ABOUT THE FEASIBILITY OF INDOOR PLANTS IN EDUCATION AND RESEARCH LABORATORIES
Journal Title: Інженерні та освітні технології - Year 2013, Vol 2, Issue 2
Abstract
Indoor air composition and its negative effects on human health are described. The definition of properties of houseplants, which are useful for health and vital activity of human. The list of plants, that are best to grow in study and science laboratories, is given. The data of plants, that reduce the general containment of the microbiological cells in the air and absorb the toxic substances, are given in the article.
