COVID-19 was not taken seriously by many of us until the wave hit our countries and impacted daily life routines and travel plans, similar to our responses to climate change. COVID-19 led to a decrease of anthropogenic activities in Turkey, largely due to lockdown. Changes in the air quality index (AQI) were assessed before and during coronavirus. In this study, the authors investigated the changes of AQI for 2.5 µm particulate matter (PM 2.5), a primary air pollutant, as well as ozone, a secondary air pollutant, in Turkey during December 2019, April 2020, and May 2020. Overall, the PM 2.5 index improved by 34.5% by the end of April 2020. However, the ozone index increased from 16.8 to 28.8 by the end of April. The increase in ozone is attributed to the reduction of PM levels, which increased sunlight penetration. Before COVID-19, the AQI for Turkey was categorized as unhealthy for sensitive groups (PM 2.5 = 103); however, during the pandemic, AQI fell to lower boundaries of the moderate category by May 2020 (PM 2.5 = 56.9). Changes in municipal wastewater were also assessed. Municipal wastewater quality and hospital waste generation did not change during the pandemic in Turkey. Therefore, we should not expect COVID-19 risks in treatment plant effluents. This study gives confidence to regulators that when strict measures are implemented, air quality can improve.

“…Given the importance of various parameters in decision-making, the vector of parameters’ weight (the coefficient of parameters’ significance) is drawn based on the dual comparison (Saaty, 1980) in Expert Choice software to find the weight of each parameter. These comparisons are made in a square matrix n × n, where the number of rows and columns is equal to the number of criteria compared (Mohebbi Tafreshi et al, 2014; Osra and Kajjumba, 2019):…”

The present study evaluated and selected the best location among susceptible landfill sites in Rudbar County using 27 criteria, as the maximum effective criteria, in the decision-making process. The emergence and comparison between the two methods of fuzzy and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) with an engineering–geological approach have been conducted to obtain the best results. In this regard, inappropriate regions for landfill construction have been restricted after the conflation of two maps based on the restriction criteria. Then, the direction of prevailing winds and proper area for landfill construction was investigated for a 20-year perspective, and the regions that had more than 35-hectare area and were not located in the direction of the prevailing winds have been identified as responsive sites for landfill construction. Ultimately, selected susceptible regions were prioritized separately based on the TOPSIS and fuzzy methods. To ascertain the accuracy of the results and the reality of the resulted models, complementary field studies, geotechnical digging, and engineering–geological experiments have been used as verification parameters. According to the results of the verification, the fuzzy model having maximum matches with the verified data has been suggested for prioritizing susceptible regions.

Despite environmental regulations in Ecuador, particularly in the Province of Azuay, the solid waste final disposal management is still a socio-environmental problem, worsened by weak governance processes. The province has three sanitary landfills with almost expired service lives. The site selection was based on circumstantial reasons, which makes landfills more likely to cause environmental pollution and, therefore, have negative implications for public health. The largest landfill serves Cuenca and also leases service to other small cities. The remaining two are small and, accordingly, have limited technology and fewer resources. In this context, the main aim of this study is to evaluate the terrain of the province to find the most suitable area for landfill siting. A multi-criteria decision analysis, integrated with a geographical information system and analytical hierarchy process methodology, was conducted. Fourteen factors and seven constraints were simultaneously analysed, divided into technical, environmental, social, and economic categories; 15 of these criteria were from the Ecuadorian Unified Text of the Secondary Legislation of the Environmental Ministry. According to the results, 76.17% of the territory is not suitable for landfill implementation, and the unrestricted area represents the remaining 23.83%. The highest landfill suitability index (70–81%) is located in the south of the province in Santa Isabel, Oña, and Nabón cantons, which are dry and clay-rich areas.
