Summary: This study presents a partition model of a new buffer zone in a small-scale mine area using unmanned aerial vehicle and geostatistical interpolation maps. The boundary line of the buffer zone is determined by comparing the predicted and measured heavy metal concentrations, showing that the new buffer zone effectively reduces the transport of heavy metals from the mining area into the agricultural land.

Summary: This study investigates the spatial and temporal characteristics, pollution levels, and ecological risks of mercury in urban lake waters and sediments in Guangzhou. The results show that the concentration of mercury in lake waters varies seasonally and is higher in the urban center. Meteorological factors such as precipitation, temperature, and vapor pressure have negative effects on the seasonal changes of mercury concentration in water, while air pressure and wind direction have positive effects. Anthropogenic emissions are likely the main source of mercury in lake sediments.

Summary: This study established a comprehensive pollution control framework for agricultural soils in an industrialized part of Zhejiang Province, China, focusing on a suite of heavy metals identified as priorities for pollution control. It found the key role of industrial and traffic activities in heavy metal accumulation, and identified specific influencing factors for different metals, providing a basis for improved accuracy in source apportionment.

Summary: The enrichment factor (EF) is commonly used to determine the source of pollution, but its accuracy is questioned due to the discretion of background value choice. This study assessed the validity of the concerns and found varying heavy metal enrichment in soils based on different background values. Statistical analyses revealed strong positive relationships between clay content, cation exchange capacity, and certain heavy metals.

Summary: The present study evaluated the toxicological effects of sediments collected from Guangzhou waterways and analyzed the influence of land-use configuration on sediment toxicity and heavy metal and arsenic pollution. The results showed that toxicity and chemical composition varied spatially and were related to different land use types. Agricultural and aquacultural activities were found to have the greatest influence on sediment toxicity, while urban land areas were the main source of metal and arsenic pollution. These findings provide essential knowledge for reducing chemical pollution and ecotoxicological risk in sediments.

Summary: Urban soil heavy metal pollution is an important environmental problem. This study used multiple indices to evaluate heavy metal pollution and ecological risk in soil samples from different areas of Guangzhou. The results showed that the soil samples were heavily polluted with heavy metals, and the ecological impact of heavy metals in the vicinity of the landfill was similar to that in city parks.

Summary: The study investigated the levels of heavy metals in Maltese soil and their potential ecological and human health risks. The results showed low concentrations of heavy metals, with the exception of Zn, which posed a moderate/strong contamination but had low overall potential for ecological risk. The study concluded that the fields examined were not significantly contaminated and did not pose a risk to human health.

Summary: This study investigated the occurrence, spatiotemporal distribution, and ecological risks of seven selected neonicotinoid insecticides (NEOs) in the Wuchong Stream in Guangzhou, China. The concentrations of NEOs in the water samples ranged from 0.97 to 175.92 ng.L-1 in the dry season and 3.15 to 312.92 ng.L-1 in the wet season. The results indicated that NEOs were likely to biologically impair the urban stream ecosystem, especially in the dry season. The residentidal district and farmland area were the main socioeconomic factors affecting the ecological risk of NEOs in the Wuchong Stream basin.

Summary: This study assesses the heavy metal pollution in urban and peri-urban soils in and around Setif city, eastern Algeria. The results show that zinc and lead concentrations exceed the Chinese background values, posing a significant threat to human health. Vehicle emissions, industrial emissions, and uncontrolled waste landfill are identified as the main sources of pollution. The study highlights the need for measures to mitigate heavy metal pollution in Setif city and emphasizes the importance of a sustainable development plan to ensure optimal future environmental conditions.

Summary: The study found that long-term irrigation with wastewater led to the accumulation of heavy metals in the soil, as well as a significant increase in electrical conductivity, organic matter, and nutrient availability. The micronucleus assay revealed a significant increase in micronucleus frequency in soils irrigated with wastewater compared to those irrigated with fresh water, which was correlated with the available fraction of heavy metals in the soil.

Summary: The ecological and human risks of crude oil-associated heavy metals (HMs) in contaminated agricultural lands were assessed using various indices. The results indicated a high environmental risk of crude oil-associated HMs, with Mn > Zn > Cr > Ni > Cu being the most contaminated metals. Furthermore, the study analyzed the adverse effects of these HMs on soil biological properties.

Summary: The study aimed to explore the spatial determinants of heavy metal pollution in agricultural soil in the Sunan economic region of China. The results showed that heavy metal pollution was mainly influenced by accessibility, agricultural inputs, and the composition and configuration of agricultural landscape, with significant heterogeneity over space and farming practices. The study provides valuable insights into understanding the human-land interrelationship in rapidly developing areas.

Summary: This study explores the response mechanism of sediment magnetic properties to glacial-area variation caused by climate change. It finds that the sediment magnetic properties of alpine lakes are sensitive to glacial-area variations, particularly those caused by air-temperature change. Monitoring sediment magnetic properties can be used to track variations in glacial area.
