Opis:
The bubbling behaviour originating from the combustion of pyrotechnic mixtures of KClO4/Mg-50%Al alloy, and with additives such as nitrocellulose (NC) and urotropine, were studied by high speed photography. The results revealed that with the addition of the additives the combustion pressure and the gas flow rates increased in the order KClO4/Mg-50%Al/NC (3) > KClO4/Mg-50%Al/urotropine (2) > KClO4/Mg-50%Al (1). Additionally, it is confirmed that the bubbling phenomena can be classified into various stages, i.e. single bubbling, pairing and single coalescence, double coalescence and so on.

Opis:
Pine needles and foodstuffs collected from Beijing, China, were analyzed by instrumental neutron activation analysis (INAA) combined with organic solvent extraction for total halogens, extractable organohalogens (EOX) and extractable persistent organohalogens (EPOX). The INAA detection limits are 50 ng, 8 ng and 3.5 ng for Cl, Br and I, respectively. The contents and distribution patterns of organohalogens in these samples are reported. EOCl accounted for 0.013 0.016% and 1.6 2.7% of the total chlorine in yogurt and apples, respectively, which suggested that chlorine in foodstuffs mainly existed as inorganic species and non-extractable organochlorines. EOCl contents in pine needles and foodstuffs were noticeably higher than those of EOBr and EOI. For pine needles, yogurt and apples, 1.6 34%, 23 58% and 29 35% of EOCl remained as extractable persistent organochlorine (EPOCl), respectively. Pine needle containing higher EOCl contents in chemical industrial and traffic hub areas indicated that chemical industries and exhaust emission from vehicle were the main sources of organochlorines in the Beijing's air. The relative proportions of the known organochlorines (such as HCHs, DDTs, chlordanes, heptachlor, HCB and PCBs) to the total EOCl and EPOCl were 0.04 1.6% and 0.7 21.5%, respectively, which implied that the identity of species of a major portion of the EOCl and EPOCl measured in pine needles was unknown.
