E-waste scenario in South-Asia: an emerging risk to environment and public health.

Over the past decade, e-waste generation has been accelerated in the world as never before, particularly South-Asia is confronted with an enormous risk of e-waste intensification owing to both locally generated and internationally imported. There has been a gradual increase of e-waste generated in South-Asia and in 2019, 4,057 Kilo tons (kt) of e-waste was generated, which is about 16% of the Asian region. Though there is an urgent requirement to rectify the catastrophic accumulation of e-waste and for its effective eco-friendly management, inadequate legal implementation and poor enforcement, lack of awareness, weak formal e-waste collection and recycling process allow for escalating problems associated with e-waste, particularly towards the environmental and public health concern. Under these circumstances, this paper has been written by reviewing the available research findings, since 2000 to find out the current scenario of South-Asia. Unfortunately, the problem is also not seen as a hot topic to address by the researchers, there are only 106 research studies conducted in South-Asia. Out of that, a considerable number of studies were conducted only in India (54%), Bangladesh (23%), and Pakistan (16%). Sri Lanka, Nepal, and Bhutan shared the rest. As a matter of fact, many more studies are needed on environmental and human health effects, legal implementations, awareness and novel managerial strategies etc. to assist policymakers and other relevant authorities in making their decisions. Similarly, rather than facing threats alone, fighting against as a region would be ideal, which also helps to restrict intra movement of e-waste among the South-Asian countries.
