As phosphine fumigation concentration increased, the residual concentration of phosphine also increased in the hams (P < 0.05), but all samples contained levels that are lower than the legal limit of phosphine allowed in stored food products (0.01 ppm) in the United States.
Fluoride and SF concentrations increased (P < 0.05) in dry cured hams as SF fumigation concentration increased, but all samples contained fluoride and SF concentrations below the legal limits of 20 and 0.01 ppm, respectively.
In separate experiments, randomized complete block designs with three replications were utilized to evaluate the effects of phosphine (PH3) (0, 200 and 1000 ppm for 48 h) and methyl bromide (MB) (0, 4, 8, 16, and 32 mg/L for 48 h) fumigation concentration on the volatile flavor compound concentrations in dry cured ham.
A randomized complete block design with three replications was utilized to evaluate the effects (P < 0.05) of various fumigation concentrations of sulfuryl fluoride (SF) (0, 12, 24, 36 and 72 mg/L) on the fluoride, sulfuryl fluoride, and volatile flavor compound concentrations in dry cured ham.
Hydrogen cyanide, or formonitrile, HCN, is a highly volatile and extremely poisonous gas that is used in fumigation, ore concentration, and various other industrial processes.
Results indicated a significant effect of ethanol fumigation on the concentration of the emitted particles but not on the average size, as well as, a negligible impact of ethanol premixed charge on the soot nanostructural features.
The concentration of β-carotene after fumigation reached levels (10 40 mg g Fw−1) previously reported by Singh et al. [ 17].
Thermal internal boundary layer (TIBL) in onshore wind has a significant influence on dispersion of air pollutants and causes fumigation which brings high ground level concentration (GLC) of pollutants.
The serum fluoride concentration of the wife six days after the fumigation was reported to be as high as 0.5 mg/L [ 189].
Fumigation had no effect on the concentration of tocopherol (Fig. 1c), and it was in accordance with previously reported results [ 17, 18].
Semi-quantitative RT-PCR analyses at least in triplicates were performed to assess the transcript regulation of selected genes in leaves 6 h after fumigation beginning with the respective CO2 concentration (Fig. 3).
