After directly analyzing the commercially available water samples, 3 polymer additives (chimassorb 81, irgafos 168 and oleamide) were detected. However, after exposure to sunshine for 8 days, two additional polymer additives (antioxidant 2246 and Butylated Hydroxytoluene (BHT)) were detected besides the former three additives.展开更多
