Polymer-resolved ecological risk of microplastics in the Vietnamese Mekong Delta: a secondary-data assessment using pollution load and polymer hazard indices
Microplastics (MPs; plastic particles smaller than 5 mm) are widely reported in the surface water and sediment of the Vietnamese Mekong Delta, but their ecological hazard has not been synthesised across the Delta. Because polymer types differ by orders of magnitude in the toxicity of their constituent monomers and addi...
