In November 2012, the Australian Pesticide and Veterinary Medicines Authority (APVMA) concluded a 12 year review of the PSII herbicide diuron. One of the primary concerns raised during the review was the potential impact on aquatic ecosystems, particularly in the catchments draining to the Great Barrier Reef. The environmental risk assessment process used by the APVMA utilised a runoff risk model developed and validated under European farming conditions. However, the farming conditions in the sugarcane regions of the Great Barrier Reef catchments have environmental parameters beyond the currently validated bounds of the model. The use of the model to assess environmental risk in these regions is therefore highly inappropriate, demonstrating the pitfalls of a one size fits all approach.
2012 年 11 月，澳大利亚农药和兽药管理局（APVMA）结束了对 PSII 除草剂敌草隆的 12 年审查。审查期间提出的主要问题之一是敌草隆对水生生态系统的潜在影响，特别是对大堡礁流域的影响。APVMA 使用的环境风险评估过程利用了在欧洲农业条件下开发和验证的径流风险模型。然而，大堡礁流域甘蔗种植区的农业条件具有超出模型当前验证范围的环境参数。因此，在这些地区使用该模型来评估环境风险是非常不适当的，这表明了一刀切方法的缺陷。
