BIO-MONITORING OF ROADSIDE PLANTS AND THEIR RESPONSE TO VEHICULAR POLLUTION- A PHYSIOCHEMICAL APPRAISAL.

Abstract In recent times, highly developed metropolitan cities have progressively used biodiverse roadside plants as an eco-sustainable tool for the mitigation of air pollution. The present study has been designed to scrutinize the impact of particulate matter (PM) deposition and heavy metal accumulation in roadside plants. Some of the common roadside plants found along the national highway at Thane (Mumbai) region that were selected for this study are Alstonia schlolaris, Bauhinia variegata, Ficus benghalensis, Ficus religiosa, Cassia fistula, and Mangifera indica. The inductively coupled plasma atomic emission spectroscopy (ICP-AES) analysis was carried out for five heavy metals, namely Cr, Cu, Fe, Mn and Zn. The particulate matter deposition was observed to be the highest in Ficus benghalensis (1.14 mg kg−1), while it was found to be the lowest in Bauhinia variegata (0.71 mg kg−1). The present study revealed that the accumulation of heavy metals in plants inversely varies with the deposition of dust on the surface of leaves. The tolerant species of plants can serve as natural biofilters that can alleviate environmental pollution to certain extent.

A bio-monitoring system for toxicants in water has been developed and verified for actual applications. This system is based on the motionality of five Acheilognathus lanceolata, a fish known to be very sensitive to toxic substances, moving around in an aquarium. Their movements are continuously monitored with a charge coupled device (CCD) camera and analyzed to find and quantify any abnormal behavior in their motional characteristics in comparison with the pre-acquired data. That is, the images of fish captured by a CCD camera are digitalized to identify the location of fish in a constant time interval and the locations of each fish were then analyzed mathematically with a personal computer using the equations proposed to determine the motional characteristics such as floatness, fledness and mobility(agility). These data are then converted by means of fuzzy estimation to an index value, defined as the contamination index (CI), by which the system provides the information about the overall toxic strength of the toxicant in the water flowing into the aquarium. If the fish are exposed to toxicant(s), the CI value will be proportional to the strength of its toxicity. The pilot test was performed in a water treatment plant for six months in order to verify the reproducibility of the system over the unstable conditions such as highly turbid water after rainfall as well as in normal conditions. The test results revealed that this monitoring system has good reproducibility and sensitivity, proving our approach, described in this paper, is reliable. As a result, this approach seems to enable us to make a quick and easy detection of toxic substances contained in water, therefore, this system can be applied to a source of water supply as a toxicant watching system.

Moringa Oleifera Lam

Moringa oleifera Lam., commonly found tree in sub-Himalayan tracts of India, Pakistan, Bangladesh and Afghanistan has a high nutrition value. The leaves, flowers and immature pods of Moringa are used as a vegetable in many countries. The leaves are highly nutritious and medicinal in nature. They are a rich source of iron, calcium, vitamin A, vitamin C, proteins, and essential amino acids. Hence Moringa leaves can be a good source of protein for the vegetarians and the under-nourished population. Present investigation deals with the study of monthly variation in the nutritional value of Moringa leaves from the month of June 2015 to January 2016. Impact of urban sewage pollution and roadside vehicular pollution on the amount of reducing and total sugars, chlorophylls (a, b and total), proteins, vitamin-C and pH of the leaves, was also studied. Results revealed that the highest amounts of reducing sugars, total sugars, chlorophyll b and total chlorophyll during October 2015 whereas proteins, chlorophyll a, vitamin C and pH were highest during January 2016. Leaf samples collected from all the study sites exhibited minimum amounts of reducing sugars, chlorophylls (a, b and total) and pH during July 2015 whereas total sugars were lowest during December 2015. Proteins and vitamin C values were lowest during August and June 2015 respectively. Sewage and vehicular pollution showed an adverse effect on the nutritional contents of Moringa oleifera leaves. Of the two polluted sites, samples from near the sewage flow showed higher impact.

Bio Monitoring

This work aims to assess the spatial and temporal variations of four biomarkers activities and to integrate their biological responses in a battery using the gastropod Phorcus turbinatus. The monitoring was carried out during the period between April 2014 and January 2015 at six stations along the northern and the northeastern coasts of Tunisia. The Fulton condition factor was estimated and the activities of catalase, acetylcholinesterase and glutathione-S-transferase were evaluated by spectrophotometry. A multi-biomarker battery approach was used to assess ecosystems’ condition and to identify environmental impacts on the organisms. The results suggest that the enzymatic activities of CAT and GST depend especially on seasons. As for AChE activity, it was similar between seasons and stations. The values of the integrated biological response were maximal at Jarzouna in summer and at Sidi Daoued in winter, indicating the presence of severe stressors suffered by the organisms. This perturbation may be due to the enrichment of the waters by xenobiotics, namely polycyclic aromatic hydrocarbons, insecticides, phosphate wastes, PCBs and pesticides. Thus, P. turbinatus seems to be a good bioindicator of chemical pollution, constituting an adequate tool for a bio-monitoring program.

AbstractThis study was undertaken to examine changes in the content of pigments and accumulation of metals from vehicular pollution in selected species of roadside trees under vehicular pollution. A major arterial road with heavy vehicle emissions in the Kumasi Metropolis was designated as the polluted site, while Kwame Nkrumah University of Science and Technology Campus was designated as the control site. Four tree species (Terminalia catappa, Mangifera indica, Ficus platyphylla and Polyalthia longifolia) selected for the study were well distributed and abundant in the polluted and control sites. Photosynthetic pigments and levels of heavy metals (Pb, Cu, Cd and zinc) were assessed in their leaves. Chlorophyll and carotenoid contents were determined by absorption spectrometry, while the metal accumulation index (MAI) was used to determine the total metal accumulation capacity of the tree species. We observed a reduction in photosynthetic pigments in the leaf samples from the polluted site. Ficus platyphylla had the maximum reduction in total chlorophyll (49.34%), whereas Terminalia catappa recorded the lowest reduction (33.88%). Similarly, the largest decrease (31.58%) of carotenoid content was found in Terminalia catappa trees and the lowest in Polyalthia longifolia (16.67%). The Polyalthia longifolia, Ficus platyphylla and Terminalia catappa leaf samples collected at the polluted site recorded a higher ratio of chlorophyll a/b. Heavy metal (Cu, Pb, Zn and Cd) accumulation in leaf samples was higher in the polluted site than in the control, as expected. The highest metal MAI value was recorded in Mangifera indica (5.35) followed by Polyalthia longifolia with 4.30. The findings from this study specifically demonstrate that air contamination induced by vehicles decreases the level of photosynthetic pigments in trees subjected to roadside emissions. It is clear that both chlorophyll a/b and chlorophyll/carotenoid ratios will act as very useful stress-level markers. Elevated heavy metal levels in the tree species along arterial roadsides indicate that they serve as heavy metals sink. The change in MAI resulting from different pollution burden is an indication that the removal capabilities of the tree species differ from each other. We therefore suggest M. indica and P. longifolia as potential species to be used in air pollution reduction plans in the city.
