In the present study species like Mangifera indica, Linn., Cassia fistula, Linn., and Eucalyptus hybrid were exposed to different air pollution load for short duration (active biomonitoring). Variation in biochemical parameters like chlorophyll, protein, soluble sugar free amino acid, ascorbic acid, nitrate reductase, superoxide dismutase and peroxidase in the leaves were found to be pollution load dependent. These variations can be used as indicators of air pollution for early diagnosis of stress or as a marker for physiological damage to trees prior to the onset of visible injury symptoms. Just by analyzing these biochemical indicators air quality can also be assessed.

Protein content in plants exhibits both an increasing and decreasing trend in response to pollution stress depending on the plant species and its inherent resistance against pollution. "

    ABSTRACT: Present study was performed in urban forests of Aizawl, Mizoram, North East India falling under an Indo-Burma hot spot region of existing ecological relevance and pristine environment. Phyto-sociolology of invasive weeds has been performed and results revealed that Lantana camara was the most dominant invasive weed. Further, the air quality studies revealed high suspended particulate matter (SPM) as well as (RSPM) in ambient air of Aizawl, Mizoram, North East India. Bio- monitoring through plant leaves has been recognised as recent thrust area in the field of particulate matter (PM) science. We aimed to investigate that whether Lantana camara leaves may act as biomonitoring tool hence an attempt towards its sustainable management. The quantity of RSPM and SPM at four different sites were much higher than the prescribed limits of Central Pollution Control Board of India during summer and winter season. The dust deposition of Lantana camara leaves was found 1.01 mg/cm² and pertaining to the biochemical parameters, pH was found 7.49, Relative water content (RWC) was found 73.74 %, Total chlorophyll (TCH) was found 1.91, (Ascorbic Acid) AA was found 7.06 mg/g, sugar was found 0.16 mg/g, protein was found 0.67 mg/g, catalase was found 30.76 U/mg protein, peroxidase was found 0.16 U/mg protein and APTI was found 12.91. Lantana camara was observed in good category in Anticipated Performance Index (API) which shows the tolerant and conditioning capacity of air pollution. Therefore, present study recommended the use of Lantana camara as biomonitor which may further have sustainable management implications of an invasive plant.

Photosynthetic pigment content (Rabe and Kreeb 1980; Carreras et al.1996; Tripathi and Gautam 2007; Hassan et al. 2013), levels of total protein (Tripathi and Gautam 2007; Sing et al. 2013) and thiol groups (Ding et al. 1994), rate of lipid peroxidation (Carreras et al.1996; Rhoden et al. 2008; Hassan et al. 2013), leaf fluctuating asymmetry (Leung et al. 2000; Zakharov et al. 2000), phenological parameters (Sanz et al. 2011), and seed production (Savinov 1998) of various plant species are widely used or recommended for these purposes . However, the nonmonotonic dose–response dependences of these indexes have been insufficiently explored under different environmental pollution intensity in a wide range of values. "

    ABSTRACT: Various plant indexes are used or recommended for bioindication. However, the nonmonotonic dose-response dependences (hormesis and paradoxical effects) of these indexes are insufficiently explored upon exposure to pollution. We studied the dependences of these Betula pendula indexes on the intensity of motor traffic pollution. Regression analysis did not reveal any dependence of chlorophyll and carotenoid content on traffic intensity (in 2008 and 2010-2013). Lipid peroxidation rate had different versions of paradoxical effects in 2008 and 2010 to 2012 and increased in comparison with control under an increase in pollution level in 2013. In 2010 to 2012, all dose-response dependences for total protein and thiol group content were biphasic and multiphasic paradoxical effects. In 2013, an increase in traffic intensity induced a linear reduction in protein content and an increase in thiol group level in comparison with the control. In most cases, the studied phenological indexes and seed production decreased monotonically in comparison with the control following an increase in traffic intensity. Only in 2010 and 2013, share of fallen leaves had hormesis and paradoxical effect accordingly. Fluctuating asymmetry had a paradoxical effect and hormesis in 2008 and 2012, accordingly, and increased in comparison with the control under an increase in the level of pollution in 2010 to 2011.

    • "Once the pollutants are released into the atmosphere, only the plants are the hope, which can mop up the pollutants by adsorbing and metabolising them from the atmosphere. Therefore, the role of plants, in the air pollution abatement, have been increasingly recognised in recent years (Woo and Je 2006; Tripathi and Gautam 2006; Hoque et al. 2007; Joshi and Swami 2009; Rai 2011a, b, 2013). In urban environment, tree play an important role in improving air quality by taking up gases and particles (Horaginamani and Ravichandran 2010; Woo and Je 2006). "

    ABSTRACT: Bio monitoring studies are extremely relevant in the field of air pollution science in relation to urban ecosystem restoration. The present study was designed in order to assess the dust capturing efficiency and air pollution tolerance index (APTI) of 12 selected tree species growing along the road side at control and polluted site of Aizawl, Mizoram, northeast India. Highest dust deposition was found in Ficus benghalensis (1.02 mg cm−2) and lowest in Bauhinia variegate (0.54 mg cm−2) at polluted site. APTI of 12 plant species were evaluated by analyzing four important biochemical parameters such as ascorbic acid content, relative water content, leaf extract pH and total leaf chlorophyll. High values of APTI were recorded in F. benghalensis (19.48) and least for Artocarpus heterophyllus (8.11) at control site. The anticipated performance index (API) was calculated for different species by combining the resultant APTI values with some relevant biological and socioeconomic characters. According to API, F. bengalensis, Mangifera indica, Psidium guajava, Ficus religiosa, Artocarpus heterophyllus and Lagerstroemia speciosa were evaluated as the best suited variety for plantation along the roadside of the polluted area.
