Response and capability of Scirpus mucronatus (L.) in phytotreating petrol-contaminated soil.
TL;DR: The greenhouse phytotoxicity experiment was conducted to analyse and assess the capability of Scirpus mucronatus (L.) in tolerating and removing petrol in contaminated soil and confirmed that petrol was absorbed by the plant, as shown by the increased carbon content in the plant's root and stem after the treatment.

TL;DR: This paper emphasizes the considerable potential of valuable material recovery from the aquaculture effluent using a combination of bio-coagulant/bio-flocculant utilization and constructed wetland to achieve cleaner production for the Aquaculture sector.
Abstract: Fisheries, one of the growing sectors in Malaysia, contribute a notable percentage to the national gross domestic product. The fisheries sector rapidly and dynamically grew throughout the past three decades. Aquaculture commodities are currently providing remarkable contributions to the fisheries sector, overcoming the previous dominance of traditional marine capture commodities. The fisheries sector is facing environmental issues, especially considering water-related pollution, despite its contribution to the economic sector. Aquaculture effluents contain high organic materials, nutrients, proteins, and even contaminants of emerging concern. Several studies have already been conducted to treat the generated wastewater. However, investigations on environmentally friendly technology, which might lead to resource recovery from aquaculture effluent, are still limited and scarce. This review paper comprises the development of aquaculture in Malaysia, its potential of generating abundant amounts of wastewater, and its characteristics. This paper summarizes the best practice of aquaculture effluent treatment and also highlights the green technology, which can be utilized to overcome the issue of currently utilized physico-chemical treatment. In addition, this paper emphasizes the considerable potential of valuable material recovery from the aquaculture effluent using a combination of bio-coagulant/bio-flocculant utilization and constructed wetland to achieve cleaner production for the aquaculture sector.

TL;DR: In this article, the characteristics of the CaO produced via calcination process at different temperature and calcination time were analyzed and the Fourier transform infrared spectroscopy (FTIR) result showed that the spectrum of 2513 cm-1 as an indication of the C-H group containing CaO appearing after calcination.
Abstract: Seashells waste is abundant in coastal area, especially in the locations where fisheries are a major occupation. This abundant resource of seashells opens a new opportunity further utilization. Seashells waste is a source of CaCO3, which may be converted into CaO via the calcination process. This study analyzed the characteristics of the CaO produced via calcination process at different temperature and calcination time. The calcination process was carried out at a temperature of 800°C, 900°C, and 1000°C with variation of 2, 3, and 4 hours in time. The Fourier transform infrared spectroscopy (FTIR) result showed that the spectrum of 2513 cm-1 as an indication of the C-H group containing CaO appearing after calcination. The FTIR results suggest that the calcination time did not gave major alteration to the functional groups. The results of X-ray diffraction (XRD) analysis showed that CaO laid at the angle of 58.1o and 64.6o. Scanning Electron Microscopy–Energy Dispersive X-Ray Spectroscopy (SEM-EDS) results showed that the most significant compositional outcome after the calcination process was Ca and O at all temperatures and calcination times. All calcined seashells showed rough surface and irregular shape particles. The result of a Thermogravimetric analysis (TGA) suggested that the highest mass alteration occurred at a temperature of 800°C with 78 mins of calcination time.

TL;DR: In this article, the authors compile some information about heavy metals of arsenic, lead, and mercury (As, Pb, and Hg) sources, effects and their treatment and also review deeply about phytoremediation technology, including the heavy metal uptake mechanisms and several research studies associated about the topics.
Abstract: Heavy metals are among the most important sorts of contaminant in the environment. Several methods already used to clean up the environment from these kinds of contaminants, but most of them are costly and difficult to get optimum results. Currently, phytoremediation is an effective and affordable technological solution used to extract or remove inactive metals and metal pollutants from contaminated soil and water. This technology is environmental friendly and potentially cost effective. This paper aims to compile some information about heavy metals of arsenic, lead, and mercury (As, Pb, and Hg) sources, effects and their treatment. It also reviews deeply about phytoremediation technology, including the heavy metal uptake mechanisms and several research studies associated about the topics. Additionally, it describes several sources and the effects of As, Pb, and Hg on the environment, the advantages of this kind of technology for reducing them, and also heavy metal uptake mechanisms in phytoremediation technology as well as the factors affecting the uptake mechanisms. Some recommended plants which are commonly used in phytoremediation and their capability to reduce the contaminant are also reported.
