Adverse effects induced by ecgonine methyl ester to the zebra mussel: A comparison with the benzoylecgonine

, 2013
Cocaine and its metabolites are the prevalent psychotropic substances in aquatic environment. However, to date the knowledge on their adverse effects to non-target organisms is inadequate.

"Trace" Benzoylecgonine Identifications in Post- Race Urines: Probable Sources and Regulatory Significance of Such Identifications

, 2020
Cocaine is an environmental contaminant in North America. Benzoylecgonine (BZE) is the major urinary metabolite of cocaine in horses and humans, and urinary detection of BZE is highly sensitive. Human workplace drug testing typically uses a confirmatory &

First evidence of protein profile alteration due to the main cocaine metabolite (benzoylecgonine) in a freshwater biological model

, 2013
Illicit drugs represent not only a great social problem but are also considered an environmental problem because their use and, often, abuse release large amounts of parent compounds, and especially their metabolites, into freshwaters.

The Distribution of opiates, cocaine and their metabolites in skeletal muscle tissue and vitreous humour as an aid to post-mortem toxicological interpretation.

Post-mortem blood drug concentrations vary greatly and as a consequence of post-mortem change and redistribution may not reflect the concentration at the time of death.
