The present study deals with the effect of urbanization and automobile emission on ambient air quality of Bhubaneswar city, Odisha. This paper examines the significant difference in seasonal variations of air pollutant concentrations in the city. RSPM (respirable suspended particulate matter), SPM (suspended particulate mater), sulphur dioxide (SO2), oxides of nitrogen (NOx) and CO were collected at 5 sites in Bhubaneswar. Monthly and seasonal variation of these pollutants are compared graphically for 2 consecutive year from November-08 to October-10. The annual average and range values have also been calculated. Using observed annual means and standard values of different parameters the exceedence factor for each pollutant was calculated in all selected locations. It has been observed that the concentrations of the pollutants are high in winter in comparison to summer or rainy seasons. In the present study it was noticed that the SPM, RSPM and CO levels at all selected sites exceeds the prescribed limits as stipulated by Central Pollution Control Board (CPCB). But the SO2 and NOx levels at all the sites found under prescribed limits of CPCB. From exceedence factor, the different pollutants are categorized into 4 categories. It was observed that RSPM at all locations for both the years fall under critical category. SPM in 2008-09 fall under critical category at 3 locations and rest 2 under high category. In 2009-10 SPM fall under high category for 4 locations and one location under critical category. SO2 at all locations in both the years are under low category. NOx in 2008-09 fall under moderate category at 3 locations and rest 2 locations in low category while in 2009-10 all locations fall under moderate category. CO in 2008-09 fall under critical category at 2 locations, high category at 2 locations and moderate at one location but in 2009-10 falls under critical category at 2 locations, high category at 2 locations and moderate at one location. © 2012 - Kalpana Corporation.

Due to rapid urbanization of Bhubaneswar city, the population load is increasing sharply day by day. As a result ,the requirement of water for human activities is increasing. In return a huge amount of wastewater is generated and discharged into river Kuakhal and make it polluted. Thus people are forced to use ground water which is known to be safe for drinking. At present 40% people of Bhubaneswar depend on ground water. But unfortunately the ground water Is also getting polluted day by day. So it is high time to assess the ground water quality in Bhubaneswar. Nine different locations were chosen depending on population load and to cover all parts of Bhubaneswar .The samples were collected quarterly in the month of January-09, May-09 and September-09 to determine different physical, chemical and biological parameters. The seasonal variations of different parameters have been compared with the standard. From the results mean, standard deviation; correlation coefficient among different parameters has been studied. It is found that total hardness is highly correlated with chloride, conductivity and total dissolved solids. Similarly chloride is highly correlated with conductivity and total dissolved solids. Conductivity and total dissolved solids are highly correlated. The results are compared with standard values. © 2011 - Kalpana Corporation.

The chronic air pollution blanketing much of northern India is now threatening the holiest shrine in the Sikh religion, making the once-gleaming walls of the Golden Temple dingy and dull. There is little to be done short of replacing the 430-year-old temple's gold-plated walls — an expensive project already undertaken more than a century ago and then again in 1999. To cut down on pollution, environmentalists and religious leaders have launched a campaign that includes persuading farmers to stop burning spent crops to clear their fields, removing industry from the area and cutting back on traffic. A community kitchen called a "langar" that serves up to 100,000 people free meals every day at the temple is also switching from burning wood to cooking with gas. But so far the campaign hasn't had much impact, with change happening slowly and still no pollution monitoring equipment installed. "As far as pollution goes, we are paying attention," said Jaswant Singh, environmental engineer at the State Pollution Control Board, a government regulatory authority. "We are in the process of procuring equipment so that we can check the pollution area, pollution from every source on a day-to-day basis." Officials have also banned burning trash or cooking with certain fuels in restaurants and communities nearby, but enforcement so far remains weak. The city also wants to build an electricity station to stop people from using diesel-fueled generators, but Singh could not say when that might happen. "The pollution degrading the Golden Temple is growing," said environmental activist Gunbir Singh, who heads a group called Eco Amritsar. "We need to do a hell of a lot of work to protect the holy city status of this city." It's unclear how much replacing the gold plating would cost, but it would surely be high. "This is gold. The cost would be huge, but still would not be a problem," Gunbir Singh said, suggesting Sikh devotees would rally behind the cause if needed. "Most of the activity that goes on there is based on donations — people will take off their bangles and rings and leave them if work needs to be done." Thousands of Sikh devotees and tourists every day visit Amritsar, the main city in Punjab state, to see the 17th century shrine, surrounded by a moat known as the "pool of nectar," or "Sarovar," and housing the Sikh holy book, the Guru Granth Sahib. Most of the world's 27 million Sikhs, whose monotheistic religion originated in Punjab in the 15th century, live in India. The country suffers some of the world's worst air pollution, thanks to a heavy reliance on burning coal for electricity, diesel in cars and power generators, and kerosene and cow dung for cooking and lighting homes. Heavy construction amid a decade-long economic boom has also kicked up huge clouds of dust, and farmers still regularly clear their fields with fire, sending even more black carbon into the air. The capital of New Delhi was named by the WHO as the world's most polluted city, while Amritsar — about 390 kilometers (240 km) to the north — was ranked India's ninth most polluted. The Golden Temple is not the only major monument to be affected by pollution. The white marbled Taj Mahal has also become dirty from pollution from the nearby city of Agra, and every few years, workers from the Archaological Survey of India place mud packs on its walls to keep them from turning yellow and brown. But many across the country remain unaware of the risks in breathing unhealthy air, even as scientists warn it is sickening countless Indians every year. About 1.4 million Indians were killed by illnesses related to air pollution in 2013, according to a recent study by researchers at the University of British Colombia, in Vancouver. That tally will only rise unless pollution levels are drastically curbed, experts have said. Instead, the pollution is getting worse, according to NASA satellite images revealing particulate matter in the air. An analysis last month by the environmental group Greenpeace showed the overall concentration of PM2.5 — the tiny lung-clogging particulate matter suspended in the air — increasing 13 percent from 2010 to 2015. With pollution fast damaging the Golden Temple, some in the Sikh heartland said they were reminded of their religious duty to protect nature. "Our holy book teaches us that the air is the teacher, the water is the father and the earth is the mother. So we have to be mindful of all the elements of nature as true Sikhs," the environmentalist Gunbir Singh said. Authorities plan to ban vehicles from the area immediately surrounding the shrine. "Even the devotees will have to come on foot," said Harcharan Singh, who heads the Shrimoni Gurudwara Prabhandak Committee, which oversees the six major Sikh temples across India. But efforts have been slow, and officials admit so far incomplete. Sikh preacher Baba Sewa Singh said he and his devotees have tried to help mitigate the pollution threat by planting more than 100,000 trees in the region. "If anyone asks about the saplings," he said, "we plant then for free in their villages."

The gold-plated walls of India's Golden Temple once gleamed brightly, but chronic air pollution is making its walls grimy and dull. Is this the end of the "golden" era for one of the holiest Sikh shrines? Unfortunately, the problem cannot be solved with just elbow grease. The walls of the 430-year-old temple requires an overhaul. This expensive development started more than a century ago and resumed in 1999. "The pollution degrading the Golden Temple is growing. We need to do a hell of a lot of work to protect the holy city status of this city," said Gunbir Singh, an environmentalist and Eco Amritsar leader. While it remains unclear how much the gold replacement project will cost, it is expected to be high. However, Singh said that the cost would not be a problem, highlighting that the majority of the temple activities are based on donations. He also suggested that Sikh devotees would support the cause and donate their rings and bangles if needed. Environmentalists, as well as religious leaders, started a campaign to help reduce the country's air pollution. Some of their efforts include cooking with gas instead of burning wood inside the temple's "langar." Every day, this community kitchen prepares and serves food to 100,000 people for free. Leaders also urged farmers not to burn spent crops during their field-clearing activities. Managing the traffic and removing industries near the temple are also part of the recent campaign, which is not doing so well. The changes are slow and to date, no equipment has been installed to monitor air pollution levels. "As far as pollution goes, we are paying attention. We are in the process of procuring equipment so that we can check the pollution area, pollution from every source on a day-to-day basis," said Jaswant Singh an environmental engineer from the State Pollution Control Board. Officials also made it illegal to cook with specific fuels in communities and restaurants near the Golden Temple and banned the burning of trash. The city plans to come up with an electricity station to prevent people from using generators powered by diesel fuel. However, there is still no date as to when this electricity station will be built and so far, the enforcement of these recent rules is weak, according to an Associated Press report.

A study has been taken to evaluate the impact of industrial waste generated from different industries existing in Jagatpur Industrial Estate on river Mahanadi. Samples were collected from final discharge point to river Mahanadi of different industries as well as upstream and downstream of river Mahanadi to Jagatpur Industrial Estate. Samples were collected in three seasons. The results obtained at U/S and D/S points on river Mahanadi in different seasons (winter, summer and rainy) has been compared graphically. From the seasonal variation it was observed that almost all parameters are in increasing trend. In the rainy season, yearly average value at the D/S point is quite high as compared to yearly value at U/S point. The high values in rainy season is due to washing of waste dumping near Mahanadi bed. Quality Ratings for different parameters has been calculated from that water quality index was found out and compared. From the results it is concluded that, due to industrial waste discharge, water quality of river Mahanadi is deteriorated at the D/S point on river Mahanadi and the results are not meeting the prescribed standard for drinking water under Class A.

Ground water acts as a reservoir and source of water for wells, springs, bore wells and handpumps. The increase in human population and fast development led to the scarcity of drinking water. The inadequate and irregular supply of water through piped water system has forced the population to use the ground water especially bore wells. As the bore well is used for drinking purpose by most of the population, it is very essential to test the quality of water. The study was carried out by collection of ground water samples from about 6 bore wells located in Jagatpur Industrial Estate area. The samples were collected quarterly In the month of January 09, May 09 and September 09 to determine the different parameters, such as pH, total dissolved solids, BOD, COD, Cl -, T. Fe, turbidity, SO -2, total hardness. Seasonal variations of different parameters have been compared with the standard. From the results mean, standard deviation and correlation, coefficient among parameters has been studied. © 2011 - Kalpana Corporation.

India's coal demand is expected to increase with the setting up of more and more coal based power projects and to meet the demand from metallurgical and other industries. Indian coals being of drift origin contain as high as 40% ash in some cases. The coal is, therefore, required to be washed in coal washing plants so that the ash content is brought to an acceptable level, before being utilsed by the industries. However, coal washing processes, unless properly handled, has the potential of generating large quantities of pollutants and may cause pollution of air, water and soil. Coal washing, therefore, has become an important area of concern from the economic and environment point of view. In the present paper, a review of the environmental impacts of coal washeries and the possible mitigation measures has been presented. © 2011 - Kalpana Corporation.

In recent years municipal solid waste (MSW) management has been one of the most environmental concerns for all urban areas of India. Most of the urban centers have neither adequate land nor any facility for MSW disposal. In view of scarcity of lands for making landfill sites, solid wastes can be used for energy recovery resulting in volume reduction, thus requires less area for its disposal. Guwahati is one such city of North-East India, having the potential to recover the energy from solid wastes and at the same time the waste management system of the city can be improved. This paper attempts to characterize the urban solid waste of the city as well as its energy potential for various uses. Results showed that the average generation rate of MSW was 0.7 kg/capita/day and the city has the potential to generate the power of 30 MW from the solid waste. © 2012 Journal of Urban and Environmental Engineering (JUEE).
