Evaluación del proceso de biorremediación de suelos contaminados con pesticidas a través de biopilas con adición de dos inóculos diferentes en el Sector Gatazo Zambrano Cantón Colta Provincia de Chimborazo

Abstract

It was evaluated the bioremediation of soils of Gatazo Zambrano which was enriched with two organophosphate pesticides: profenofos and diazinon, chosen based on surveys of residents of the sector. The soil was subjected to two different treatments: Bocashi (Treatment A) and biostimulation (Treatment B). And a register variable temperature control (18-30°C), pH (6-8), humidity (30-60%) to keep them within the optimum range, in order to provide suitable conditions took for the microorganisms develop. To Bocashi was used as nutrient sources, natural and organic elements according to e ratio C/N of 28:1. Whereas for biostimulation resorted to inorganic nutrients, adding them according to the C/N/P 100/10/1, the process lasted 50 days. The results were collected by direct observation using as a research tool inventory; obtain that treatment had a rate of 98,49% for degradation dianizon and 90,73% for profenofos, which turned out to be the most efficient for both degradation and dianizon profenofos. Treatment B was optimized treatment B was the most effective comparing this time the influence of nitrogen degradation, so we worked with ratios C/N/P of 100:20:1 and 100:1:1, taking more control of the condition.
