ISO 3890-2:2009标准是针对牛奶及其制品中有机氯农药残留的检测方法。有机氯农药是一种广泛使用的农药，但它们具有高毒性和长期残留的特点，对人体健康和环境造成潜在危害。因此，对牛奶及其制品中有机氯农药残留的检测非常重要。

本标准规定了提取纯化和确认测试方法，以确保检测结果的准确性和可靠性。提取纯化方法包括样品制备、提取、分离和纯化等步骤。确认测试方法包括气相色谱-质谱联用（GC-MS）和气相色谱-电子捕获检测器（GC-ECD）等方法。这些方法可以有效地检测牛奶及其制品中有机氯农药残留的含量。

本标准适用于牛奶及其制品中有机氯农药残留的检测。在实际应用中，可以根据需要进行适当的修改和调整，以满足特定的检测要求。

ISO 3890-2:2009标准的实施可以有效地保护人类健康和环境，防止有机氯农药残留对人体和环境造成潜在危害。因此，该标准在食品安全和环境保护方面具有重要意义。
