Evaluation of acute toxicity of IHPLUS® bioproduct on Eisenia fetida
Soils support production of most food crops. Thus, maintaining optimal conditions for their use constitutes a major challenge. Chemicals move into soils in different ways, leading to soil contamination. One of the diagnostic tools to evaluate this problem is ecotoxicology. The Center of Chemical Bio...

| description |
Soils support production of most food crops. Thus, maintaining optimal conditions for their use constitutes a major challenge. Chemicals move into soils in different ways, leading to soil contamination. One of the diagnostic tools to evaluate this problem is ecotoxicology. The Center of Chemical Bioactives has a battery of tests to evaluate the impact of chemical and biological products on biotic factors representative of different ecosystems. The objective of this work was to evaluate the impact of the IHPLUS® bioproduct on the soil ecosystem using Eisenia foetida as a bio-model. According to the methodology recommended by OECD 207, healthy individuals were exposed under controlled conditions to a single dose of the bioproduct for 28 days. The exposure doses matched those used in agriculture (6%) and those recommended by EPA´S OPPTS 885.4000 (106 CFU / mL). The endpoints evaluated were mortality and variation in worm body weight. In addition, other signs of behavioral changes were observed. No mortality occurred, and there was an increase in the average weight of specimens in the experimental groups. Slight, non-significant changes from the usual behavior were observed in some worms. According to our results, the use of the bioproduct IHPLUS® in agriculture is safe for this earthworm species. |

Los suelos son la fuente de la mayor parte de los alimentos del ser humano, constituyendo un desafío mantener las condiciones óptimas para su uso. Son contaminados con los productos químicos que, de varias formas, llegan a ellos. Una de las herramientas de diagnóstico para evaluar esta problemática lo constituye la ecotoxicología. El Centro de Bioactivos Químicos cuenta con una batería de ensayos para evaluar el impacto de productos químicos y biológicos sobre factores bióticos representativos de diferentes ecosistemas. El objetivo del presente trabajo fue evaluar el impacto en el ecosistema terrestre del bioproducto IHPLUS® mediante el empleo del biomodelo Eisenia fetida. Según la metodología recomendada por OECD 207, se seleccionaron individuos sanos y en condiciones controladas y se expusieron a dosis única durante 28 días al biopreparado. Las dosis de exposición correspondieron a la de uso en la agricultura (6 %) y a la recomendada por la EPA OPPTS 885.4000 (106 UFC/mL). Los puntos finales evaluados fueron la mortalidad y la variación del peso corporal de las lombrices. Además, se refirieron otros signos de cambios del comportamiento conductual. Al término del estudio no se observó mortalidad, y se evidenció un aumento de peso promedio de los especímenes en los grupos experimentales. Ligeros cambios no significativos del comportamiento habitual se apreciaron en algunas lombrices. El empleo del bioproducto IHPLUS® en la agricultura es seguro para esta especie del ecosistema terrestre. Os solos são a fonte da maioria dos alimentos do ser humano, e é um desafio manter as condições ideais para o seu uso. Estão contaminados com produtos químicos que, de várias maneiras, chegam até eles. Uma das ferramentas de diagnóstico para avaliar esse problema é a ecotoxicologia. O Centro de Bioativos Químicos possui uma bateria de testes para avaliar o impacto de produtos químicos e biológicos sobre fatores bióticos representativos de diferentes ecossistemas. O objetivo deste trabalho foi avaliar o impacto no ecossistema terrestre do bioproduto IHPLUS® por meio do biomodelo de Eisenia fetida. De acordo com a metodologia recomendada pela OCDE 207, indivíduos saudáveis foram selecionados em condições controladas e expostos a uma única dose da biopreparação durante 28 dias. As doses de exposição corresponderam à dose do uso na agricultura (6%) e a dose recomendada pela EPA OPPTS 885,4000 (106 UFC/mL). Os pontos finais avaliados foram mortalidade e variação do peso corporal dos vermes. Além disso, foram relatados outros sinais de mudanças comportamentais. No final do estudo, não foi observada mortalidade e houve aumento no peso médio dos espécimes nos grupos experimentais. Ligeiras alterações não significativas do comportamento habitual foram observadas em alguns vermes. O uso do bioproduto IHPLUS® na agricultura é seguro para esta espécie do ecossistema terrestre.
