1. 1. Micro-by-micro interactions : Aggregation dynamics, biofilms, and ecotoxicological impacts of suspended solids

   Författare :Sophia Reichelt; Elena Gorokhova; Rehab El Shehawy; Julien Gigault; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; suspended solids; microplastics; bacteria; biofilm; aggregation; ecotoxicology; microalgae; Environmental Sciences; miljövetenskap;

   Sammanfattning : Increasing concerns arise regarding the environmental risk of microplastics (MP) and their interactions with biota, prompting numerous effect studies. However, current ecotoxicology methods fall short when it comes to assessing MP impacts. LÄS MER

3. 2. Suspended solids and metals in highway runoff : implications for treatment systems

   Författare :Magnus Hallberg; Gunno Renman; Thomas Pettersson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental engineering; Miljöteknik;

   Sammanfattning : It is known that traffic is a source of pollutants and that pollutant loads increase with elevated traffic densities. Studies executed in Stockholm, Sweden advocate that highway runoff from roads with an annual average daily traffic (AADT) exceeding 30,000 vehicles need treatment before discharge to the receiving water.

4. 3. Suspended solids and indicator bacteria in stormwater runoff : Sources of bias in field measurements

   Författare :Helen Galfi; David Stransky; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Sammanfattning : Stormwater quality monitoring and control is a prerequisite for sustainable water resources management in urban areas. Stormwater monitoring programs are based on general water sampling guidance and, in the absence of standard procedures, employ various sampling and analytical methods. LÄS MER

5. 4. Exploring the ecotoxicity of microparticle debris

   Författare :Zandra Gerdes; Elena Gorokhova; Martin Ogonowski; Tamara Galloway; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microplastics as emerging pollutants; hazard assessment; ecotoxicological experimental design; aquatic toxicology; chemical vector; suspended solids; reference particles; crustaceans as test organisms; behavioural assays in ecotoxicology; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : The global distribution and anticipated increase of environmental microplastic (MP) pollution are concerning. However, while the impacts of macroplastic litter on wildlife are apparent, we know relatively little about the MP hazard potential. LÄS MER

7. 5. Treatment conditions for the removal of contaminants from road runoff

   Författare :Magnus Hallberg; Gunno Renman; Jiri Marsalek; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dissolved matter; filter bed; particulate matter; sedimentation; suspended solids; Environmental engineering; Miljöteknik;

   Sammanfattning : The pollutant load in road runoff is related to traffic densities and road maintenance activities. Inurbanised areas treatment of road runoff is common and often considered necessary. The pollutantsare partitioned between the particulate and dissolved matter. However, the contaminantstend to have an affinity to the particulate material. LÄS MER
