This thesis shows how the microscopic particle called microfiber is polluting the oceans. Microfiber generated from synthetic fiber in the process of laundering and its concentration in ocean water are the main themes of this thesis.. The main goal of this thesis is to better understand the cause and consequences of microfiber pollution in the aquatic ecosystem and the way to minimize the quantity of microfi-ber.
In this thesis, experiment was done by using vacuum filtration. The new and old jacket, each 100% polyester, was washed in a washing machine keeping the tem-perature at 40°C. The effluent water released from the laundry was collected for the experiment. The sample was collected in three different phases and was exper-imented with separately. The residues collected after the vacuum filtration were weighed and viewed under the microscope.
The experiment was able to find the mass of the microfiber collected in each phase for the new and the old jacket. The nature and the characteristics of the microfiber were observed. The quantity of the microfibers present in the new and the old jack-et separately was calculated.
The microfiber not only affects the environment negatively but also plays an im-portant role in our lives. Microfibers is used in various everyday products from gar-ments to cleaning products. This thesis describes the ways to minimize the quantity of microfiber. This thesis aims to increase the awareness of the negative impacts of using microfiber releasing products and significant use of the seafood.
