In this study the practical work with the EU Water Framework starts on the island of Gotland. 33 lakes and 32 streams have been characterized and classified regarding to their ecological status. The aim with the characterisation is to create a uniform discription of all waterbodies and a comparable estimation for the future. The aim with the classification is both to study the waterbodies ecological status and to gain knowledge of where the resources should be concentrated so that the ecological status in all waterbodies will be good in 2015.The characterisation has been done according to the EU Water Framework Directive, and the factors that have been applied are the mean depth and area of the lake. The length and size on the catchment area are the factors that have been used on streams.

This master thesis was written for Arla Foods and the result of the thesisserves to gain Arla Foods in its work with Chemical hazardous and to bringnew academic results. The thesis aims to create a common methodology forrisk analysis with the handling of Chemicals.The theories displayed in this thesis focuses on different risk managementmethods in order to build up a framework out of which a risk management toolwas created. The main primary data source consists of interviews held withemployees within Arla Foods at different facilities.The risk management tool can be found in appendix K.Available recommendations for how to evaluate risks with Chemicals can befound at appropriate government agencies. These recommendations aredrawn up to suite small and medium enterprises and therefore are to narrowto make a good foundation for analysing Chemical risks at large companies.With the legislation and government demands in mind, a tool has beencreated to fit a large company?s needs when managing Chemical risks.

The aim of this thesis is to investigate the correlation between the price of electric power and investments within the Swedish basic industry. Using regression analysis, the authors test for correlation between the electricity prices and the basic industry, defined as the pulp and paper industry, the mining industry, the steel and metal industry and the basic Chemical industry. Moreover, five variables found in the literature on investment decisions are being used as a means of comparison. The results suggest that the electricity price affects the investment decisions within the basic Chemical industry as well as the steel and metal industry. On a more abstract level, this thesis contributes to the understanding of one of the properties of the Swedish GDP..

Employer Branding är ett begrepp som fått stort genomslag i organisationer världen över. Begreppet innebäratt företag arbetar med sitt arbetsgivarvarumärke i syfte att attrahera, motivera och behålla personal.Ett företag som vill utveckla sitt Employer Brand är Arizona Chemical. Arizona Chemical ligger i den lillabruksorten Sandarne strax söder om Söderhamn. Arizona Chemical har gett mig i uppdrag att ge konkretaråd på Employer Branding strategier utifrån företagets förutsättningar. Genom intervjuer med anställda harjag kartlagt organisationens problembild och belyst de behov som finns av en Employer Branding strategi.För att kunna förankra mina förslag på strategier i teori har jag gjort en forskningsöversikt över fenomenetEmployer Branding.

BACKGROUND & During the last century, the Swedish Chemical industry has developedPROBLEM: considerably in regard to respecting the environment. Following various discharges and pollutions during the first half of the 20th century, environmental concepts such as CSR, Responsible Care and REACH have developed in order to improve the situation. Today, environmental issues play a central role in the society, but what are the reasons behind this increased environmental commitment? PURPOSE & The purpose of this thesis paper is to study the driving forces behindDELIMITATIONS: the increased environmental awareness in companies. Is this mainly due to stricter legislations, or do factors like pressure from the general public, the industry or customers play a more vital role? Furthermore, do economic incentives exist, that make it interesting for companies to invest in environmental awareness? Since the Chemical industry spans over a wide spectrum in regard to environmental issues, this paper will focus on a specific area of the industry.

Landfill leachate contains a variety of contaminants and is created when rainwater percolates the landfill. For landfill management the leachate is the main issue that can cause problems to the environment. At the landfill of Fläskebo, Renova AB treats the leachate in a local treatment plant. The treatment consists of a Chemical treatment step with Chemical precipitation, flocculation, sedimentation and filtration, and a final step with a carbon and peat filter. Renova has to ensure that the condition of the leachate reaches the regulation set for the landfill before it is released to the recipient.

Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and Chemical analysis were used.

The United Nations has, during many years, developed a model for a globally harmonized system for classification and labeling of Chemicals, with the aim of it becoming a global standard. This system is implemented in the European Union through the CLP-regulation and is now working parallel to the existing directives until 1st of June 2015, when all the new classifications of substances and mixtures must be completed. The aim of this project was to adjust the laboratory to the new legislation, through inventory of stored Chemicals, update the list of Chemicals and perform self-classifications of mixtures. The work included handling of about 650 different Chemicals with varying hazard classifications and search for information in corporate websites and Chemical databases. This resulted in a new and complete list of Chemicals stored and used in the laboratory and, in addition, an example of how to make a self classification of a mixture.

Nanotechnology, one of the most interesting sciences today will no doubt have an enourmous impact on tomorrow's society and industry. One of the most interesting nanomaterial that has been discovered is the semiconductor quantum dot (QD). This material shows interesting novel properties such as a size-dependent band gap, which is an effect caused by the quantum confinement effect in all three dimensions. Due to this phenomenon the absorption spectrum can be tuned to the desired value by adjusting the size of the QD.This thesis aims to investigate how the solvent ratio of H2O/Ethanol affects the optical and structural properties of copper sulfide QDs manufactured in a Chemical synthesis way using modern microwave heating. The process of manufacturing QDs using Chemical synthesis often involve a capping-agent to prevent the QDs from agglomerate into bigger structures.

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW Chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.
