Summary: The study demonstrates that PTE pollution in road dust is prevalent across China, with levels generally higher in eastern cities than western cities. The main driving factors are socioeconomic, contributing to ecological and human health risks, particularly in southeastern coastal areas and the Beijing-Tianjin-Hebei region. Regions in western China may have potential noncarcinogenic risk from Cd and Pb, necessitating monitoring and control measures.

Summary: The study found that industrial foundry workers are exposed to multiple potentially toxic elements, with some workers having high concentrations of arsenic and cadmium. The concentration of these elements in different biological samples is significantly influenced by work tasks and employment years. This occupational exposure is associated with both carcinogenic and noncarcinogenic risks.

Summary: This study proposes a nonlinear canonical correspondence analysis method (NCCA) to approximate the unimodal response of species to an environmental gradient. The method first determines the most appropriate nonlinear explanatory factor through two screenings and then fits the chi-square transformation values of the response variables using the linear regression method and an improved heuristic optimal quadratic approximation method. The NCCA method effectively reflects the nonlinear relationship between species and environmental factors and visualizes their effects on species distribution using a biplot. Results from applying this method to a real dataset show that it outperforms the polynomial canonical correspondence analysis method proposed by Makarenkov in explaining the variance of response variables.

Summary: The study showed that the number of publications in the field of phytoremediation is increasing, with China, the USA, and India being the most productive countries. The Chinese Academy of Sciences, Zhejiang University, and the University of Florida are the top three most productive institutions in this field. The most widely used journals were the International Journal of Phytoremediation, Environmental Science and Pollution Research, and Chemosphere.

Summary: This paper investigates the effects of environmental stochasticity and toxin-producing phytoplankton on aquatic ecosystems, showing that the system has a unique and global positive solution with positive initial values. The numerical analysis demonstrates that white noise can directly impact the survival of plankton populations.

Summary: A review conducted in Serbia evaluated the presence of potentially toxic elements (PTEs) in fish in water ecosystems. The study identified and evaluated 40 relevant studies, covering 28 ecosystems and 108 locations. The most studied river ecosystems were the Danube and the Sava, and the Meduvrsje reservoir was the most studied standing water ecosystem. Several fish species were examined, with catfish, pikeperch, bream, carp, and barbel being the most studied. The findings showed elevated concentrations of PTEs in various fish species from the Danube, Sava, and Velika Morava basin rivers, with mercury being the most commonly detected element exceeding the maximum permitted concentrations (MPCs) in muscle tissue.

Summary: Improper disposal of metal-containing wastes harms the environment and human health. This study investigates the sorption and desorption of Cr6+, Cu2+, and Mn2+ by modifying polyacrylamide/methylcellulose hydrogels with bentonite or hydrotalcite. The nanocomposite produced by calcining hydrotalcite at 550 degrees C exhibits the best retention properties.

Summary: This study evaluates the pollution levels, distributions, ecological, and human health risks of potentially toxic trace elements (PTEs) in soils near uranium (U) mines worldwide. The results indicate that the studied soils are heavily polluted by U and Cd, with higher pollution levels observed in France, Portugal, and Bulgaria. Cd and U contribute more to the potential ecological risk, and oral ingestion is the main exposure route for soil PTEs. The hazard index (HI) values for children exceed the safe level for U and As, while Cu presents unacceptable carcinogenic risks. This study emphasizes the urgent need to address PTE pollution in U mine-associated soils on a global scale.

Summary: Monitoring functional diversity is crucial in addressing climate change and biodiversity loss. This study demonstrates the use of diffusion maps to reconstruct species traits directly from monitoring data and estimate functional diversity. The wider application of this method to existing data could greatly advance the analysis of changes in functional biodiversity.

Summary: The scientometric analysis based on the Scopus database revealed a significant increase in research activities on potentially toxic elements in groundwater since 2000. While arsenic and lead are the most studied PTEs, research on other elements is also showing a continuous upward trend. The USA and China are the two principal countries making the most significant contributions in terms of research output, institutions, and funding sponsors.

Summary: Nowadays, many sites are considered waste due to high potentially toxic metal (PTM) concentration. A greenhouse experiment was conducted to study the response of Brassica juncea to elevated Zn and Cu concentration in soil. The highest accumulation of Zn and Cu was found in the stem and leaf material. With increasing PTM concentration, a decline in root, biomass, and chlorophyll levels was observed. The study reaffirmed the capabilities of B. juncea to bioaccumulate Zn and Cu and provided further understanding of the translocation of these metals within plant tissues.

Summary: This study investigated the accumulation of potentially toxic metals in soils and five Alyssum species in metalliferous and non-metalliferous areas in the North Caucasus region. Results showed significant differences in accumulating ability among species, highlighting the importance of considering selection of metal hyperaccumulator species at the population level. Additionally, genetic analysis indicated considerable differences between hyperaccumulating and non-hyperaccumulating populations of Alyssum murale.

Summary: Gold mining activities are the main source of heavy metal emissions into the environment. Previous studies have focused on the impact of individual mining sites, limiting our understanding of the combined influence of global gold mining on soil contamination. This study collected research papers from 24 countries and developed a comprehensive dataset on 10 potentially toxic trace elements in soils near gold deposits, revealing widespread contamination and ecological risks.
