Contribución al estudio de las aguas del lago de Tequesquitengo, Estado de Morelos
Abstract
Certain physical, chemical and biological characteristics of Lake Tequesquitengo in the State of Morelos, are presented to enlighten on such a phenomenon as the mortality of the fish species, which occasionally occurs there.
The electric conductivity, (2.46 mmhos/cm3) and the total solid residue of its wáter (2.8‰) allow to classify it as being oligohaline. The total cation and anion analyses indicate a high Mg/Ca relation as well as concentration of sodium, sulphates and strontium; the later in concentrations of 1.0 ppm.
Values of dissolved O2 are eminently good in most localities sampled to a depth of 8 m (from 5.13 to 8.71 ml/l); from this depth downwards it tends to be anoxic... In order to continue, download the full paper in PDF.
