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 (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle 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 |
