Airborne concentrations of copper (Cu) and zinc (Zn) in suspended particulate matter (SPM) have been measured at three urban sites in Pital Nagri (brass city) of India over a period of one year, i.e. August 2006 to July 2007. Analysis of samples was carried out by the atomic absorption spectrophotometer. A comparison was made between the sites and concluded that the maximum concentrations of SPM (762μgm -3), Cu (56.01 μgm -3) and Zn (72.15μgm -3) were found at industrial site and minimum at residential (200μgm -3,2. 10μgm -3 and 1.65ugm3) site respectively. A seasonal variation in concentrations was also observed. In this paper, an attempt has been made to identify the various sources responsible for the high level of toxicity and it has been concluded that brass industries are mainly responsible for the enhanced concentration of these two metals.

Samples of suspended particulate matter (PM10) were collected from three different sites in Moradabad; India. The sampling was done concurrently twice a week during the period of April 2011-March 2012. Elemental concentration of PM10 was analyzed using an Inductively Coupled Plasma Optical Emission Spectrophotometer (ICP-OES). The monthly mean concentration of PM10 (RSPM) ranged between 63-226μgm -3, which was higher than the permissible limit of 100|jgm3 of National Ambient Air Quality Standards. The maximum concentration of Zn, Fe, Cu, Cr and Ni found in the Industrial area of the city was 21.24,18.43,15.23,0.41, 0.03μgm-3, respectively; whereas the maximum concentration of Pb (2.72μgm-3) and Cd (0.20μgm-3) was found in heavy density traffic area, denoted as commercial area. The study shows that high number of vehicles and the brassware industries are responsible for enhanced concentration of heavy metals in the Brass City. © Triveni Enterprises, Lucknow (India).

The present study deals with the assessment of ambient air quality index with respect to suspended particulate matter (SPM), sulphur dioxide (SO 2) and nitrogen dioxide (NO2) considered over a period of one year from March 2007 to Feb. 2008. The air quality index has been determined at three different sites, i.e. PTC(SI), Town hall(SII) and Mughalpura (SIII) of Moradabad city. The experimental results obtained from the different air quality categories according to National Ambient Air quality Standard at different site as SI(45.38) shows slight air pollution, SII(99.39) high air pollution and SIII (117.87) shows very high air pollution.

The present investigation was undertaken to assess the atmospheric lead pollution on the highway and its effect on the leaves of some avenue trees. Emission of lead from the automobile exhaust contaminates soil and surrounding plants. Samples of unwashed leaves were used to assess the concentration level of lead(Pb) in plants and for the purpose the leaves of five different avenue plant species i.e. Holoptelea integrifolia , Ficus rumphii, Anthocephalus kadamba, Alstonia scholaris and Bauhinia variegata were collected from five different locations and were analyzed by ICP. The results indicate that among the plants Bauhinia variegata have the highest concentration of lead (1.81μgg-1) at unpolluted site as well as at polluted site (4.56μgg-1) while Holoptelea intagrifolia the have the lowest (1.01 μgg-1) at unpolluted site compared to the polluted site (2.94μgg-1) possibly due to difference in plant morphology and leaf surfaces. On this basis it may be concluded that Holoptalea integrifolia, Ficus rumphii and Anthocephalus kadamba, are the resistant cultivars and may be grown as avenue trees near highways. © 2010 The Academy of Environmental Biology.

Background: The previous studies reveal that the burning of crackers and sparklers on the occasion of Deepawali (Diwali) is a strong source of air pollution and may cause serious health hazards. Since fireworks displays are becoming more frequent and can influence the ambient air quality by Particulate Matter (PM), SO2, NO2 and trace elements, we examine the effect of firework during Diwali festival. Subject and Methods: The effect of the burning of fireworks on ambient air quality was assessed in Moradabad city during Diwali festival in November 2012 i.e. one week before Diwali, on Diwali and one day after Diwali day. The monitoring was carried out using Respirable Dust Sampler (RDS) and Fine Dust Sampler (FDS). Particulate Matter i.e. TSP, PM10 and PM2.5 were estimated by gravimetric method and gaseous pollutants namely SO2 and NO2 were measured by improved West-Geake and Jacob-Hochheiser modified method, respectively. Elemental content of PM10 has also been determined using ICP-OES in samples, taken during Diwali days. Results: The 8 h concentration of TSP, PM10 and PM2.5 on main festival night was found to be 856, 624 and 597 μgm-3, respectively and these concentrations were found to be higher at 2.0, 2.56 and 5.52 times for TSP, PM10 and PM2.5 when compared with the concentration of the respective night of the normal day and was significantly higher (p<0.001). Gaseous concentration SO2 and NO2 was reported about two times higher than the Normal Day. On Diwali day, 24 h values for TSP, PM10, PM2.5, SO2 and NO2 were found to be higher than prescribed limit of National Ambient Air Quality Standard (NAAQS). The 24 h mean concentration of metals associated with PM10 on Diwali day was found to be in the order of Zn (17.74)>Al (13.36)> Fe (12.47)> Cu (10.47)> Pb (2.54)> Mn (0.42)> Cr (0.19)> Cd (0.18)> Ni (0.15) in μgm-3 and all these values were found to be higher (except Fe) than the normal day and post Diwali day. Correlation study shows a strong positive correlation between Cr with Cu and Cu with Zn. Lead and cadmium are known to have adverse effects on cardiovascular health. Conclusion: It is possible that the burning of fireworks during Diwali festival may be the major source of emission and accumulation of fine particles in the atmosphere. The inhalation of PM may reach deep into the alveoli of lungs causing adverse effects on health; respiratory and cardiovascular diseases. © Nova Science Publishers, Inc. Source
