Nanotoxicity nano-threat to nature

Production of nanoparticles is ever increasing with concomitant development of nanotechnologies. Current core concern is
on the biological properties of nanoparticles and in fact is a subject of active consideration. Till date, no specific conclusion
is derived about their actual harmful effects. Recent nanotoxicity studies have mainly focused on the health risks to healthy
adult human population. The nanotoxicity effects on susceptible organisms with simpler systems such as bacteria, earthworms,
fishes, chick embryos have often been overlooked. Since the morphological, anatomical, physiological and genetic structures
differ in these organisms, from those as in human, they often suffer more damage from the same exposure. Therefore, the
present comprehensive study was initiated to check possible toxicity of single walled carbon nanotubes (SWCNT) and
multi-walled carbon nanotubes (MWCNT) in sensitive biological systems like growth of E. coli and S. aureus, micronuclei
in earthworm coelomocytes, fish gill chromosomes, skeletal defects in chicken embryos and compared with damage in bone
marrow chromosomes of mouse and chromosomal aberrations in human peripheral blood lymphocytes, after acute or chronic
in vitro exposure. Virtually in all biological systems studied, we found toxicity of both SWCNT as well as MWCNT. The present
study describes in details fine analysis of toxicity in different systems explaining probable mechanisms of nanotoxicity. For
studying nanomaterial interactions, novel approaches are required since they are novel chemicals. In order to foresee and
prevent the potentially harmful effects of nanoparticles in nature, on health and the environment in particular, the results of
the present study will be of considerable help.
