In the late past tense , deterioration of indoor air timbre has become a serious concern due to the increased get-up-and-go efficiency and slim down air substitution rate inside urban construction . fickle constitutional compounds ( VOCs ) are a major category of indoor air pollutant that can contribute to contrary wellness issue such as headaches , allergic reaction and asthma in those exposed for protract periods . Formaldehyde , the VOC used in the present field , is a unwashed contaminant of indoor air that originates from subatomic particle board , plywood , paper intersection , sure adhesives , tobacco plant smoke and other reference .
The use of goods and services of industrial plant for the palliation of indoor air defilement is consider as a monetary value - effective and eco - favorable method with untapped potentiality . The chief objective of the present study was to determine the formaldehyde remotion efficacy of selected plant species while investigating the mechanisms used by these plant in the removal summons . The selected plant species were Zamioculcas zamiifolia , Hedera helix , Dracaena sanderiana and Ficus sp . Plants of the same age were used with three replicates from each species . Phytoremediation electric potential was assessed by exposing the plants for 24 hours to gaseous formaldehyde ( 2.0 µL L-1 ) in air - plastered chambers made of Plexiglass ( an inert material for VOCs ) with property of 0.9 chiliad height×0.58 m length×0.55 m width .
methanal removal was value using GC - MS , and the upshot was expressed as removal percentages . Several leafage anatomic quality ( cuticle heaviness , epidermal heaviness and mesophyll level thickness ) , stomatal characters ( stomatal density , stomatal index , guard electric cell length and potential conductance index ) , and physiological characters ( stomatous conductance and photosynthetic pace ) were measure to study the potential mechanisms involved in the formaldehyde removal unconscious process . The data were subjected to ANOVA and Pearson correlation trial . accord to the results obtained , Ficus sp . had the high methanal remotion percentage ( 92.80 % ) , while Hedera helix had the lowest ( 56.86 % ) .
The field of study further showed that stomatal density and stomatous conductance play a major role in methanal removal by these plants , while cuticle and epidermal thickness act as hindrances to this process . This conclusion was further reassert by Pearson ’s correlativity economic value in correlativity analytic thinking .
The current subject area was carry out for 24 hours of exposure , and it would be of interest to search , the long - term deportment of the plant life through further studies . Overall , the result justify next subject area on a cross - subdivision of diverse flora species for formaldehyde remotion efficiency to find out species with superior removal efficiencies for a better phytoremediation process .
