“…In this respect, many Romanian tourist areas are affected by the past (Levei et al, 2009;Filip & Cocean, 2012) or current pollution (Nuta et al, 2015). Among the present environmental issues, Romania is affected by air pollution (gas, material particles, noise), caused mainly by road traffic (Bucharest, Constanța) (Iordache et al, 2013;Oncioiu et al, 2020); soil pollution by heavy metals and waste, especially domestic (Ungureanu et al, 2018) which damage water bodies and landscape (Romcea et al, 2018;Breban, 2019). It is also well known that the reduction of forested areas by illegal logging (Petrișor, 2015;Dumitrașcu et al, 2020) facilitates the spread of invasive plants (Doroftei & Anastasiu, 2014;Matei, 2018).…”
