Abstract

The majority of bottled water industry uses polyethylene terephthalate (PET) bottles as their packaging. When exposed to direct sunlight, this type of packaging is able to cause new compounds in water. Research at the State University of New York states showed that from 259 bottled water in 9 countries, 242 of them contained microplastics. The purpose of this study is to determine whether there are differences in the amount of microplastic in bottled PET containers that are exposed and not exposed to sunlight. This type of research is pre-experimental using the static group comparison design. There are 2 treatment groups: PET bottled water that is exposed and not exposed to sunlight. The results showed that there were microplastics in PET bottled water exposed and not exposed to sunlight. Samples of bottled PET which exposed to sunlight have microplastic’s number of 175 particles/ liter. Whereas bottled water that was not exposed to sunlight has microplastic’s number of 132,25 particles/ liter. Independent t-test showed that the Sig (2-tailed) value was 0,023. This value less than = 0,05. So, we can say that there were differences between both of them. The conclusion of the study was that there were differences in the number of microplastics between PET bottled water exposed and not exposed to sunlight. As a form of vigilance, the public is advised to deliver PET bottled water from direct sunlight both for distribution and other type utilization of PET bottles for other purposes such as disinfection of water using sunlight (SODIS).

Highlights

Bottled Drinking Water (AMDK) is water that has been processed, without other foodstuffs and food additives, packaged, safely for drinking (Regulation of The Industrial Ministry Number. 96 at 2011)
Shandytias (2018) stated that there were 10 chemical compounds missing and 4 chemical compounds that were detected recently in sample water exposed to direct sunlight in a Polyethylene Thephthalate (PET) bottle
The results showed that the average number of microplastics in bottled drinking water samples was 101 particles / liter

Summary

Introduction

Bottled Drinking Water (AMDK) is water that has been processed, without other foodstuffs and food additives, packaged, safely for drinking (Regulation of The Industrial Ministry Number. 96 at 2011). Shandytias (2018) stated that there were 10 chemical compounds missing and 4 chemical compounds that were detected recently in sample water exposed to direct sunlight in a Polyethylene Thephthalate (PET) bottle. The organization states that the level of microplastics in drinking water is not yet so harmful to human health at present. This is based on his research on the impact of exposure to microplastics in tap and bottled water. A polymer that is exposed to sunlight can undergo photochemical aging, including in the case of the PET plastic type. No. this bottled water can be deliberately or not exposed to direct sunlight This has the risk of creating more microplastics than before. The analysis method in this way can provide information about the shape and color of microplastics (Agnes Veronica V., 2017)
