Summary: With the development of the economy and society, the heavy metal pollution of soils, especially in southwestern China, has become a major environmental concern. This study surveyed the heavy metals in surface soils and crop samples from the Xinping area in Yunnan province, China. New pollution indices were developed to assess the pollution status of heavy metals in both soils and crops. The results showed that while the background level of surface soils was high (62.1%), most crop samples were not contaminated with heavy metals. However, there were some inconsistencies in the assessment between soils and crops, indicating a challenge in the evaluation criteria.

Summary: This study comprehensively assessed the contamination status of agricultural soils in Poland with selected heavy metals using various indicators and statistical analysis. The research results provide insights into the spatial and structural diversification of soil contamination with metals and can be useful for formulating recommendations for soil use and environmental protection.

Summary: Heavy metal contamination in the water body of Changzhao Reservoir is an important issue for water security. This study collected 114 sediment samples to investigate the spatial distribution, risk assessment, and source identification of heavy metals. The concentrations of heavy metals were higher in the surface layer of sediment compared to the middle and bottom layers. pH and Cd were identified as key factors for TOC in the sediment. The proportion of uncontaminated to moderately contaminated Cd, Zn, and As in the surface layer was 84.21%, 47.37%, and 34.21%, indicating the impact of these metals on sediment quality. The dominant source of pollution was identified as agricultural non-point source pollution. Overall, this paper provides insights into the distribution and trends of heavy metals and the protection of the reservoir in the future work.

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 concentration, distribution, sources, and health risks of eight heavy metals in agricultural soils in a long-term zinc smelting area in Guizhou, China. The results showed that lead, cadmium, and arsenic were the most contaminated elements, likely caused by the zinc smelting activities. Children in the study area were found to face greater health risks, both non-carcinogenic and carcinogenic, associated with lead, cadmium, and arsenic.

Summary: The aim of this work was to construct maps of anthropogenic contamination of agricultural soils in Czech Republic by risk elements. Conventional approaches to geochemical maps can only visualize extreme contamination, while weak and/or diffuse contamination requires expert opinion to distinguish natural and anthropogenic factors. Geogenic and lithological anomalies play important roles in understanding contamination sources. Element concentration ratios, such as Co, Cu, Pb, and Zn, can be used to separate geogenic and lithogenic anomalies. Expert opinion is necessary to distinguish anthropogenic contamination from natural variability. The interpretation of geochemical maps and identification of anthropogenic contamination become more complicated in larger and more heterogeneous mapped areas.

Summary: In this study, a corrected method was proposed to estimate the total phosphorus (TP) pollution load, aiming to explore its future variation and develop effective phosphorus pollution control strategies for water environment management. The results showed that the total TP pollution load from diverse sources will increase from 12,194.92 tons in 2021 to 12,461.26 tons in 2025, with an increase of 2.18%.

Summary: The study assessed contamination of nine heavy metals in agricultural, urban, and wetland soils in Western and Rift Valley Kenya. Wetlands were found to be the most polluted due to retaining more heavy metals. While heavy metals did not pose risks via inhalation and dermal contact, ingestion of arsenic presented high risks of cancer for children. Intensive agriculture and urbanization should be closely monitored to prevent further heavy metal pollution.

Summary: A total of 713 research papers on field monitor experiments of heavy metals in farmland and urban soils in China from 2000 to 2019 were obtained and analyzed. The meta-analysis revealed the average concentrations of eight heavy metals in Chinese soils and highlighted the significant increase in cadmium content, as well as the higher level of heavy metal pollution in urban soils compared to farmland.

Summary: Heavy metal elements in farmland soil pose a threat to crops and food security. Hg was identified as the most concerning heavy metal in the farmland soil of Shaanxi Province. Agricultural production activities, transportation, and air pollution caused by coal combustion are the main sources of heavy metal contamination in farmland soil. Therefore, sustainable strategies for heavy metal pollution control and agricultural development should be implemented in different regions.

Summary: This study utilized LA-ICP-MS to determine the concentrations of heavy metals in agricultural soils of Kafr El-Zayat city and assess soil quality. The results indicated that some heavy metal concentrations exceeded global background values and Canadian soil quality guidelines, with a moderate contamination level observed in all sampling sites. Multivariate analysis revealed correlations and sources of heavy metals in agricultural soils, highlighting clustering patterns and principal component analysis explaining a significant portion of variance.

Summary: Limited information is available on the health risks of heavy metals in tea plantation soils, especially the specific sources of contamination. This study used ICP-MS to analyze HMs in tea leaves and topsoil samples. Agricultural activities and natural sources were found to be the main contributors to the non-carcinogenic risks for adults, with Co and Cr being major contributors to non-carcinogenic and carcinogenic risks in tea leaves, respectively.

Summary: This study investigated the extent and sources of heavy metal (HM) contamination in agricultural soils and evaluated pollution and ecological risks using multiple indices. The findings showed that Mn and Cd were major contributors to ecological risks, with Cd identified as the primary concern for soil pollution. Most of the soils were in a natural state, but the contamination risks posed by Cd and Mn raised concerns.
