| Abstract: | Present study reports cytotoxicity of Carbon
Nanoparticles to Navicula and Isochrysis. Cytotoxicity was determined
by morphological changes, cell density count, Acid Phosphatase and Lactate
dehydrogenase assays. Carbon nanoparticles (CNPs) promote concentration as well
as exposure dependent toxicity to Navicula & Isochrysis, which exhibited
cell death, necrotic changes such as cell shrinkage and pycnosis of nucleus. Lactate
Dehydrogenase (LDH) & Acid Phosphatase (ACP) activities elevated
significantly, in both algae, in a dose and exposure dependant manner. In
Navicula and Isochrysis, LDH activity was elevated by 42.3% and 60.7%, and
44.5% and 90.3%, on exposure to 0.05 mg/mL and 1 mg/mL CNPs for
10 days respectively. Similarly, ACP activity in both Navicula and Isochrysis
was elevated by 34.6% and 55.4%, and 11.7% and 18.5%, on exposure to 0.05 mg/mL
and 1 mg/mL of CNPs for 10 days respectively, as compared to the controls. The
occurrence of tube like structures under the influence of CNPs in algae was
also observed. |
