• W2829206435 abstract "蓝藻碎屑分解引起氮磷释放已受到广泛关注，但堆积的藻屑与沉积物交互作用引发污染物释放的效应知之甚少.采集于桥水库沉积物柱状样，设置5个藻屑添加组和对照组（无藻屑添加），恒温培养（27±1℃），模拟夏季温度条件下不同密度藻屑堆积下沉积物中碳氮磷释放特征.结果表明：藻屑堆积后加强了上覆水中溶解氧与硝态氮的消耗，5个藻屑添加组18小时后上覆水均处于厌氧状态.各实验组上覆水中的溶解性有机碳（DOC）浓度在第3小时增加，且SUVA₂₅₄值处于0.54~1.74 L/（mg·m）之间，说明DOC可能来源于藻源性释放.各藻屑添加组培养过程中上覆水的溶解性有机氮（DON）、铵态氮和正磷酸盐浓度持续增加，最高平均释放速率分别达4.44、0.20和0.03 mg/（L·h），分别为对照组的21.73、1.76和67.58倍；其中DON为溶解性总氮主要存在形态，在实验结束时DOC/DON比值降低，说明藻屑或者沉积物有机质短期内并未完全矿化，且DOC优先DON被微生物利用.因此蓝藻碎屑堆积增强了沉积物需氧量，加快沉积物与水之间的氮磷营养盐、DOC循环，从而对沉积物中污染物地球化学循环过程造成进一步的影响.;The release of nutrients caused by the algae detritus decomposition has been widely studied, however, little is known about the mechanism of pollutants release induced by the interaction of accumulated algae detritus with sediments. In order to simulate the release characteristics of nutrients after different density algal debris settled on sediments on the summer temperature condition, sediments cores were sampled from Yuqiao Reservoir Watershed and cultured with five density gradients addition treatments and control without algal detritus under constant temperature condition (27±1℃). Results showed that algal detritus enhanced oxygen consumption and nitrate reduction, and overlying water in addition treatments reached anaerobic condition after the incubation time of 18 hours. The concentration of dissolved organic carbon (DOC) in each addition treatment increased in three hours and the value of SUVA₂₅₄ varied between 0.54-1.74 L/(mg·m), suggested that DOC was mainly derived from algal detritus decomposition. The concentrations of dissolved organic nitrogen(DON), ammonia nitrogen and phosphate in five addition treatments increased gradually with the release rates of 4.44 mg/(L·h), 0.20 mg/(L·h) and 0.025 mg/(L·h), respectively, and was 21.73, 1.76, 67.58 times of the release rates of control, respectively. DON was the main form of dissolved total nitrogen(DTN). Subsequently, the decrease of DOC/DON at the end of incubation suggested that algal detritus and sediments organic matter were not completely mineralized in which DOC took priority over DON being consumed by microorganisms. In general, accumulated algal detritus strengthen benthic oxygen demand and then accelerate the microbial geochemical cycle of nutrients and DOC between the interface of water and sediment." @default.
