《环境污染》PPT课件
• 直接危害 • 间接危害
急性危害
慢性危害
远期危害 温室效应 酸雨 臭氧层破坏 生物多样性锐减
环境污染物一次大量或24小时内多次接触机体后，在短 时间内使机体发生急剧的毒性损害甚至死亡。 （1）化学性污染：如1984年印度博帕尔化工厂的毒气泄漏事 件。 （2）生物性污染：常常引起人群中疾病的流行。介水传染病 如病毒性肝炎、伤寒、痢疾、霍乱等一旦发生，多以爆发的 形式出现，不仅影响生活及劳动能力，且严重威胁生命安全。
温室效应示意图
美国科学家得到的最新成果认为，如果人类不努力减 少温室效应，北极的冰川有可能到2040年时完全融化。
（2）形成酸雨
酸雨是指pH值小于5.6的酸性降水，其主要原因是 大气中SO2、NOX等污染物的含量过高，SO2、NOX溶于水 汽中，经过氧化、凝结形成酸雨。酸雨可使土壤酸化， 使重金属在土壤中的溶解性增加，有毒金属进入农作 物的量增加，从而导致人体摄入量增加。酸雨还可使 水体酸化，影响水生生物的生长，并影响水体的自净 能力。
第二节 环境污染及其对健康的影响
公共卫生学院 杨华
据统计，每砍伐一平方米的林，每年就有 0.4吨的泥沙流失。全世界每年有2500万儿童因饮 用受污染的水而生病致死。南极上空臭氧变薄的速 度达到每天损失1%，空洞的范围有如欧洲一样大小。 据美国环保署的有关研究，大气圈中臭氧含量每减 少1%，皮肤癌患者增加10万人，患白内障和呼吸道 疾病的人也将增多。据调查，我国有7亿人饮用大 肠杆菌超标水，1.64亿人饮用有机污染严重的水， 3500万人饮用硝酸盐超标水。
伦敦烟雾事件
1952年12月5日至8日，伦敦城市上空高压，大雾笼罩， 连日无风。而当时正值冬季大量燃煤取暖期，煤烟粉尘和 湿气积聚在大气中，使许多城市居民都感到呼吸困难、眼 睛刺痛，仅四日时间内死亡了4000多人， 45岁以上的死 亡最多，约为平时3倍； 1岁以下死亡的，约为平时2倍。 之后的两个月时间内，又有8000人陆续死亡。这是20世纪 世界上最大的由燃煤引发的城市烟雾事件。

What does our earth look like?
And what should we do?
Energy conservation
Use green shopping bags instead of plastics Turn off the light before you get out Raise the temperature of air-conditioning Ride a bicycle,or to take a bus instead of a car Turn down the brightness and voice of your computer
The globle warming Increasing global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, including an expanse of the subtropical desert regions. Other likely effects include increases in the intensity of extreme weather events, changes in agricultural yields, modifications of trade routes, glacier retreat, species extinctions and increases in the ranges of disease vectors.
Water conservation
Recycling of water Use a washbasin when you wash and brush Discharge sewage after treatment
The beautiful planet of ours is our home. To take care of the world is to take care of ourselves. Let’s work together to keep our world alive and well.
What does our earth look like? How is our living environment? becoming a severe problem,which mainly caused by transport action and factories production. The air pollution changes the conditions that we depend on, such as the greenhouse effect and the acid rain. It causes many diseases,too.
That’s all.Thank you!
