Knowledge of the hazards and associated risks from chemicals discharged to the environment has grown considerably over the past 40 years. This improving awareness stems from advances in our ability to measure chemicals at low environmental concentrations, recognition of a range of effects on organisms, and a worldwide growth in expertise. Environmental scientists and companies have learned from the experiences of the past; in theory, the next generation of chemicals will cause less acute toxicity and be less environmentally persistent and bioaccumulative. However, researchers still struggle to establish whether the nonlethal effects associated with some modern chemicals and substances will have serious consequences for wildlife. Obtaining the resources to address issues associated with chemicals in the environment remains a challenge.

从过去学习并考虑化学品在环境中的未来

在过去的 40 年里,人们对排放到环境中的化学品的危害和相关风险的认识有了长足的进步。这种意识的提高源于我们在低环境浓度下测量化学物质的能力的进步、对对生物体的一系列影响的认识以及全球专业知识的增长。环境科学家和公司从过去的经验中吸取了教训;理论上,下一代化学品的急性毒性较低,环境持久性和生物累积性较低。然而,研究人员仍在努力确定与某些现代化学品和物质相关的非致命影响是否会对野生动物产生严重后果。获取资源以解决与环境中的化学品相关的问题仍然是一项挑战。
