  • Monitoring Multiple Gas Hazards in Ice Arenas

    The equipment used in an arena such as an ice re-surfacer, ice edger, floor sweepers, lift trucks and other special equipment are more often powered by fuel than electricity. The exhaust produced by the gas, propane or diesel fuel powered machines emits, into the air, carbon monoxide (CO), nitrogen dioxide (NO2) and particulates. Ammonia (NH3) is commonly used in the ice chiller mechanical room ...

  • Estimating changes in river faecal coliform loading using nonparametric multiplicative regression

    Faecal coliform (FC) concentration was monitored weekly in the Tangipahoa River over an eight year period. Available USGS discharge and precipitation data were used to construct a nonparametric multiplicative regression (NPMR) model for both forecasting and backcasting of FC density. NPMR backcasting and forecasting of FC allowed for estimation of concentration for any flow regime. During this ...

  • Indicators of Pollution Management

    'The definition and selection of environmental performance indicators is still at an early stage but the use of indicators is increasing, both for the tracking of trends in pollution and other environmental issues at a large scale (national or regional) and also for the monitoring of Bank projects. This note provides a framework to assist in the selection of appropriate indicators for pollution ...


  • Specificity of a defined substrate method used to monitor balneability of tropical coastal waters impacted by polluted stormwater

    Defined substrate (DS) is an alternative technique to monitoring the water quality based on species-specific enzyme activity. Although more sensitive and more specific than traditional media, there is some controversy over use in the warmer waters of tropical and subtropical environments, rich in organic matter and microorganism groups capable of interfering with results. The aim of this study ...

  • Source apportionment of PM2.5 in urban areas using multiple linear regression as an inverse modelling technique

    One method to assess the source contribution of particulate matter to urban air quality is through inverse modelling where emissions are estimated using dispersion models and monitoring data. In this paper, a straightforward inverse modelling method, using Multiple Linear Regression, is described and applied to the urban area of Oslo for PM2.5. The results of the inverse ...

  • Replacement of a Multiple Hearth by a Fluid Bed Incinerator - The Greensboro Experience (PDF - File size 50K)

    ABSTRACT The incinerator at the T.Z. Osborne Plant in Greensboro, North Carolina burns sludge from its own Waste Water Treatment Plant and sludge pumped from the nearby North Buffalo plant. The two plants have a combined capacity of 36 million gallons per day of wastewater. In 1992, the Osborne plant concluded a study evaluating its options for future municipal sewage sludge disposal. The ...

  • Air Pollution Control in the Printing and Web Coating Industries

    For many U.S. companies in the printing and web coating business, the use of an Air Pollution Control System (APCS) to control harmful air pollutants is not new.  In these industries, depending upon their location, companies have been installing APCS since the early 1970's.  However, for some companies the clock is still ticking regarding their compliance with local, state and federal ...

  • Urban Noise Monitoring in Madrid

    Dynamic mapping helps Madrid improve the quality of life for her citizens and visitors alike. With its 3 000 000 inhabitants and 2500 km of streets, Madrid is an excellent example of what can be done to improve human comfort related to urban noise. Since the late 60s, Madrid City Council has been working on noise problems. During this period, global environmental analysis has focused on how ...

  • Estimation of the exchange of sulphur pollution over the Balkan region in 1995?2000

    The Bulgarian dispersion model 'Eulerian Model for Air Pollution' (EMAP) is used to estimate the sulphur pollution over the Balkan region for the period 1995?2000. A subdomain of the European Monitoring and Evaluation Programme (EMEP) grid is chosen containing 12 countries. The computational grid in this domain has a space step of 25 km, twice as fine as the EMEP grid. The former operational DWD ...

  • Double benefit of monitoring Indoor Air Quality (IAQ)

    It is a difficult balance to save money and energy yet maintain a comfortable and healthy indoor air environment. A logical solution to controlling indoor air pollution is good ventilation coupled with IAQ monitoring using gas sensors. This can ensure healthy indoor air as well as a more efficient HVAC system.  Typical IAQ investigation and examination consists of taking single-point ...

  • In-situ continuous emissions monitoring & regulatory compliance

    As environmental scrutiny has risen and regulation has tightened in recent years, the importance of having accurate information on the environmental performance of your power plant has increased. After all, if you want to manage something, you need to be able to measure it. The analogy is obvious; you wouldn't start a diet without first investing in a set of scales. So it is with Continuous ...

  • On site flotation for recovering polluted aquatic systems: is it a feasible solution for a Brazilian urban river?

    Pinheiros River (Brazil) plays a pivotal role in supplying water to Billings Reservoir, which presents multiple uses (human drinking, energy generation, irrigation, navigation, fishing and leisure). An intense monitoring program was performed during the years 2007 and 2008 to find out whether on site flotation is a feasible solution or not for improving the water quality of this urban river, ...
