Which vegetation found on rocks and trees could be a low cost way to monitor urban pollution ?
Mosses
Lichens
Algae
Both 1 and 2
Delicate mosses found on rocks and trees in cities around the world can be used to measure the impact of atmospheric change.
These could prove a low-cost way to monitor urban pollution, according to Japanese scientists.The “bioindicator” responds to pollution or drought-stress by changing shape, density or disappearing, allowing scientists to calculate atmospheric alterations.
This method is very cost effective and important for getting information about atmospheric conditions.Mosses are a common plant in all cities so we can use this method in many countries,they have a big potential to be bioindicators with nearly 50 types of moss analysed for the study.The humid cities where moss thrives could benefit most from using bryophytes–a collective term for mosses, hornworts and liverworts–as bioindicators, adding moss could be monitored in its natural environment or cultivated for analysis.
