The regulatory assessment of endocrine disrupting chemicals (EDCs) is complex due to the lack of a standardized definition of EDCs and validated testing criteria. In spite of these challenges, there is growing scientific interest in EDCs which has resulted in the rapid expansion of published literature on endocrine disruption upon chemical exposure. Here, we explore how academic research leading to curated knowledgebases can inform current chemical regulations on EDCs. To this end, we present an updated knowledgebase, DEDuCT 2.0, containing 792 potential EDCs with supporting evidence from 2218 research articles. Thereafter, we study the distribution of potential EDCs across several chemical lists that reflect guidelines for use or regulations. Further, to understand the scale of possible exposure to the potential EDCs present in chemical lists, we compare them with high production volume chemicals. Notably, we find many potential EDCs are in use across various product categories such as ‘Food additives and Food contact materials’ and ‘Cosmetics and household products’. Several of these EDCs are also produced or manufactured in high volume across the world. Lastly, we illustrate using an example how diverse information in curated knowledgebases such as DEDuCT 2.0 can be helpful in the risk assessment of EDCs. In sum, we highlight the need to bridge the gap between academic and regulatory aspects of chemical safety, as a step towards the better management of environment and health hazards such as EDCs.

使用公共资源从内分泌破坏化学品的角度对当前化学品法规和指南进行探索性分析

由于缺乏EDC的标准化定义和经过验证的测试标准,内分泌干扰化学物质(EDC)的监管评估非常复杂。尽管存在这些挑战,但对EDC的科学兴趣日益增长,这导致有关化学暴露引起的内分泌干扰的已发表文献的迅速增加。在这里,我们探索导致策展知识库的学术研究如何为EDC的当前化学法规提供信息。为此,我们提出了一个更新的知识库DEDuCT 2.0,其中包含792个潜在的EDC,并提供了2218篇研究文章的支持证据。此后,我们研究了反映出使用指南或法规的几种化学物质清单中潜在EDC的分布。此外,要了解可能与化学品清单中存在的潜在EDC接触的规模,我们将它们与高产量化学品进行了比较。值得注意的是,我们发现许多潜在的EDC正在各种产品类别中使用,例如“食品添加剂和食品接触材料”以及“化妆品和家用产品”。这些EDC中的一些也在世界范围内大量生产或制造。最后,我们通过一个示例说明了精选的知识库(如DEDuCT 2.0)中的各种信息如何有助于EDC的风险评估。总而言之,我们强调需要弥合化学安全性在学术和法规方面之间的差距,以迈向更好地管理环境和健康危害(例如EDC)的一步。我们发现,许多潜在的EDC正在各种产品类别中使用,例如“食品添加剂和食品接触材料”以及“化妆品和家用产品”。这些EDC中的一些也在世界范围内大量生产或制造。最后,我们通过一个示例说明了精选的知识库(如DEDuCT 2.0)中的各种信息如何有助于EDC的风险评估。总而言之,我们强调需要弥合化学安全性在学术和法规方面之间的差距,以迈向更好地管理环境和健康危害(例如EDC)的一步。我们发现,许多潜在的EDC正在各种产品类别中使用,例如“食品添加剂和食品接触材料”以及“化妆品和家用产品”。这些EDC中的一些也在世界范围内大量生产或制造。最后,我们通过一个示例说明了精选的知识库(如DEDuCT 2.0)中的各种信息如何有助于EDC的风险评估。总而言之,我们强调需要弥合化学安全性在学术和法规方面之间的差距,以迈向更好地管理环境和健康危害(例如EDC)的一步。0有助于EDC的风险评估。总而言之,我们强调需要弥合化学安全性在学术和法规方面之间的差距,以迈向更好地管理环境和健康危害(例如EDC)的一步。0有助于EDC的风险评估。总而言之,我们强调需要弥合化学安全性在学术和法规方面之间的差距,以迈向更好地管理环境和健康危害(例如EDC)的一步。
