Abstract
The present study entitled “Effect of indoor plants on household environment in Ludhiana
city” was undertaken to know the existing practices regarding the indoor plants adopted by
homemakers in the houses of Ludhiana city, to measure the effect of indoor plants on
household environment and to develop and test the efficacy of instructional booklet for the
knowledge empowerment regarding control of pollution with indoor plants. Study was carried
out in two randomly selected zones (Zone-B and Zone-D) of Ludhiana city. From each
selected zone, three localities (Zone-B = Harcharan nagar, Bhagat singh colony, Ziwan nagar
and from Zone-D = Hakikat nagar, Dugri phase 1, Krishna nagar) were further selected
randomly. From each selected locality 20 respondents living in 300 to 500 square yards
houses and indoor plants were purposively selected thus making total sample of 120
respondents. Results of the study revealed that majority of the homemakers were aware about
indoor plants but had low knowledge regarding different cultural practices of indoor plants.
Air-quality monitor, hygrometer and thermometer were used for objective assessment and
modified scale Odour Awareness Scale (OAS) was used. In all the rooms where indoor plants
were placed showed improvement in air quality both in the case of Carbon-dioxide where
majority of the houses lie in limit 501-999 ppm and in case of Carbon-monoxide where
majority of the houses lie in limit 0-3.5ppm. All the areas showed that both the gases were
well within the permissible limit (permissible limit 1000 ppm for carbon-dioxide whereas
permissible limit 9ppm for carbon-monoxide). Also showed improvement in humidity level
where majority of the houses had humidity limit above 60% and temperature limit above 24oC
where permissible limit is 60%. OAS revealed that people had maximum awareness for the
pleasant odours (MS=3.59). Therefore, it is concluded that significant knowledge
empowerment was observed in respondents after providing instructional booklet to them.
