Microplastics pollution in salt pans from the Maheshkhali Channel, Bangladesh

Abstract Microplastics (MP) were recognized as an emergent pollution problem due to their ubiquitous nature and bioaccumulative potential. Those present in salt for consumption could represent a human exposure route through dietary uptake. The current study, conducted in Bangladesh, reports micropla...
