Nitrogen dioxide (NO2) at a high concentration is among the most common and harmful air pollutants. The present study aimed to explore the physiological responses of plants exposed to NO2. A total of 41 plants were classified into 13 functional groups according to the Angiosperm Phylogeny Group classification system. The plants were exposed to 6 μL/L NO2 in an open-top glass chamber. The physiological parameters (chlorophyll (Chl) content, peroxidase (POD) activity, and soluble protein and malondialdehyde (MDA) concentrations) and leaf mineral ion contents (nitrogen (N+), phosphorus (P+), potassium (K+), calcium (Ca2+), magnesium (Mg2+), manganese (Mn2+), and zinc (Zn2+)) of 41 garden plants were measured. After NO2 exposure, the plants were subsequently transferred to a natural environment for a 30-d recovery to determine whether they could recover naturally and resume normal growth. The results showed that NO2 polluted the plants and that NO2 exposure affected leaf Chl contents in most functional groups. Increases in both POD activity and soluble protein and MDA concentrations as well as changes in mineral ion concentrations could act as signals for inducing defense responses. Furthermore, antioxidant status played an important role in plant protection against NO2-induced oxidative damage. NO2 poses a pollution risk to plant systems, and antioxidant status plays an important role in plant protection against NO2-induced oxidative damage. In conditions of strong air pollution, more evergreen plants may be considered in landscape design, particularly in seasonal regions. The results of this study may provide useful data for the selection of landscaping plants in NO2 polluted areas.

Foliar uptake of gaseous NO2 mainly occurs through the stomata and disrupts normal plant growth, but no detailed reports about the physiological responses of plants exposed to NO2 are available. In this study, to study leaf physicochemical responses, stomatal characteristics and chloroplast structure, we observed the leaves of Carpinus putoensis W.C.Cheng after exposure to NO2 (6 μL/L) for five time periods (0, 1, 6, 24, and 72 h) and after 30 days of recovery following NO2 exposure. Our results showed that short-duration exposure to a high concentration of NO2 had significant negative impacts (p < 0.05) on the chlorophyll content, photosynthesis and chloroplast-related physicochemical processes of C. putoensis leaves; with the exception of one hour of NO2 exposure, which was helpful for plant physiological responses. Moreover, NO2 exposure significantly increased the thickness of the palisade/spongy tissue and caused swelling of the thylakoids within the chloroplasts; this thylakoid swelling could be reversed by removing the pollutant from the air flow. Restoration of unpolluted air alleviated the toxic effects of NO2, as indicated by an increased chlorophyll content, net photosynthesis, and PSII maximum quantum yield. These results could support the development of a treatment for roadside trees that are exposed to NO2 as a major road pollutant.

ÖZET: Kırsal nüfusun kentlere olan hızlı akımı, kentleri bu konuda hazırlıksız yakalamıştır. Artan nüfusun talebi ile baskılar yaşayan kentlerde çevre sorunlarını artmakta ve kent konforunu etkilemektedir. Artan hava kirliliği Bingöl ilinde yaşam kalitesini düşürmekte özellikle kış aylarında bu olumsuzluklar daha yoğun bir şekilde hissedilmektedir. Hava kirliği insanoğlunun konforu üzerine olumsuz etkilere neden olmaktadır. İnsan etkilerinden kaynaklanan hava kirliğinin Bingöl İli üzerindeki etkilerini amaçlayan bu çalışma 2007-2015 yılları arasında 8 yıllık uzun zamanı kapsayan uzun vadeli meteorolojik değerlerden yola çıkılarak yapılmıştır. Aynı zamanda araç ve konut sayısındaki değişimler göz önünde bulundurularak hava kalitesiyle arasındaki bağ incelenmiştir. Çalışmada metot olarak istatiksel yöntemlerle CANOCO veri tabanında ordinasyon analizleri yapılmıştır. Çıkan analiz sonuçlarına göre hava kalitesi üzerindeki değişken elamanlar olan araç sayısı, konut sayısı ve meteorolojik etmenlerin zamansal değişimleri incelenerek geleceğe dair senaryolar üretilmiş ve Bingöl İli için alternatif çözüm önerileri belirtilmiştir. Aynı zamanda çıkan sonuçlara göre Bingöl kent merkezi hava kalitesi yönünden çoğu zaman Uluslar Arası Hava Kalitesinin belirlemiş olduğu sınır değerlerini aşmamıştır.Anahtar kelimeler: Bingöl, canoco, hava kalitesi, ordinasyon, ABSTRACT: Rapids immigration of rural population to urban population causes nonpreparition of city's population growth. Due to growing population demand, in these cities environmental problems increase and city comfort is influenced. Increasing air pollution causes a downfall in life quality. Especially, in winter season these problems are seen clearly.Air pollution causes negative effects on people's comfort.This study aiming to find effects of air pollution on Bingol city which is caused by people's effets.It was made between 2007-2015 years.This octennical study was proceeded with long term meterological values, also considering the number of changes in vehicle and housing the tie between air quality was investigated.As a work description ,with statistical methods ordination analysis were made in CANOCO database.According to the analysis result, numbers of vehicle and housing which are changeable factors on air quality and timewise alteration of meterological factors were investigated. Therefore, prospectively scenarios were made and solution offers were stated. At the same time, according to study result of Bingol city center;air quality does not exceed the limit values of International Air Quality.
