Influence of Sunlight on Drinking Water in Packaging in Plastic Type of Polyethylene Terephtalate Related to Antimon Content

Abstract

Water is an important substance in life. Increased population causes increased demand for quality drinking water. Existence of safe drinking water is urgently needed. The acquisition of sun exposure data on botteld water can cause the release of chemicals that are toxic to the water that one of them is very interesting antimony to be studied. Antimony is a contaminant of drinking water that can cause acute effects and chronic effects. The purpose of this study was to determine the amount of antimony that migrated into bottled water after exposure to sunlight after 8 hours of exposure. The study included "Pre-Post Test Control Group Design". The sampling metode was simple random sampling. The data obtained were tested using anova test. Anova test results showed a significant difference after treatment. The antimony level increased 2.17 times after treatment in the sample group and 1.41 times in the control group. This is indicated that exposure to sunlight had more antimony levels contained in drinking water that’s why storage of bottled drinking water at high temperatures is not recommended. The test results also show that there is a significant difference in storage time.
