Abstract

This study assesses the spatial and temporal physico-chemical quality of the surface waters of Moulouya River based on the global pollution index PI. Several physico-chemical parameters (T°C, pH, electrical conductivity (EC), dissolved Oxygen (DO), BOD5, PO4 3−, NH4 +, SO4 2− and NO3 −) were monitored on 66 samples collected in 2014 during three campaigns at 22 stations from the upper reaches in the Upper Moulouya to its mouth in the Mediterranean. The results show that 86.4% of the stations show no pollution and are mainly located upstream of Moulouya river during the three campaigns of 2014 (March–April, May–June and July–August). However, the Zaida (M6), Missour (M12) and Gercif (M16) stations have polluted waters related to the very high levels of ammonium, nitrates, sulphates, phosphates and DBO5, which exceed Moroccan standards and would be related to the anthropogenic impact of agricultural fertilizers and urban and industrial wastes.

污染指数与GIS在摩洛哥东北部穆卢亚河地表水理化质量评价中的贡献

基于全球污染指数PI，对毛骆雅河地表水的时空理化质量进行了评价。对2014年从上穆卢亚河上游到地中海河口的22个监测站采集的66个样品进行了3次监测，其中包括温度、pH、电导率(EC)、溶解氧(DO)、BOD5、PO4 3−、NH4 +、SO4 2−和NO3−。结果表明:2014年3 - 4月、5 - 6月和7 - 8月3个运动期间，有86.4%的监测站处于无污染状态，且主要分布在木罗雅河上游。然而，Zaida (M6)、Missour (M12)和Gercif (M16)站的水污染与铵、硝酸盐、硫酸盐、磷酸盐和DBO5的含量非常高有关，超过了摩洛哥的标准，这可能与农业肥料和城市和工业废物的人为影响有关。

期刊介绍： La Houille Blanche, revue internationale de l ''eau/International Water Journal, is the only almost all French-written journal of Water science. It promotes the dissemination of research and innovative practices in the field of water, as a key resource for everyday use for human needs, agriculture, energy and transport, and hydraulic public works. This includes environmental and risk assessment and management issues related to hydrology, meteorology, flood, low flows and drought, as well as issues in the field of fluid mechanics, hydraulics machinery, multiphase flows, microfluidics... La Houille Blanche, International Water Journal, is cited by Science Citation Index Expanded of Institute for Scientific Information (I.S.I) in USA, and by CNRS in France; since 1902, the journal publishes high-standard relevant peer-reviewed research papers. La Houille Blanche also provides more general information and recent news about the water world, and the SHF association and its members life: scientific events, book review, R & D advancements, … Six issues per year. Thematical journal for original articles and reviews mostly in French.
