Kan inställningen till framtida sexualvanor och deltagande i gynekologisk cellprovskontroll påverkas av HPV-vaccinering? : En kvalitativ innehållsanalys.

Human Papilloma virus (HPV) can lead to cervical cancer, a common form of cancer in Sweden and globally. A vaccine has been developed for the most Carcinogenic strains of HPV. In Sweden it is planned that the vaccine be included in the public national vaccination program for children. The aim of this study was to illustrate attitudes towards future sexual habits and preventive cervical cancer screening among young women and parents of girls vaccinated against HPV. This study is a part of a larger project where interviews with young women aged 17 to 26 years and parents of girls aged 13 to 17 years compose the foundation.

LCA av dricksvattendesinfektion : en jämförelse av klor och UV-ljus

Disinfection methods for drinking-water produced at the two water works of Stockholm Water Co are compared in this study. Three different nethods are compared; disinfection with chlorine gas, disinfection with sodium hypochlorite and disinfection with UV-light and monochloramine. The method used is Life cycle assessment, LCA. LCA is defined as the compilation and evaluation of the inputs, outputs and potential environmental impact of a product system shroughout its life cycle. The environmental burden is compared for the three different disinfection methods.

Kartläggning av föroreningars förekomst och spridning i Gräsötippen enligt MIFO

It is estimated that 22 000 contaminated areas exist in Sweden today. In order to classify the risk of contaminant migration from these areas and to prioritize which of these contaminated areas should first be treated, the Swedish Environmental Protection Agency (EPA) has designed a method, for the investigation of contaminated areas (MIFO). One of these contaminated areas is the landfill Gräsötippen outside Köping. The landfill has been used by both Yara AB and the Köping municipality between the years 1945 and 1975, and both industrial and household waste have been deposited there. The aim of this report is to survey which contaminants that can be found in the soil and water in the landfill Gräsötippen and to evaluate the migration of these contaminants.

Geografiska informationssystem för studier av polyaromatiska kolväten (PAH) : undersökning av djupvariation i BO01-området, Västra hamnen, Malmö, samt utveckling av en matematisk formel för beräkning av PAH-koncentrationer från ett kontinuerligt utsläpp

At the end of August 1999, the local government council of Malmö city decided thatthe area known as Kvarteret Bilen would be made available for the European HousingExhibition 2001 (Bo01-mässan). Kvarteret Bilen extends over approximately 80hectars and includes the western parts of the Western Harbour area (Västra hamnen)of Malmö.Kvarteret Bilen as a whole, but especially the western sections of this area, the socalledBo01 section, has been the subject of heated discussions. This is mainly due tothe fact that the ground in question has proven to be contaminated to a certain extentby different chemical compounds. Investigations undertaken during 1998 showed sporadically high concentrations forespecially one chemical group: polycyclic aromatic hydrocarbons (PAH).The first part of the paper describes the use of a mathematical equation (Fetter 1994)to calculate the concentration of PAH from a continuous discharge at a given time byemploying Geographical Information System (GIS). Even the constraints of theequation are discussed, as well as the consequences that follow as a result of usingGIS.The second part of the paper focuses on the connections between the content ofCarcinogenic PAH in Kvarteret Bilen and the ground water level and type of fillingmaterial.

Fumonisin B1 : toxiska effekter och verkningsmekanismer för toxicitet

Mykotoxinet fumonisin B1 som förekommer i hela världen på framförallt majs, har visats ge upphov till flera olika toxiska effekter hos en mängd olika djurslag. De mest specifika är leukoencefalomalaci hos häst (ELEM) och lungödem hos gris (PPE), men även skador i lever, njurar och hjärt-kärlsystemet samt Carcinogenicitet har observerats. Effekterna skiljer sig en hel del mellan olika djurslag, vilket den här uppsatsen syftade att hitta möjliga anledningar till. Dessutom var syftet att sammanställa information om fumonisins verkningsmekanismer ? både bekräftade och mer osäkra sådana, samt beskriva de toxiska effekterna hos olika djur och i olika organ och även ta upp diagnosticering, vilken dos som krävs för att orsaka sjukdom samt jämföra de rekommenderade gränsvärden som har satts upp för fumonisiner i foder med forskningsresultat.

Naturlig förekomst av arsenik och avskiljning av arsenik från grundvatten : test av olika filtertekniker avsedda för enskilda brunnar

During the last few years the presence of high arsenic (As) concentrations in ground water has been of major concern both internationally and in Sweden. Much evidence has been reported about toxic effects caused by arsenic. The Carcinogenic effects and the possibility to measure the toxic impacts at low concentrations made the World Health Organisation (WHO) to reduce the guideline value from 50 to 10 ?g l-1 in 1993. In Sweden the corresponding reduction was implemented in 2003. Several surveys in Sweden have shown that high arsenic concentrations may occur in ground water.
