The international community has defined the responsible management of hazardous waste and chemicals as an important part of sustainable development by including it in Sustainable Development Goal 12. [20] Target 12.4 of this goal is to "achieve the environmentally sound management of chemicals and all wastes throughout their life cycle".
Such chemicals may have the ability to bioaccumulate and biomagnify and can biomagnify (i.e. become more concentrated) up to 70,000 times their original concentrations. [42] POPs can affect non-target organisms in the environment and increase risk to humans [43] by disruption in the endocrine, reproductive, and respiratory systems. [42]
