I was fascinated by news of a study by University of Adelaide of monitoring drugs in the sewerage system. It’s quite an innovative approach to mining sewerage data.
The drugs detected (and passed by people at the toilet) show alarming increases, especially with methamphetamine (ice).
There are differences between types of drugs used in the country vs. in metro Adelaide.
Samples were taken from 15 sewage treatment plants across South Australia and tested for traces of ecstasy, methamphetamines and cocaine.
There is increased use of methamphetamine over the weekend.
Methamphetamine was the drug of choice in the city, while country people preferred ecstasy. Cocaine was last on the list everywhere.I’m curious about the stated intention to develop a biomarker to determine how many humans contribute to the flow (of data). At the moment, there are only estimates of the population size served by each sewage plant.
I’ll try to flush out more information about how the biomarkers work …
Meanwhile, here are some links for more general information …
