Adenine Ribonucleotides and Adenylate Energy Charge in the Sea Water along the Patoutzu Refuse Landfill Site
基隆八斗子垃圾填海場附近海域之腺嘌呤核苷酸鹽與腺嘌呤核苷能量
摘要
由民國六十五年十月以來，基隆市垃圾均以填海方式掩埋在八斗子海提內。民國七十二年七月六日至八日、十月三日和至五日、七十三年三月二十至二十二日及五月十五至十七日使用九連研究船曾調查四航次之水文、水質化學金化學與生態環境因子。調查結發展，八科附近海域略受到垃圾填海之有機性與無機性物理（如重金屬與營養鹽）之污染。這項污染對生物生活影響如何，必須研究瞭解。分析海水中含腺嘌呤核苷酸鹽與腺嘌呤核苷磷酸鹽（ATP, ADP及AMP）與腺嘌呤核苷能量（AEC），可以瞭解該海域生活之牲動性。八斗子附近海域上述四航分析結果發現ATP（介於119.26 ± 59.40與780.98 ± 203.76 ng/l之間）值比ADP（介於91.83 ± 18.95與443.91 ± 236.94 ng/l之間）為高，比AMP（＜33.51 ng/l與248.30 ± 149.50 ng/l之間）更高；AEC值（介於0.64 ± 0.03與0.82 ± 0.08之間）隨季節性與區域性變化。通常在靠近垃圾填海附近之海域海水含ATP及AMP較高，AEC值較低，反之，遠離垃圾場之海域含ATP及AEC值較高。本文曾由實驗數據，討論AEC與生態環境因子（如重金屬、營養鹽、葉綠素甲與基礎生產力等）之相互關係；更由金山、南灣、興達港與八斗子附近海域之AEC值相互比較，以期針對垃圾填海對八斗子附近海域生態環境之影響進行評估。結果顯示，八斗子垃圾填海對生物生長並未帶來太大壓力。

Since October 1976, the municipal wastes of the Keelung City have been disposed in the concrete wall sited at the Patoutzu coastal area. Hydrographical, chemical and ecological parameters, collected in the cruises during the periods of July 6 to 8, October 3 to 5, 1983, and March 20 to 22 and May 15 to 17, 1984, indicated that the organic wastes and heavy metals as well as inorganic nutrients were seeped from the refuse landfill sites. These abiotic chemicals may influence the biological activities in the marine ecosystem. Adenine ribonucleotides (ATP, ADP and AMP) and adenylate energy charge (AEC) ratios in the sea water, collected in the same cruises, have been studied as the measure of the marine biological activities in the Patoutzu coastal area. The results found that the contents of ATP (ranged from 119.26 ± 59.40 to 780.98 ± 203.76 ng/l) were larger than those of ADP (ranged from 91.83 ± 18.95 to 443.91 ± 236.94 ng/l) and AMP (less than 33.51 ng/l to 248.30±149.50 ng/l). The AEC ratios (ranged from 0.64 ± 0.03 to 0.82 ± 0.08) varied with seasons and locations. Generally, high contents of nucleotides and low AEC ratios were found in the stations near the rubbish heaps, and low contents of nucleotides (particularly ATP) and high AEC ratios were in the stations far away the refuse landfill sites. Based on the experimental data, collected in the Patoutzu coastal area, the relationships among ATP, AEC and other environmental parameters [such as heavy metals (lead and copper), inorganic nutrients (nitrite, nitrate, phosphate and silicate), chlorophyll a and primary productivity] have been evaluated. The environmental and ecological impact upon the marine ecosystem in the sea water along the Patoutzu rubbish heaps have been also studied through the comparisons of the data obtained in the Chinshan, Nanwan and Shinda coastal waters.
