<![CDATA[Marparan village in Sampang, Indonesia uses a communal rainwater harvesting system (RWHS) for collecting water during the dry season. This study aimed to assess the quality of the water in the communal rainwater catchment pond (CRHP) and investigate the occurrence of contact dermatitis among the community members. The research followed an observational approach with a cross-sectional design, involving 50 individuals randomly selected from the user community of the CRHP for sanitation hygiene purposes. Water samples were collected from the CRHP and analyzed for physical characteristics, pH level, and surfactant content. The results revealed that the water in the communal rainwater storage pond did not meet the quality standards established by the Ministry of Health Indonesia. Additionally, a significant association was found between age and the occurrence of contact dermatitis. However, no significant relationships were observed between variables such as activity type, exposure frequency, and the incidence of contact dermatitis. Moreover, no relationships were identified between activity type, exposure frequency, duration of exposure, and the occurrence of contact dermatitis. It was observed that respondents did not rinse with clean water after using the communal rainwater storage pond for bathing or washing clothes. Therefore, it is recommended that individuals rinse with clean water after engaging in activities involving the use of the rainwater storage pond to minimize the risk of contact dermatitis.]]>

<![CDATA[The detection of microplastics in the water and sediment samples of the landlocked countries in central and eastern Asia means the relatively less populous countries are not spared from microplastic pollution. It is crucial to understand the severity of microplastic pollution in and near those countries since there are significantly fewer regional studies on microplastic pollution conducted for those countries. This review aims to systematically present the occurrence and characteristics of microplastics in and near the landlocked countries to shed light on the severity of microplastic pollution therein. It analyzed the contents of more than 38 papers to achieve its aim. Of all the landlocked countries, Mongolia has the most studies on microplastic pollution, while there are none for Turkmenistan, Afghanistan, Uzbekistan, Kyrgyzstan, and Tajikistan. For dried sediment samples, the microplastic contents ranged from 862 items/kg in the Tuul River of Mongolia to 15–46 items/kg on the Iranian side of the Caspian Sea near Turkmenistan. Lake Hovsgol in Mongolia recorded a microplastic density of 20,264 items/km2, whereas the Selenga River system had a mean microplastic density of 120.14 items/km2. Microplastics concentrations in the Caspian Sea varied, with areas near the southwest of Turkmenistan having microplastics concentrations ranging from 0.000246 items/l to 0.710 items/l. The microplastics levels in the countries are comparable to those of other regions in the world, indicating the impacts of human activities on microplastic pollution. Some microplastics might also have entered the countries through long-range transport by air and water from areas of higher human activity.]]>

<![CDATA[Bisphenol A (BPA) is recognized as an endocrine disruptor, capable of interfering with the normal functioning of hormones within the body by mimicking the effects of estrogen. Drinking water is one of the most common pathways of exposure to BPA as it can permeate plastic products and other materials, entering water sources. This article presents a comprehensive overview of BPA, including its incidence, origins, environmental fate, its impact on human health, and the role of fungi in the biodegradation of BPA. Fungi are natural decomposers, capable of breaking down organic compounds, including BPA, under suitable conditions. Studies have demonstrated that specific species of fungi can effectively biodegrade BPA. Some fungi utilize ligninolytic enzymes, such as laccases and peroxidases, to break down the phenolic rings of BPA. Other fungi employ non-ligninolytic enzymes, such as esterases and hydrolases, to cleave the ester linkages in BPA. Furthermore, some fungi can break down BPA via cometabolic pathways, whereby the chemical is degraded as a side reaction to the degradation of another substrate. The use of immobilized enzymes for BPA degradation has also demonstrated potential. Immobilized enzymes are those that are attached to a solid support, such as a polymer or matrix, allowing them to be used multiple times and enhance their stability and catalytic activity]]>

<![CDATA[The microbiological and physicochemical properties of bore-hole waters from water reservoirs in selected hostels in ifite-Awka metropolis were evaluated. Five (5) bore-hole water samples from stored-water tanks were evaluated to ascertain the physicochemical parameters, presence and population of different bacterial and fungal groups. Total heterotrophic bacterial (THC) counts ranged from 1.20x103 cfu/ml to 6.5x103 while the fungal counts spanned from 2.5x103 cfu/ml to 8.9x103 cfu/ml. Bacteria obtained from the borehole waters include Salmonella spp., Escherichia coli and Shigella spp. E. coli was the most prevalent with MPN 380/100 ml of water reported in sample A while Shigella sp. was the least prevalent with MPN 130/100 ml of water reported in samples B and E. Fungal isolates obtained include Aspergillus species, Candida species, Acremonium species and Cladosporium species. E. coli and Aspergillus spp. were predominant than other isolates. The pH ranged from 6.65 to 7.47; hardness ranged from 92 mg/l to 156 mg/l and Iron concentration ranges from 0.267 ppm to 0.378 ppm, phosphate contents ranged from 2.375 to 6.125 while Nitrate contents ranged from 1.071 to 6.214. The presence of these organisms in water meant for municipalities indicates faecal contamination. This calls for improved sanitary conditions of reservoir tanks in these locations and beyond.]]>

<![CDATA[Earlier research demonstrated the efficacy of microbial fuel cells in both wastewater treatment and renewable electric current generation. In this process, microbial fuel cells harness the potential of wastewater as a substrate and energy source, enabling microorganisms to generate electric current. Introducing microorganisms sourced from septage sludge acts as a microbial catalyst. Additionally, tofu wastewater is employed as a nutritional resource to support the growth of these microorganisms. A dual-chamber reactor was utilized to carry out this study, featuring an anode and a cathode connected through a salt bridge. Various substrate variations were performed on the anode, specifically with a combination of tofu liquid waste and septage sludge at ratios of 1:1, 1:2, and 1:3. Additionally, different electrolyte solutions, such as KMnO4 and K3(Fe(CN)6), were used at the cathode. Using different electrolyte solutions as electron acceptors can enhance the electric current production generated. The study spanned 240 hours of operation, during which electric current, voltage, COD, and BOD measurements were taken at 48-hour intervals. The findings revealed that including septage sludge in a 1:3 ratio yielded the highest current strength compared to other substrate variations, measuring 16.34 mA. When using a 0.25 M KMnO4 as an electrolyte solution, the voltage recorded was 8.78 V. Additionally, the most effective removal of COD and BOD content was achieved with a substrate ratio of 1:3 in the presence of KMnO4, achieving removal rates of 95.12% and 96.45%, respectively. These results indicate that adding septage sludge contributes to increased electricity current production.]]>

<![CDATA[The increasing emphasis on sustainability has led many nations to introduce ESG-related regulatory frameworks. These frameworks aim to regulate and guide financial investments based on the ESG performance of companies while ensuring transparency to prevent the manipulation of sustainability-related information concerning investment products. This article reviews the regulatory and disclosure frameworks implemented in different nations and regions to identify their key components. The review reveals that these regulatory frameworks capture the environmental aspects encompassing climate change adaptation and mitigation, identification, evaluation and management of climate risks, circular economy practices, and pollution prevention. They also cover the social aspects, which include community development, employee welfare, and human rights. Additionally, governance aspects comprising anti-corruption measures, diversity within company boards and management, and the implementation of due diligence were included. The increased emphasis on transparency underscores the importance of disclosure. In this regard, the disclosure frameworks largely align with the recommendations of the Task Force on Climate-related Financial Disclosures, which cover governance, strategies for identifying and assessing risks and opportunities, their impacts on a company's finances and operations, resilience-building through scenario analyses, risk management integration with the overall organizational risk management, and the use of metrics and targets to measure performance. Malaysia could benefit from adopting comprehensive regulatory and disclosure frameworks that address ESG holistically, with elements related to the circular economy and dual materiality included in the frameworks. Future studies could focus on standardizing the development of metrics and targets to facilitate performance comparisons.]]>

<![CDATA[The Agboyi River in Lagos, Nigeria provides important ecosystem services; however, anthropogenic activities are polluting the river, necessitating periodic monitoring. This study assessed the heavy metal content (lead, cadmium, chromium, copper, and arsenic) in water samples from the river. Additionally, we evaluated various physicochemical parameters, including pH, total dissolved solids (TDS), conductivity, hardness, magnesium, calcium, chloride, sulfate, and nitrate. The values of each heavy metal were used to calculate human average daily ingestion (ADI), average daily dermal exposure (ADDE), hazard quotient (HQ), and carcinogenic risk (CR). The physicochemical analysis revealed non-permissible levels of TDS, electrical conductivity, alkalinity, hardness, magnesium, calcium, sulfate, nitrate, chloride, and phosphate. The heavy metal analysis showed intolerable levels of lead, arsenic, cadmium, chromium, and copper. The ADIs for the heavy metals were within the recommended dietary intake (RDI), but their ADDEs exceeded the RDI, except for chromium. The HQ and CR for all heavy metals exceeded recommended limits. Seasonal variations were observed in the physicochemical parameters, with TDS, turbidity, acidity, nitrate, and phosphate being higher in the wet season, while other parameters were higher in the dry season. The water poses health hazards to users, indicating the need for river remediation.]]>

<![CDATA[This study assessed the phytoremediation potential of sunflowers for removing cadmium from the soil around a paint manufacturing industry in Eleyele, Ibadan. Background levels of Cd in the topsoil and subsoil were determined. The site was divided into two plots. Organo-mineral fertilizer (OMF) was applied to the first plot, which served as the experimental plot, while the second plot was without OMF and served as the control. Concentrations of cadmium in the plants were determined using an Atomic Absorption Spectrophotometer. Baseline mean Cd contents were 29.23 mg/kg and 33.30 mg/kg for topsoil and subsoil, respectively. Over the planting period, the sunflower plants removed 53.1% and 51.6% of Cd from the topsoil and subsoil in the test plot, while 40.65% and 47.80% were removed from the topsoil and subsoil, respectively, in the control. Cd absorption from the contaminated soils was found to be translocated to all parts of the sunflower. The concentrations of Cd in the sunflower parts were as follows: root system (10.70 mg/kg), shoot (8.17 mg/kg), leaves (6.43 mg/kg), and seeds (2.52 mg/kg) for the test plot. For the control plots, Cd in the root, shoot, leaves, and seeds were 7.60 mg/kg, 7.43 mg/kg, 4.75 mg/kg, and 2.03 mg/kg, respectively. The study confirmed that sunflowers have the potential to remediate Cd from contaminated soil, and this potential was enhanced by the application of OMF.]]>

<![CDATA[Following phytoremediation, the disposal of accumulating plants (phytoaccumulators) is challenging because the accumulated metals could leach back into the soil if not properly managed. Therefore, this study aims to use calcined clay (CC)-based geopolymer to stabilize Pb, Cu, and Zn in a phytoaccumulator (Sporobolus pyramidalis) ash (PA). Additionally, the effect of adding PA on the setting time, mechanical and heavy metals leaching properties of the geopolymers was investigated, to determine their environmental suitability and potential applications. Mixed proportions of CC (85-100%) and PA (5% - 15%) were used to produce geopolymers, using 8 M NaOH/Na2SiO3 (1:1) as an alkaline activator. The geopolymers were cured for 7 and 28 days at ambient temperatures. Thermograms showed the dehydroxylation of kaolinite at 450-650 °C. X-ray flourescene (XRF) analysis showed CC’s predominant oxides as SiO2 (53.1%) and Al2O3 (41.4%), while PA exhibited SiO2 (46.6%), CaO (13.8%), PbO (1.30%), ZnO (0.28%), and CuO (0.04%). Thermal treatment eliminated most FTIR bands associated with kaolinite, converting crystalline kaolinite into amorphous metakaolinite. Geopolymer setting time ranged from 75 min (100% CC) to 111 min (85% CC). Furthermore, elevated Cao content in the PA resulted in the geopolymer’s early strength development. However, the compressive strength decreased as PA quantity increased, with 95% CC-PA exhibiting maximum strength (22.5 ± 0.2 MPa) after 28 days. Further tests confirmed that 95% and 90% CC-PA geopolymer effectively stabilized Pb and Cu. Fabricated geopolymers met the ASTM (C62-17) Specification Standard for building brick, indicating their suitability as a waste-based construction material under controlled conditions.]]>

<![CDATA[Chlorpyrifos (CP) is a widely used organophosphate pesticide known for its recalcitrant nature, raising concerns about potential ecological and health impacts due to its toxicity. Many plants and animals are contaminated with this pesticide. Microbial biodegradation offers an environmentally friendly and effective method to remove CP from the environment and mitigate its impacts, especially given its low cost, particularly when bioremediation is conducted on-site. Different types of microbial species have been found to function under various environmental conditions, with some, like Pseudomonas nitroreducens PS-2 and Pseudomonas aeruginosa (NCIM 2074), showing promising results with degradation rates of up to 100%. However, challenges exist, such as partial degradation caused by the presence of metabolites, and the recalcitrant nature of CP, which can impede microbes' ability to effectively degrade its hydrocarbon ring. Overall, a combination of approaches, such as microbial and algal methods, or the discovery of new microbial strains, can help overcome these challenges and further enhance the long-term viability of this technique.]]>
