Study of the volatilization inhibitor for formalin / 中华劳动卫生职业病杂志

<p><b>OBJECTIVE</b>To find an inhibitor to reduce the volatilization of formalin.</p><p><b>METHOD</b>The saturated solution of sodium hydrosulphite (SHS) was sprayed on the surface of the anatomy specimens, then the concentration of formaldehyde in the air was tested.</p><p><b>RESULTS</b>The concentration of formaldehyde in the air of SHS sprayed group [(3.10 +/- 1.22) mg/m3] was significantly lower than that of the control group [(8.36 +/- 4.11) mg/m3, P < 0.01].</p><p><b>CONCLUSION</b>SHS may be a volatilization inhibitor for formalin, which could reduce the concentration of formaldehyde in the air.</p>
