Scope

Emissions of naphthalene from three different types of moth repellents: ball, gel, paper

Definition

Data

Measured using head space and small chamber tests by a Korean laboratory. [1]

Causality

Unit

mg/h

Formula

Failed to parse (Missing <code>texvc</code> executable. Please see math/README to configure.): EF = Q X (Ct-Co)/W

EF = emission fator (mg/(g*h))

Q = air flow rate (m^3/h)

Ct = equilibrium concentration (mg/m^3)

Co = background concentration (mg/m^3)

W = mass

ER = EF*W

ER = emission rate (mgh)


Result

Product ACH Emission rate Emission factor
h-1 mg/h mg/(g\*h)
ball 0.5 6.292 0.1924
1 5.847 0.1794
2 5.274 0.1628
gel 1 0.056 0.0017
paper 1 0.008 0.0014
