Proactive approach to minimize lithium pollution

With the advancements in lithium-ion battery technology, lithium has been extensively used in many electronic products. Lithium usage is expected to increase in the coming decades. Elevated levels of lithium in the environments, including source water and biota, have been recently reported. Lithium can cause soil dispersion and aggerate swelling and can be readily taken up by plants and filter-feeders, potentially causing toxicity to plants, organisms, and human. As learnt from the reactive approach of the Clean Water Act, many emerging pollutants have not been recognized until they have been widespread and reached dangerous levels in the environments. Aftermath cleanup costs are huge, and many of these damages are irreversible. To avoid lithium being the next global contaminant of emerging concern, environmental agencies shall implement proactive regulation and education soon.
