    Opis:
    The goal of the paper was to define the phytoindication ability of selected plant species in the conditions of the impact of traffic on the environment. The contents of the following trace metals were analysed: Cd, Cr, Cu, Ni, Pb, Zn in three plant species: moss Pleurozium schreberi (Brid.) Mitt., dandelion Taraxacum officianale F. H. Wigg. and in Norway spruce Picea abies (L.) H. Karst alongside the communication route Kraków-Zakopane. The plant samples (green parts of moss, leaves of dandelion, and two year old needles of common spruce) were taken in seven transects perpendicular to the road in the following distances from the edge of the road: 5 m, 10 m, 50 m and 100 m. The moss Pleurozium schreberi turned out to be the best indicator among the tested plant species because it accumulated trace metals in the highest concentrations. In the leaves of the dandelion lower concentrations of metals were found, while the lowest ones were in the needles of the spruce.
    Celem pracy była ocena zdolności indykacyjnych wybranych roślin wskaźnikowych znajdujących się pod wpływem drogowych zanieczyszczeń komunikacyjnych. Oznaczono zawartości następujących metali śladowych: Cd, Cr, Cu, Ni, Pb, Zn w trzech gatunkach roślin: mchu rokietniku pospolitym Pleurozium schreberi, mniszku pospolitym Taraxacum officianale i w świerku pospolitym Picea abies pobranych wzdłuż drogi Kraków – Zakopane. Próbki roślin (zielone części mchu, liście mniszka pospolitego oraz dwuletnie igły świerka pospolitego) pobrane zostały w obrębie transeptów rozmieszczonych prostopadle do drogi w odległości 5, 10, 50 i 100 m od jej krawędzi. Rokietnik pospolity Pleurozium schreberi okazał się najlepszym indykatorem, bowiem kumulował największe ilości badanych metali. Niższe koncentracje metali stwierdzono w liściach mniszka pospolitego, a najmniejsze w igłach świerka.

    Opis:
    The trees of parks and gardens support many species, the survival of urban-dwelling species mainly bird species. Birds amongst other species provide a wide range of environmental and social functions to cities and urban dwellers. The present study aims to know bird diversity in two parks as bioindicator of automobile air pollution exposure, landscape changes and/or human interactions. The study areas were selected as per heavily-populated neighborhoods, nearby office buildings, nearby roads and continuous vehicular movements, human interactions as visitors, where high levels of human disturbance are common. The study was carried out at 2 sampling stations viz (i) Elliot park and (ii) Agri-horticulture Society. The bird species diversity was studied by qualitative and quantitative assessment. Indices were Species richness, Index of Dominance, Relative abundance, Shannon-Wiener Diversity Index and Evenness Index for birds for all selected sites were calculated using the statistical formulae. The present results as bioindicators bird species clearly indicate that the bird species are very few in numbers in both the parks. When comparison made between both the parks, it was observed less number of bird varieties (16 types) in Elliot park than varieties (9 types) more less in number in Agri-horticulture society. This study is a preliminary assessment of bird diversity but further researches are needed in relation to biochemical and genetic damage study as well as air pollution load by using instruments. In the present study it was concluded that the less numbers of birds and their different diversity indices were found a decreasing trends, though there no attempt has been made on physico-chemical properties of present air pollutants. The less number of varieties of bird species are as tolerant bioindicators, which may be due to the vehicular pollution and/or human interference and/or landscape changes due to nearby neighborhood blocks, office and residential buildings, continuous movement of vehicles etc.

    Opis:
    The present study deals to know morphological damages of leaves of four selected plant species near roadside due to vehicular air pollution in Kolkata, India. The selected plant species are Ficus bengalensis, Ficus religiosa, Alstonia scholaris and Neolamarckia cadamba as these are very common as avenue trees. The study area was selected as per Low vehicular load (LVL) as control area, moderate vehicular load (MVL) area, high vehicular load (HVL) area and heavy vehicular load (HeVL) These three sampling stations were selected on the basis of moderate, high and heavy traffic density and continuous vehicular movement as per visualization. The control area was considered as time dependent vehicular movement due to less traffic density. The morphological damages with special reference to length (L), breadth (B) and L/B ratio and visible injuries in leaves. The visible injuries such as pigmentation, chlorosis, necrosis and burning of leaves of four selected species is documented. There was an increasing and decreasing tends in all four plant species at all three vehicular emission exposed sites (MVL, HVL and HeVL) compared to control site (LVL). In all experimental sites such as MVL, HVL and HeVL, the extra growth and reduction pattern significantly (P < 0.001, 0.01 or 0.05) observed when compared to control site (LVL) for L, B and L/B ratio. The visible injuries (in %) of leaves were also observed in increasing trends. This study is a preliminary assessment of tolerant species that already have been used in greenbelt development to protect air pollutants as well as biological monitoring to know exact load of automobile air pollution but further researches are needed in relation to biochemical and genetic damage study. It was observed that out of four selected species Ficus bengalensis, Alstonia scholaris and Neolamarckia cadamba are more tolerant species and Ficus religiosa is a less tolerant species because of these may have fighting abilities by waxy coatings, accumulation and degradation abilities to vehicular air pollution at all exposed area when compared to control area.
