Currently, I will conduct a research on Polychlorinated Biphenyls (PCBs) in e-waste in DKI Jakarta-Indonesia. This research will be able to provide important information about the existence of PCBs in e-waste to the makers of electronics waste management policy in Indonesia primarily. This becomes very important because many of literature has found the harmful of PCBs substance on e-waste for the environment and human health. Related to that, I want to know the percentage of the weight of PCBs usage in electronics waste such as Refrigerator, Air Conditioner, Washing Machine, and Television.
