Active Carbon Respiratory Masks as the Adsorbent of Toxic Gases in Ambient Air

Table 2

Effectiveness of the use of masks and exposure to SOx.

		n	Mean	CI 95%
				Min	Max
SOx not Adsorbed	Control	7	0.88	0.6	1,08	≤0.001
	Cotton	7	0.84	0.13	0.27
	Spunbond & Meltblown	7	0.44	006	0.18

One-way ANOVA, α = 5%.
Significant (p ≤ 0,05).
Post hoc LSD: control vs cotton: P = 0.10; control vs spunbond & meltblown: P-“0,001; control vs combination active carbon, spunbond & meltblown: P = 0,01; cotton vs spunbond & meltblown: P = 0,01; cotton vs combination active carbon, spunbond & meltblown: P = 0,01; spunbond & meltblown vs combination active carbon, spunbond & meltblown: P-“ 0,001.
