水银是仪器与实验中常用的物质,物理教师和实验室人员要经常接触水银。水银的蒸气极毒,一般说水银蒸气在空气中的含量达到1×10~(-5)毫克/升时,人在其中要发生中毒现象。例如盛水银容器破裂或做实验时不慎洒出相当分量的水银,流到地板、墙壁等隙缝中的水银的不断蒸发,都可使室内空气中水银蒸气含量达到上述数值。水银能贮积在人的肝
Mercury is a commonly used substance in instrumentation and experimentation. Physical teachers and laboratory personnel should always be exposed to mercury. Mercury vapor extremely toxic, generally said mercury vapor content in the air reaches 1 × 10 ~ (-5) mg / L, in which people want to happen poisoning. For example, when a container of mercury is broken or an experiment is performed, splashes of considerable amount of mercury are accidentally caused, and the continuous evaporation of mercury flowing into the gaps of floors, walls and the like can cause the mercury vapor content in the room air to reach the above value. Mercury can be stored in human liver
