Phosphate flame retardants (PFRs) are abundant and found at the highest concentrations relative to other flame retardant chemicals in house dust; however, little is known about the biological levels of PFRs and their relationship with house dust concentrations.
Abundant combustion intermediates present during flame synthesis of these materials partially reduce TiO2 and induce strong metal support interactions (SMSI) resulting in crystalline Ti-suboxides as determined by X-ray diffraction.
On the other hand, for C3H8 flames, naphthalene is the most abundant compound in the range of smaller Zst while acenaphthylene is abundant under larger Zst conditions.
Phthalates and flame retardants are particularly abundant; DEHP, BBP, PBDE 99, PBDE 47, and DBP were the five chemicals with the highest concentrations at the 95th percentile.
Flame robins often become more abundant in areas recently burnt by bushfires, but move away once the undergrowth regrows.
Naphthalene is the most abundant compound under all experimental conditions in CH4 flames.
As is well known, GO exhibits an extremely low thermal stability and easily combusts in air atmosphere owing to abundant oxygen-containing groups, severely restricting its application as flame retardants.
Ammonium sulfate, which is the most abundant salt in the treatment mixture, is a well-known flame retardant [38, 39].
Xerochrysum 'Nullarbor Flame' was a selection introduced into cultivation in 1997 that produces abundant red flowers with yellow discs and a diameter of 4.5 cm (1.8 in).
Benzene was the most abundant aromatic species with the peak level of 450 ppm, whereas naphthalene (90 ppm), phenanthrene (10 ppm), pyrene (35 ppm), and cyclopenta(cd pyrene (23 ppm) were the most abundant PAHs formed in the flame.
