“…This behaviour has its origin mainly in the traffic emissions, solar radiation levels and human behaviour patterns. These cycles are similar to find in other urban and suburban areas (Minoura, 1999;Mazzeo et al, 2005). In the night time the concentrations remain with similar levels or with a slight increase trend with NO concentrations are always lower than NO 2 .…”

“…They included assessments of the state of health of the specimens under investigation only in strictly defined locations, e.g. near motorways, main thoroughfares in cities or in urban open spaces (Mazzeo et al 2005). However, there have been few studies on the vegetation and its state of health in urbanised areas -both in green areas and built-up areas.…”

Parks in urbanised areas fulfil an important function as they create a positive climate in cities and contribute to the good health of their inhabitants. The study gives an answer to the question of which of the species under investigation is the most suitable for planting in urbanised areas. The aim of the research conducted from 2013 to 2014 at selected sites in Poznan (Poland) was to determine the state of health of Tilia cordata Mill., Acer platanoides L. and Quercus robur L. trees and to compare their state of health depending on the location of the research sites. The aim of the research was also to determine the environmental variables that may have an influence on the state of health of the tree species under analysis. The research included statistical analyses and models based on discriminant analysis. The research revealed that the state of health of the tree species under investigation growing in the city is determined by anthropogenic factors. The closeness of the city centre, main thoroughfares and estates heated with fossil fuels are the factors that have the most negative influence on the state of health of oak, maple and lime trees. Acer platanoides L. was the species in the best state of health in parks, whereas in forests it was Tilia cordata Mill.Ke y wor d s: Norway maple, pedunculate oak, small-leaved lime, statistical models, urbanised areas

“…도시에서 O 3 과 NO 2 농도를 관측한 연구에 따르면 중심 지역, 외곽 지역, 도심 공원, 주요 도로 등 관측 지 점에 따라 다른 특성이 나타난다 (Mazzeo et al, 2005;Clapp and Jenkin, 2001;Lal et al, 2000). 도시 중심 지 역은 외곽 지역보다 NO 2 농도가 높고 O 3 농도가 낮은 데 이는 NO x (NO + NO 2 )가 자동차에서 배출되는 동시 에 이 중 NO가 O 3 을 분해하기 때문이다 (Nguyen and Kim, 2006;Clapp and Jenkin, 2001).…”

The diurnal variations of O 3 and NO 2 in an urban park and the effects of air temperature and wind speed on the diurnal variations are investigated. O 3 and NO 2 concentrations were observed at a site in an urban park of Seoul from 27 July 2015 to 9 August 2015. The O 3 and NO 2 concentrations observed in the urban park are compared to those observed at the Gangnam air quality monitoring station (AQMS). The O 3 concentration is higher in the urban park than at the Gangnam AQMS in the daytime because the amount of O 3 dissociated by NO is smaller as well as partly because the amount of O 3 produced in the oxidation process of biogenic volatile organic compounds (VOCs) is larger in the urban park than at the Gangnam AQMS. The NO 2 concentration is lower in the urban park than at the Gangnam AQMS during day and night because the observation site in the urban park is relatively far from roads where NO x is freshly emitted from vehicles. The difference in NO 2 concentration is larger in the daytime than in the nighttime. To examine the effects of air temperature and wind speed on the diurnal variations of O 3 and NO 2 , the observed O 3 and NO 2 concentrations are classified into high or low air temperature and high or low wind speed days. The high O 3 and NO 2 concentrations in the daytime appear for the high air temperature and low wind speed days. This is because the daytime photochemical processes are favorable when the air temperature is high and the wind speed is low. The scatter plots of the daytime maximum O 3 and minimum NO 2 concentrations versus the daytime averages of air temperature and wind speed show that the daytime maximum O 3 and minimum NO 2 concentrations tend to increase as the air temperature increases or the wind speed decreases. The daytime maximum O 3 concentration is more sensitive to the changes in air temperature and wind speed in the urban park than at the Gangnam AQMS.
