IDENTIFICATION OF MICROPLASTIC CONTENT IN REFILLED DRINKING WATER IN THE DISTRICT OF GUNUNG ANYAR SURABAYA, INDONESIAFIRRA ROSARIAWARI, MUHAMMAD NASHRUDDIN ABDULLOH AND NURINA FITRIANIAbstract The need for drinking water is increasing, especially in urban areas. To meet the drinking water needs, people use refilled drinking water as the main alternative because the price of bottled drinking water is relatively expensive. In bottled drinking water, it is known that it contains microplastics which can harm human health, while no research has been conducted to determine the microplastic content in refilled drinking water. Therefore, research is needed to determine the microplastic content in refilled drinking water and its causes. In this study, 25 refill drinking water samples were used using the Fourier Transform Infra Red (FTIR) analysis method to determine the types of microplastics and manual calculation methods to determine the number of microplastics. From the research results, it was found that all samples contained microplastic, according to their type, it was found that 25 samples contained HDPE type microplastics, |
