1 year, after working 20-30 years, ten hundreds of chalks is worn down.Inevitably some chalk dusts are sucked from nostril.Suction
Whether chalk dust causes a disease, and is the problem of numerous teachers are most deeply concerned.
Chalk is made of gypsum.The composition of gypsum is calcium sulfate.Gypsum stable performance, it is nontoxic.For thousands of years, the traditional Chinese medical science
With gypsum (the calcium sulfate CaSO--42H2O containing the crystallization water) decoction, external application calcined gypsum (plaster of paris) applies affected part.Think energy
It is refrigerant antipyretic, promote the production of body fluid to quench thirst, myogenic sore.It is that gypsum powder is coated on blackboard with chalk-writing writing on the blackboard.During blackboard wiping,
Gypsum dust (chalk dust) in atmosphere it is of short duration wave after object plane and the ground fallen near blackboard.Its particle is larger, exists more
It is more than 100 microns, heavier, fall comparatively fast, the time of floating in the air is short.
The particle of chalk dust is larger, will not be drawn into lower respiratory tract mostly, again nontoxic to human body in itself plus gypsum, doctor
Educational circles also there is no because suction chalk dust causes the report of PUD D so far.Labour health department of China, in having for professional pneumoconiosis
Close in regulation, also the cause of disease not using chalk dust as lung.Although chalk dust has no big evil to human body, but China is millions of
Teacher, writing on the blackboard will be made with chalk daily, all lived in daily in the chalk dust after blackboard wiping, can still cause nose, pharynx,
Throat is uncomfortable.For quite a long time at present and from now on, teacher can write with chalk word, unlikely be attended class with mouth mask.
Therefore, constantly updating teaching facilities improves teaching job environment, and it is still necessary to ensure teachers ' health.
