“…This continuous monitoring is essential to track changes over time, to evaluate the effectiveness of mitigation measures implemented, and to provide early warning in case of resurgence of PTEs concentrations. In particular, continuous monitoring of PTEs should be considered to reduce exposure to PTEs [118].…”

This study presents an analysis of soil contamination caused by Ni, Zn, Cd, Cu, and Pb at municipal solid waste (MSW) landfills, with a focus on ecological risk assessment. The approach aims to assess how different landfill practices and environmental conditions affect soil contamination with potentially toxic elements (PTEs) and associated environmental risks. Soil samples were collected from MSW landfills in Poland and the Czech Republic. The research included a comprehensive assessment of PTEs in soils in the context of global environmental regulations. The degree of soil contamination by PTEs was assessed using indices: Geoaccumulation Index (Igeo), Single Pollution Index (Pi), Nemerow Pollution Index (PN), and Load Capacity of a Pollutant (PLI). The ecological risk was determined using the Risk of PTEs (ERi) and Sum of Individual Potential Risk Factors (ERI). The maximum values of the indicators observed for the Radiowo landfill were as follows: Igeo = 4.04 for Cd, Pi = 24.80 for Cd, PN = 18.22 for Cd, PLI = 2.66, ERi = 744 for Cd, ERI = 771.80. The maximum values of the indicators observed for the Zdounky landfill were as follows: Igeo = 1.04 for Cu, Pi = 3.10 for Cu, PN = 2.52 for Cu, PLI = 0.27, ERi = 25 for Cd, ERI = 41.86. The soils of the tested landfills were considered to be non-saline, with electrical conductivity (EC) values less than 2,000 μS/cm. Varying levels of PTEs were observed, and geostatistical analysis highlighted hotspots indicating pollution sources. Elevated concentrations of Cd in the soil indicated potential ecological risks. Concentrations of Cu and lead Pb were well below the thresholds set by the environmental legislation in several countries. In addition, Ni concentrations in the soils of both landfills indicated that the average levels were within acceptable limits. Principal Component Analysis (PCA) revealed common sources of PTEs. The identification of specific risk points at the Radiowo and Zdounky sites contributes to a better understanding of potential hazards in landfill environments. By establishing buffer zones and implementing regular maintenance programs, emerging environmental problems can be addressed in a timely manner.

“…Industrialization, globalization, and economic development influence the quality of the environment and have a negative impact on society [34], and the quality of life [35]. In addition, inefficient municipal management [1] waste management, and recycling, specifically in developing countries [36], have generated concerns in the face of environmental pollution, and this brings a sense of guilt from sustainability-conscious people because they feel that they are not doing enough to reduce the negative impact on the environment [37]. Therefore, it is important to assess and mitigate the obstacles that people face in recycling, such as a shortage of recycling facilities, a lack of time, or inconvenience in managing garbage [38].…”

The purpose of the study was to identify the sociodemographic factors that influence the feeling of guilt about recycling household waste in Peruvian families living in Sullana. The rapid generation of waste in urban and rural areas leads to the development of multidisciplinary research to mitigate environmental pollution, which not only affects tourism but also the quality of life of the population. The study design was non-experimental, descriptive, causal, and explanatory. The research approach was quantitative. The instrument was validated (Cronbach's alpha = 0.932), and it was observed that age, employment status, educational level, income, and professional career were significantly related (p<0.05) to the feeling of guilt for recycling. There is a high level of guilt about recycling household waste related to an attitude of success and social norms, and a mild level related to an attitude of failure. The sociodemographic profile of Peruvian families living in Sullana is characterized by an average age of 35 years, employment, secondary, technical, and higher education, as well as income between S/500 and 1500 soles and living in a family nucleus composed of 3-5 people. These findings are important for the elaboration of public policies in the environmental management of solid waste and in the academic sphere to raise awareness among the different actors to mitigate climate change and contribute to the sustainability of natural resources. It is recommended to apply compensatory incentives to families to achieve positive changes in household waste management.
