Summary: In 2019, the Idaho Department of Environmental Quality conducted a data collection program to determine a state-specific bioaccumulation factor (BAF) for inorganic arsenic (iAs), as part of establishing new water quality criteria. The study found no significant relationship between arsenic levels in surface water and fish tissue. However, fish body weight had a significant effect on iAs concentration in fish tissue. The study suggests that commonly used bioaccumulation models may not accurately predict iAs concentrations in fish tissue in natural environments.

Summary: Heavy metals are a concern due to their toxicity, persistence, non-degradation, and bioaccumulation. Most countries do not consider the effects of aquatic vegetables when deriving human health ambient water quality criteria. This study added the intake of aquatic vegetables to the derivation of human health AWQC and assessed the health risk for heavy metals in Taihu Lake. The results indicated that the intake of Brasenia schreberi had a significant effect on the human health AWQC for copper.

Summary: In this study, a non-experimental approach was used to calculate the oral reference dose (RfD) values and investigate the correlation between toxicity, physicochemical characteristics, and chemical structure of pesticides. A prediction model was developed using T.E.S.T software and multiple linear regression (MLR) analysis. The model showed a good accuracy with less than 10-fold and 5-fold difference between predicted and true values in 95% and 85% of the data points, respectively, which improves the efficiency of RfD calculation. The model predictions provide reference values for contaminant health risk assessment in the absence of experimental data. The RfD values of two pesticide substances were calculated using the prediction model to derive human health water quality criteria, and an initial health risk assessment was performed based on the derived criteria using the quotient value method.

Summary: This study assessed the potential of somatic and F+ coliphage methods as routine surface water quality monitoring tools, and the importance of genetic markers for prioritizing pollution sources. Findings suggest that the selection of general fecal indicators for routine water quality monitoring can influence the interpretation of host-associated genetic marker measurements, leading to prioritization of different pollutant sources for remediation. Differences between Great Lake beach and river sites indicate the need for disparate management practices for each water type.

Summary: Thailand was initially impacted by the COVID-19 pandemic and implemented lockdown measures to control the spread of the virus. This study evaluated the long-term air quality improvement resulting from these restrictions and found that the overall air quality index (AQI) improved by 30%. The subindex of most pollutants significantly improved in metropolitan areas, but the changes in human activities were not clearly related to air quality improvement in suburban areas. The overall health risk assessment also decreased due to the reduction of traffic-related pollutants, but remained above recommended limits for adults in all areas.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.
