Occurrence of Pharmaceutical Residues and Antibiotic-Resistant Bacteria in Water and Sediments from Major Reservoirs (Owabi and Barekese Dams) in Ghana

Table 2

Occurrence of pharmaceutical residues in water and sediment samples from Barekese.

Reservoir	Sample type	Pharmaceutical	Range		Frequency of detection (%)
Barekese		Amoxicillin	0.08–1.86		11.11
		Chloramphenicol	0.10–0.85		55.56
	Water (μg/L)	Diclofenac	0.03–4.36		11.11
		Metronidazole	0.06–22.23		11.11
		Paracetamol	0.06–0.16		11.11
	Sediment (μg/kg)	Chloramphenicol	2.78–10.22		80.00
Owabi		Amoxicillin	0.10–0.37		33.3
	Water (μg/L)	Chloramphenicol	0.18–0.53		77.8
		Diclofenac	0.69–107.89		33.3
		Paracetamol	0.01–0.15		33.3
	Sediment (μg/kg)	Paracetamol	0.10–6.54		66.67

Frequency of detection was computed by evaluating the ratio of the number of samples in which an analyte was detected to the total number of samples analyzed.
