Experimental system diagram. (IMAGE) Nanjing Institute of Environmental Sciences, MEE Caption Experimental system diagram. Two groups of pre-treatments were performed. The purpose of the first group was to analyze the generation of VOCs from the containers during the irradiation without any solution. The purpose of the second group was to analyze the VOCs from the containers during the irradiation with different solution matrices. Half the volume of the containers was filled with solution. Two groups of irradiation experiments were conducted under the assumption that the bottled water was exposed to sunlight in a place. The first group was solar treatment, while the second group was UV-A-treated experiment. The VOCs were analyzed by SPME and GC-MS.
