| 1. | Modification of rinsing techniques by installing cascading or counter-current rinse systems increases the contaminant concentration .
安装了阶梯式装置或对流漂洗装置，可改进漂洗技术，把污染物的浓度提高。 |
| 2. | Since a chief source of pollutants is automobile emissions, it might be expected that pollutant levels could be correlated with automobile traffic, at least to some extent .
因为污染物的主要来源是汽车的排出物，所以可以料想污染物的浓度至少在某种程度上是与汽车运输有关。 |
| 3. | " however , the concentrations do vary due to different local conditions , such as traffic , meteorology , building layout , and configuration .
“然而，污染物的浓度却因当地诸如交通气象建筑物布局及结构等不同情况而有所变化。 ” |
| 4. | In fact , it is not always the truth . because of bad ventilation and synthetic material , the concentrations of air contaminations indoors are even higher than that outdoors
由于不良通风和大量化学合成剂在建筑材料中的使用，使得室内空气污染物的浓度有时要高于室外。 |
| 5. | Because bad ventilation and a large amount of synthetic material used in the construction material , the concentration of air contaminations indoors are often higher than the outdoors
由于不良通风和大量化学合成剂在建筑材料中的使用，使得室内空气污染物的浓度常常高于室外。 |
| 6. | We present a methodology for computing daily pollutant concentration fields that reduces exposure uncertainty and bias by taking account of spatial variation in air quality
我们呈现一个方法来计算每天污染物的浓度，以减少在考虑空气品质的空间变异性时，对于暴露的不确定性及偏差。 |
| 7. | Describe the local , regional , national or global condition of the environment as a result of your department bureau s contribution i . e . environmental condition indicators , e . g . area rehabilitated in a defined local area , concentration of a specific contaminant in a water body
说明部门政策局对本地地区全国或国际环境所作的贡献即环境情况参数，例如区内个别指定范围内修复的地方水域内个别污染物的浓度 |
| 8. | According to the relationship between organic pollutants concentration in river water environment and the influential factors , a rbf model has been used to applied to prediction of organic pollutant concentration of water environment based on the field observation data
根据河流有机污染物的浓度与其影响因素之间存在的映射关系，以实际监测数据为基础，建立了一个水环境有机污染物浓度预测的径向基函数网络模型。 |
| 9. | Apart from the concentrations and chemical properties of the pollutants , the person s age and general state of health , the duration of exposure , factors such as the weather condition and the distance from the emission sources also affect the nature and extent of the health effects observed
除了空气中污染物的浓度与化学特性之外，有关人士的年与一般健康状况接触污染物的时间长短气候情况以及排放源头与接触者之间的距离等，都会对健康构成不同的影响。 |
| 10. | Apart from the concentrations and chemical properties of the pollutants , the person s age and general state of health , the duration of exposure , factors such as the weather condition and the distance from the emission sources also affect the nature and extent of the health effects observed
除了空气中污染物的浓度与化学特性之外，有关人士的年龄与一般健康状况、接触污染物的时间长短、气候情况以及排放源头与接触者之间的距离等，都会对健康构成不同的影响。 |
