Characterization of Antibiotics and Antibiotic Resistance Genes on an Ecological Farm System

Table 2

Potential risk values (HQ) of antibiotics on the soil bacterial community.

Antibiotics	PNECs^a; (μg kg^−1)	Feces		Biogas slurry		Soils
		Fresh	Dried	Effluent	Solid
SMX	270
TC	270
OTC	50
CTC	53	5.58	0.51	15.20	6.83	2.45

PNECs were used as described by Li et al. (2013) [12].
