Abstract The lakes of Hanoi are important water resources for urban agriculture. The concentrations of 17α-ethinylestradiol in the water of three major lakes were found to range from 0.1 to 9.1 ng/L, peaking during the rainy season. Effects at levels from 1 ng/L to 1 µg/L on the germination of mung bean (Vigna radiata) and bok choy (Brassica rapa) were studied. Soaking the seeds in solutions containing 17α-ethinylestradiol at 10 ng/L and higher increased the germination rate of mung bean but not of bok choy. For the latter, irrigation after sowing with solutions containing 17α-ethinylestradiol at 10 ng/L and higher accelerated germination.

河内湖泊中17α-炔雌醇及其对种子萌发的影响

摘要 河内湖泊是都市农业的重要水资源。发现三个主要湖泊的水中 17α-炔雌醇的浓度范围为 0.1 至 9.1 ng/L，在雨季达到峰值。研究了 1 ng/L 到 1 µg/L 的浓度对绿豆（Vigna radiata）和白菜（Brassica rapa）发芽的影响。将种子浸泡在含有 10 ng/L 和更高浓度 17α-炔雌醇的溶液中会提高绿豆的发芽率，但不会提高白菜的发芽率。对于后者，播种后用含有 10 ng/L 的 17α-炔雌醇和更高的溶液进行灌溉，加速发芽。缩写：MNRE：自然资源和环境部；PE60：人口当量；USGS：美国地质调查局；SPE：固相萃取；EDTA：乙二胺四乙酸二钠；高效液相色谱法：高效液相色谱; ELISA：酶联免疫吸附测定；DOM：溶解有机物；EEQ：雌二醇当量
