Summary: In Asian developing countries, undeveloped and ineffective sewer systems are causing surface water pollution by pharmaceuticals and personal care products (PPCPs), posing risks to freshwater fauna. This study aimed to assess the contamination status, bio-accumulation, and potential risks of PPCP residues in surface water and freshwater fish from three Asian countries. Results showed that bioaccumulation factors measured in fish and water samples were in close agreement for the majority of compounds, but certain species-specific differences were observed. The presence of certain PPCPs in fish plasma and surface water indicated potential adverse effects on wild fish and high ecological risks on Asian freshwater ecosystems.

Summary: This study investigated the occurrence of 187 pharmaceuticals and personal care products (PPCPs) in bottled water samples, with 44 compounds belonging to 14 PPCP categories detected. The thermal stabilities of the PPCPs were determined, revealing that only 35 out of the 187 compounds were degraded significantly after boiling for 5 minutes. Despite low risk levels overall, certain PPCPs showed higher risk levels in infants compared to other life stages, highlighting the need for further research on the toxicity of PPCP mixtures and their effects on human intestinal microbiota.

Summary: In many nations and locations, the presence of pharmaceuticals in groundwater and surface waters is a growing concern due to their potential impact on aquatic ecosystems and public health. This review summarizes the research evidence regarding the occurrence, impact, and fate of pharmaceuticals in different water bodies. Various analytical techniques, such as LC-MS, HPLC, UPLC-MS/MS, and GC-MS, have been used to detect and analyze pharmaceuticals in water bodies, with LC-MS being the most commonly used instrument. Sulfamethoxazole, an antibiotic, was found to be the most frequently detected drug in wastewater, while antibiotics, in general, were the most reported pharmaceutical group.

Summary: The study identified and quantified ten psychoactive substances and metabolites in 217 surface water samples collected across China. Caffeine, paraxanthine and cotinine were found to be ubiquitous in the monitored sites, with high concentrations of diet-related drugs occurring in areas with high population densities. Traditional drugs tended to occur in megacities and the illegal manufacturing bases of illicit drugs, while emerging drugs were popular throughout the country. Risk assessment results indicated no potential human health risk from drinking water containing these substances.

Summary: Land use/land cover changes have significant impacts on water resources, and studying these impacts is crucial for watershed management. In the Upper Prek Thnot watershed, there have been notable changes in land use, resulting in alterations in runoff, groundwater, water yield, percolation, and evapotranspiration. The conversion of forest to agricultural land has particularly significant effects on these hydrological components, highlighting the need for a sound strategic management plan to ensure the sustainability of ecosystem services in the watershed area.

Summary: This study analyzes the presence and potential risks of microplastics in eight major bottled water brands in Malaysia. The results show that the concentration of microplastics in these bottled water samples is low, with particle sizes mainly ranging from 100 to 300 micrometers. Transparent microplastics are the most prevalent. The study finds that microplastics in bottled water mainly come from packaging materials and bottle caps. Although the estimated dietary intake values are low, the presence of plastic additives and residual monomers in these particles emphasizes the potential risks to human health.

Summary: The aim of this research is to investigate the occurrence, characteristics, and potential sources of microplastic pollution at four agricultural farms in Malaysia's tropical region of Klang Valley. The mean number of microplastic particles found in the agricultural soils were 2.1 +/- 0.44 to 3.4 +/- 1.2 particles/kg. Farms B and D had the lowest and highest total microplastic particle counts, 1.5 and 6.0 particles/kg, respectively, which was in line with the intensity of plastic consumption at these farms. These findings confirm the presence of microplastic pollution in Tropical agricultural soils and highlight the need to evaluate the negative impacts of long-term plastic use on agricultural soils.

Summary: This study used value chain analysis to examine the sustainability of the fuelwood value chain in Yobe, Nigeria, in relation to economic, environmental, and social aspects. The findings revealed that registered licensed actors and non-licensed actors were involved in fuelwood business activities. Profit distribution along the value chain was unequal, with 65% of the total profits going to transporters. Natural forests served as the main source of fuelwood, and there were 18 preferred tree species commonly traded. Women had limited participation in the formal fuelwood value chain, mainly concentrated in the informal sector. The study's findings can inform policymakers on enhancing sustainability in terms of profit sharing, forest resource exploitation, and gender equality.

Summary: Suitable extraction technique and least cost with reduced environmental impact are the main concerns in timber transportation planning in undulate topography. Two types of extraction machines are combined for timber harvesting in Malaysia, aiming for each machine to extract timber suitable to their ability. A Bees Algorithm (BA) is proposed to find the optimal TTP for timber extraction, forest road, and landing locations with grid cell-sized 10 m x 10 m and assigned fixed and variable costs. The results favor the log fisher as a preferable extraction technique with lower total cost compared to the crawler tractor. The model identifies a suitable timber extraction technique and estimates the extraction costs, while further studies are required for comparing BA with other optimization methods to achieve better results.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
