Algae blooms, induced by eutrophication, have been an increasingly prevalent environmental concern in the Baltic Sea since the 1970s, causing ecosystem degradation and hypoxia in bottom layers. One predominant harmful algae bloom-forming species in the Baltic Sea is the cyanobacteria Nodularia spumigena. N. spumigena produces hepatotoxin nodularin and is a diazotrophic alga; hence, it should be
This study was conducted on blue mussels, Mytilus edulis trossulus, to investigate how the blue mussels have been affected by the bunker oil following the oil spill from the ferry Marco Polo. The study will examine the impact of bunker oil on the physiology and behavior of the blue mussel. The blue mussel is one of the key species in the Baltic Sea and serves as an indicator species, making it sui
Ensuring food safety is an international goal and the Swedish national authority for food has just implemented a new system for risk-based food control. The new system for analyzing food businesses in a risk-based evaluation is based on EU-directives. The directive aims to use risk factors to evaluate food businesses when municipalities plan food safety inspections. In the former system for risk-b
The aim of this literature study was to review the effects that climate change has on the intensification of eutrophication in lakes, specifically in a temperate climate. Furthermore, the latest research on the connection between greenhouse gas emissions and eutrophication in lakes was reviewed to explore the synergistic relationship between the two processes. In summary, the results were that the
Environmental pollution stems from industrial emissions to the air, soil and water. This has resulted in many areas being contaminated today by, among other things, heavy metals, petroleum hydrocarbons and PAHs. Approximately 86.000 contaminated sites have been identified across Sweden. Identifying contaminated sites enables inventory and risk classification. Therefore, the method for the inventor
Circular public procurement has the potential of supporting the transition towards a circular economy. Public purchases of IT are responsible for a significant amount of Sweden’s total public procurement emissions. However, IT product’s climate impact can also be greatly reduced through circular strategies. With the goal of inspiring and guiding public procurement officers and decision makers to p
Biodiversity-, and ecosystems face the risk of being lost due to human impact through land exploitation, and transport emissions from tourism, but also from the negative impacts of climate change. Öland has several protected areas with its unique landscapes, and high natural values. Which has attracted several visitors to the island. This study presents a comprehensive investigation on which confl
To sustain a good environment, it is crucial for businesses to be aware of the environmental laws and regulations. However, many smaller businesses and actors may struggle to comply with the complex regulations, which can lead to potential environmental harm. The aim of this study is to investigate the handling of hazardous waste by smaller businesses and if they have necessary knowledge about the
A regular consumption of food contaminated with heavy metals can pose a threat to the general health of the human population. The contents of these toxic metals in crops depend on several different factors including the acidity of the soil as well as the addition of contaminated fertilizer. In this study, health risk assessments for broad beans (Vicia faba) were made for six different growing cond
In this thesis work the potential of compost as a sustainable alternative to peat as soil amendment was investigated. Peat extraction has substantial negative environmental impacts, but concerns exist about potential contaminant accumulation in compost. Four soil amendments, one sourced from a Scanian municipality and three commercially available, were analyzed for the presence of 10 metals, 35 PF
Plastics play a central role in our society today and are omnipresent. Compost frommgarden waste is used in gardening as a soil amendment. This circular use of plants, branches and other green waste is a way to reduce the use of linear resources for soil amendment, such as peat. A problem that can arise when using compost is the spread of plastic particles from the garden waste to the environment.
The European Union (EU) aims to increase the overall carbon sink through the 2030 climate and energy policy framework, which includes the newly reviewed instrument and regulation of Land use, land use change and forestry (LULUCF). The regulation is considered an important component in the EU climate mitigation strategy which aims to manage and track the greenhouse gas emissions and removals in sec
This study has been conducted to show the meaning of how background factors and attitudes affect the usage of chemical products in urban gardens in Lund. This was performed with the use of a questionnaire that was sent out to two Facebook groups, Lunds Trädgårdssällskap and another private group oriented towards people who live in or come from Lund. From an environmental perspective, this study is
The sport of disc golf has grown rapidly during the last five years, meaning a rapid increase in production of discs, and therefore also in the use of virgin plastics. The discs are usually produced with thermoplastic polyurethane (TPU) or thermoplastic elastane (TPE). The disc golf market is dominated by a handfull of brands that all have one thing in common, their work on sustainability is eithe
The forest industry has big problems with the bark beetle attacking trees. This results in that they must log the damaged trees, which leads to an economic loss. For a tree to be able to stand against a big populations of bark beetles, it needs to have a strong defence or be surrounded by other trees via associational resistance. Furthermore, natural enemies to the bark beetle can also act as a de
Bioenergy derived from agricultural biomass has potential to phase out fossil energy sources while strengthening the bioeconomy. To estimate the agricultural sector's potential to meet the rising demand for renewable energy sources, it is crucial to understand what motivate farmers to sustainably increasing agricultural feedstock production. Through eight semi-structured interviews, and online
In this study an evaluation of the ways in which the shopping mall NOVA Lund can improve its current waste management practices was conducted. This was done because NOVA plans to upgrade their waste management system. A survey was conducted where the staff of the 68 stores and 7 restaurants were inquired on the current system. The stores were asked to rank what kind of waste they encounter the mos
The growing mountain of electronic waste is a threat to human health and an unsustainable handling of our finite natural resources. With the aim to decrease the creation of waste, including electronic, the EU have decided to separate resource use from economic growth by supporting the transition to a circular economy. The inclusion of the private sector in the financing of this transition is cruci
Clean drinking water is often taken for granted. However, the lake that supplies the greater part of southwestern Scania with drinking water has severe environmental problems regarding the chemical and ecological status. The organization Fokus Vombsjön has now taken it upon themselves to develop a water management plan for the lake, with the goal to improve its overall status. The aim of this s
Today the future supply of seafood is threatened due to human activities which, among other things, has led to overfishing. However, more environmental friendly initiatives of producing seafood have emerged, such as Recirculating Aquaculture Systems (RASs). By analyzing the sensitivity analysis from six different Life Cycle Analysis (LCAs) on RASs, eight different factors that influence the enviro
