Endocrine disruptors (EDs) disrupt the standard operation of the endocrine systems, resulting in untoward effects. EDs have gained extensive consideration due to their severe adverse impacts on public and wildlife health. A variety of compounds from both natural and synthetic origin may cause endocrine disruptions. These may be found in industrial chemicals, persistent organic pollutants, and products of regular use including pharmaceuticals, medical equipment, implants, medical/surgical and dental devices, cosmetics, food products, other consumer goods, their packaging and processing materials. Apart from direct consumption or use, these chemicals may impact by entering our food chain or ecosystem. These chemicals act by mimicking the hormones or blocking their receptors or interfering in their normal production, absorption, distribution, metabolism and excretion. The implementation of a regulatory framework on the complex multidisciplinary field of EDs brings enormous challenges, which pose barriers to the regulatory process. This study aims to focus on the key public and ecological health concerns presented by EDs, challenges faced by regulators to achieve successful regulatory proposition and the importance of collaboration endeavours to potentially conquer such challenges. Endocrine-disrupting chemicals (EDCs) or EDs can impact at low exposure levels, bringing about a broad range of health issues including disorders related to reproductive, fetal development, neurological, immunological, metabolic and cancer, etc. They may cause health effects across generations. The regulatory frameworks available across major regulators are tackling the identification of EDs and their mechanisms to provide necessary guidance on the safety and disposal of such substances. However, the challenges faced outweigh the regulatory mechanisms in place. The major challenges are related to structural ranges at times leading to no representative structures, active metabolites, substantiate quantum, delayed effects, epigenetic changes, widespread existence, concentration correlation for different biological species, availability of appropriate methods, exposure to a mixture of chemicals, complex endocrinology principles, unknown sources, routes and mechanisms, impacts at early stages of life, geographical movement of EDs, hazard-based vs. risk-based approaches. Regulators of healthcare and environmentalists needs to collaborate amongst them and with wider stakeholders including industry sponsors to find ways of dealing with such challenges and capitalize on the research-based knowledge grid available across institutions. Existence of EDs, their impact on living beings and mechanism of influence are like a tangled web, which induces difficulties in regulating them with conventional mindset. Conquering these challenges necessitates that regulators should join forces amongst themselves, with other institutions operating for environment, with industry sponsors and researchers to achieve success in public health safety.
内分泌干扰物(EDs)会扰乱内分泌系统的正常运作,从而产生不良影响。由于其对公众和野生动物健康造成的严重不利影响,EDs已受到广泛关注。天然和合成来源的多种化合物都可能导致内分泌干扰。它们可能存在于工业化学品、持久性有机污染物以及日常用品中,包括药品、医疗设备、植入物、医疗/外科和牙科器械、化妆品、食品、其他消费品及其包装和加工材料。除了直接消费或使用外,这些化学物质还可能通过进入我们的食物链或生态系统产生影响。这些化学物质通过模仿激素、阻断其受体或干扰其正常的产生吸收、分布、代谢和排泄来发挥作用。在EDs这个复杂的多学科领域实施监管框架带来了巨大挑战,这些挑战对监管进程构成了障碍。本研究旨在关注EDs引发的关键公共和生态健康问题、监管机构在实现成功监管提议时面临的挑战以及合作努力对于潜在克服此类挑战的重要性。内分泌干扰化学物质(EDCs)或EDs在低暴露水平下就可能产生影响,引发一系列广泛的健康问题,包括与生殖、胎儿发育、神经、免疫、代谢和癌症等相关的疾病。它们可能会对多代人造成健康影响。各大监管机构现有的监管框架正在应对EDs的识别及其作用机制,以便为这类物质的安全性和处置提供必要指导。然而,面临的挑战超过了现有的监管机制。主要挑战包括结构范围有时导致没有代表性结构、活性代谢物、确凿的量、延迟效应、表观遗传变化、广泛存在、不同生物物种的浓度相关性、合适方法的可用性、接触化学物质混合物、复杂的内分泌学原理、未知来源、途径和机制、生命早期阶段的影响、EDs的地理移动、基于危害与基于风险的方法等。医疗保健监管机构和环保主义者需要相互协作,并与包括行业赞助商在内的更广泛利益相关者合作,以找到应对此类挑战的方法,并利用各机构现有的基于研究的知识网络。EDs的存在、它们对生物的影响及其影响机制就像一张错综复杂的网,用传统思维来监管它们会引发困难。克服这些挑战需要监管机构相互联合,与其他从事环境保护的机构、行业赞助商和研究人员共同努力,以实现公共卫生安全方面的成功。
