Use of bioindicators

A bioindicator is a living organism that can be anything from a microbe, an insect or a fish, to a plant or algae, which allows us to quantify and qualify the level and evolution of pollution present in an aquatic system, determining by virtue of its differential sensitivity. to various toxic substances. The sampling of macroinvertebrates joins the sampling of the chemical quality of the water. The reason for this is quite simple, the process of identifying source water contamination using water analysis alone is time-consuming and only provides limited information regarding the timing of sampling. Therefore, a sample of macroinvertebrates can serve as an indicator of water quality, providing more information about contamination or general water quality that is not present at the time the sample is taken. The approach to agriculture lies in the fact that most crops require a certain water quality for their proper development, and performing a laboratory analysis is generally difficult to access and high cost, so a study of bioindicators It is an alternative for people who require this type of analysis. The technology consists of participatory macroinvertebrate monitoring of communities, institutions and authorities, to sample bioindicators. It should be noted that the intervention of entities that validate and verify the analyzes carried out is important.
