Scientists warn that kangs waste fuel , pollute the atmosphere and endanger the health of farm families by releasing carbon monoxide and other dangerous gases indoors 科学家们提醒说，炕浪费燃料、污染大气并因为往室内释放一氧化碳和其它有害气体而危及农民们的健康。
Batteries contain heavy metals such as lead , cadmium and mercury that can be harmful if they leak into water supplies or eventually produce noxious gases which enter the atmosphere 含有的铅、镉、汞等重金属的电池一旦泄漏进入水源或产生有害气体进入大气，将对环境产生危害。
Third , we designed a waste gas disposing equipment , through which the danger gases such as sih4 can be get rid of by the nitrogen diluting and the rinsing of alkali solution 设计并制作了尾气处理装置，使设备排出的尾气能够经氮气稀释和碱水清洗而除掉其中的sih _ 4等易燃有害气体。
Third , research and analysis test of exhaust harmful air of the car and warning if it exceed the limit . how applied the speech integrated circuit comes realizing to proceeds to study 3 、对汽车排放有害气体的检测与超量报警控制进行了研究,并对如何应用语音集成电路来实现进行了探讨。
Generation of electricity that could otherwise be conserved introduces more harmful greenhouse gases and other noxious chemicals into the atmosphere from the powerplants that consume fossil fuels 比其二氧化碳和其它有害气体的排放，发电厂燃烧煤来发电产生的污染对环境的破坏要更大。
Article 42 in the transportation , loading and unloading , and storage of substances that may diffuse toxic or harmful gases or dust , sealing or other protective measures must be taken 第四十二条运输、装卸、贮存能够散发有毒有害气体或者粉尘物质的，必须采取密闭措施或者其他防护措施。
Article 35 in the transportation , loading and unloading , and storage of substances that may diffuse toxic or harmful gases or dust , sealing or other protective measures must be taken 第三十五条运输、装卸、贮存能够散发有毒有害气体或者粉尘的物质，必须采取密闭措施或者其他防护措施。
Article 29 . in the transportation , loading and unloading , and storage of substances that may diffuse toxic or harmful gases or dust , sealing or other protective measures must be taken 第二十九条运输、装卸、贮存能够散发有毒有害气体或者粉尘的物质，必须采取密闭措施或者其他防护措施。
Then to blow in nitrogen or other gas and to blow out exhaust harmful gas inside of the pipe in the gas way to lengthen service life and precision of thermocouple . operating temperature : 8001150 气路中氮气或其它惰性气体吹进去将管内有害气体送出来，延长热电偶使用寿命和精度。使用温度： 8001150 。
Large - scale machines employed in the construction to load and transport rocks also increase poisonous gases produced per hour . so the ventilation of the tunnel itself becomes a new problem 为实现快速施工，该隧道采用大型机械装碴、运输，这些机械单位时间内产生有毒、有害气体增多，通风较为困难。
