Manual or automated measuring of antipsychotics' chemical oxygen demand [PDF]

open access: yesEcotoxicology and Environmental Safety, 2018
Antipsychotic (AP) drugs are becoming accumulated in terrestrial and aqueous resources due to their actual consumption. Thus, the search of methods for assessing the contamination load of these drugs is mandatory. The COD is a key parameter used for monitoring water quality upon the assessment of the effect of polluting agents on the oxygen level. Thus,
