Acidification in lakes has a large impact on ecosystems. A new study of Swedish lakes shows that, as a result of international reductions of acidifying, water quality has improved but the biological recovery is still lagging.
Eggs collected from seabirds from several islands in the Norwegian Sea contain large numbers of toxins. In a new study the researchers found 158 different substances in the collected eggs. Particularly troubling is the discovery of new substances; some which of have been meant as a better alternative to now-banned substances.
The current dietary recommendations for the consumption of fatty fish from the Baltic Sea limit the opportunities for sales, mainly of salmon and herring. IVL Swedish Environmental Research Institute has now, along with coastal fishermen from the northern counties of Sweden, launched a project that aims to optimize both fishing and its processing so that the amount of dioxins in fish is minimized.
As the supply and use of ore-based steel will decrease in the future it will be more important that the quality of recycled scrap metal maintains as high as possible. By following the global scrap flows, one can see which materials are of sufficient quality and which are not.
IVL Swedish Environmental Research Institute has developed a new hybrid-LCA tool that combines conventional LCA with input/output models. The result is a life cycle analysis that comes closer to the truth, makingIVL a forerunner in LCA methodology.
How can we measure the improvements in waste management? Are there development differences between different municipalities and what conclusions can we, if so, deduct from it? IVL Swedish Environmental Research Institute has together with the consulting firm Profu developed specific indicators for this purpose.
Freight transports comes with a number of undesirable effects, on the environment and health as well as loss of time due to traffic congestions. These effects can be measured by using the concept of external costs; costs paid by other than the goods owners or the carriers - generally by society at large.
The full effects of our consumption on the environment and natural resource depletion are poorly understood. To safeguard both the economy and environment the European Union is aiming to improve resource efficiency. As part of this process, IVL researchers will provide the European Commission with datasets of life cycle assessments to help model the environmental effects of EU trade – both imports and exports.
Since the 60's, the rainfall over south western Sweden and the Gothenburg area has almost doubled and by 2100 it is expected to increase by a further thirty percent. More rain leads to both elevated groundwater levels and surface runoff, effects which ultimately will increase the risk of contaminated drinking water.
A comparative analysis done by IVL Swedish Environmental Research Institute shows that from a health and environmental perspective emissions from ethanol cars are only slightly better than those fuelled by petrol.
