This is their point of maximum concentration 對我們來說,這是最好的方法了。
Maximum concentration of certain substances present in specified foods 指明食物所含某些物質(zhì)的最高濃度
You approach them with the maximum concentration , knowing that you risk everything in the space of a week 隊長:注意力高度集中接近他們,知道在這一個星期的時間里很多事情都有風(fēng)險。
It is found that the maximum concentrations of the species change with the decrease of height , rising and dropping drastically in the transition region 實驗表明,煙氣毒性成分的濃度峰值隨高度的降低呈現(xiàn)明顯的階梯變化,在過渡區(qū)段驟升驟降。
These parameters influence the maximum ( peak ) concentration , the time at which the maximum concentration occurs ( peak time ) , and the area under the concentration - time curve ( auc ) after a single oral dose 這些參數(shù)會影響單劑口服后的最大(峰)濃度,到達最大濃度的時間以及濃度-時間曲線下面積。
In conjunction with the final phase implementation of the public health ( animals and birds ) ( chemical residues ) regulation , controls under the harmful substances in food regulations will concurrently be extended to the remaining 18 chemicals , with the same prescribed maximum concentration levels in meat , offal and milk 為配合《公眾?生(動物及禽鳥) (化學(xué)物殘馀)規(guī)例》的最后階段管制, 《食物內(nèi)有害物質(zhì)規(guī)例》亦由明日開始,管制馀下十八種化學(xué)物在肉類、內(nèi)臟及奶內(nèi)的最高殘馀限量。
To tie in with the second phase implementation of the public health ( animals and birds ) ( chemical residues ) regulation , we will concurrently extend control under the harmful substances in food regulations to the same nine additional chemicals prescribed with the same maximum concentrations levels in meat , offal and milk 為配合《公眾?生(動物及禽鳥) (化學(xué)物殘馀)規(guī)例》的第二階段管制, 《食物內(nèi)有害物質(zhì)規(guī)例》亦由明日開始,管制這九種化學(xué)物在肉類、內(nèi)臟及奶內(nèi)的最高殘馀限量。
The results show that the majority of 7be is retained in the top one centimeter of soils , and the concentration of 7be decreases exponentially with soil depth . for the cultivated study field , the depth distribution of 7be is very similar to the undisturbed site when it is n ' t subjected to erosion or deposition . for the undisturbed , there is abroad peak in the 137cs profile close to the surface and the maximum concentration is found circa 2 cm below the surface ~ ( 137 ) cs在未擾動土壤剖面中主要分布在0 5cm范圍內(nèi),同時在1 3cm的范圍出現(xiàn)一個~ ( 137 ) cs的相對富集層,在3cm以下隨土壤深度的增加呈指數(shù)遞減的趨勢; ~ ( 137 ) cs在農(nóng)耕地土壤剖面中主要分布在0 20cm范圍內(nèi),由于耕作活動的不斷擾動~ ( 137 ) cs的剖面分布相對均勻。
The human body has developed to deal with low levels of many naturally toxic substances and thus experts assessing risk will not only be investigating the effect of large doses of the contaminant on human health , but also investigating if there is a safe maximum concentration level of the contaminant which has no adverse effect on human health 人體已經(jīng)進化到能夠處理少量天然存在的有毒物質(zhì),因此專家們在研究某種物質(zhì)的危害性的時候,不僅要研究大劑量攝入對機體健康的損害,還要研究是否存在一個最大安全限量,在這個限量以下就不對機體發(fā)生有害作用。
