Occurrence of Antibiotics and Antibiotic-Resistant Bacteria in Landfill Sites in Kumasi, Ghana

Table 2

A summary of retention time, method LOD, LOQ, LR, and SPE recoveries of antibiotics from leachate and soil samples.

Antibiotic	Retention time (min)	Linear range (μg/mL)	LOD (μg/mL)	LOQ (μg/mL)	SPE recovery efficiency (%) (leachate)
Amoxicillin	7.815	6.25–200	0.097	0.295	37.92 ± 1.591
Metronidazole	6.460	6.25–200	0.003	0.010	97.86 ± 10.886
Penicillin	12.094	6.25–200	1.565	4.740	92.96 ± 5.908

LR, linear range; LOD, limit of detection; LOQ, limit of quantitation; SPE, solid phase extraction.
