CANADA: Up till now it was thought that tampons just serve as a feminine hygiene product that absorbs blood during menstruation but now a new study shows that tampons can do much more than that. They can help identify the pollution areas in rivers and streams that possibly came from waste water from baths, sinks, washing machines and showers.
Researchers were able to use tampons in absorbing chemicals that are present in toilet papers, shampoos as well as laundry detergents.
The lead author of the study, Professor David Lerner, said that, “More than a million homes have their waste water incorrectly connected into the surface water network, which means their sewage is being discharged into a river, rather than going to a treatment plant.”
detective work,” added Lerner, who co-authored a study on the new water pollution tracking strategy. The study was published on March 30 in the Water and Environment Journal.
Traditional methods for monitoring wastewater pollution is through fiber optic cables as well as spectrometers that require training to use as well as run much higher in cost than boxes of tampons according to researchers.
