下列有关环境保护的说法错误的是(  )

A.含氮、磷化合物的生活污水大量排放可使水体富营养化

B.各国工业大量排放二氧化硫是全球气候变暖的主要原因

C.劣质装修材料中的甲醛、苯、氧气等对人体有害

D.废旧电池中的汞、镉、铅等重金属盐对土壤和水源会造成污染

答案

A、大量含氮、磷肥料的生产和使用,食品加工、畜产品加工等造成的工业废水和大量城市生活废水,特别是含磷洗涤剂产生的污水未经处理即行排放,使海水、湖水中富含氮、磷等植物营养物质,称为水体富营养化.故不符合题意.

B、全球变暖是指全球气温升高.致使全球气候变暖的人为影响主要包括两方面:一方面,人们在日常生产和生活中通过燃烧化学燃料释放大量的温室气体.近年来,主要温室气体的排放量不断增加,引起温室效应增强,使全球气候变暖;另一面,砍伐森林、耕地减少等土地利用方式的改变间接改变了大气中温室气体的浓度,也可使气候变暖.温室气体包括二氧化碳、甲烷、臭氧、氟利昂等,而二氧化硫不属于温室气体.故符合题意.

C、甲醛被确认为潜在强致癌、致畸物质,它对人的健康影响极大,对人的嗅觉有异常刺激性、易造成人皮肤过敏,肺、肝及免疫功能异常.苯属潜在致癌物质,在油漆、涂料等装修材料内都有苯.苯对儿童妇女危害尤大,可造成婴幼儿白血病.故不符合题意.

D、废旧电池的危害主要集中在其中所含的少量的重金属上,如铅、汞、镉等.这些有毒物质通过各种途径进入人体内,长期积蓄难以排除,损害神经系统、造血功能和骨骼,甚至可以致癌.经过长期磨损和腐蚀,使得内部的重金属和酸碱等泄露出来,进入土壤或水源,就会通过各种途径进入人的食物链.故不符合题意.

     A group of graduates, successful in their careers, got together to visit their old university professor.

Conversation soon turned into complaints about stress in work and life.  

Before offering his guests coffee, the professor went to the kitchen and returned with a large pot of

coffee and a variety of cups-porcelain, plastic, glass, crystal, some plain looking and cheap, some

exquisite and expensive-telling them to help themselves to the coffee.

     When all the students had a cup of coffee in hand, the professor said: "If you noticed, all the nice

looking expensive cups were taken up, leaving behind the plain and cheap ones. While it is normal for

you to want only the best for yourselves, that is the source of your problems and stress. Be assured

that the cup itself adds no quality to the coffee. In most cases it is just more expensive and in some

cases even hides what we drink. What all of you really wanted was coffee, not the cup, but you

consciously went for the best cups. . And then you began eyeing each other's cups.

     Now consider this: Life is the coffee; the jobs, money and position in society are the cups. They

are just tools to hold and contain Life, and the type of cup we have does not define, nor change the

quality of life we live. Sometimes, by concentrating only on the cup, we fail to enjoy the coffee God

has provided us. "

      God brews the coffee, not the cups. Enjoy your coffee!

     "The happiest people don't have the best of everything. They just make the best of everything. "

     Live simply. Love generously. Care deeply. Speak kindly. Leave the rest to God.
