A worldwide survey of polychlorinated dibenzo - p - dioxins , dibenzofurans , and related contaminants in butter 二苯并呋喃以及相關(guān)污染物的世界性調(diào)查
Method for determination of tetra - through octachlorodibenzo - p - dioxins , tetra - through octachlorodibenzofurans and dioxin - like polychlorinatedbiphenyls in industrial water and waste water 工業(yè)水和廢水中4至8 -氯代二苯并-對(duì)二氧芑4至8 -氯代二苯并呋喃和類二氧芑的多氯聯(lián)苯并的含量測(cè)定方法
There were many growth factors taking part in the control and regulation of metabolism within the bone development . 2 , 3 , 7 , 8 - tetrachlorodibenzo - p - dioxin ( tcdd ) is a widely spread environmental contaminant with extremely toxic effect 在骨發(fā)育過(guò)程中,激素調(diào)節(jié)、生長(zhǎng)因子調(diào)節(jié)與神經(jīng)系統(tǒng)共同形成了神經(jīng)-內(nèi)分泌-免疫-局部生長(zhǎng)因子調(diào)節(jié)網(wǎng)絡(luò),參與骨發(fā)育的整個(gè)調(diào)節(jié)過(guò)程。
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 用高分辨率氣相色譜一高分辨率質(zhì)譜方法( hrgc一hrms )對(duì)表層沉積物( 7個(gè)) 、巖心沉積物( l個(gè))和貽貝( 2個(gè))中的多氯代二苯并二惡英/吠喃( pcdd / fs )進(jìn)行了探討。
