have all been linked to chem­i­cals that float in the air at room tem­per­a­ture, or volatile or­ganic com­pounds. In a new study, sci­en­tists have dis­cov­ered that sim­ply adding one medium-sized plant (of up to 50cm) to a medium-sized room (of about 4 x 5m) can in­crease in­te­rior air qual­ity by up to 25 per cent. Com­mis­sioned by Hort In­no­va­tion and de­liv­ered by sci­en­tists at RMIT Univer­sity and the Univer­sity of Mel­bourne, the study in­volved a meta-anal­y­sis of more than 100 re­search pa­pers from around the world.

Univer­sity of Mel­bourne re­searcher Do­minique Hes said the work was timely. “Hu­man be­ings are less and less among na­ture with cur­rent es­ti­mates in­di­cat­ing that ur­ban dwellers spend 90 per cent of their time in in­door en­vi­ron­ments – re­sult­ing in a high level of ex­po­sure to in­door con­tam­i­nant com­pounds,” she said.
