Determination of personal care products and pharmaceuticals in river sediments, KwaZulu-Natal,

South Africa

Bhekumuzi Gumbi

University of KwaZulu-Natal, Durban, South Africa

A

quantitative method is described for ultrasonic-assisted solid-phase extraction (SPE) followed by GC-MS after

derivatization for the simultaneous analysis of personal care products and pharmaceuticals (PCPPs); propyl paraben,

triclosan, caffeine, carbamazepine and chloramphenicol. Ultrasonic combined with centrifuge were used to extracts sediments

samples collected from Mgeni and Msunduzi River. An SPE procedure was used for clean-up and to concentrate selected

compounds from diluted aqueous extracts. Final extracts were derivatized with BSTFA and analyzed with GC-MS in selected

ion monitoring (SIM) mode. The recoveries of the analytes ranged from 66% to 108%. The method detection limits were 0.08–

1.82ngg-1 and quantification limits 0.42–5.51ngg-1. The proposedmethod was applied in the evaluation of two rivers over three

month period in KwaZulu-Natal, South Africa. All targeted compounds were present in the environment at concentration level

between not detected to 174ngg-1. To our knowledge, this is a first report on the simultaneous determination these PCPPs by

GC-MS in Africa.
