“…Industrial pollution occurs due to numerous pollutants in the form of solid, liquids and gases. Varieties of toxic pollutants in the form of carbon monoxide (CO), volatile organic compounds (VOC), methane (CH4), oxides of nitrogen (NOx), suspended particulate matter (SPM) and heavy metals in the environment due to such oil and gas Plants (Durrani et al, 2004;Flagan & Seinfeld, 2012;Förstner & Wittmann, 2012;Bhandarkar, 2013). The presence of these pollutants causes an adverse effect on living organisms including both plant and animal that ultimately lead towards change in structure and function of an ecosystem (Bruno et al, 2003;Walker et al, 2012).…”

It was hypothesized that different plant species vary in response to the oil and gas pollution in terms of composition and distribution pattern as well. Some of the plants have more tolerance to heavy metals accumulation in polluted ecosystem than others. Quantitative ecological techniques using quadrat methods were applied in a stratified random design around the Nashpa Oil and Gas Plant District Karak to check specific plant indicators that can grow, survive and show more tolerance against Oil and Gas pollution. In four directions from Gas Plant 10 stations were established at a distance of one Km from each other. Different size of quadrats i.e. 1×1 m 2, 5×5 m 2 and 10×10 m 2 for herbs, shrubs and trees were used respectively. The phyto-sociological attributes of each species (density, relative density, frequency, relative frequency, cover, relative cover and Importance Values Index) were measured at each station. Furthermore, Calotropis procera was investigated for Pb, Cr and Cu heavy metals accumulation uisng atomic absorption spectrophotometer. All the collected data matrices were analyzed via Cluster analysis and Canonical Correspondence Analysis (CCA) using PC-ORD version 5 and CANOCO software. A total of 113 plant species were recorded belonging to 44 families from the Nashpa Oil and Gas Plant. Dominant and rare plants of heavy, moderate and less-polluted regions were identified and assessed. Result showed that Calotropis procera has more tolerant against pollution. It was concluded that the Oil & Gas Plant has significant effect on surrounding habitat plants for heavy metal accumulation. Higher concentration of K, pH and organic matter has significant effects (p≤0.002) on plant species diversity and its distribution pattern. Result of Pb and Cu accumulation in C. procera showed heavy metals accumulation increased from less polluted sites towards moderate and more polluted regions gradually. It is recommended that further study needed to examine other dominant species as well.

“…Many of these traits are related to & H. Singh hukumsingh97@yahoo.com the mitigation and adaptation potential, which are mostly affected by the air pollutants such as carbon monoxide, lead, oxides of nitrogen (NOx), volatile organic compounds (VOCs), sulfur dioxide (SO 2 ), carbon dioxide (CO 2 ), fine particles and other toxic chemicals. These pollutants affect the plant growth and physiological behavior of vegetation in urban area (Durrani et al 2004;Chauhan 2010;Narwaria and Kush 2012;Wittenberghe et al 2013). Additionally, the urban conditions near roadsides also have impacts on photosynthetic pigments, activities related to respiration, enzymatic activities at metabolic level, gas exchange and stomatal physiology, etc.…”

The mitigation potential of avenue tree species needs a sound understanding, especially for landscape planning or planting tree species on roadside, especially in city limits where there is huge traffic due to more number of vehicles. A preliminary study was conducted to investigate the impact of heavy traffic movement and pollution thereof on physiological functioning of Lagerstroemia speciosa trees planted on roadside in terms of carbon absorption, mitigation potential and adaptive behavior. Trees on roadside exhibited reduced carbon assimilation (36.7 ± 2.4%) and transpiration rate (42.14 ± 2.9%), decreased stomatal conductance (66.85 ± 3.87%), increased stomatal resistance (212.2 ± 11.25%), more leaf thickness (40.54 ± 3.25) and water use efficiency (9.4 ± 0.87%), and changes in lead (179.31 ± 10.24%) and proline (15.61 ± 1.92%) concentration in leaf tissues when compared to less traffic area (FRI campus). The impacts were also witnessed in the form of enhanced vapour pressure deficit of air (63.18 ± 4.94%) and leaf (45.72 ± 3.25%), and air temperature (3.2 ± 0.16%) and leaf temperature (9.0 ± 0.82%) along roadside trees. It was inferred that heavy traffic movements interrupt the physiological functioning of trees due to alteration in the surrounding environment as compared to non-traffic areas. The present study provides baseline information to further explore and identify the potential avenue tree species having significant mitigation potential and adaptive efficiency to heavy traffic movements for improving urban environment.

“…[1][2][3][4][5][6][7][8][9][10] This has greatly stimulated the interest in polymer/surfactant system and investigation of interactions among them has become the major issue in these days. 2,[3][4][5][6][7][8][9][10][11][12][13] Neutral water-soluble polymers are considered to be less complicated than charged ones. Nevertheless, the interaction between neutral polymers and surfactants is less well understood and needs further investigation.…”

Micellization behavior of sodium dodecyl sulfate (SDS) and its mixture with polyethylene oxide (PEO) are investigated using surface tension and light scattering techniques. The data are presented and interpreted in a novel way, which provides more and reliable information about the interaction of the components. The concentration of SDS corresponding to the initiation of interaction with PEO (T 1 ) and the saturation point (T 3 ) are well identified in this way. It has been observed that the concentration span between T 1 and T 3 is not much affected by the amount of PEO added. The detail investigation of data concludes that SDS and PEO interactions are in one to one ratio at molecular level and CMC decreases with the addition of salt to the system and the micelles become more compact.
