รายละเอียด :
Sediment quality in global estuaries was reported by assessing the degree of anthropogenic input and the corresponding
ecological risks. This research intended to categorize the quantities of marine pollution at the mouth of the Chanthaburi
River, on the Eastern Gulf of Thailand, by examining the interactions amongst the heavy metals (Pb, Cd, Cu, Zn) and
microplastics (MPs) in surface marine sediments. Marine pollution severity was classified using the Geo-accumulation
Index (Igeo), Sediment Enrichment Factor (SEF), and Pollution Load Index (PLI). Spatial distribution of pollutants and
geostatistical covariance were examined via Geographic Information System (GIS) and Principal Component Analysis
(PCA). The average concentrations determined in sediment samples were as follows: Pb, 0.369 ± 0.022 ppm; Cd, 0.0042 ±
0.0004 ppm; Cu, 5.424 ± 0.007 ppm; Zn, 33.756 ± 0.182 ppm; and microplastics, 1.36 ± 0.06 particles/g. All metal levels
were below the WASV, CCV, and TRV reference thresholds. Igeo and SEF indicated that Zn was moderately accumulated
