28. 专家组注意到，虽然许多军用和商用爆炸物质需要尖端的知识和工业设施才能生产，但一些自制物质用通常可获得的化学品就能制造。这些化学品的一系列普通、合法的用途引起人们对接触这些化学品加以法律限制的关注并要求改变这类化学品，使其不能在这方面发生化学作用，同时又具有除制造爆炸物以外的其他用途。专家组注意到正在进行这方面的研究，建议在技术上可行和经济上可承受的情况下继续进行这种研究并将其作为进一步管制的基础。
28. The Group of Experts noted that while many military and commercial explosives substances required sophisticated knowledge and industrial facilities to produce, a number of home-made substances could be produced from commonly available chemicals. The range of common, legitimate uses for those chemicals generally raised concerns about the application of legal restrictions on access and about requiring the alteration of such chemicals in ways that would render them inert while still preserving their utility for purposes other than pro-ducing explosives. The Group noted that research in those areas was ongoing, and recommended that it be continued and used as the basis for further controls, if and when that became technically feasible and eco-nomically viable.
