Summary: This study investigated the occurrence and seasonal variation in concentrations of emerging organic contaminants (EOCs) in shallow groundwater underlying two peri-urban areas of Bwaise and Wobulenzi in Uganda. The study found antibiotics, hydrocarbons, and pesticides in the groundwater, posing potential ecological effects at long-term exposure. Monitoring and mitigation of associated risks are recommended for both highly and moderately urbanised catchments.

Summary: Children are frequently exposed to various environmental contaminants, and the effects on health outcomes are still not well understood. Fecal samples provide a non-invasive and direct assessment of gut microbiome exposure to contaminants. This study analyzed organic compounds and elements in the feces of middle-class, semi-urban children in Eastern Canada, and found that most targeted compounds and elements were detected, with caffeine and acetaminophen being the most common substances.

Summary: Groundwater serves as a crucial source of drinking water for a large portion of the population, but it is often contaminated. Biochar has emerged as a promising solution for treating groundwater and removing pollutants. However, research on the practical application and efficacy of both pristine and modified biochar for groundwater treatment is limited.

Summary: Concerns about groundwater contamination in China have increased due to the growing demand for fresh water and economic development. This study examines the vulnerability of aquifers to hazardous substances in a rapidly urbanizing city, Xiong'an New Area. The researchers collected groundwater samples and identified various emerging organic contaminants (EOCs). They found significant aggregation of EOCs along the Tang River, mainly due to historical residue and accumulation from wastewater storage. The study highlights the importance of controlling groundwater pollution and ensuring drinking water safety in rapidly urbanizing cities.

Summary: Gas emitted from landfills contains a large quantity of volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs), some of which are carcinogenic, teratogenic, and mutagenic. The global hazards of VOCs and SVOCs in landfill gas to human health remain unclear. To quantify the global risk distributions of these pollutants, the composition and concentration data of VOCs and SVOCs from 72 landfills in 20 countries were collected and their human health risks were assessed. Organic compounds in landfill gas primarily result from the biodegradation of natural organic waste or the emissions and volatilization of chemical products. The respiratory system, particularly the lung, was found to be the major target organ of VOCs and SVOCs, with additional adverse health impacts ranging from headache and allergies to lung cancer. Aromatic and halogenated compounds were the primary sources of health risk, while ethyl acetate and acetone from the biodegradation of natural organic waste also exceeded the acceptable levels for human health. Overall, VOCs and SVOCs affected residents within 1,000 m of landfills. Air temperature, relative humidity, air pressure, wind direction, and wind speed were the major factors that influenced the health risks of VOCs and SVOCs. Currently, landfill risk assessments of VOCs and SVOCs are primarily based on respiratory inhalation, with health risks due to other exposure routes remaining poorly elucidated. In addition, potential health risks due to the transport and transformation of landfill gas emitted into the atmosphere should be further studied.

Summary: Groundwater as a major source of fresh water in semi-arid regions is facing severe threats from pollutants such as dissolved organic matter (DOM) and heavy metals, which are caused by human activities. This study conducted research on shallow groundwater samples from the Guanzhong basin in China, and found that DOM and heavy metals in groundwater are influenced by each other. Additionally, the presence of DOM in groundwater strongly affects the bioavailability, migration, and transformation of manganese.

Summary: This study evaluated the quality of urban shallow groundwater in Cangucu town using water quality indexes and multivariate statistical analysis. The results showed that the groundwater is not safe for drinking without disinfection and several physicochemical parameters did not comply with the WHO guideline limits. The drinking groundwater quality index indicated that 55% of the samples had good to excellent water quality, 25% had poor water quality, 15% had very poor water quality, and 5% were considered unsuitable for drinking purposes. Multiple linear regression analysis identified sodium, pH, manganese, potassium, and calcium as the variables that contributed most to the groundwater quality index results. Principal component analysis revealed that the ion exchange process predominantly controls groundwater chemistry in the area. This study is the first investigation of shallow groundwater quality in Cangucu town and highlights the urgent need for pre-treatment of groundwater and the serious hazard of drinking untreated water.

Summary: Volatile and semi-volatile organic compounds (VOCs and SVOCs) can enter leachate from landfilled wastes and require appropriate treatment before discharge. Solubility is a key factor driving the entry of VOCs and SVOCs into leachate, and different treatment processes have varying effectiveness in removing these compounds.

Summary: The endocrine-disrupting effects caused by wastewater discharging on aquatic organisms have raised extensive concerns. In this study, the efficiency of various wastewater treatment processes in removing estrogenic activity was evaluated, and the association with organic micropollutants was investigated. It was found that the effluents from all the treatment plants exhibited estrogenic effects, and certain semi-volatile organic compounds were significantly correlated with the estrogenic activity in the effluents.

Summary: Excessive application of phosphorus fertilizers in agricultural regions has led to the accumulation of phosphorus in soil profiles, becoming the main source of phosphorus in groundwater. Elevated phosphorus concentrations in groundwater are a global phenomenon, posing significant challenges to the safe use of water resources and the aquatic environment. Currently, there is limited research on predicting phosphorus concentrations in groundwater compared to nitrate nitrogen.

Summary: The impact of different woody plants on nitrogen distribution in stormwater green infrastructures is still not well understood. This study found that rainfall conditions such as inflow concentration, recurrence interval, and number of dry days can influence the distribution of NH3-N and NO3-N in the soil. The study also established a quantitative relationship between N pollutant load reduction rates and influencing factors, which can be used to estimate the effectiveness of green infrastructure in treating runoff pollutants.

Summary: This review critically examines the role of plants in nitrogen migration and transformation in plant-soil systems, focusing on the influence mechanism and interdependent relationships among plant roots, plant metabolism, plant root exudates, and rhizosphere microbes. While there is abundant information regarding the influence of microorganisms on nitrogen migration and transformation, there is limited knowledge on the effects of different plant root characteristics and root exudates. Additionally, there are major knowledge gaps regarding quantitative pathways of nitrogen migration and transformation by deep-rooted plants to mitigate negative environmental impacts. Further research is needed to understand the comprehensive influence of multiple environmental factors on plant-soil systems for more effective soil and plant management.

Summary: With the acceleration of urbanization, N pollution in rainfall runoff has become the primary cause of eutrophication. Green infrastructure (GI) has been implemented to control N pollution, but little is known about the process through which woody plants affect N distribution and the microecosystem in GI. Laboratory tests were conducted to investigate the roles of Sophora japonica and Malus baccata in N removal in a column-scale GI. The results showed that M. baccata had a greater impact on N distribution and microecosystem due to its higher abundance of Actinobacteria and higher enzyme activities.
