PC Board contains toxins which are very harmful to humans and the environment.
TB is not directly caused by the burning of PC Board but caused by bacteria that spread from person to person. When someone who have tuberculosis coughs, speaks, sneezes, spits, laughs or sings then it spread from that person to others. The burning of PC Board or any e-waste containing plastic releases toxins which make one susceptible to various respiratory diseases. When the body becomes weak due to respiratory infections then there is a chance that the person may get Tuberculosis. Toxins have an effect on the person’s digestive system also. And contraction of TB in one’s body is also closely related to food and nutrition. So burning of PC Board does not directly causes TB but certainly prepares one’s body for contracting TB. Maybe this has happened in your friend’s case.
Now in order to help your friend please ensure that your friend should complete the full medication course. If he stops this medication then the TB might become worse and after that treatment of TB will be difficult.
Instead of burning PC Board he can do dismantling of keyboards, tearing of wires, sorting of e-waste, dismantling of other types of e-waste where he is not exposed to smoke and dust. He should also wear a mask while doing work. He should take up a job where he is not exposed to dust and smoke. His family and his friends should help him in coming out of this problem.
