1. 1. Automation of carbonyl index calculations for fast evaluation of microplastics degradation

   University essay from KTH/Fysik

   Author : Maja Walfridson; Emma Kuttainen Thyni; [2022]
   Keywords : FTIR; Carbonyl index; Degradation of microplastics; Microplastics; Automation;

   Abstract : The broad use of plastics has resulted in the increase in both production and consequent plastic pollution in the environment. Microplastics, defined as particles < 5 mm, is of special interest because of its wide existence in environment and potential hazards to our ecosystem. READ MORE

3. 2. Microplastics In Ringed Seals From The Baltic Sea - Method development regarding the detection of microplastics in the digestive tract contents of marine mammals

   University essay from Lunds universitet/Examensarbeten i biologi

   Author : Nicola Parfitt; [2021]
   Keywords : Biology and Life Sciences;

   Abstract : Plastic pollution is a severe global problem and every year approximately 368 million tons of plastic is produced. Both terrestrial and marine environments are impacted and hundreds of species affected. READ MORE

4. 3. Enhancing the degradation rate of microplastics and organizing a study visit about sustainability

   University essay from KTH/Lärande

   Author : Marianne Al-Ghorabi; [2020]
   Keywords : Accommodation; assimilation; Fenton reaction; microplastics; polypropylene; polystyrene; proximal development zone; study visit; visible light photocatalysis; zinc oxide nanorods; Ackommodation; assimilation; den proximala utvecklingszonen; Fenton reaktion; fotokatalys med synligt ljus; mikroplast; polypropalen; polystyren; studiebesök; zinkoxid nanorör.;

   Abstract : Microplastics take hundreds to thousands of years to degrade in nature, and pose a threat to the environment. A photocatalytical degradation method have been developed to take advantage of solar light to degrade microplastics, however it takes several months to degrade microplastics with the process.

5. 4. Photodegradation of macroplastics to microplastics : A laboratory study on common litter found in urban areas

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Jonathan Svedin; [2020]
   Keywords : ;

   Abstract : During the last 60 years the plastic production has increased more than 190 times and plasticpollution both at sea and land is a growing issue. Every year millions of tons of plastic waste fromland reaches the oceans, but the land-based sources are diffuse. READ MORE

6. 5. Degradation of Microplastic Residuals in Water by Visible Light Photocatalysis

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Tajkia Syeed Tofa; [2018]
   Keywords : Microplastics; Low density Polyethylene LDPE ; Heterogeneous photocatalytic degradation; Zinc oxide nanorods; Visible light.;

   Abstract : Microplastic (MP) pollution has recently been recognized as a threat to the biosphere including humans due to its widespread distribution, persistent nature and infinitesimal size. This study focused on the solid phase degradation of microplastic residues (particularly low density polyethylene, LDPE) in water through heterogeneous photocatalysis process by designed photocatalysts of zinc oxide nanorods (ZnO NRs) and platinum nanoparticles deposited on zincoxide nanorods (Pt NPs-ZnO NRs) under visible light irradiation.
