At present, have reported problems of petroleum hydrocarbon contamination more coastal structures, this thesis has studied the petroleum hydrocarbon. (TPH) in contaminated sediment area in the province. 3 include running bull beach, sand beach, coconut and some samples were collected 2 times. In the dry season (March) and the rainy season (July) using Core sampler to sample. The extract for petroleum hydrocarbon contamination in sediment by using Automated and Soxhlet Extraction ใช้เทคนิค fluorescent Spectroscopy (UV Fluorescence Spectroscopy) in the determination of petroleum hydrocarbons, it was found that the average concentration of petroleum hydrocarbons as high on the beach, bull run. Convert (0.330 0.42 UG /), followed by Beach (0.195 edge 0.16 UG /) and some beach coconut (0.186 edge 0.14 why UG / g). Respectively, which both the concentration of petroleum hydrocarbon 3 no difference significantly. Comparison of petroleum hydrocarbons by depth, it was found that the depth of 4-5 cm. The highest concentration of petroleum hydrocarbon (0.458 edge 0.39 UG /). Because the petroleum hydrocarbons are usually not accumulate on the surface. But tend to accumulate in areas where not much, so the area with the highest concentration 4-5 cm, is at a depth of 9-10 followed by cm. Convert (0.128 0.035 UG /), and the depth 0-1 cm (0.124 edge 0.09 UG /), respectively, it was found that the concentration of petroleum hydrocarbons, no statistically significant difference between seasons. (P > 0.05).
