查询词典 threshold exposure

EROD and ECOD are both phase I enzymes. There were complicated relations of time-effect and dose-effect between EROD activity and exposure of BaP, TBT or their mixture. Antagonistic interactions occurred after 25 days exposure to the mixure of BaP and TBT. It is fuzzy to merely use EROD activity as biomarker to assess PAHs or TBT pollution.

相解毒酶EROD活性与BaP、TBT及其混合物污染之间存在较为复杂的时间-效应与剂量-效应关系，而且在暴露25 d后，联合作用表现为拮抗作用，仅仅以EROD酶活性指标衡量环境中BaP、TBT或者二者的联合污染水平会出现失真现象。

The objective of the risk characterization step is to integrate all of the information from the first three steps and provide both a qualitative assessment of the potential human health impact from exposure to the parasitic hazard and a quantitative estimate (e.g., 1:10, 1:10,000, 3:100) of the probability of certain human health outcomes actually occurring due to that exposure.

这一目标的风险特性的步骤是把所有的资料，前三个步骤，并提供一种既定性评估的人类健康的潜在影响，接触到寄生虫危害和定量估算（例如， 1：10 ， 1：1万， 3：100 ）的概率某些人类健康的结果实际发生的因接触。

Based on the four steps of risk assessment that is hazard identification,hazard characterization,exposure assessment and risk characterization,the risk assessment of bisphenol A is expound in this paper.The results show the potential human exposure to bisphenol A is negligibl...

根据风险评估理论的四个步骤，即危害鉴定、危害特征描述、暴露评估和风险特征描述，对双酚A进行风险评估，结果表明人体暴露于双酚A的量是微不足道的，没有对人体健康构成已知的风险。

Pearl ornaments should avoid exposure to acid-alkali substances and high temperature. they should also avoid direct exposure to perfume, hair crem and oil and salt, etc.when you wash your face and take a bath, you should take them off.

珍珠首饰应避免与酸碱性物质及高温接触，也应避免与香水、发乳及油盐等直接接触，洗脸、洗澡时应取下，珍珠沾有汗水和污物时，用中性洗涤液稍加浸洗，用水冲净。

The xinguang tube time-sensitive, relatively short exposure time, relatively small light permeability to expand; however, as the UV light to rule over the ages, lighting effects, exposure time gradually extended, fine idea is not easy, but deep PIP light permeability to expand it is becoming increasingly damageto, resulting in a traditional version that are the same pair of film on the same printer, after a certain period of time, get the flexo from deep network to a brief network halftoning, also occur when different curves change!

这表示在新平惯时平敏不弱，曝平工夫相差长，平渗放大相差小；但随着UV平惯的忽然老化，平效放松，曝平工夫忽然延不幼，粗不面子不便当不入来，但浅不面子的平渗放大愈发狠恶，酿成古板版那怕是统一副胶片在统一台晒版机上，经过一段期间后，晒不入的刚性版从浅网到浅网的阶调，也会爆发差别的弧线改变！

These two elaborate laboratories, ventilation/fire protection laboratory and exposure chamber, can be simulated as the occupational workplace. Students will have opportunities to gain the practical discipline within campus, such as fire scene examination, fire fighting tool use, fire protection system establishment, and exposure assessment etc. Three curricula have been compiled as a guide to assist students to get more understanding on the hazard identification within campus.

本校是全国唯一同时设有消防实习教室及暴露舱实习教室的学校，可模拟火灾发生时之情景，进行水雾系统操作、各种灭火工具使用、防火系统设置等实习教学活动，学生并可利用暴露舱室进行暴露空气中危害物质之体验教学，更能加深学生了解空气品质对健康危害之认知，同时在使用个人防护具的教学中，学生能有实作的机会，这是本教学方案最大的特色。
