TABLE 1.

D₁₀ values of human adenovirus, individually or pooled, in different substrates

Substrate	COD (mg O2/liter)	D10 values (HAdV-5) ± standard error (kGy)a
Phosphate-saline buffer, pH 7.2	<50	0.9 ± 0.1 A
Deionized filtered water, pH 8.0	<50	0.9 ± 0.1 AB
Tap water, pH 7.6	<50	1.0 ± 0.1 AB
Tap water + 105 PFU/ml of MNV-1	NDb	0.8 ± 0.1 A
Wastewater, pH 5.8	76	1.3 ± 0.1 BC
Wastewater + 105 PFU/ml of MNV-1	ND	1.6 ± 0.1 C
100% FBS, pH 7.7	60,532	2.9 ± 0.2 D
100% FBS + 105 PFU/ml of MNV-1	ND	2.9 ± 0.1 D
10% FBS	ND	3.2 ± 0.2 D
50% FBS	ND	3.6 ± 0.1 D

^aThe D₁₀ values that have the same letter are not considered significantly different (P < 0.05).

^bND, not determined.
