“…When in its double-charged ionic form, Hg is highly soluble and can interact with naturally occurring organic material [ 19 , 20 ]. Other inorganic forms, such as chalcogenides, are more lithogenic and assumed to have lower bioavailability [ 21 ]. The primary environmental risk is attributed to methylmercury (MeHg), a respiration byproduct produced by sediment bacteria [ 22 ].…”

The Sea of Azov, an inland shelf sea bounding Ukraine and Russia, experiences the effects of ongoing and legacy pollution. One of the main contaminants of concern is the heavy metal mercury (Hg), which is emitted from the regional coal industry, former Hg refineries, and the historic use of mercury-containing pesticides. The aquatic biome acts both as a major sink and source in this cycle, thus meriting an examination of its environmental fate. This study collated existing Hg data for the SoA and the adjacent region to estimate current Hg influxes and cycling in the ecosystem. The mercury-specific model “Hg Environmental Ratios Multimedia Ecosystem Sources” (HERMES), originally developed for Canadian freshwater lakes, was used to estimate anthropogenic emissions to the sea and regional atmospheric Hg concentrations. The computed water and sediment concentrations (6.8 ng/L and 55.7 ng/g dw, respectively) approximate the reported literature values. The ongoing military conflict will increase environmental pollution in the region, thus further intensifying the existing (legacy) anthropogenic pressures. The results of this study provide a first insight into the environmental Hg cycle of the Sea of Azov ecosystem and underline the need for further emission control and remediation efforts to safeguard environmental quality.

Life cycle assessment (LCA) is a robust tool for evaluating the environmental impacts of products, processes, and systems throughout their entire life cycle. This article presents a comprehensive investigation into the potential of LCA in drilling methods. The growing emphasis on sustainable and environmentally responsible drilling practices is becoming a critical concern in the drilling industry. As demand for natural resources continues to rise, the need for accurate assessments of the environmental impacts associated with various drilling methods becomes increasingly essential. LCA offers a holistic perspective on all key stages of the drilling industry, providing reliable data and serving as a valuable resource for informed decision‐making aimed at promoting sustainable and optimized drilling techniques. This article delves into the challenges and complexities surrounding LCA evaluations in the context of drilling operations. It underscores the importance of LCA in enhancing the management of drilling cuttings, waste, and surplus materials generated during drilling activities, as well as the effective handling of drilling mud. Additionally, it highlights the critical issue of groundwater contamination resulting from drilling operations. By presenting a holistic view of the life cycle of drilling products and processes, the article offers practical insights into improving and optimizing drilling techniques and waste management strategies. Moreover, the article examines the challenges and potential solutions associated with implementing LCA in these areas. It aims to support responsible and informed decision‐making, ultimately leading to improved drilling performance and enhanced environmental management.
