“…Although a scarcity of research into plant based environmental remediation technologies in PICTs currently exists, a few authors including Rungwa et al [51] have highlighted the potential value of phytoremediation for the amelioration of contaminated sites in the region. Among the studies and trials which have explored the use of plants in ameliorating contaminants in the Pacific Islands, the bulk have been small lab-based trials.…”

Effectively dealing with hazardous and recalcitrant pollutants such as heavy metals (HMs) has become a global challenge with limited options available for reprieve. This is true for Pacific Island Countries and Territories (PICTs) which have witnessed significant economic transitions and substantial increases hazardous waste depositions. Although several physico-chemical remediation techniques exist, the economic and geographic limitations of PICTs render them impractical for the region. Phytoremediation, a plant-based remediation technology which exploits hyperaccumulator plants to extract, accumulate and/or stabilize HMs, has received significant interest as a sustainable and non-intrusive remediation option. Nonetheless, improving the application and efficiency of phytoremediation programs not only requires a better understanding of the fundamental mechanisms governing HM accumulation and tolerance in plants, but also demands fast and reliable spectroscopic techniques for in-situ analysis. This review critically examines the current practices in phytoremediation and its prospects for the treatment of HM-contaminated sites in PICTs. We also review the limitations of traditional spectroscopic techniques such as inductively coupled plasma mass spectroscopy/atomic emission spectroscopy (ICP-MS/ AES) and the promise of novel techniques such as field portable X-ray fluorescence spectrometry (FP-XRF), atmospheric pressure discharge plasma (APDP) and lab on chip (LOC) in phytoremediation studies.

“…The results suggested that Cd accumulation in the roots was mainly related to the transportation mode of heavy metal in plants. Most heavy metal ions firstly entered into the plant root cells by the means of root absorbing and then were controlled through specific transport proteins [26]; they were transported through xylem conduit and finally moved to the plant stems and leaves [27,28]. Actually, due to cortical barrier effect, the cortex can help prevent the heavy metal migration between roots and shoots [29].…”

To evaluate the efficacy of biochelators for phytoremediation of cadmium (Cd), effects of biochelators (humic acid, HA; polyaspartic acid, PASP; rhamnolipid, RLs) and synthetic chelator (sodium tripolyphosphate, STPP) on the growth, accumulation, and antioxidant index of Cd were investigated in Iris sibirica L. The results indicated that the addition of HA increased the dry weight of leaves and stems, and the addition of PASP, RLs, and STPP increased the growth of leaves but inhibited the growth of stems. The determination of Cd accumulation indicated that HA decreased the content of Cd in all tissues, while the addition of PASP, RLs, and STPP increased the accumulation of Cd in stems and roots. In addition, the determination of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) activities indicated that the treatment of PASP and RLs increased the activities of antioxidant enzymes, which might be beneficial to the resistance of Cd for Iris sibirica L. Overall, these results indicated that biochelators may improve the phytoremediation efficacy of Iris sibirica L. on Cd polluted paddy field. Among the tested chelators, PASP exhibited the best comprehensive efficacy and the highest commercial potential.

“…Coal mining activities in open spaces in the form of excavation and stockpiling will always face slope stability problems. Slope stability analysis is carried out to assess the level of stability of a slope (6). The term Slope Stability can be defined as the resistance of the block on an inclined surface (measured from the horizontal line) against collapsing and sliding (7).…”

Slope stability is an important factor in the planning and operation of open pits and mines. Currently the company has been mining up to a height of 20 meters. In the implementation of mining activities, the potential for landslides on the side walls of the slopes of sector X occurs on one of the slopes, namely at an elevation of +70 masl. The company made two design choices, one of which was confirmed by researchers in overcoming the potential for landslides. In carrying out slope analysis, information about the general properties of rock mass consists of testing the physical properties of rocks and testing the mechanical properties of rocks. The results of the safety factor analysis of the A-A cross-section with 2.476 saturated MAT (Stable) and dry MAT 3.159 (Stable), while the B-B cross-section with saturated MAT 2.161 (Stable) and dry MAT MAT is 2.771 (Stable). Meanwhile, for the two segments, A-A’ with saturated MAT of 2,459 (Stable) and dry MAT of 3,131 (Stable), while the B-B’ section with saturated MAT of 1,653 (Stable) and dry MAT of 2,464 (Stable). The researcher recommends using option 1 based on the safety factor value which shows a higher value.
