Background: Formaldehyde a commonly used embalming fluid for the preservation of cadavers, produces numerous short and long-term side effects on the students and staff working with it. Indoor plants have been shown to reduce atmospheric formaldehyde levels. The purpose of the study was to compare the efficacy of indoor plants in reducing formaldehyde levels in ambient air to levels deemed safe by WHO standards Methods: The study was conducted in the storage room of the Anatomical dissection hall. 7 potted plants of one variety were kept in the storage room for 14 days and the Formaldehyde reading was measured using a VOC (Volatile Organic Compound) monitor. Then the same was done with no plant. This cycle was repeated 2 more times, with 2 different plant varieties. The 3 varieties of plants used for this study were as follows: Sansevieria, Epipremnum aureum, Spathiphyllum. Results: The results were analysed and compared and it was determined that the effect of having a plant present versus having no plant present on the Formaldehyde concentration in the air was inconclusive as Sansevieria failed to reject the null hypothesis altogether (p-value>0.05), while Epipremnum aureum and Spathiphyllum rejected the null hypothesis (p-value<0.05), however they both had a weak positive correlation with Formaldehyde concentration. Conclusion: The efficacy of indoor plants in reducing formaldehyde levels in ambient air needs to be further explored and validated since all the prior studies conducted were in controlled environment and should be done in a real time scenario for its practical and beneficial uses.
