碩士 / 國立臺灣海洋大學 / 海洋環境資訊學系 / 94 / The studies of Keelung harbor are mostly focused on the economic development. It is known well that the Keelung harbor is a seriously polluted environment. However, the study of water quality of the Keelung harbor is rare. The present study investigated the water quality of the Keelung harbor from September to December, 2005.
The survey results of water quality of the Keelung harbor were in the range: pH, 7.49-8.32 (average 8.02); dissolved oxygen, 0.49-6.73 ml/l (4.08ml/l); dissolved phosphate, 0.32-15.29 �嵱 (2.28 �嵱); silicate, 4.32-237 μM (27.7 �嵱); ammonium, 0.27-258 μM (29.62 �嵱); nitrite, 0.03-20.22 μM (2.54 �嵱); nitrate, 0.52-60.36 μM (12.97 �嵱); and chlorophyll a, 0.06-5.627 μg/l (0.76 μg/l). The relatively high concentrations of nutrients and extremely low concentrations of dissolved oxygen were generally found 1 km away the south bank within the harbor. The water quality in this region does not followed the “B level” seawater standard of EPA regulation. The spatial distribution of nutrient concentrations in the Keelung harbor showed significant decrease with seaward, while dissolved oxygen exhibited the reverse distribution. The results obtained in the present study suggest that the pollution sources of Keelung harbor primary come from domestic discharges. The influence of these discharges is generally restricted 1 km away of the input.
