“…Several common daily activities at airports can contaminate water reserves, reduce water quality in regions close to airports, and have toxic effects on marine life. Substances such as aircraft fuel, ethylene glycol, and ammonia used in airports, even in extremely small quantities, are carcinogenic and can be lethal to fauna and flora, consequently causing ecosystem disturbances [18]. The use of de-icing and anti-icing: The application of these fluids without adequate discharge control results in them being washed into the rainwater drainage system, which in turn can result in a reduction in water quality and a decrease in the amount of dissolved oxygen, making it impossible for some marine living beings to survive and present potential risks to human health [19].…”

The background of this research is the environmental sustainability assessments in the aviation ecosystem, particularly concerning airports, are getting significant attention from the industry, regulators, and researchers. A standardized and comprehensive approach is essential for uniformly addressing the global impacts of these assessments across the industry. The main objective of this study is to develop a unique framework that encompasses the requirements of aviation regulators as well as industry and academic metrics, aiming for a standardized approach to environmental sustainability assessments at airports. The methodology used the Sum of Ranking Method to evaluate each environmental indicator precisely. It was applied to five airports globally, providing a diverse testing ground to assess the proposed metrics’ applicability and effectiveness and validate the framework. The results showed that applying the framework across these varied airport environments demonstrated its viability and effectiveness, indicating that it can be successfully applied to different airport realities. The conclusion shows that the developed framework can be successfully applied globally, suggesting that it can be a valid method for international adoption in environmental airport sustainability analysis, offering a standardized approach that could be accepted and utilized worldwide.

“…However, their use is limited due to concerns about toxicity to nearby aquatic systems. Agro‐based deicers can reduce dissolved oxygen (DO) due to their high organic content, especially phosphate and nitrate (Shi et al, 2018). Phosphorus from the deicers usually enters the environment at a concentration of 14–26 mg/L and causes the growth of algae, thus reducing DO for other aquatic organisms (Fischel, 2001).…”

During winter, snow and ice on roads in regions with cold weather can increase traffic crashes and casualties, resulting in travel delays and financial burdens to society. Anti‐icing or deicing the roads can serve a cost‐effective method to significantly reduce such risks. Although traditionally the main priorities of winter road maintenance (WRM) have been level of service, cost‐effectiveness, and corrosion reduction, it is increasingly clear that understanding the environmental impacts of deicers is vital. One of the most important problems in this regard is environmental contamination caused by cumulative use of deicers, which has many detrimental effects on the aquatic systems. Among the deicers, the chloride‐based ones raise the most toxicological concerns because they are highly soluble, can migrate quickly in the environment and have cumulative effects over time. In this review, we summarize and organize existing data, including the latest findings about the adverse effects of deicers on surface water and groundwater, aquatic species, and human health, and identify future research priorities. In addition, the data provided can be used to develop a framework for quantifying some of the variables that stakeholders and agencies use when preparing guidelines and standards for WRM programs. Practitioner points Pollution from the increasing use of roadway deicers may have detrimental effects on the environment. Of particular concern are the acute and cumulative risks that chloride salts pose to aquatic species. Chloride salts are water‐soluble, very difficult to remove, highly mobile, and non‐degradable. Deicers cause water stratification, change the chemicophysical properties of water, and affect aquatic species and human health. Current guidelines may not be appropriate for environmental protection and need to be revised.
