Abstract

Determination of Total Petroleum Hidrokarbon (TPH) through the Concentration of Oil and Grease (OG) in the Surface Sediment of Cimanuk Delta Waters, West Java. The Estuary of Delta Cimanuk is located in the coastal water of Indramayu, West Java. The pollution in the Cimanuk Delta was originated from households and industrial waste on coastal dan upland areas. Coupled with the traffic activities of fishing vessels at the fish landing (PPI) and fishing port (PP) bases around the waters, oil and grease contamination would be a threat as pollution in Indramayu coastal area. The major source of OG component on coastal waters was animal and vegetal fat and total petroleum hydrocarbon (TPH). The objectives of the study are to estimate the concentration and spatial distribution of TPH in the sediments of the Cimanuk watershed based on OG levels, and identifying the distribution of TPH-contaminated areas. Fourier Transform Infrared Spectroscopy (FTIR) instrument was applied to determine OG compounds in the sediment samples.  The results showed that OG concentrations in sediments were varied between <1 to 138.104 mg kg-1 dry weight (dw), while TPH was estimated at 0.24 ? 36.60 mg kg-1 dw. The highest concentrations of OG was observed on St-10 in the northeast coast. Compared to the threshold value of sediments quality guidelines according to ANZECC (OG: 280-550 mg kg-1 dw), the TPH levels in eighteen observation stations were within normal range. The increased pollutant intake in Cimanuk watershed will threat the estuary as well as its biodiversity.

Abstract

PAH pollutants from anthropogenic activities were released into Indramayu Coast and could potentially have negative effects on the environment. This study aimed to determine the distribution, source, and ecological risks of PAHs in the area. Seawater and sediment samples were collected and stored in glass bottles at 4 °C and then further processed in the laboratory. The samples were extracted with dichloromethane and n-hexane and then fractionated using a silica gel column, and finally injected into a Gas Chromatography-Mass Spectrometer (GCMS). The distribution of PAH compounds was detected in all sampling stations in varying amounts. PAH with low molecular weight (two to three rings) was predominant in seawater samples, while high molecular weight (four rings) was predominant in sediments. In addition, by using the molecular diagnostic ratio, the PAH source in Indramayu Coast was detected to be pyrogenic and petrogenic processes that come from anthropogenic activities. Exposure to PAH concentrations in this study posed a lower risk to sediment-dwelling organisms. However, further awareness and periodic monitoring are required to detect carcinogenic PAHs.
