Ecotoxicological effect of a pig manure digested sludge on earthworm (Eisenia fetida) and corn (Zea mays)

Pig Manure Digested Sludge (LDPC) is a byproduct of the treatment of organic waste by anaerobic digestion, implemented in agro-industrial pig farms that, by environmental legislation, must be treated and disposed of without affecting the environment. The ecotoxicological effects of LDPC on the earth...

Toxicological effect ID50 LD50 LOEC Sludge Efecto toxicológico DL50 DI50 Lodo LOEC Zea mays Pig Manure Digested Sludge (LDPC) is a byproduct of the treatment of organic waste by anaerobic digestion, implemented in agro-industrial pig farms that, by environmental legislation, must be treated and disposed of without affecting the environment. The ecotoxicological effects of LDPC on the earthworm (Eisenia fetida) and on corn (Zea mays) were evaluated using the indices of LD50 (medium lethal dose), ID50 (Medium inhibition dose), NOEC (No observable effects concentration) and LOEC (Lowest Observable Effect Concentration) indices to determine the level of risk of using LDPC as a soil fertilizer. The values of the LD50 in earthworm and DI50 in corn were 15,50% and 22,60%, respectively, while the evasion test revealed a direct relationship with the presence of LDPC, where from the dose 12,5% is considered a toxic environment for worms. The NOEC and LOEC for the earthworm (mortality and dry weight), and for corn (germination, inhibition, radicle, number of roots, coleoptile, height, number of leaves, wet weight and dry weight) determined values of 15,625% and 18,75%, for worms, and 25% and 50%, for corn, respectively. It is concluded that LDPC can be used as an organic fertilizer if doses that do not exceed the lethal and sublethal effects on the two evaluated species are employed, and if it does not harm the functional and biological quality of the soil. El Lodo Digerido de Purín de Cerdo (LDPC) es un subproducto del tratamiento de residuos orgánicos por digestión anaerobia, implementado en granjas agroindustriales porcinas que, por legislación ambiental, deben ser tratados y dispuestos sin que afecten al ambiente. Se evaluaron los efectos ecotoxicológicos del LDPC en la lombriz de tierra (Eisenia fetida) y en el maíz (Zea mays) mediante los índices de DL50 (dosis letal media), DI50 (Dosis de inhibición media), NOEC (Concentración de efectos no observables) y LOEC (Concentración más baja de efectos observables) que determinan el nivel de riesgo del empleo del LDPC como abono al suelo. Los valores de la DL50 en lombriz de tierra y DI50 en maíz fueron de 15,50% y 22,60%, respectivamente, mientras que en la prueba de evasión reveló una relación directa con la presencia del LDPC, donde a partir de la dosis de 12,5% es considerada un medio tóxico para las lombrices. El NOEC y LOEC para la lombriz (mortalidad y peso seco), y para el maíz (germinación, inhibición, radícula, número de raíces, coleóptilo, altura, número de hojas, peso húmedo y peso seco) determinaron valores de 15,625% y 18,75%, para las lombrices, y 25% y 50%, para el maíz, respectivamente. Se concluye que el LDPC puede ser empleado como abono orgánico si se emplean dosis que no superen los efectos letales y subletales de las dos especies evaluadas, y que no perjudiquen la calidad funcional y biológica del suelo.
