Abstract The aim of the study is to investigate leaching fluorescent dissolved organic matter (fDOM) from microplastics. In addition, this identifies connection between fDOM and microplastics in aquatic environment. Three‐dimensional excitation–emission matrix identified five fluorophores, that is, peak A, M, T, T uv , W parallel factor analysis modeling components, tryptophan‐like, p ‐hydroxy acetophenone, humic acid (C‐like), detergent‐like, fulvic (M‐like) urban surface water. Mimic experiments using commonly used synthetic plastic (like microplastics) Mili‐Q water under solar radiation dark environments demonstrate release plastic. Two fluorophore peaks were observed at Ex/Em = 250/302 nm 260/333 for expanded polystyrene polymer one low‐density polyethylene. Fluorophore component intensity exhibited notable associations with These findings indicated characteristics dynamics are influenced by Practitioner Points Fluorescent matters waters. Expanded (EPS) had shown two fluorophores Em/Ex 260/333. Low‐density polyethylene (LDPE) settings

Abstract This study aims to identify continuous water quality changes and fluorescence properties from urban rivers marine zones. Various types of natural anthropogenic sources derived dissolved organic matter (DOM) have been identified in this study. These include soil‐derived DOM, plant remnants, soluble particles produced when material partially decomposes is released by microorganisms, such as bacteria, algae, plants. DOM was characterized using a three‐dimensional excitation–emission matrix (3DEEM), parallel factor analysis (PARAFAC), parameters the Buriganga River, Dhaka Patenga Seaport, Chittagong, along with Shitalakshya small portion Padma Meghna River. To better understand data analysis, area divided into three central regions: industrial rivers, estuarine In river, 3DEEM PARAFAC five fluorophores (peaks: A, C, M, T, T uv ) components: detergent‐like, fulvic‐like, tryptophan or protein‐like, fulvic‐like (C‐type), which might originate activities sewage pollution. river zone, two known components, namely, fulvic acid (A‐type) an unknown photoproduct at Ex/Em = 295/368 (peak ).
