A research of 14 toxic affected study sites in Sweden showed a significant increased proportion of deformed diatoms. The six metal polluted study sites in the region of Dalarna showed a 4, 2% average of deformed Fragilaria (deformed diatoms reference sites, 0, 1%). The results also indicate a significant increased proportions of deformed diatoms in the eight pesticide polluted sites in the south and middle of Sweden, compared to the reference sites, howsoever the toxic content was low. The results indicate that there are no lager differences in neither teratological forms nor variations that segregate metal polluted and pesticide polluted shells. One of the reasons may be that both heavy metals and Pesticides can affect the development of the diatom shell..

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of Pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 Pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

The agriculture in Sweden today uses chemical substances to control vermin, weed and diseases. This usage shows through polluted subsoil water and trace elements in the food we eat. There?s a risk that additional symptoms will arise in the future. Our product Sha Jun, developed in 2006-2007, is an attempt to try and minimize the need of chemicals in the agriculture. The idea started with the attempt to minimize the usage of Pesticides on the cropland.

With a changing climate, we can expect higher temperatures and more precipitation in Sweden.As the temperature increases, new weed species are expected to migrate in from more southerlylatitudes, resulting in requests for new techniques for weed control. In addition, we might see agreater number of weed species and higher biomass production due to increased concentrationof CO2 in the atmosphere.Increased understanding of the biology of specific weed species will become more importantin future weed control. This will help to control the weeds more efficiently. Higher prices onPesticides and a public demand for reduced use of Pesticides make growers more inclined to usemechanical weed control on a larger scale and to a greater extent prevent weed establishmentbefore sowing. A well-planned crop rotation is the most important preventive measure, whichmight also include delayed sowing, and dark harrowing and sowing.Research takes place on many levels within the weed area and several alternative methodsare being developed.

In many European countries there is an increasing concern about the occasionally high concentrations of nitrate and Pesticides in drinking water. The advent of the EU Water Framework Directive particularly highlights this. The directive states that all large drinking water sources should be identified and protected from pollution before 2009 and that by 2015 all water bodies should reach a 'good status'. In Sweden about 60 percent of the drinking water sources have protection areas. This means that about 700 new water protection areas need to be designated before 2009. This will affect many farmers, restricting their farming practices. The purpose of this study was to investigate which methods are used in other countries concerning nitrate and pesticide pollution from agriculture. From this, the expectation was to generate ideas on what could be undertaken in Sweden when designating new protection areas.

The population of Grey Partridge is decreasing worldwide as a result of anthropogenic activities. Increased agricultural production, requiring homogenous farming landscapes and increased use of Pesticides are believed to be the main factor causing population declines in the Grey Partridge. Actions to enhance Grey Partridge populations are available; however, those actions are vain if the acceptance to conduct them is low. To gather information about acceptance among farmers, hunters and the County Administrative Board towards 18 available actions enhancing the Grey Partridge population, nine face-to face interviews were conducted as an exploratory case study. The results showed that willingness to conduct enhancing actions differ between and within the groups of stakeholders.

Den biologiska mångfalden är viktig inom lantbruket. Jordbrukslandskapets mångfald är vacker för människan att se på och spännande och rogivande att vistas i. Mångfalden innehåller även en genbank som kan bli mycket etydelsefull i framtiden. Dessutom innebär oftast en rik mångfald bland ogräsen även en rik mångfald bland insekter och andra djur, däribland skadeinsekternas predatorer, vilket bidrar till produktiva åkrar. Ogräsens mångfald på åkern beror till stor del på geografiskt läge, klimat och berggrund.

Abstract.The levels of dioxin and comparable substances rose to a large extent in our environment during the second half of the 20'Th century. This was the result of the synthesis of, and careless usage of these substances in cooling fluids, hydraulics, Pesticides etc. Background levels of dioxins and furans in sealed samples prior to this era suggest that former sources of these substances existed. Salt glazing is a method of adding a smooth acid resistant exterior to stoneware ceramics. The technique has been in use since the 16'Th century, maybe even earlier than that.

In the last years people has become more aware of issues regarding corporate social responsibility. This has led to a more thorough control of big multinational companies, which are often held account of violating social, ethical and environmental values. The term most often used for this is corporate social responsibility (CSR). H&M is a Swedish multinational company and the concept of H&M is fashion to a low price. The material most often used in producing clothes is cotton.

The release of green house gases and the environmental impacts humans have on the environment are huge and might cause irreversible changes to our earth. Meat is considered to have large impacts on the environment, especially beef meat and therefore there have lately been considerable discussions on the sustainable level of meat consumption and production. The main goal with this thesis is to study sustainable meat production and meat consumption in the county of Dalarna in Sweden. Indicators for sustainable meat production and meat consumption were developed and applied on three cases. Interviews were carried out with a municipality in the region that represents the consumer and three beef farmers that represents the producers.
