Ô nhiễm hydrocacbone dầu mỏ tổng trong nước và trầm tích vùng biển ven bờ Cà Ná, tỉnh Ninh Thuận
Abstract
The paper presents the analysis results of total petroleum hydrocarbon (TPH) in the water and sediments of two surveys at 12 stations in the Ca Na sea area in Ninh Thuan province in April 2018 and December 2019. Water samples were extracted by liquid-liquid method with dichloromethane solvent, sediment samples extracted by Soxhlet method, and Dichlorometal. Analysis by gas chromatography with FID detector (GC-FID). The total hydrocarbon content is calculated from the carbon range C9 to C36. The results showed that the concentration of TPH in the water ranged from 1.2 to 32.3µg/l with an average of 11.9±6.2µg/l, nearshore stations in the north (Mui Dinh) have higher concentrations than in the south (Ca Na), the concentration in December 2019 was higher than in April 2018 at most stations. In the sediments, the average TPH content is 4.3µg/gdry, ranging from 1.7-11.0 µg/gdry, showing that the sediment here has not been contaminated with TPH.
