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: Nowadays, microplastic contamination has been found in various environmental samples, but there have been few recent studies focusing on microplastic contamination in drinking sources and food packages. This review paper briefly summarizes the findings related to microplastic contamination in plastic drinking bottles, tap water, and food packaging containers. The literature shows that different types of microplastic fragments, such as polypropylene, polystyrene, polyethylene terephthalate, polyvinyl chloride, polyethylene, high-density polyethylene, low-density polyethylene, etc., have been detected. Microplastic fragmentation can be caused by mechanical stress, UV radiation, low quality plastic materials, aging, and atmospheric deposition. In addition, microplastics can accumulate various chemical compounds and complex materials from the surroundings, making their accurate detection challenging. The repeated usage of plastic drinking bottles and food containers at the community level can also lead to microplastic leaching and potential health risks. This narrative study highlights the need for more high-quality research in this field to better understand potential exposure to microplastics.

Summary: The migration of 16 phthalate esters (PAEs) in seven different types of water pipes and filter materials was investigated. It was found that the migration of PAEs from plastic pipes into water increases with higher water temperature, lower pH, and longer leaching time. The chronic daily intake of PAEs through drinking water was higher for children aged < 1-12 years than other population groups. The carcinogenic risk of DEHP through drinking water was negligible for most groups, but acceptable for young children aged 1-2 years.

Summary: This article proposes a new method for quantitative chemical risk assessment of CEC mixtures (QCRA(MIX)). Through a case study, the potential of this method is illustrated. The method considers uncertainties in both exposure and hazard assessment to calculate a probabilistic mixture Benchmark Quotient (BQ(MIX)). The results show that the health risks posed by alkylphenols and phthalates in both tap water and bottled water are significant based on overall water consumption.

Summary: A narrative review was conducted to describe the current understanding of microplastic presence in drinking water. The 21 reviewed studies revealed the presence of microplastics in tap and bottled water, raising concerns about potential toxicity. The concentration of microplastics increased with decreasing particle size and was higher in bottled water. Drinking water treatment plants showed a high removal rate of microplastics. This evidence suggests that consumers should opt for tap water over bottled water to reduce exposure to microplastics and minimize plastic waste. The high variability among study results highlights the need for a globally shared protocol to harmonize findings.

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.
