pcdd meaning in Chinese
氯代二苯并二英
Examples
- Except for the area near the haibo river mouth , the relative contributions of individual 2 , 3 , 7 , 8 - substituted congeners at each station were similar , the lower chlorinated congeners dominated over the higher chlorinated pcdd / fs
除河口处外， pcdd / fs同系物分布基本上相同，即低氯代pcdd / fs占主导。 pcdd / fs总量的垂直变化趋势是从1951年到现在逐渐增大。 - Polychlorinated dibenzo - p - dioxins and dibenzofurans ( pcdd / fs ) in surface sediments at 7 stations , 1 sediment core and 2 mussels from qingdao coastal sea were analyzed using hrgg - hrms . the highest level was an order of magnitude higher than at other stations . the horizontal distribution of the total 2 , 3 , 7 , 8 - substituted pcdd / fs in the sediments formed an east - west pattern
用高分辨率气相色谱一高分辨率质谱方法( hrgc一hrms )对表层沉积物( 7个) 、岩心沉积物( l个)和贻贝( 2个)中的多氯代二苯并二恶英/吠喃( pcdd / fs )进行了探讨。 - Since 1951 , the total fluxes of cdd / fs in the qingdao coastal sea have increased steadily . the total teqs ( teq ) fluxes decreased in 1980 and then increased again , exceeding all the levels before . except for the area near the river mouth , the source of pcdd / fs at other stations was believed to be the atmospheric deposition from long - range transport
Pcdd / pcdf比值和ocdd占总p4 . scdd / fs的百分比ocdd ( %艺)表明青岛近海pcdd / fs的来源相对恒定，除河口处受河流输入影响之外，其它海区的pcdd / fs来源均可认为是由大气输入。
