vegetation, there were a very few of other plants growing naturally on reclimed coal mining area which were recorded, whereas these plants had important values. The research aimed to record all plants and to identify predominant plants over the reclaimed land of PT Adaro Indonesia. There were four sampling locations with 13 squares of 50 × 20 m on each location established and 2 on each square there were 5 plots of 2 × 2 m plotse made. Both plant species and its individual number of woodyplant saplings were recorded on each square, so in each plot, there were small species and its individual number of either woody-plant seedlings or non-woody plants (herbs/shrubs, grasses, ferns). The relative density and the relative frequency of woody or non-woody plants were summed to obtain the important value index (IVI) of each successional stage. There were 107 plant species consisting of 32, 43, 27, and 5 species of saplings, seedlings/herbs/shrubs, grasses, and ferns respectively. From those species, 16 species of woody plants and 2 species of herbs were planted purposely, other species grew naturally and even some of them were dominants. Either the number of plants or the dominating plant is varied according to the sampling location and the growing stage.

TL;DR: Karyati et al. as discussed by the authors analyzed the effect of mixed cropping of jabon tree (Anthocephalus cadamba) and soybean (Glycine max Merr) on growth and hydro-orological aspects on sloping lands with different steepness (a slightly steep and a steep slope gradient).
Abstract: Karyati, Sarminah S, Karmini, Simangunsong G, Tamba J. 2018. The mixed cropping of Anthocephalus cadamba and Glycine max for rehabilitating sloping lands. Biodiversitas 19: 2088-2095. Agroforestry system is one of the many alternatives to overcome problems concerning sloping lands. The objectives of this current study were to analyze the effect of agroforestry system in the form of mixed cropping of jabon tree (Anthocephalus cadamba Mig) and soybean (Glycine max Merr) on growth and hydro-orological aspects on sloping lands with different steepness (a slightly steep and a steep slope gradient). The growth parameters (survival rate, ground coverage, diameter increment, and height increment) and hydro-orological parameters (surface runoff, potential erosion, erosion hazard index, and erosion hazard level) were observed in this study. The findings showed that on the slightly steep slope (>15-25%) land, the survival rate of A. cadamba was 90%, the ground coverage of the G. max was 70-79%, the diameter and the height increments of A. cadamba trees were 1.8 cm year-1 and 13.8 cm year-1 respectively. Meanwhile, the potential erosion rate and the erosion hazard index were 32.13 ton ha-1 year-1 and 1.29, respectively. In the steeper slope (>25-45%), the survival rate of A. cadamba reached 90%, the G. max ground cover reached 60-69%, the diameter and height increments of the A. cadamba reached 1.5 cm year-1 and 12.0 cm year-1 respectively. Furthermore, in the steep slope, the potential erosion rate was 52.51 ton ha-1 year-1 and the erosion hazard index was 2.10. In addition, the potential erosion rate and the erosion hazard index in the control plot were higher than those in slightly steep slope. Therefore, it could be implied that the application of A. cadamba and G. max mixed cropping system could rehabilitate sloping lands.

TL;DR: In this paper, a low-cost phytoremediation technique using various plant families that have a high tolerance capability to accumulate heavy metals is proposed, which is supported by transcriptional and post-transcriptional gene to encoding protein transporter such as ZIP (ZRT, IRT-like protein), NRAMP (natural resistance-associated macrophage protein), and cation transporter.
Abstract: Non-essential heavy metals such as cadmium (Cd) are one of pollutants in environment which cannot be degraded naturally and induce toxicity in living things. Cadmium has already been polluted the environment which is highly dispreaded by human activities like metal coating industry. Around 13.000 tons of cadmium from human activities have already contributed to release of 30.000 tons in environment. In humans, the excess amount of cadmium can cause the potential health risk via consumption of polluted food crops and it can adversely effects the kidney and causes the bone damage. Cadmium is able to generate the damage because it has ability to mimic the properties of calcium and then inhibits the activity of a protein sensor in the organs. One of the ways to reduce cadmium levels in contaminated land area is by using bioaccumulator plants in phytoremediation technique. Phytoremediation technique offers a low-cost technique by using various plant families that have a high tolerance capability to accumulate heavy metals. This ability is supported by transcriptional and post-transcriptional gene to encoding protein transporter such, as ZIP (ZRT, IRT-like protein), NRAMP (natural resistance-associated macrophage protein), and cation transporter, which play in an important role to absorb cadmium from contaminated land area.
