The analysis of the scientific literature on the subject of bioremediation in Latin America countries shows that due to the excessive and uncontrolled use of pesticides in agriculture, there are negative impacts on the environment, mainly on soil and water, as well as on human health. However, through processes such as bioremediation, which utilize the metabolic potential of microorganisms such as bacteria and fungi, it is possible to reduce the impact of pesticides on the environment and human health, which are key factors for achieving sustainable development. Colombia has a severe pesticide pollution problem, as the uncontrolled use of pesticides has affected not only the environment but also human health. Thus, bioremediation is a good alternative to the restoration of a polluted environment and the reduction of its impact on human health.

“…These chemical substances show a tendency to bioaccumulate through trophic chains; as a result, high levels of toxicity are generated. This situation triggers potential health risks for species that interact with this kind of substances (Marín and Jaramillo 2015). There are three classes of symptoms stemming from organophosphorus-compound poisoning: muscarinic, nicotinic, and central nervous system (CNS) effects.…”

Pesticides containing organophosphorus compounds, such as chlorpyrifos (CPF), are frequently used in agricultural activities, and their use has been increasing due to the presence of multiple plant diseases which threaten the production of vegetable food products. As a result of this practice, the soils in question are often found to be contaminated due to the fact that these pesticides do not immediately degrade and hence remain for long periods of time. The objective of this study was to evaluate the degradation of CPF in the presence and absence of the worm Eisenia foetida (EF) in soils contaminated with 40 mg/kg of CPF during a 28-day period. The D group, whose soil was sterilized and in which no EF worms were present, yielded a CPF-degradation result of 33.68 %. The C group, in which the soil was unsterilized and there were no EF worms present, yielded a degradation percentage of 37.16 %. On the other hand, the B group, containing sterilized soil in which the EF worms were present, yielded a degradation percentage of 60.76 %. Finally, with the A group, in which the soil was unsterilized and EF worms were present, degraded in 74.85 %. Eisenia foetida (EF). En el grupo D, cuyo suelo estaba esterilizado y en ausencia de EF, se obtuvo una degradación del CPF de 33.68 %. En el grupo C, donde el suelo no estaba esterilizado y en ausencia de EF, se obtuvo un porcentaje de degradación de 37.16 %. Por otro lado, el grupo B, que contenía suelo esterilizado en presencia de EF, mostró un porcentaje de degradación de 60.76 %. Finalmente, el grupo A, cuyo suelo no estaba esterilizado y en presencia de EF, se degradó en un 74.85 %.

RESUMENEn los últimos años se ha encontrado cantidad de agroquímicos acumulados en suelos agrícolas que los vuelven infértiles, disminuye la calidad de los productos alimenticios, contaminan el suelo y aguas subterráneas. Un agroquímico utilizado de manera indiscriminada es el clorpirifos, principal producto de hidrólisis el 3,5,6-tricloro-2-piridinol.

En los últimos años se ha encontrado cantidad de agroquímicos acumulados en suelos agrícolas que los vuelven infértiles, disminuye la calidad de los productos alimenticios, contaminan el suelo y aguas subterráneas. Un agroquímico utilizado de manera indiscriminada es el clorpirifos, principal producto de hidrólisis el 3,5,6-tricloro-2-piridinol. En este proyecto se unen dos estrategias de biorremediación para mitigar la problemática de los agroquímicos, se realiza análisis sobre capacidades de degradación de microorganismos del suelo contaminado, identificación para potenciar la facultad de estos, determinación de concentraciones viables para realizar biodegradación en los suelos agrícolas y disminuir la tasa de contaminación en el ecosistema y los niveles de intoxicación al ser humano. El objetivo de esta investigación es analizar y evidenciar la biodegradación del pesticida clorpirifos a diferentes concentraciones de microorganismos y solución de nutrientes, con el propósito de nivelar la sobrecarga de agroquímicos y evitar una mayor contaminación en el suelo, cultivos y aguas subterráneas.
