1 sty 2021 · Over 85% of THC-COOH was removed from low initial concentration of less than 20 ng L −1 by FR and FLR (Mackuľak et al., 2015, 2016). THC-COOH was degraded by the highly reactive hydroxyl radical (• OH) that was generated in both FR and FLR.
Δ 9-tetrahydrocannabinol (THC), the major psychoactive component of cannabis, is rapidly metabolized to the inactive metabolite THCCOOH, conjugated with glucuronic acid, and excreted in urine. Fifteen to 20% of a THC dose is eliminated as acidic urinary metabolites .

1 sty 2021 · In particular, 11-nor-9-carboxy-Δ 9-tetrahydrocannabinol (THC-COOH) has been detected at concentrations up to 2590 and 169 ng L-1 in untreated and treated wastewater, respectively, 79.9 ng L-1 in surface water, and 1 ng L-1 in drinking water. High removal of cannabinoids has been observed in wastewater treatment plants; this is likely a result ...
1 mar 2014 · 11-Nor-9-carboxy-Δ 9-tetrahydrocannabinol (THC-COOH) is commonly selected as biomarker for the investigation of cannabis consumption through wastewater analysis. The removal efficiency of THC-COOH in wastewater treatment plants (WWTPs) has been reported to vary between 31% and 98%.
