ALUMINUM EFFECTS IN ALLEATO 80 WG FUNGICIDE ON EISENIA FOETIDA SPECIES

Journal Title: Current Trends in Natural Sciences - Year 2015, Vol 4, Issue 7

Abstract

The study highlights the influence of Alleato 80WG used in the laboratory chronic test, on an artificial soil according to OECD, on Eisenia foetida species, in terms of survival rate, biomass and content of bioaccumulated aluminum.50 mature individuals were used for each concentration in 5 repetitions (10 individuals / repetition). The toxic concentrations used were: LC50= 500 mg·Kg-1(V1); LC50= 400 mg·Kg-1(V2); LC50= 300 mg·Kg-1(V3); LC50= 200 mg·Kg-1(V4)/ dry soil, for 5 samples, the 5th (V5) being the control sample. The toxic concentrations in V1; V2 and V3, caused a significant decrease of the survival rate. The average values were 80%, as compared to V4 and control sample (V5). The correlations between Alleato 80 WG and the survival rate were negative (p<0.0001) while the increase of toxic concentration caused the decrease of the survival rate. After being subjected to toxic Alleato 80WG, biomass recorded for individual variants V1, V2, V3, and V4 does not differ significantly from version V5. The increase of toxic concentrations caused a significant increase of aluminum bioaccumulated by earthworms (R Square=0.304; p=0.004).
