Biostimulation of soil polluted by 40000 ppm of waste motor oil and phytoremediation with Cicer arietinum and Burkholderia cepacia. J. Selva Andina Res. Soc. [online]. 2016, vol.7, n.2, pp.76-85.

Soil polluted by 40000 ppm of waste residual oil (WRO), is a relative high hydrocarbons mix concentration according to Mexican regulation related with as the well know NOM-138-SEMARNAT/SSA1-2003 (NOM-138). Due to cause lost soil´s fertility, inhibiting microbial life and reducing vegetal production. To NOM-138 the highest limit of hydrocarbons mix allowed in soil is equal to 4400 ppm/kg. Aims of this research were: i) Biostimulation of soil polluted by 40000 ppm of WRO by vermicompost and/or bovine compost, ii) Phytoremediation by Cicer arietinum and Burkholderia cepacia to reduce WRO at below value compared to highest according to NOM-138. Results showed that biostimulation of soil with bovine compost eliminated WRO at 24000 ppm in 49 days. Then phytoremediation by C. arietinum and B. cepacia decreased WRO at 2760 ppm value below to compare to highest concentration allowed to NOM-138. It´s concluded that bioremediation of soil impacted by relatively high concentration of WRO, the best strategy was to apply both biostimulation/phytoremediation that separate.
