Abstract
Earthworms are soil-based organisms of agricultural importance which have
been referred by all as the “farmer’s friend’’. The exposure of soil to heavy
metals are of serious concern. Chemically synthesized pesticides, heavy metals
are of great concern to the environmentalists as well as the end users.
Nanoparticles are materials which are one- billionth in size. Bimetallic
nanoparticles are a combination of two different metallic core structures.
Chemically synthesized nanoparticles have been reported to possess heavy
toxicity to organisms including soil- based organisms. But, biogenic
nanoparticles are the ones which are synthesized by environmentally friendly
approaches using biologically derived products in agriculture. Hence, biogenic
nanoparticles are being preferred over chemically synthesized nanoparticles. Lumbricus
terrestrius is an earthworm which is commonly found in the Indian
peninsula. The silver oxide- bismuth nanoparticles have been characterized by
UV spectrometry. The natural soils were spiked with cow dung. The toxicity
profiling was also carried out by naked eye analysis and movement analysis. The
toxicity of nanoparticles biogenically synthesized were found to be less when
compared to chemically synthesized ones. The anomalous weight gains and weight
losses were seen in all concentrations selected in the earthworms Lumbricus
terrestrius. Out of 22 test earthworms, 8 earthworms died whereas in the
control, all three of the earthworms survived. This justifies the anomaly in
the toxicity wherein random weight gains and weight losses and deaths were
recorded even due to the supposedly biogenic nanoparticles.
