Performic acid toxicity studies on stabilized HEp-2 cells
Summary
Performic acid, a potent disinfectant, showed greater cytotoxicity to HEp-2 cells than peracetic acid. Lower concentrations inhibited cell growth, while very low concentrations had minimal impact.
Area of Science:
- Biotechnology
- Toxicology
- Cell Biology
Background:
- Performic acid is utilized as a disinfectant, sterilant, and antiseptic.
- Assessing its biotolerance and comparing it to peracetic acid is crucial due to its applications.
Purpose of the Study:
- To evaluate the in vitro toxicity of performic acid on cultured HEp-2 cells.
- To compare the biotolerance of performic acid with that of peracetic acid.
Main Methods:
- Cultured HEp-2 cells were exposed to varying concentrations of performic acid.
- Cellular morphology, growth inhibition, and viability were assessed post-treatment.
- Comparative analysis with peracetic acid treatments at identical concentrations was performed.
Main Results:
- Distinct cytotoxic effects were observed at performic acid concentrations of 0.05% and higher.
- Lower concentrations (0.000005% to 0.005%) exhibited minor morphological effects but inhibited cell growth.
- Performic acid demonstrated greater toxicity to HEp-2 cells compared to peracetic acid at equivalent concentrations.
Conclusions:
- Performic acid exhibits significant cytotoxicity, with effects being concentration-dependent.
- Cell cultures serve as a valuable in vitro model for assessing chemical toxicity.
- Performic acid's biotolerance is lower than that of peracetic acid, necessitating careful handling and application.
