Summary: We propose an analytical workflow scheme for source tracing and risk estimation of lead-contaminated soil, and demonstrate it with test sites in the city of Turku. The workflow includes lead concentration, sequential extractions, mineralogical characterization, and isotope composition. The study found that elevated lead concentrations in urban topsoil samples in Turku mainly originate from fill-derived soils imported from other regions. The use of traditional geochemical study and advanced micro-analytical techniques revealed that lead in urban fill-derived soils is bound to various carrier phases and has multiple pollution sources.

Summary: This study conducted a multidisciplinary analysis on soil, road dust, and house dust samples from a heavy industrial area in Greece, revealing the widespread presence of anthropogenic Fe-containing particles in all sampling media, which are associated with the bioaccessibility of most analyzed elements. By combining magnetic measurements, SEM/EDS analyses, bioaccessibility measurements, and isotopic analyses, it was found that industrial Pb and Pb related to the past usage of leaded petrol are the primary sources of solubilized Pb in simulated gastric and lung extractions.

Summary: The goal of this study was to contribute to a unified approach for assessing the risk to human health of soil ingestion in contaminated sites with high Ni levels. Relationships between in vitro bioaccessibility and in vivo bioavailability of Ni in different soils were analyzed, and the effects of soil physicochemical parameters on trace element availability were considered. The study showed that as soil conditions favored Ni solubility, more of the Ni became bioavailable, regardless of particle size or soil origin.

Summary: Globally, lead (Pb) contamination is a significant issue affecting public health. This study examines the concentrations and isotopic data of Pb in a Pb paint production facility and its surrounding areas. The findings suggest that pollution from the facility has impacted offsite soils, but determining the exact sources of lead contamination is challenging due to overlapping isotopic signatures. An integrated approach that considers site characterization and historical activities is important for determining source attribution.

Summary: Accurate identification of riverine nitrate sources is important for preventing and controlling nitrogen contamination in agricultural watersheds. Water chemistry and stable isotopes were analyzed in a Chinese agricultural watershed to understand the sources and transformations of riverine nitrogen. Results showed that nitrate concentration varied temporally and spatially due to factors such as rainfall and land use. The main source of riverine nitrate was manure and sewage, but the contribution of chemical fertilizers and soil nitrogen increased during the wet season.

Summary: Lead pollution in an urban wetland in Beijing was studied over a period of one year, showing seasonal variations in lead concentrations and sources. While plant bioaccumulation factor was low, indicating limited transfer of lead to plants, translocation factor was high, suggesting active internal transfer within plants. The isotopic compositions indicated that lead pollution in the study area resulted from a mix of geogenic and anthropogenic sources, with vehicle exhaust, crustal rocks, and ore deposits being the primary contributors.

Summary: This study aimed to investigate the relationship between children's exposure possibility, metal concentration, metal bioaccessibility, and soil particle size. Samples were collected from 50 children aged 3-8 years, including hand-adhered soil, environmental soil, and blood samples. The study found that finer particles were preferentially adhered to the hand and that metal concentrations and bioaccessibilities decreased with increasing particle size. The refined exposure model based on hand-adhered soil showed higher exposure levels and stronger correlation with blood lead levels compared to the traditional method.

Summary: Subtidal marine sediments are an important carbon store, and human activities such as bottom trawling and dredging for fish and shellfish can potentially reduce the organic carbon (OC) stores in these sediments. This reduction can be attributed to various factors such as decreased production of flora and fauna, loss of fine flocculent material, increased sediment resuspension and oxygen exposure. However, these reductions can be offset by other factors such as reduced faunal bioturbation, increased off-shelf transport, and increased primary production from nutrient resuspension. Studies investigating the impact of fishing activities on OC stocks have shown mixed results, highlighting the need for more evidence to accurately quantify the effects of anthropogenic disturbance on seabed carbon.

Summary: Inland waters are significant contributors to global N2O emissions, with the highest emissions occurring in reservoirs and areas with high population density and intensive agricultural activities. The global inland-water N2O emission has been increasing over the past century and currently contributes 7-10% to total global N2O emissions. Continuing excessive use of nutrients, dam construction, and the aging of reservoirs will likely lead to persistently high inland-water N2O emissions.
