Summary: The impact of population expansion through economic growth and development has been identified as one of the key drivers of both water and sediment contamination from potentially harmful elements (PHEs). This study measured the concentrations of PHEs in water, sediment, and fish in four zones within Winam Gulf and Lake Victoria area of Kenya. The results show that the concentrations of PHEs in water and sediment exceeded the guideline levels, while the contributions of PHEs to the recommended daily intakes were below threshold guidelines for both aquaculture and wild fish.

Summary: The study evaluated the pollution degree of toxic trace elements (TTEs) in soils of a typical gold mining area, showing that arsenic (As) and mercury (Hg) posed the highest pollution risk, especially with extremely high ecological and health risks. While other toxic elements had hazard index values below safe levels, arsenic presented unacceptable carcinogenic risks for local residents, calling for more efficient policies to control contamination in the soils.

Summary: The study compared the concentration of PTEs in five fish species from the Caspian Sea and calculated the non-carcinogenic risk for both children and adults. The results showed that the PTEs in the investigated fish species posed a potential non-carcinogenic risk for both children and adults, with the highest TTHQ value found in carps.

Summary: The study found that the concentration of PHEs in fillet trout varies by country, but the non-carcinogenic risk for adult consumers is acceptable in most countries, while children in Turkey face unacceptable non-carcinogenic risk.

Summary: This study investigated the soil pollution status, levels of exposure, and potential ecological and health risks in the Angouran mining area in Iran. The study found that the highest concentrations of potentially harmful elements (PHEs) were present in the soils near waste rock dumps. Assessment methods including blood analysis and in vitro digestion extractions were used to evaluate the potential health impacts of exposure to PHEs. The study highlights the importance of using a combination of techniques to assess pollution and health risks in mining areas.

Summary: The study found that small-scale fishing households around Lake Victoria in Kenya are consuming less fish, perceiving higher fish prices, and are more inclined to sell fish rather than consume it due to the COVID-19 pandemic. Many fishers and traders are spending less time fishing and trading, with high concerns about being infected with COVID-19. Movement restrictions, COVID-19 concern, and high lake levels in the region are likely to limit fishing activities and fish access.

Summary: The cerrado biome in Brazil is strategically important for agriculture, energy production, and other activities. However, the intensive use of chemicals and other products has led to potentially toxic elements contaminating the soil. This study evaluates the presence of these elements in the Ariranha stream basin and finds contamination levels exceeding regulatory limits.

Summary: In this study, the concentration of sixteen odour active substances in ten black acrylic paint samples was measured using GC-GC-MS. The analysis of the most abundant odour active volatiles indicated that some samples had repelling or unpleasant odours, mainly characterized by aromatic, solvent-like, mothball-like or geranium-like smells. Other samples had fruity/fermented, fruity/apple juice-like, mushroom-like or cocoa-like/earthy odours. The results showed that all paints contain different and specific patterns of odour active substances and volatiles, with potential health effects when these substances are combined.

Summary: This study used a systematic literature review to identify sources of potentially toxic elements (PTEs) in the aquatic environment. The analysis revealed both natural and anthropogenic sources, such as mining, agriculture, industries, and domestic effluents. The study also highlighted specific locations where environmental remediation studies should be conducted to prevent and address PTE pollution.

Summary: This study investigated the urinary elemental concentrations of 357 adults from Western Kenya, revealing high rates of excess intake for certain micronutrients and low rates of deficiency. Despite overall similar ranges of elemental concentrations, there were exceptions in counties bordering Lake Victoria where food consumption habits differed. Corrections for urinary dilution using creatinine, specific gravity, and osmolality led to a general reduction in reference values for specific elements.

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.

Summary: The aim of this study was to assess the health risk of mercury-contaminated fish consumption for urban and non-urban populations in Roraima state, Amazon, Brazil. The results showed that regardless of fish consumption level, residency type, or population subset, anyone consuming fish from the sampled locations is at high risk of mercury ingestion, except for adult men consuming an average of 50 g of fish per day.

Summary: Gypsum mining spoil (GS) has been found to be a promising soil amendment for reducing the availability of Potentially Harmful Elements (PHEs) and promoting plant growth. Its use not only helps remediate polluted soils but also allows for sustainable management of this waste material and reduces its social and environmental impact.

Summary: The study revealed that elements such as arsenic and titanium exceeded the world soil average in soils near an abandoned gold mine in Ghana, indicating high soil contamination levels. Adults and children faced significant human health risks from consuming soil, especially children and women. Some native plants like Chromolaena odorata and ferns may have the potential to reduce soil contamination and associated human health risks by accumulating elements like arsenic, copper, titanium, and zinc into their shoots.

Summary: Pollution of aquatic ecosystems is a major challenge worldwide, with heavy metal pollutants posing a threat to aquatic organisms and human consumers. This study assessed the concentrations of selected heavy metals in Limnothrissa miodon fish from Lake Kariba, Zambia. The results showed that the concentrations of heavy metals were within safe limits for human consumption, but varied significantly across fishing zones. The health risks to consumers were found to be minimal. Further studies are needed to understand the sources of heavy metals and monitor potential elevation of concentration levels.

Summary: This study characterizes lignite samples from Kapurdi, Giral, and Sonari mines in Rajasthan's Barmer Basin using petrographic and geochemical techniques. The results provide insights into the geochemical properties, hydrocarbon potential, depositional environment, and paleo-climatic conditions of these lignite deposits. The study finds high volatile matter and sulfur concentrations in the Barmer lignite deposits, as well as indications of a wet environment during organic material decomposition. The findings have implications for understanding the coalification profile and hydrocarbon source rock potential in the region.

Summary: The assessment of heavy metal concentrations in agricultural soil is important for crop safety and quality, as well as potential risks to human health. This review analyzed published data on seven heavy metals in Iranian farmland soils and found that nickel and cadmium exceeded permissible levels. Arsenic showed significant contamination in multiple provinces, while lead and cadmium were highly contaminated in Fars province. Overall, the contamination levels of heavy metals in Iranian agricultural soils were relatively low.

Summary: This study analyzed apatite grains from the Angico dos Dias Carbonatite Complex region in Brazil using an electron probe microanalyzer. The results showed that the apatite grains had characteristics of metacarbonatitic lithotypes and some had undergone substitution processes. Statistical analysis helped identify the sources of the apatite grains and confirmed the presence of carbonatitic bodies in the area.
