1. Vattenfysikalisk-kemiska och bottenfaunaförhållanden i ett norrländskt vattendrag påverkat av utsläpp från sulfidmalmbrytning och anrikning
Sammanfattning : Gruvbrytnings- och anrikningsverksamheten av komplexa zink-och kopparsulfidmalmer orsakar på flera håll i Västerbottens län vattenföroreningsproblem. För att studera effekterna av utsläppen i recipienten, har undersökningar och utvärderingar gjorts av de fysikalisk-kemiska och biologiska förhållandena i Vormbäcken 1971 - 1975. LÄS MER
2. Oviposition cues as a tool for developing a new malaria control strategy
Sammanfattning : Anopheles gambiae sensu lato mosquitoes are among the dominant malaria vectors in sub-Saharan Africa. However, not much is known about the oviposition behaviour of these species necessary for the development of malaria vector control strategies. LÄS MER
3. In silico methods to prioritize chemicals with high exposure potential
Sammanfattning : Chemicals offer a wide range of desired functions and are used in a variety of consumer goods and industrial sectors. The number of individual synthetic organic chemicals produced and the total global chemical production volume are increasing. LÄS MER
4. Towards better practices in detection of wastewater pollution in stormwater sewers and volume estimation of SSO discharges
Sammanfattning : Separate sewerage systems are designed so that the wastewater and stormwater are carried separately. However, in practice, untreated wastewater discharges to receiving waters are not that rare, impairing the quality of the receiving waters and increasing the risks to public health and aquatic organisms.

5. Characterization, Activation and Reactivity of Natural Pozzolans for Use as Supplementary Cementitious Materials
Sammanfattning : Supplementary cementitious materials (SCMs) represent one of the most practicable ways to reduce the negative environmental impact of cement. Natural pozzolans like clays and volcanic materials (VMs) offer promising alternatives to industrial by-products such as blast furnace slags and fly ashes, whose availability cannot meet the growing demand for SCMs globally.
