Why has it been to difficult to regulate endocrine disruptors?

Regulating endocrine disruptors has been challenging due to the complexity of their effects on human health and the environment, as these substances can interfere with hormonal systems at very low doses and may have long-term, subtle impacts that are difficult to measure. Additionally, the science surrounding endocrine disruption is still evolving, making it difficult to establish clear regulatory guidelines. The diverse range of chemicals involved and their varying mechanisms of action further complicate the development of comprehensive regulations. Finally, economic considerations and lobbying from industries that produce these chemicals often hinder regulatory efforts.
