揭秘“闻臭师”:考试要辨五味 鼻子太灵也不行

2016-09-03 08:02:27   齐鲁晚报

“考试考核的时候,会把这五种稀释之后的气味涂抹在试纸上,从五个试纸中闻出两个带有味道的试纸。这五种味道里,就数甜锅巴气味最难分辨,很多人都分辨不出甜锅巴的味道。”嗅辨员谷树茂说。理论考试和嗅觉检测合格的,如果没有特殊情况,可连续三年承担嗅辨员工作。

在实际的嗅辨工作中,更是有着一套标准的工作程序。谷树茂介绍:“整个嗅辨分为四个步骤,第一步就是采集样本样品,然后在实验室中配气、嗅辨,最后进行判定,通过公式计算出异味是否超标。”据介绍,每次嗅辨任务都需要八个人:一个配气员,六个嗅辨员,还有一个判定师,都需要有嗅辨员资格证书的人担任。

恶臭污染物20万种

仪器只能分析一部分

整个省环境监测中心站中,只有恶臭实验室的分析不是依靠仪器,而是依靠人。

在我国,常用的恶臭监测方法有仪器测定法和嗅觉测定法。仪器测定法是用仪器进行恶臭物质测定,确定臭气物质的成分与浓度,这种方法一般适用于判断污染物质的来源,但是对于综合性的异味浓度就束手无策了。

嗅觉测定法就是根据人的嗅觉来评价气味强度和适与不适的方法,用这种方法来测定恶臭的特征参数。依靠人的鼻子来分辨出恶臭气体对人们的影响程度到底有多大,以人的直观感受作为评判的依据。

恶臭污染物有20多万种,一般仪器分析只能分析一种或多种特定的气体,恶臭污染物会对人的嗅觉形成刺激,仪器并不能完全检测出这种污染程度。而人的这种分析则可以较准确地反映恶臭气体对于整个环境的污染程度,以及这种污染对人的嗅觉的影响程度。

其实,嗅辨员的鼻子并不像别人想象的那样有着超级灵敏的嗅觉,嗅辨员也是普通人。“鼻子不灵肯定成不了嗅辨员,鼻子太灵了也成不了嗅辨员。”由希华说,“嗅辨员的嗅觉不能太灵敏,要能代表普通大众的嗅觉感知,嗅觉太灵敏反而不能真实客观地反映臭气的浓度。”

拿事业单位工资

并没有额外补贴

据介绍,为了保持嗅辨的客观性,情绪不稳定的嗅辨员不能参加当天的测定嗅辨。在嗅辨开始30分钟之前或嗅辨过程中不能饮食,也不能食用口香糖或糖果。

嗅辨员必须在嗅辨测量开始前15分钟到达嗅辨区准备实验,以便适应嗅辨室的实际气味环境。其间还不得随意走动,以避免对检测结果造成误差。在嗅辨测量期间,参与嗅辨人员不得与其他人就选择嗅辨的结果进行交流。

很多恶臭气体都是有毒有害的物质,这些会对人体有不同程度的影响和危害,比如会引起呼吸道疾病等。由希华说,“为尽量减少恶臭气体对嗅辨员身体的影响,实验室通风条件进行了合理改造,配置了空气净化器,在嗅辨过程中对一些高浓度气体进行稀释,在嗅辨结束后让嗅辨员在通风条件较好的室外进行体内空气置换,并进行自我调整。”

不少人有疑问,既然嗅辨师的工作这么辛苦,那他们的工资应该很高吧?实则不然。据介绍,这些嗅辨员平时拿的只是普通事业单位的工资,并没有额外补贴。他们的工资一般按职称走,年轻点的三四千元,高级工程师也就五六千元。
