“…The chamber sides and top were bolted together so that the chambers could be disassembled for transportation into the field. 10 The chambers were placed over the vegetation to be fumigated and a blower was used to circulate air through each chamber at a rate of three air changes per minute. The pollutant concentration in the air circulating through the chamber was controlled by adding pollutants to the inflowing air through flowmeters from LPO tanks of 10 to 20% pollutant in nitrogen.…”

“…Por otra parte, es un compuesto químico extremadamente reactivo capaz de atacar gran número de materiales. Aun cuando estos aspectos ya justifican suficientemente su inclusión en un sistema de simulación del que se pretenden amplias aplicaciones, existe además el hecho de que su gran reactividad condiciona en gran medida el diseño del sistema de simulación, obligando a una cuidadosa selección de materiales de construcción y a un riguroso control de temperatura en determinadas partes de la instalación (2,3).…”

“…Hydrogen fluoride fumigations were generated by the method of Hill et al 12 Fluoride concentrations were monitored by absorbing HF in impingers containing 0.02 M KNO3 and determining the F~ concentrations of sequentially obtained samples with an Orion Model 401 F~ analyzer. 13 Fluoride uptake was determined by F~ analysis of the treated plant tissue.…”
