Leading doctors today weigh in on the debate over the governments role in promoting public health by demanding that ministers impose "fat taxes" on unhealthy food and introduce cigarette-style warnings to children about the dangers of a poor did.

The demands follow comments made last week by the health secretary, Andrew Lansley, who insisted that government could not force people to make healthy choices and promised to free businesses from public health regulations.

But senior medical figures want to stop fast-food outlets opening near schools, restrict advertising of products high in fat, salt or sugar, and limit sponsorship of sports events by fast-food producers such as McDonald's.

They argue that government action is necessary to curb Britains addiction to unhealthy food and help halt spiraling rates of obesity, diabetes and heart disease. Professor Terence Stephenson, president of the Royal College of Paediatrics and Child Health, said that the consumption of unhealthy food should be seen to be just as damaging as smoking or excessive drinking.

"Thirty years ago, it would have been inconceivable to have imagined a ban on smoking in the workplace or in pubs, and yet that is what we have now. Arc we willing to be just as courageous in respect of obesity? I would suggest that we should be. said the leader of (he UK' s childrens doctors.

Lansley has alarmed health campaigners by suggesting he wants industry rather than government to take the lead. He said that manufacturers of crisps and candies could play a central role in the Change 4Life campaign, the centrepiece of government efforts to boost healthy eating and fitness. He has also criticized the celebrity chef Jamie Oliver s high-profile attempt to improve school lunches in England as an example of how lecturing people was not the best way to change their behaviour.

Stephenson suggested potential restrictions could include banning TV advertisements for foods high in fat, salt or sugar before 9 pm and limiting them on billboards or in cinemas. If we were really bold, we might even begin to think of high-calorie fast food in the same way as cigarettes--by setting strict limits on advertising, product placement and sponsorship of sports events. he said.

Such a move could affect firms such as McDonald s, which sponsors the youth coaching scheme run by the Football Association. Fast-food chains should also stop offering "inducements such as toys, cute animals and mobile phone credit to lure young customers, Stephenson said.

Professor Dinesh Bhugra, president of the Royal College of Psychiatrists, said: "If children are taught about the impact that food has on their growth, and that some things can harm, at least information is available up front.

He also urged councils to impose "fast-food -free zones" around schools and hospitals-areas within which takeaways cannot open.

A Department of Health spokesperson said: We need to create a new vision for public health where all of society works together to get healthy and live longer. This includes creating a new responsibility deal with business, built on social responsibility, not state regulation. Later this year, we will publish a white paper setting out exactly how we will achieve this.

The food industry will be alarmed that such senior doctors back such radical moves especially the call to use some of the tough tactics that have been deployed against smoking over the last decade.

【背景资料】
某建设工程公司承担了一矿井的施工工作。该矿井采用立井开拓方式,中央边界式通风,井田中央布置了2个井筒、主井井筒净直径5.5m,井深650m;副井井筒直径7.0m,井深625m;风井位于井田东北部边界,净直径5.0m,井深515m。
施工单位在矿井开工前,组织编制了该矿井的施工组织设计,确定了矿井的施工方案,明确了施工准备工作的具体内容,并进行了认真准备。考虑到井筒表土较薄,又没有流沙,采用普通法进行施工:基岩部分采用钻眼爆破法施工:主、副井到底后进行短路贯通,然而主井由于出水淹井,施工进度缓慢,副井先到底,矿井整个施工组织被打乱。
在矿井进入三期工程时,由于部分工程滞后,排水系统管路刚开始铺设,中央水仓刚施工完成;矿井的两回路电源线路取自一个区域变电所同一母线;掘进工作面仅安设了压风管路和通信线路就匆忙施工掘进。
