Distribution Of Microplastics In Tropical Estuarine Mangrove And The Leaching Of Heavy Metals Under The Influence Of Temperature And Ph

This study reports the microplastic distribution in Seberang Perai, Kuala Muda, Penaga and Balik Pulau estuaries of Penang. A total of 8775 microplastic pieces were collected, with abundance in coastal surface water, coastal bottom and estuarine sediment ranging between 201±21.214 - 1407±124.265 pcs...
