| Sumario: | Given the human need to collect freshwater, man has designed reservoirs built with different types of materials whose collection volume is highly variable. From large dams to small reservoirs for agricultural, domestic and other uses. Many of these with great potential to develop aquaculture activities. In northeastern Mexico, given the climatic conditions, artificial reservoirs take on strategic importance for the use and aprovechamiento of the vital liquid. In Mexico, the General Law of Ecological Equilibrium and Environmental Protection classifies Cadmium and Lead as hazardous waste potentially toxic to the environment and human health, since there are both natural and anthropogenic sources of pollution that represent a risk of contamination to the environment. The present study was carried out in an artificial reservoir in northeastern Mexico, in which the water quality was analyzed to determine the presence of heavy metals such as Cd, Pb. Given the anthropogenic activity in the area, water samples were collected during the autumn and winter seasons, at sites determined by the use of remotely piloted aircraft systems (RPAS). The results obtained by the spectrophotometry technique showed the presence of Cadmium (Cd), showing significant differences between the maximums and minimums between the collection points. In the case of Lead (Pb), its presence was minimal, and it is finally concluded that anthropogenic activity does not represent a source of emission of pollutants for the reservoir. |
