Laboratory adjustment to the new regulation on classification, labeling and packaging of substances and mixtures.

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.

Kemikalier på förskolor : En studie om hormonstörande ämnen och medvetenheten hos förskolepersonal

Chemicals in preschools - a study of endocrine disrupting chemicals and awareness among preschool teachers The purpose of this study was to investigate endocrine disrupting chemicals that have been shown in preschools and also the preschool teachers? awareness of these chemicals. There were two methods used for completing this study; a literature study and a practical study. The literature study was made by researching on the internet and in books. The practical study was performed by sending questionnaires to all preschools in Kiruna municipality to study awareness among staff.

Miljökemikaliers påverkan på isbjörnars (Ursus maritimus) reproduktion och hur dessa kemikalier når djuren

Environmental chemicals are transported to the Arctic through the air and oceans, once within the Arctic they spread through rivers, lakes and other watercourses. Polar bears and sledge dogs in-gest high concentrations of environmental chemicals since many of the chemicals are fat-soluble and their diet mainly consists of marine mammals. The aim of this study is to describe how environmental chemicals spread in nature, how they reach the polar bears, and finally how they affect the animals reproduction, with reproductive hormones and genitals in focus. The animals are exposed to a cocktail effect which complicates the assessment of the chemicals impact on the reproduction. Studies show that the genitals can decrease in size or become malformed, sexual maturation can be affected and the reproductive hormones can be disturbed.

FASTIGHETSPAKETERING : Alltid ett godkänt förfarande?

Chemicals are everywhere in todays society, in humans, animals as well as nature, and they are difficult to avoid. The chemical industry is regarded to be the fastest growing industrial sector, accounting for ten percent of the global economy. A large amount of chemicals are used to produce hygiene products and cosmetics, products that in Sweden only are consumed in quantities of 110 tons per day. Researchers find it increasingly difficult to determine which chemicals that are dangerous and which that are safe, and how they might affect us in the long run. Correlations have been found between chemicals, diseases and other health effects such as cancer, allergies, reproductive and endocrine disorders.

Utfasning av farliga kemikalier - Vid Banverket och Vägverket

Large quantities of chemicals are used in all areas of society. The chemicals can be toxic and dangerous for the environment if used incorrectly. To protect people and the environment from dangerous chemicals, a good control of them and an active work to phase out hazardous substances in all areas where chemicals are present, are needed. Banverket and Vägverket handle in production a wide range of chemical products. Many of the products are dangerous to the environment, for those who work with them and to others who may come into contact with them.

Miljöfarliga transporter till sjöss : Kartläggning och riskanalys

An increasing number of chemicals are being transported by ships along the Swedish coastline. Many of these chemicals may pose a threat to the environment. Accidents and spills are luckily rare, but nonetheless it is important to be prepared for a possible chemical spill. The Swedish Coast Guard is responsible for responding to chemical spills at sea, and has both equipment and trained personnel for the purpose. In order to prepare for a possible accident one also needs to know what is currently being transported at sea.

Gemensamma åtgärder i harmoni? : En beskrivande fallstudie av regional miljöpolitisk koordination mellan nationell och internationell nivå.

 The aim and scope of this study is to describe the coordination of joint efforts concerning chemicals and hazardous substances in the Baltic Sea region, between the Swedish Chemicals Agency (KemI) and the land-based pollution group of the Helsinki Commission (HELCOM LAND). Based on the description of the coordination, the second aim is to discuss the consequences for the Swedish Chemicals Agency in its policy shaping work towards a nontoxic environment. A qualitative and descriptive case study method is used for this purpose. Theories of coordination and achievement-inducing criteria for environmental goals are applied to the case. Components and related processes of coordination are applied to the descriptive part of the study, whilst the achievement-inducing criteria are applied in the discussion.

Metodutveckling för analys av klorfenoler i jord samt analys av förorenad jord från ett sågverk

In this final thesis, an existing method for analysis of chlorophenols (CP) in bottom sediments has been updated and adjusted for analysis of chlorophenols in soil. The covalent bonds between the chlorophenols and the soil matrix were broken through basic hydrolysis and the chlorophenols were then separated from the water phase through addition of sulphuric acid followed by ether extraction. The chromatography was improved through extractive acetylation of the chlorophenols.The updated method was then applied on soil samples from a contaminated area (a former sawmill in Hyttsjö, Östergötland, Sweden).The analyse was preformed by GC/MS with respect to 2-MonoCP, 4-MonoCP, 2,4-DiCP, 2,6-DiCP, 2,4,6-TriCP, 2,3,4,6-TetraCP and pentachlorophenol (PCP).Contamination of chlorophenols in nature can be explained by the former use of wood preservative chemicals based on chlorophenols. In the 1960s and the 1970s these chemicals were used in Sweden, but due to their toxicity they were banned by the Swedish government in 1978.In Hyttsjö a pentachlorophenol-based product named Santobrite was used for several years. The concentration of PCP in the soil samples from Hyttsjö varied from 0.2->1.8 ng/mg dry substance.

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.

Hur används intranät? En studie av EkaForum, Eka Chemicals intranät.

Intranets has been marketing as the tool for solving the organisations information problems. My interest is to see how an intranet works in an organisation. This study was an investigation about the use of EkaForum, the intranet of Eka Chemicals, at the Rollsbo division. The study aimed to evaluate how EkaForum is being used, firstly as a transmitter of information and secondly as a communication tool for the organisation. The study was constructed as a quantity survey based on a questionnaire with 24 questions and was sent out to the staff of Rollsbo division.
