以云南洱海罗时江河口湿地为典型对象,利用柱状底泥分层采样器采集罗时江河口湿地表层(0~10 cm)、中层(10~30 cm)和底层(30~60 cm)沉积物样品,分析干、湿季沉积物总氮(TN)、总磷(TP)、有机质(OM)垂向分布特征,并对沉积物进行污染风险评价. 结果表明:①干季罗时江河口湿地表层、中层和底层沉积物TN平均含量分别为1.734、1.453和1.255 g·kg-1,TP平均值分别...
氨是生活垃圾填埋场产生的主要恶臭物质之一,同时也是PM2.5的重要前体物. 依据环境空气氨测定和无组织废气监测方法,研究了北京市两家垃圾填埋场的工艺关键点和厂界的氨浓度水平. 结果表明填埋作业面、污泥处理车间和渗滤液调节池等工艺关键点的氨浓度为0.078~0.341 mg·m-3. 工艺关键点的氨浓度呈现日间高、夜间低的特点,温度和湿度是主要气象影响因素,阴雨天气时监测结果明显偏低. 氨浓度在厂界...
使用在线色谱观测了冬季某化工区典型雾霾污染时段VOCs污染特征,同时应用PMF模型对化工区VOCs来源进行分析. 结果表明,观测期间VOCs主要组分是甲苯、二甲苯、C3~C4烷烃和氯仿等,有机硫组分是化工区异味的主要来源之一. 2个高污染时段内主要污染因子为异丁烷、正丁烷、丙烷和丙烯腈这4种组分. VOCs和NOx具有夜间高而白天低的日变化特征,体现了其主要受化工区排放源的影响. O3的日变化特征...
为揭示滇池水生植物分布对沉积物间隙水磷的质量浓度的影响,分别采集滇池有植物区域和无植物区域沉积物柱状样,测定间隙水和上覆水溶解性总磷(DTP)、溶解性活性磷(SRP)和溶解性有机磷(DOP)的质量浓度,分析其沉积物间隙水磷的垂向变化特征,探讨水生植物对沉积物间隙水磷形态特征的影响及控制效果,结果表明:①水生植物对滇池不同湖区沉积物间隙水各形态磷的质量浓度影响显著,但因分布站点不同、深度层次变化所呈...
