Lake Uluabat, known for its scenic beauty and richness of aquatic life, is situated in Marmara Region, Bursa (Turkey). On account of its importance, lake Uluabat was designated by the Ministry of Environment as a Ramsar site in 1998. Physical, chemical and microbiological parameters of the aquatic ecosystem in lake Uluabat were measured monthly at five stations from February 2003 to January 2004. The results showed that lake Uluabat can be classified as Class I with respect to temperature (16.36 +/- 7.47 degrees C), nitrate nitrogen (0.63 +/- 0.50 mgl(-1)), sodium (9.64 +/- 2.78 mgl(-1)), chloride (20.45 +/- 4.59 mgl(-1)), sulphate (54.80 +/- 29.97 mgl(-1)); as Class II with respect to dissolved oxygen (7.62 +/- 1.99 mgl(-1)), ammonium nitrogen (0.52 +/- 0.49 mgl(-1)), chemical oxygen demand (35.74 +/- 10.66 mgl(-1)), total coliform (2027 MPN100 ml(-1) (average value)); as Class III with respect to pH (8.69 +/- 0.16) and as Class IV with respect to total nitrogen (84.94 +/- 66.13 mgl(-1)), total phosphorus (1.11 +/- 3.01 mgl(-1)), biochemical oxygen demand (21.21 +/- 6.60 mgl(-1)) according to TWPCR (Turkey Water Pollution Control Regulation). The nutrient content of lake waterapparently indicated that lake had an eutrophic characteristic. Phosphorus was determined as a limiting factor in lake. The measured hardness values (140.94 +/- 14.61 CaCO3 mgl(-1)) indicated that lake water was classified as soft/hard during the study period. Eutrophic characteristic of the lake and contaminant accumulation in water will probably affect the future use of the lake. Therefore, pollution parameters must be regularly monitored and evaluated according to aquatic living and local regulations.
乌鲁阿巴特湖以其秀丽的风景和丰富的水生生物而闻名，位于土耳其布尔萨的马尔马拉地区。鉴于其重要性，乌鲁阿巴特湖在1998年被环境部指定为拉姆萨尔湿地。2003年2月至2004年1月期间，每月在五个站点对乌鲁阿巴特湖水生生态系统的物理、化学和微生物参数进行测量。结果表明，根据土耳其水污染控制法规（TWPCR），乌鲁阿巴特湖在温度（16.36±7.47摄氏度）、硝酸盐氮（0.63±0.50毫克/升）、钠（9.64±2.78毫克/升）、氯化物（20.45±4.59毫克/升）、硫酸盐（54.80±29.97毫克/升）方面可归类为I类；在溶解氧（7.62±1.99毫克/升）、铵氮（0.52±0.49毫克/升）、化学需氧量（35.74±10.66毫克/升）、总大肠菌群（2027个/100毫升（平均值））方面可归类为II类；在pH值（8.69±0.16）方面可归类为III类；在总氮（84.94±66.13毫克/升）、总磷（1.11±3.01毫克/升）生化需氧量（21.21±6.60毫克/升）方面可归类为IV类。湖水的营养成分明显表明该湖具有富营养化特征。磷被确定为该湖的限制因素。测量的硬度值（140.94±14.61碳酸钙毫克/升）表明，在研究期间湖水被归类为软/硬水。该湖的富营养化特征和水中污染物的积累可能会影响该湖未来的使用。因此，必须根据水生生物和当地法规定期监测和评估污染参数。
