Occurrence and Assessment of Organic Pollutants Residues in the Aquatic Environment of the Coastal Sediments

The current study aimed to monitor organic pollution on island and coastal environments using linear alkylbenzene (LAB). aquatic environment is affected by the hazardous chemicals discharged through domestic industrial waste. distribution, composition, sources of LABs in sediments Port Dickson coast Pulau Merambong were identified gas chromatography–mass spectrometry (GC–MS). Chains ranging from long short (L/S), C13/C12 homologs, internal external (I/E) congeners used define degradation rate efficacy wastewater treatment plants. results this revealed that concentration sites under investigation varied 67.4 255.8 ng g?1dw, Dickson. LAB homologs had a significant difference percentage sampling stations C13-LAB homologs. According determined ratios (I/E), which ranged 1.6 4.1 Dickson, treated effluents primary secondary inputs are being introduced into ecosystem these areas. was up 64% interrogated locations. conclusion system needs be improved, molecular markers highly effective tracing anthropogenic sewage contamination.
