c = cost coefficient per ppm reduction in HCHO emissions,
The lower the operating target for HCHO emissions, given no reduction in HCHO variation, the higher the cost, e.
Effect of supports on the gold catalyst activity for catalytic combustion of CO and HCHO.
HCHO was generated by passing a purified air flow over HCHO solution; flow through reactor: 50 mL/min (0.
La produccion de radicales por fotolisis del HCHO (estimada en ~0,17ppbv*[h.

2]S, and HCHO
, we created dichotomous exposure variables defined as quantified gas concentrations versus gas concentrations below the limit of quantification.
Two types of concentration-decay tests, identical to JIS C 9615 and JEM 1467, were carried out as performance tests for the removal of chemical substances, such as HCHO
2005), queda claro que la fuente principal de HCHO
en la region es la oxidacion del isopreno, el cual es emitido por la vegetacion.
