The North Sea is one of the most studied and exploited ecosystems worldwide. The multiple uses from industrial, transport, as well as recreational activities have required researchers, regulators, and legislators to understand and, where possible, to minimize any expected negative environmental impacts. As with any international sea, assessing the current pressures and management actions resulting from these activities is centred on several national and international legislative instruments. This variety of co-existing legislations makes development processes and regulatory assessments cumbersome and time consuming. Hence there is a need to integrate environmental risk assessment and management across sectors, ensuring smart, cost-effective data generation, as well as supporting and standardizing environmental practices. This paper provides an overview of the changing regulatory frameworks regarding offshore chemicals used in the oil and gas industry, and the process of chemical risk assessment conducted under the Offshore Chemical Notification Scheme (ONCS) in the UK. Our view of methodological, research, and regulatory needs and challenges that should be addressed to ensure an adequate and sustainable assessment of offshore chemical use in the North Sea is discussed. Furthermore, we discuss the issues faced regarding chemicals used in the UK oil and gas sector with respect to declining hydrocarbon production.

英国对北海近海化学品法规的过去，现在和未来的看法

北海是全球研究和开发最多的生态系统之一。工业，交通运输和娱乐活动的多种用途要求研究人员，监管人员和立法人员了解并在可能的情况下最大程度地减少任何预期的负面环境影响。与任何国际海洋一样，评估这些活动造成的当前压力和管理行动的重点是一些国家和国际立法文书。多种共存的法规使开发过程和监管评估变得既麻烦又费时。因此，需要整合跨部门的环境风险评估和管理，以确保生成智能，具有成本效益的数据，并支持和规范环境实践。本文概述了有关石油和天然气行业中使用的离岸化学品的法规框架不断变化，以及在英国的离岸化学品通报计划（ONCS）下进行的化学风险评估过程。讨论了我们对方法，研究和监管需求以及应解决的挑战的观点，以确保对北海的近海化学品使用进行充分且可持续的评估。此外，我们讨论了与英国石油和天然气行业中使用的化学品有关的碳氢化合物产量下降所面临的问题。为了确保对北海近海化学品的使用进行充分，可持续的评估，我们讨论了应该解决的研究，监管需求和挑战。此外，我们讨论了与英国石油和天然气行业中使用的化学品有关的碳氢化合物产量下降所面临的问题。为了确保对北海近海化学品的使用进行充分，可持续的评估，我们讨论了应该解决的研究，监管需求和挑战。此外，我们讨论了与英国石油和天然气行业中使用的化学品有关的碳氢化合物产量下降所面临的问题。
