Experiment was conducted in three segments, at first soil  temperature at 10 cm depth in the beach and ambient temperature were recorded, secondly  experiment trial was arranged using the beach sand collected from same beach and thirdly  desk study was conducted to study the impacts of microplastic pollution in the process of  temperature sex determination in turtles during the egg hatching. Soils are a major  component of every ecosystem and most of them are under the threat of pollution. Soil  contamination with MP and potential impact on soil microorganisms and their function is  increasingly recorded from the several parts of the world. MP contamination may be a  significant threat to soil biota if they change their habitat properties. There are several studies  that has done to identify the MP levels in the sandy beaches, but studies on the effects of  such contaminants on the properties which potentially impact the soil biota are lacking. This  study is an attempt to fill this research gap and make primary research base on the discipline. According to the results black colour plastic shows the highest impact on soil temperature  increase compare with the transparent colour and white colour and the increase in soil  temperature also high in the afternoon to night hours where morning hours have indicated  reduction in soil temperature comparative to the control. Even though that the results are not  providing enough statistical evidence to state the level of impact plastic creates on the  parameter of soil temperature, the later three treatments have provided clear tendency of the  temperature alteration. Therefore, the study suggests more in-depth research needs in the  fact, since soil temperature is an important factor which has role play beyond the egg  hatching of turtles to find the magnitude of the ecosystem impact of plastic.           0aMicroplasticsxEnvironmental aspects 0aPlastic marine debrisxEnvironmental aspects 0aMarine pollutionxEnvironmental aspects0 aEkbordin Winijkul,eChairperson 1 aCruz, Simon Gurrero,eExamination committee   0 aTatchai Pussayanavin,eExamination committee 2 aGovernment of Japan,eScholarship Donor2 aAsian Institute of Technology.tResearch studies project report  ;vno.
