新污染物聚焦——有机紫外吸收剂-百灵威

有机紫外吸收剂（UVAs）通常被大量添加在化妆品和个人护理用品以及工业产品中，以保护皮肤和高分子材料免受紫外线破坏。UVAs可通过水上娱乐活动、废水处理厂和生活污水排放等方式进入淡水环境，最终通过河流输送进入海洋。

UVAs对植物、动物甚至人体具有潜在的负面影响，POPs公约2023年第八次增列将紫外线吸收剂UV-328列入管控化学物质名单，UVAs已成为对水生态系统构成威胁的新污染物。

UVAs主要分为二苯酮类、二苯甲酰基甲烷类、对氨基苯甲酸酯类、肉桂酸酯类、樟脑衍生类、水杨酸酯类和苯并三唑类等。百灵威可供应以上七类UVAs标准物质及配套分析试剂与耗材。
