Summary: A novel passive sampler technique using Oleic acid-embedded cellulose acetate membranes (OECAMs) was developed to evaluate the bioavailability of epoxiconazole (EPO) to earthworms. The study found a significant linear relationship between EPO concentrations in earthworms and OECAMs, with OECAMs reaching equilibrium for EPO sampling within 2 days. Additionally, EPO concentrations in soil porewater, earthworms, and OECAMs were lower in soils with higher organic matter content, showing good potential for OECAMs as a passive sampler for evaluating EPO bioavailability.

Summary: Sediment porewater dialysis passive samplers, or peepers, are containers that capture chemicals in sediment and allow for analysis of their concentrations. Despite over 45 years of research, there are no standardized methods, hindering routine regulatory decision-making. Improvements can be made by optimizing volume and membrane geometry, addressing uncertainties related to oxygen presence, and developing pre-equilibration sampling methods. Standardization of peeper methods is crucial for measuring porewater concentrations at contaminated sediment sites.

Summary: This research compared direct porewater extraction and passive sampling for measuring the freely dissolved concentration of hydrophobic pollutants in sediment porewater (C-pw). The results showed that the direct water extraction method accurately quantified C-pw for low to moderately hydrophobic compounds and could assess the toxicity of PAHs. However, it may have detection limit challenges for strongly hydrophobic pollutants. A new extrapolation approach was proposed to address the uncertainty of C-pw measurement for strongly hydrophobic compounds.

Summary: Bioaerosols are airborne particles of biological origin that have important environmental and health effects. Passive bioaerosol samplers, although less commonly used, offer advantages such as simplicity, low cost, and long sampling duration. This review discusses different types of passive samplers, their collection mechanisms, advantages and disadvantages, and sample analysis methods. Gravity-based and electrostatic-based samplers are explored, along with passive opportunity samplers using preexisting airflow. Passive sampling technologies are inexpensive and provide valuable information about bioaerosol presence and diversity over extended time scales. The use of passive samplers alongside active collection devices can provide a more comprehensive understanding of biological presence and dynamics.

Summary: Dermal sorption is an important exposure route for organic chemicals in consumer products, but migration of these chemicals to sweat has been overlooked. This study used an in vitro simulation model to assess migration of PAHs, PAEs, and BTs from consumer products to sweats, finding differences in migration ratios among different mouse pad materials and identifying key parameters for further investigation. The study also found that daily exposure doses of PAEs and BTs exceeded literature data, with potential non-carcinogenic effects from PAEs in leather mouse pads. Overall, the established in vitro simulation model provides a feasible alternative for assessing dermal exposure risk from consumer products.

Summary: Understanding the particle size distribution and size-resolved gas-particle partitioning of semi-volatile organic compounds (SVOCs) is crucial for determining their fate in the atmosphere. However, previous studies have not adequately considered the size-resolved gas-particle partitioning characteristics of SVOCs. To address this gap, this study collected samples of gaseous and size-fractioned particulates from various indoor and outdoor locations in a megacity in South China. The results revealed that emission sources, physicochemical properties, and environmental conditions significantly influenced the distribution patterns and particle size distribution of SVOCs. Additionally, a new model was developed to predict the size-resolved gas-particle partitioning of high molecular weight PAHs based on their subcooled liquid-vapor pressures and particle size.

The study found that the addition of activated carbon at doses of 8-36% significantly reduced the concentrations and diffusion fluxes of the target chemicals in sediment porewater. A model was developed to estimate the required activated carbon dose for effective sediment amendment based on diffusion flux and sediment concentration. The feasibility of the model was demonstrated using contaminated sediment in an e-waste recycling zone.

Summary: This study collects particles from different sources and measures the inhalation bioaccessibility of polycyclic aromatic hydrocarbons (PAHs) using an in vitro method. The bioaccessible fractions of PAHs were found to be 35-65% for smoke-type charcoal, 24-62% for smokeless-type charcoal, and 44-96% for cigarettes. Machine learning analysis showed that chemical hydrophobicity was the most significant factor affecting the bioaccessibility of PAHs, followed by organic carbon and elemental carbon contents. Particle size had little effect on the bioaccessibility of PAHs.

Passive samplers have emerged as an attractive alternative for monitoring POPs. Deployments of passive samplers at globally distributed sites showed variations in POPs concentrations, with some compounds displaying higher concentrations in specific regions. These results contribute to our understanding of the global distribution and transport of organic pollutants in aquatic systems.

Summary: This study reviews the spatiotemporal patterns of water quality and organic contaminants in drinking water sources in China and explores the relationship between them and total cancer incidences. The findings suggest that the improvement of water quality has had a positive effect on reducing the incidences of water-related diseases and digestive system cancers. Although the cancer risk from exposure to organic contaminants in water is lower than the latest cancer incidences, their similar spatial patterns indicate that this exposure should be considered as a potential factor for carcinogenic risks.
