Firstly, by means of interelement correction, multi-wavelengths, two-point correction, and SPE online flow-injection adsorption method etc., background shift and spectra overlap caused by matrix effect, ambient ion interferences, emission of non-analytes in ICP-OES analysis were eliminated. Secondly, in order to overcome the interferences from PCB, PCN, HCB in the process of determination of PBBs/PBDEs, a matrix solid-phase dispersion method with YMC ODS-C18 as carrier was employed, which completely removed the negative influences of the persistent organic pollutants. Thirdly, by combining GC-NICI-MS with GC-EI-MS, brominated isomers or ramifications were distinguished from other halogen compounds in which anion fragment retention peaks of -, [HBr2]- and molecule chain fragment peaks of [M+2]+, [M+4]+, [M+6]+, [M+8]+ were observed simultaneously, and thus the selectivity to brominated retardant flames was greatly improved. Besides, effects of sample shape, thickness, screening area and screening time etc. on X-ray emission intensities of analytes during EDXRF screening were discussed, and in order to eliminate secondary excitation of analytes, absorption, X-ray dispersion of coexisting ions etc., a parameter simulation regression analysis was established, the results showed that a satisfactory function curve between emission intensities and concentration of analytes was obtained. The above means can improve the precision and reliability on the determinations of six hazardous substances.
