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, that allows us to quantify and qualify the level and evolution of contamination present in an aquatic system by determining its differential sensitivity to various toxic substances. Sampling of macroinvertebrates is linked to sampling of the chemical quality of the water. The reason for this is quite simple, the process of identifying contamination of water sources using only water analysis takes a long time and only provides limited information regarding the time of sampling. Therefore, a sample of macroinvertebrates can serve as an indicator of water quality, by providing more information about contamination or the general quality of the water that is not present at the time of taking the sample. The approach to agriculture is based on the fact that most crops require a certain water quality for their proper development, and performing a laboratory analysis is usually difficult to access and expensive, so a study of bioindicators is an alternative for people who require this type of analysis. The technology consists of monitoring macroinvertebrates with the participation of communities, institutions and authorities, in order to sample bioindicators. It should be noted that the intervention of entities that validate and verify the analyses carried out is important.
