  3. 17. The Impact of Polystyrene Microplastics on Filtration Rate in the Marine Copepod Acartia tonsa

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Len-Oliver Ottvall; [2016]
    Keywords : Biology and Life Sciences;

    Abstract : Microplastic particles are of increasing environmental concern around the globe and recent studies have shown that these particles are present in the entire water column, thus affecting a range of zooplankton including copepods that have a vital role in the marine food web. This study investigated whether microplastic beads have an effect in the filtration rate in the copepod Acartia tonsa, which was collected outside of Ålabodarna located in Oresund. READ MORE

  4. 18. Assessment of numerical integration schemes and boundary conditions for Lagrangian tracking of marine debris

    University essay from Lunds universitet/Matematik LTH

    Author : Joel Kronborg; [2016]
    Keywords : Lagrangian tracking; PARCELS; Runge-Kutta; time stepping; boundary conditions; Mathematics and Statistics;

    Abstract : A growing environmental issue today is the amount plastic pollution in the ocean. To investigate how it might affect marine life, an important aspect is to study how plastics are transported by ocean currents and where it ends up. This can be done by use of Lagrangian simulation of plastic particles in computer ocean models. READ MORE

  5. 19. The Journey of Plastic trough Oceans : A study on quantifying micro plastic particles in ocean outside Costa Rican west coast

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Frida Roos Lundström; Anna Mårtensson; [2015]
    Keywords : plastic marine pollutions; micro plastic particles; marine debris; marine litter; plastic production;

    Abstract : Since 1950, the plastic production has increased radically from 1.5 to 280 million tons in 2012. The increased production of plastic has led to oceans becoming more polluted than ever. Micro plastic particles originate from large floating plastic debris by undergoing degradation caused by UV-radiation. READ MORE

  6. 20. Plastic as marine debris and its potential for economic value : A practical and analytical estimation of the marine debris characteristics and a comparative evaluation of possible treatment procedures

    University essay from KTH/Industriell ekologi

    Author : Astrid Hartman; Ella Lovén; [2014]
    Keywords : ;

    Abstract : Every year around 270 million tonnes of plastic are produced worldwide. As a result of poor waste management in many countries, a large amount of it ends up in the world’s oceans where it degrades into micro particles. READ MORE
