i understand that we used to have scrap metal and rubbish iron and bits of copper lying all round the villages, particularly in the developing world.
હું સમજું છું કે આપણી પાસે હતી સ્ક્રેપ મેટલ અને કચરો આયર્ન અને તાંબાના બિટ્સ બોલ્યા આજુબાજુના ગામો, ખાસ કરીને વિકાસશીલ વિશ્વમાં.

the bronze age was followed by the iron age starting from about 1300 bc and reaching most of eurasia by about 500 bc, although bronze continued to be much more widely used than it is in modern times.

this is true but it should be clarified that the charcoal given in emergency medical treatment is “activated” charcoal and that it is only helpful against certain types of poisons. a dramatic example of this is the tale of professor touery, who in 1831 in front of his colleagues at the french academy of medicine ingested 15 grams of the deadly poison strychnine (that is ten times the lethal dose). he lived to tell the tale because he mixed the strychnine with activated charcoal.activated charcoal is charcoal that had been processed to make it even more porous than normal charcoal. this gives the charcoal even more surface area. a single gram of activated charcoal can have a surface area of 1000 m2**. (in terms most americans will understand better, 1 lb of activated charcoal has the same surface area as 84.8 football fields) it is this vast surface area that allows the charcoal to adsorb poisons and other substances. when a material adsorbs something, it attaches to it by chemical attraction. the vast surface area of activated charcoal gives it a countless number of bonding sites. this is why activated charcoal helps to prevent the poison from being absorbed into the body. but it won’t adsorb everything, activated charcoal isn’t effective in bonding to :*.lithium (eskalith, lithobid), strong acids and bases, metals and inorganic minerals such as sodium, iron, lead, arsenic, iodine, fluorine, and boric acid*.alcohol (such as ethanol, methanol, isopropyl alcohol, glycols, and acetone)*.hydrocarbons (such as petroleum distillates and plant hydrocarbons such as pine oil)as such, it will not prevent these poisons from being absorbed into the body. bummer... you can't erase a night of binge drinking by eating the wood dregs from the fireplace.it’s a good time to point out the difference between adsorption and absorption. adsorption is the adhesion of substances to a surface. absorption is when a fluid permeates a solid or is dissolved by a liquid. the poison adheres to the surface of the charcoal and since the charcoal cannot be absorbed by the digestive tract, it passes out of the body.
