    Abstract : Rapid economic development has occurred during the past few decades in China with the Yangtze River Delta (YRD) area as one of the most progressive areas. The urbanization, industrialization, agricultural and aquaculture activities result in extensive production and application of chemicals. READ MORE

  4. 12. On the combustion and photolytic degradation products of some brominated flame retardants

    Author : Gunilla Söderström; Stellan Marklund; Mats Tysklind; Kees Olie; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; PBCDD; PBCDF; PBDD; PBDF; PBDE; HBCD; TBBP-A; combustion; photolytic; MSW; Miljökemi; Environmental chemistry; Miljökemi;

    Abstract : Many modern products, especially electronic goods, are protected by brominated flame retardants (BFR). Some of the most common flame retardants are polybrominated diphenylethers (PBDE), tetrabromobisphenol-A (TBBP-A) and hexabromocyclododecane (HBCD). READ MORE

  5. 13. Leaching and Transformation of Flame Retardants and Plasticizers under Simulated Landfill Conditions

    Abstract : About 600 children and teenagers work at Managua's landfill, the largest in Nicaragua. They collect and sort waste at the open dump, which covers an area of 7 km2 on the outskirts of the city on the shores of Lake Managua. READ MORE

  7. 15. The rotating injector as a tool for exploring DI diesel combustion and emissions formation processes

    Author : Magnus Sjöberg; KTH; []
    Keywords : diesel spray combusion; rotating injector. Air swirl; air fuel-mixing. Soot. NO. CO; flame visualization. Chemking modeling. Soot deposition;

    Abstract : A diesel fuel injector has been modified to allow rotationaround its axis, driven by an electric motor. Injections at upto 6000 rpm from the rotating injector have been investigatedunder the influence of air swirl on one optical research engineand one optically accessible heavy-duty diesel engine.
