“…Another reason is that it supports the city's aeration. This agrees with a recent study [68], in which black carbon was measured along bicycle routes in Wrocław, Poland. The study's authors found that black carbon levels near to the river were noticeably lower than the levels near other routes in their study area.…”

Cultural tourism helps preserve cultural heritage and provides economic opportunities for local communities. A walkable cultural tourism route has been developed for the old town of Ratchaburi, Thailand. Here, we assessed changes in PM1 after cars were banned from the walkable tourist route. A near-roadway dispersion model, R-LINE, was evaluated and used to explore the base case (BC) and two scenarios, S1 and S2. In the BC, road traffic activities reflected the current situation; in S1, all vehicles were banned from the walkable route; and in S2, all drivers were encouraged to park their vehicles outside the study area. The road traffic activities in the study area were observed and used to calculate the PM1 emission rates for the model inputs. The model was capable of simulating PM1 concentration, especially the average PM1 concentration over the monitoring period. An increase in PM1 concentration was seen at the main road in S1 due to the increased traffic volume that had been redirected from the walkable route, with an increase in daily PM1 of 4.5% compared to BC. S2 showed a decrease in the PM1 concentration of 8.9%. These findings suggest the need for traffic mitigation measures prior to initiating a walkable route for cultural tourism, to meet environmental sustainability requirements.

“…Natural elements or urban landscapes play great role in protecting landscapes from climate change [1] by building urban resilience [2,3] and reducing the carbon footprint [4], as well as significantly impacting the health and well-being of the citizens [5][6][7]. The presence of green areas, such as urban parks, is often considered in the context of quantity (area per capita) in planning documents.…”

Providing restorative green areas is important, especially in the city, where the level of stress and noise is relatively high. Therefore, green areas, such as urban parks, should provide coherent audio–visual stimuli to achieve positive perception by the residents. Therefore, this study aims to investigate the potential for psychological regeneration in urban parks in terms of visual and soundscape assessment as well as to assess the role of the intensity of different types of sound contributing to the positive perception of the soundscape. In order to achieve this aim, we chose eight urban parks in the city of Wrocław to provide audio and visual stimuli and used a group of young adults as survey respondents. The results show that visual stimuli are perceived as undoubtedly more important than the soundscape, and that talking, footsteps, music, children (playing), birds, and vehicles are the most significant types of sound that contribute to the perception of soundscape depending on the level of intensity of the sound (with children and vehicles being beneficial if they are completely inaudible). We conclude that the quality of the soundscape is essential to improve the restorative potential of urban parks and, in consequence, to improve the well-being and health of the city dwellers, and there is a necessity for strategies and development plans including sensually coherent and inclusive public parks in the city of Wrocław.

This study investigates the concentrations and spatial distribution of toxic heavy metals (Cd, Cu, Pb and Zn) through chemical analysis of rainwater samples, characterized by different land use, emission sources, tra c conditions and population density. The average concentrations at the ve sites were 52.9, 11.8, 14.6 and 0.93 µg l − 1 for Zn, Pb, Cu and Cd, respectively. The concentrations for all heavy metals were signi cantly higher (p < 0.05) at the central and south Tehran areas compared to the west and north, due to different urban characteristics, higher pollution emission rates from tra c and domestic sectors, and local winds patterns developed within the city. High tra c load in the central part of Tehran also escalates the heavy metal concentrations in this region. The signi cant correlations between the studied heavy metals at the ve sites indicate common, local anthropogenic sources. The heavy metal concentrations were higher in spring than in winter, likely associated with dilution processes in winter and the restriction measures due to COVID-19 pandemic. During the lockdown period, a drastic decrease in tra c load was observed in Tehran, con rming that motor vehicles is the main regulatory factor for air pollution and potential toxic elements in the city. be high, indicating common origin from local anthropogenic sources, mainly from the tra c and industrial sectors.Analysis of heavy metals not only in street (road) and airborne dust samples, but also in rainwater (wet deposition) is very important for identi cation of their sources, distribution, solubility and bio-availability characteristics, which determine ecological and human health risks. Current results provided essential preliminary knowledge of rainwater chemistry in Tehran, helping in establishing regulation and mitigation strategies for better control of air pollution and toxic heavy metals. More systematic analysis of wet deposition in Tehran, Iran and in the Middle East is needed for better assessment of rain chemistry, as a way to investigate atmospheric composition.
