A study was carried out to evaluate the extent of total petroleum hydrocarbon (TPH) and oil and grease (OG) pollution in the waters of Ramsar Gazetted mangrove area Johor during monsoon (February) and post-monsoon (May) 2013. The concentrations of TPH obtained using UV-fluorescence spectroscopy ranged between 6.50-80.3 (mean 20.2 15.7) g L-1 Tapis crude oil equivalent and OG using gravimetric analysis ranged from 0.06-1.50 (mean 0.37 0.28) mg L-1. Higher TPH in area surrounding the Kukup Island is probably due to illegal desludging and active shipping activities. The OG was found higher in the Strait of Kukup Island and Pulai River; high surface run-off of lipophilic matters from terrestrial and anthropogenic activities could have enriched the waterways. In general anthropogenic activities tidal influence and dynamic of mixing affected the distribution of OG and TPH in the study area. Values obtained were comparable to reported data elsewhere in Malaysian waters.

Abstract

A study was carried out to evaluate the extent of total petroleum hydrocarbon (TPH) and oil and grease (OG) pollution in the waters of Ramsar Gazetted mangrove area Johor during monsoon (February) and post-monsoon (May) 2013. The concentrations of TPH obtained using UV-fluorescence spectroscopy ranged between 6.50-80.3 (mean 20.2 15.7) g L-1 Tapis crude oil equivalent and OG using gravimetric analysis ranged from 0.06-1.50 (mean 0.37 0.28) mg L-1. Higher TPH in area surrounding the Kukup Island is probably due to illegal desludging and active shipping activities. The OG was found higher in the Strait of Kukup Island and Pulai River; high surface run-off of lipophilic matters from terrestrial and anthropogenic activities could have enriched the waterways. In general anthropogenic activities tidal influence and dynamic of mixing affected the distribution of OG and TPH in the study area. Values obtained were comparable to reported data elsewhere in Malaysian waters.
