List of plants studied Its results suggested that, in addition to absorbing carbon dioxide and releasing oxygen through photosynthesis, certain common indoor plants may also provide a natural way of removing volatile organic pollutants ( benzene, formaldehyde, and trichloroethylene were tested). The NASA Clean Air Study was a project led by the National Aeronautics and Space Administration ( NASA) in association with the Associated Landscape Contractors of America (ALCA) to research ways to clean the air in space stations. One of the plants in this study is Bamboo palm (Chamaedorea seifrizii)
