什么是总量控制规划?现拟进行某地区大气环境总量控制规划,应如何进行?

答案

参考答案:

就是依据某一区域的环境容量确定该区域内污染物容许排放总量,再按照一定原则分配给区域内的各个污染源,同时制定出一系列政策和措施,以保证区域内污染物排放总量不超过区域容许排放总量的规划方法。

要搞好某地区大气环境进行总量控制规划,主要要做好如下工作:

一是合理地确定污染浓度计算模式;

二是确定对象区域范围、污染物种类、环境目标及其实现年限;

三是采用“网格法”进行模拟计算;

四是掌握烟源、气象及大气污染现状资料,进行分析整理;

五是对将来污染浓度的预测;

六是计算环境总量与各污染源的容许排放指标。

单项选择题

Do you think there is too much noise in our city If you live near an airport, you will be unhappy because a plane often makes a loud noise. The sound of planes or heavy vehicles is likely to cause deafness if heard continuously.
However, most people in our city do not seem to mind noise. They like to enjoy music when they are doing uninteresting jobs. It is a new danger because pop music, when played through powerful amplifiers, can reach 120 decibels at a distance of five feet. A continuous noise of over 85 decibels can cause deafness. It was discovered that many young people in America could hear no better than 65-year-old people.
In the past we used to think that only workers in very noisy places would become deaf. For example, when newspapers and books are being printed, the noise level is over 85 decibels, and some of the workers become deaf. Today, however, scientists believe that 10 percent of the workers in Britain are being deafened by the noise.
Sometimes noise of less than 85 decibels can make some people tired and stressed. We all know that too much noise makes life difficult and unpleasant. It can do great harm to people’s health and prevent people from working well. Workers in noisy offices are not as efficient as those in quiet offices. Noise makes people less efficient. Can anything be done to reduce or control noise
In Britain the government has made several laws to reduce noise. Though the government has spent a lot of money in making airports and main roads quieter, many people think that there are still not enough laws. For example, there are no laws to control the noise of machines. In Japan, America and Norway there are such laws. As a result, workers can be given compensation if they become deaf.

Noise below the level of 85 decibels ______.

A.can affect some people’s moods

B.cannot do any harm

C.can cause sudden deafness

D.can make office workers efficient
