The paper presents the results of air quality impact assessment carried out for the Municipal Solid Waste Disposal Plant in Warsaw. As part of the plant is working so far the only municipal solid waste incinerator in Poland. Following the evaluation, including data for the year 2008, it was found that it is a minor source of emissions to air and causes a slight air pollution. The highest maximum one-hour and annual average concentrations caused at ground level are many times lower than the respective reference (or permissible) values and background values for analyzed substances in the air. Increasing the …

The paper presents an assessment of the impact of waste co-combustion in a cement kiln on air emissions of HCl and SO2 recorded continuously. The subject of the research was cement kiln (dry method) with a capacity of 8500 Mg/day, equipped with a four cyclone heat exchangers and a calciner with an additional chamber for co-incineration. In the analysed period alternative fuels (mainly waste) were used in various amounts ranging up to about 35 kg / Mg clinker (with the heat substitution up to 20%) in the kiln and calciner. Chlorine and sulfur inputs to the process were up to …
The Costs Of Residential Water Scarcity In Cyprus: Impact Of Climate Change And Policy Options, Theodoros Zachariadis
The Costs Of Residential Water Scarcity In Cyprus: Impact Of Climate Change And Policy Options, Theodoros Zachariadis
Theodoros Zachariadis
This paper presents an assessment of the costs of water scarcity in Cyprus, today and in the next twenty years, accounting also for the effect of projected climate change in the region. We focus on the residential sector, accounting also for tourism and industry. Using a simple demand function we first compute total scarcity costs in Cyprus for the entire period 2010¡V2030 for three scenarios of future water demand. Our central estimate shows that the present value of total costs due to water shortages in this period will amount to 72 million Euros (at 2009 prices), and if future water …
Assessment Of The Impact Of Using Alternative Fuels In A Cement Kiln On The Emissions Of Selected Substances Into The Air, Robert Oleniacz
Assessment Of The Impact Of Using Alternative Fuels In A Cement Kiln On The Emissions Of Selected Substances Into The Air, Robert Oleniacz
Robert Oleniacz
The chapter presents the results of analyses concerning the impact of using alternative fuels in one of the Polish cement plants on the volume of continuously measured emissions into the air for the following substances: carbon dioxide (CO2), carbon monoxide (CO), nitric oxides (NOx), sulphur dioxide (SO2), hydrogen chloride (HCl), gaseous and volatile organic compounds expressed as total organic carbon (TOC), and total dust. The analyses covered a 15-month period of the operation of a dry cement kiln, approximately 100m-long, equipped with four-stage cyclone exchangers and a calciner, constituting an additional chamber for waste co-combustion. The results obtained confirmed the …

The baking of semi-finished graphite products in a tunnel furnace is the source of many air pollutants present in both the gaseous and solid phases. The goal of this study was to assess emission rates into the air of the substances such as: CO, NOx, SO2, H2S, CH4, aliphatic hydrocarbons up to C6, benzene and its homologues (BTEX), total dust and tar substances, and polycyclic aromatic hydrocarbons (PAHs) contained in the dust. The research showed a small time-dependence of the emission rates for the majority of the substances analysed, which is, to a large extent, a result of the long …

This study investigates the thermal variations of the different land use/cover types in urban Lokoja town retrieved from Landsat TM imagery of 1987. Band 2, 3, 4 and 6 of the imagery were used in the classification, estimation of NDVI, land surface emissivity values, and satellite sensor temperature. The Qin et al’s mono window algorithm was employed to obtain the land surface temperatures of the different land use/cover types classified. The results indicate that there is a significant variation in temperatures among the different land use/cover types in Lokoja. The built up area and the vacant area have the highest …

The objective of this work is to present a critical review of the application of the tissue residue approach (TRA) in ecological risk and/or impact assessment (ERA) of chemical stressors and environmental criteria development. A secondary goal is to develop a framework for integrating the TRA into ecological assessments along with traditional, exposure concentration-based assessment approaches. Although widely recognized for its toxicological appeal, the utility of the TRA in specific applications will depend on numerous factors, such as chemical properties, exposure characteristics, assessment type, availability of tissue residue-response data, and ability to quantify chemical exposure. Therefore, the decision to use …

Meeting The Common Needs Of A More Effective And Efficient Testing And Assessment Paradigm For Chemical Risk Management, Steven P. Bradbury, Vicki Dellarco, Tala Henry, Phil Sayre, Jennifer Seed

Significant advances have been made in human health and ecological risk assessment over the last decade. Substantial challenges, however, remain in providing credible scientific information in a timely and efficient manner to support chemical risk assessment and management decisions. A major challenge confronting risk managers is the need for critical information to address risk uncertainties in large chemical inventories such as high- and medium-production-volume industrial chemicals or pesticide inert ingredients. From a strategic and tactical viewpoint, an integrated approach that relies on all existing knowledge and uses a range of methods, including those from emerging and novel technologies, is needed …

Impact Of A Large Medical Waste Incinerator On Air Quality, Robert Oleniacz
Impact Of A Large Medical Waste Incinerator On Air Quality, Robert Oleniacz
Robert Oleniacz
In the paper, an assessment of the compliance with air emission limit values and the impact on air quality of one of the largest medical waste incinerators in Poland, with a total capacity of about 300 kg/h (two incineration lines) is presented. The assessment took the results of continuous and periodic measurements of emissions in the plant’s installation over a period of 12 months’ operation into account. For this period, a calculation was performed for the spread of air pollutants emitted by the two operating incineration lines. According to the analysis and calculations, the analysed medical waste incineration plant does …
