The aim of this study was to examine the amounts of heavy metals in the sediment of a wetland constructed for stormwater treatment. The wetland is called Vattenparken and is located in the city of Enköping. The heavy metals which were analysed were Pb, Cd, Ni, Zn, Cu, Cr and Hg. The total metal concentrations were determined using HNO3 chemical extraction. From 8 sampling sites 5 sediment cores were taken.
Miljö- och Personalreglering i Förvaltningsberättelsen : - En studie av Svenska Börsnoterade Företag
The environmental work of companies has become an incredibly important factor in achieving reduced levels of environmental pollution. For companies the work on environmental issues began in the 1980s. During this time companies also began to show interest for the personnel, an interest that was shown in the form of attempts to disclose personnel information in economics. Earlier this information was separated from the financial information, despite the fact that the revenues are created by the employees.The purpose of this paper is to examine how well companies with a notification or a permit today account for environmental- and personnel information in their director?s report.
Ekoturismens inverkan på miljömässiga attityder och beteenden : En kvalitativ studie om individers erfarenhet av valskådning
The purpose of this study is to examine if the experience of whale watching can lead to increased knowledge of environmental problems. We also want to find out whether increased knowledge in turn could lead to changing environmental attitudes and behaviors. The theoretical framework consists of theories about sustainable tourism, ecotourism and responsible environmental behavior. The paper also has a section where previous research on ecotourism impacts on behavior and attitudes is discussed and subsequently addressed in the analysis section.Data has been collected through a case study where seven semi-structured interviews were conducted with individuals who participated in whale watching. The results show that all respondents had greater knowledge of whales by their experiences, the degree of knowledge was due to respondents' prior knowledge.
Miljökonsekvensbeskrivning för en utökning av befintlig djurhållning :
In the last few years the environment becomes more watchful, even for us farmers.
All agricultural enterprises that exceed 200 animal units must be tested according to
regulation of environment. A farm business with 200 animal units and more is classed
?environmentally hazardous activities? and has to make an environmental impact
assessment for the business you have today, and the activity after expansion.
Before you can construct a building and expand the numbers of animals is a lot of
applications to make. I have in this project restricted me to establish a environmental
impact assessment and a consultation foundation.
To make a environmental impact assessment is the big part of the application. The
environmental impact assessment take a lot of time and you need skills for all the rules
in the environmental code to be abele to make an environmental impact assessment
approved.
The environment codes purposes (1 kap 1 § Miljöbalken) is to rule the laws.
The purpose of the environment code is to promote sustainable development which will
assure a healthy and sound environment for present and future generations.
Definitions of a ?environmentally hazardous activities? 9 kap 1§ Miljöbalken) shall
mean the discharges of wastewater, solid matter or gas from land, buildings or structures
onto land or into water areas or ground water.
Globalisering och miljöarbete inom multinationella företag
The environment became an established issue on the international political agenda after World War 2. How to preserve natural resources became an issue that concerned several powerful participants, affected by changed conditions in the environmental legislation. This paper is a study of the growing environmental work within the multinational Swedish corporations Boliden, IKEA and SAS and how it was affected by the globalization. The material studied is environmentally related information produced by the companies and also interviews with the Environmental Managers. The information provided has been analyzed and compared with well-known opinions of globalization, trying to find out how the process of globalization has affected the handling of environmental work within the companies.
Sensorfusion av GPS och IMU för en racingtillämpning
AIMS AB is a Swedish company that develops and sells inertial sensor systems. A new product is under research which basically is an aided inertial navigation system where unwanted drift is eliminated. This can be done by integrating a GPS reciever into the system and fuse measurement data from GPS and IMU. Such a product is useful in racing, where engineers always are searching for the optimal performance and the shortest lap times. Today the only feedback the engineers and mechanics get from their work is the driver?s comments and lap times.
För den goda sakens eller smakens skull?: En studie om vad som driver konsumenter i valet av ekologiskt vin
Concerns for the environment and our impact on it are becoming more prevalant; however, we rarely act accordingly. Consumers mainly choose products based on perceived personal benefits despite the environmental motives that increasingly affect them. The purpose of this thesis is to identify the major drivers behind the purchase of ecological wine. A quantitative study was conducted, using Theory of Planned Behavior (TPB) as an initial starting point. The subsequent model was then completed with three variables: environmental concern, feelings and word-of-mouth.
En vampyr i sitt liv : En studie om elevers syn på gymnasieskolans arbete mot diskriminering, trakasserier och kränkning
The representative democracy has become weakened during the last decades. At the same time the United Nations declared at the Rio de Janeiro meeting in 1992 that environmental problems can best be solved by involvement of all concerned citizens in decision-making. The main purpose of this study has been to examine if citizens panels is a possible way to involve citizens in environmental decision-making and what the outcomes can be. Furthermore the study has investigated what the participation has contributed to environmental politics and how representative the results have been. This has been carried out by investigating the Piteåpanel in the municipality of Piteå by conducting interviews.The result of the study shows that the involvement of the citizens in the decision-making influenced the environmental politics of the municipality.
Utvärdering av miljönytta för olika miljöcertifieringssystem för byggnader : En jämförande fallstudie på Swecos kontor i Stockholm, Göteborg och Malmö
This thesis examines the environmental benefits resulting from the choice of environmental certification scheme, with focus on energy. This was carried out by studying the measures that were implemented as a result of the certification of Sweco's three largest office buildings in Stockholm, Gothenburg and Malmö. The office property in Stockholm has been certified with the Swedish Environmental Building, Gothenburg with the British BREEAM and Malmö with the U.S system LEED.The results from the study indicate that an environmental certification can reduce the energy consumption by up to 59 percent and the water consumption by 20 to 66 percent. However; the interviews, literature study and simulations in MATLAB indicate that the size and scope of these environmental benefits depend on several identified factors: the type of building and its conditions, system selection, grade level, the choice of indicators, the ambition of those involved and when in time the certification process begins. The comparison between Environmental Building, LEED and BREEAM showed that Environmental Building for the office property in Stockholm gave the largest environmental benefit in terms of reduced energy consumption thanks to several large measures.
Hållbarhetsreovisning : the Global Reporting Initiative, erfareheter och framtida scenarior
The history of environmental reporting began in the early 1990?s when some companies included the environmental issue in their annual report. The increased interest of ethical and sustainable investments and demands from different stakeholders conjure a change of the report design. To develop the environmental reports and create design guidance for sustainability reports an organisation called Global Reporting Initiative (GRI) was born. The GRI is environmental reporting taken to another level, a level that is according to sustainable development.
Effektiva Institutioner eller Symboliska Samarbeten? En jämförande analys av effektiviteten hos Helcom och Medelhavsregimen
The aim of this thesis is to examine the institutional effectiveness of the environmental institutions Helcom and the Mediterranean regime, by using Haas, Levy and Keohane's "the three Cs"; governmental concern, contractual environment, political and administrative capacity. The method used is a comparative analysis.This study takes into consideration the specific structural and economic factors that are prevailing in each region where the environmental regime operates. This study also takes into account the influence of the European Union as a factor that affects the environmental progress.By focusing the study on the line of conduct concerning hazardous substances by respectively regime this study shows that the institutional effectiveness is fulfilled in neither Helcom nor the Mediterranean Regime, although Helcom has been more successful. The lack of state capacity is the most restraining factor for both developing countries and countries in the transition towards being developed, to achieve a good environmental status of the sea. This study also shows that the European Union sometimes has a greater impact on the environmental progress in states, rather than the environmental regime in countries that were/are aspiring members, thus showing the ineffectiveness of the regime..
Modellering av reflektans från ett sockerbetsbestånd med hjälp av en strålningsmodell
The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has beenused to simulate the reflectance of a sugarbeet canopy. The simulated reflectancevalues show high absorptance in the VIS area, compared to field measurements, andhigh reflectance values in the NIR area. The errors may be due to overestimation ofclorophyll content in the sugarbeet leaves and scattered light during fieldmeasurements. The estimation of the clorophyll content where carried out using thePROSPECT-model by Jacquemoud & Baret (1990).During the vegetation period, the state of the canopy moves towards a closed canopy,with sparse vegetation in spring. The MCRM-model was used to perform a ?spring?simulation, which was compared to the original simulation.
Spring ikapp omvärlden ? en studie om omvärldsbevakning i friskvårdsbranschen
The aim of this thesis is to investigate how small organisations within the subject field health and training work with their environmental scanning. The main questions in this thesis are: How do the organisations work with business intelligence/environmental scanning? What is their environment like and of which parts does it consist? How extensive is their work with business intelligence/ environmental scanning? Which are their main fields of application and how is the work compiled practically? In order to answer these questions we have chosen to use a qualitative method, which in our case consists of two interviews with people in managerial positions within the health and training subject field. The result of the two interviews is presented in a compilation, and it is thereafter discussed and analyzed. We used an existing theoretical model and altered it in order to correspond to the aim of this research..
Svinnoptimering VTIS1
The goals of this Bachelors? Thesis were to establish the production loss through the VTIS1 Pasteur at Arla Foods Linköping dairy and then suggest simple but effective solutions to minimize the losses for each production run. If the timeframe allowed it, some of the solutions would be implemented and tested in full production to determine their impact on economic and environmental savings.The very first step of this project was to establish the statistics over what losses there is in the production pipeline through VTIS1, from milk and powders in mixer tanks to finished and packed products in cold storage. Then, when knowing how much product was actually lost and where, those bottlenecks could be pinpointed and examined more closely. At this stage the focus was switched, from the otherwise complicated and broad manufacturing process, to the VTIS1-aggregate, since early data indicated there were quite substantial losses there.In conjunction with this project Arla Foods purchased an absorption photometer-measuring device (OPTEK AS16) that could be inserted straight into the product stream out of VTIS1, allowing real time measurements of its optical density.
Ekoanalys-modell : En förenklad modell för att kunna belysa miljöpåverkan redan i designstadiet av en produkt
The environmental debate is more intensive than ever before and the demands on companies increase. There are a number of methods to make it easier for the companies to fulfil the demands. Life Cycle Assessment (LCA) end ecodesign are some of the methods that can be used. Syntronic AB has the possibility to reduce the products´ environmental impact in the design phase. Therefore it is important for the company to make it possible to visualize the negative environmental impacts a product can cause in an easy way. It is also important to visualize for there clients if any improvement is possible. The purpose of this thesis is to develop a simplified model.
