摘要

在墨西哥，大约90%的河流主要受到废水的污染，造成人类健康问题。本研究旨在确定库帕蒂齐奥河的水质;在雨季(2016年8月)和旱季(2017年5月)确定了20个采样点;测定了31种微量元素(TE)和15个理化参数;计算了三个质量指数:水质指数(WQI)、污染指数(IC)和加拿大环境部长理事会水质指数(CCMEWQI)。对关联变量进行统计分析。结果表明:雨季水质指标表明，中游流域因垃圾填埋废水和渗滤液污染水质最差;在旱季，低质量到达低分水岭。中下游流域存在高浓度的铁、铝、磷微量元素。值得一提的是，它们可能与牛油果果园使用的农药有关。最后，分析表明，质量差、溶解氧低与储层存在关联。因此，河水不适合人类使用和消费。

Evaluation of the physical and chemical quality and trace elements of water in Cupatitzio River, Michoacán

In Mexico, around 90 % of the rivers are polluted mainly from wastewater resulting in human health issues. This work is aimed at determining the water quality of Cupatitzio River; 20 sampling sites (SS) were determined in rainy (August 2016) and dry (May 2017) seasons; 31 trace elements (TE) were obtained and 15 physicochemical parameters; three quality indices were calculated: Water Quality Index (WQI), Pollution Index (IC) and the Canadian Council of Ministers of the Environment, Water Quality Index (CCMEWQI). Statistical analysis was conducted to associate variables. Results show for the rainy season, the quality indices indicates that the worst quality is found in the middle watershed due to the wastewater and leachate from a landfill; in the dry season, low quality reaches the low watershed. High concentrations of Fe, Al and P trace elements are found in the middle and lower watershed. It is worth mentioning that they may be associated with the pesticides used in avocado orchards. Finally, analyses show an association between poor quality, low dissolved oxygen and the presence of reservoirs. Therefore, the river water is not fit for human use and consumption.

期刊介绍： Published by the Mexican Institute of Water Technology, Water Technology and Sciences (Tecnología y ciencias del agua) is a highly specialized journal which reflects two important characteristics: The interdisciplinary nature of its articles and notes. The international scope of its authors, editors, reviewers, and readers. It constitutes the continuity of the journal Irrigación en México (Irrigation in Mexico) (1930-1946); Ingeniería hidráulica en México (Hydraulic Engineering in Mexico) (1947-1971); Recursos hidráulicos (Hydraulic Resources) (1972-1978), and Ingeniería hidráulica en México, second period (1985-2009). The journal is aimed at researchers, academics, and professionals who are interested in finding solutions to problems related to the water. The journal’s contents are interdisciplinary and contain previously unpublished articles and notes that offer original scientific and technological contribution that are developed in the fields of knowledge related to the following disciplines: Water and energy. Water quality. Hydro-agricultural sciences. Political and social science. Water management. Hydrology. Hydraulics.
