AbstractThis study compares the procedures of formal and informal e-waste recycling; and investigates the relationship between informal e-waste recycling and the health of residents living near the recycling facilities. The informal e-waste recycling facilities are mainly located in developing countries and are operated by illegally receiving e-waste from developed countries. In these informal recycling businesses, the procedures are raw and crude without any measures in pollution control and state-of-the-art technologies, suggesting the health of the workers and residents living nearby are at risk. By conducting human health risk assessment based on the data from Guiyu town located in China, the actual exposure level of PCDD/Fs for infants is estimated. The total exposure level of infants to PCDD/Fs in Guiyu is 61.5 pg WHO-TEQ 〖kg〗^(-1) 〖day〗^(-1); among the total exposure level, dietary route accounts for over 90%. The total exposure value has also exceeded the WHO standards by 61 times at most, which reflects a harmful level of local PCDD/Fs exposure to the infants and management measures are needed. Implication can be drawn that not only the infants, but also people living near the facilities of informal e-waste recycling, including the mothers and residents are under high level of exposure to PCDD/Fs and other hazardous chemicals presented in the recycling process. Management and regulations are the weaknesses of developing countries to handle the issues on e-waste. The study reviews the e-waste management and regulations in China, India and Nigeria; their common properties have been revealed, including the lack of enforcement and the misconceptions of e-waste. Regarding the national level of regulations and legislations, recommendations have been drawn. Measures in adopting licensing system for recycling business, adopting financial mechanism on top of the existing the Extended Producer Responsibility (EPR) system to limit the use of hazardous chemicals, setting up special department for better regulating and enforcing e-waste related issues and enhancing the public education towards e-waste are of benefits. The study suggests an action plan using China as an example to illustrate how the country could act upon the existing regulations and legislations of e-waste issues. The plan could also be adopted by the other developing countries regarding their own conditions.
