@@SunriseLAW I will give them credit that after nuclear war they will be the ones restoring some modern conveniences to the world at the cost of more human lives. Its amazing in one way and truly tragic in another the world these people are forced to live in.
As a kid i didn't know what lead poisoning was, i had an air gun and chewed the mushy lead pellets for fun. Don't know how much lead i did intake during the process but now am 38 and healthy ❤️❤️❤️👍👍. It happens in Pakistan bros! You Westerner are taking everything so seriously. 😂😂😂😂
Lead exposure can cause high blood pressure and brain, kidney and reproductive health issues in adults. Symptoms of lead poisoning include headaches, stomach cramps, constipation, muscle/joint pain, trouble sleeping, fatigue, irritability, and loss of sex drive. Most adults with lead poisoning don't look or feel sick. They just die.
According to NIH... It is usually assumed that lead can be absorbed through the skin only if it is present as an organolead compound such as tetraethyllead or lead naphthanate. It has been found, however, that finely-powdered lead metal or lead nitrate solution placed on the skin results in rapid absorption of lead, and transport of the metal around the body. The absorbed lead appears in sweat and saliva, but not in blood or urine. The application of 6 mg of lead as 0.5 M lead nitrate to the left arm resulted in an increase in lead concentration in pilocarpine-induced iontophoresis sweat samples taken from the right arm, from an initial value of 15-25 micrograms Pbl-1 to greater than 300 micrograms Pbl-1 after 2 days. Saliva lead increased from 2.5 to 15 micrograms Pbl-1 in the same period. The rate of lead absorption through the skin increases with increased sweating of the skin. Since no measurable increase in blood lead has been found, the lead must be transported in the plasma and rapidly concentrated into the extracellular fluid pool (sweat and saliva), without significant uptake by the erythrocytes, and with a very low transient concentration in the plasma. Workers occupationally exposed to lead have extremely high levels of lead in sweat even though their lead in blood is only moderately elevated. Lead absorbed through the skin may be eliminated via sweat and other extracellular fluids, and hence as ingested lead, but this will need to be proved by further studies.

Well, at least they're wearing safety sandals and flip flops. It's amazing what can be accomplished with no safety standards, quality control or regard for human life.
For all those lead poisoning guys....As a kid i didn't know what lead poisoning was, i had an air gun and chewed the mushy lead pellets for fun. Don't know how much lead i did intake during the process but now am 38 and healthy ❤️❤️❤️👍👍. It happens in Pakistan bros! You Westerners are taking everything so seriously. 😂😂😂😂
Creo que lo negro que queman son placas positivas destruidas , las queman para volverla a su estado inicial y agregarse la a las placas con rejilla de plomo.
Und solange sich darum keine Sau schert, braucht keiner in Deutschland auf die Idee kommen mich zu gängeln ich darf nichtmehr mit meiner Familie in den Urlaub fliegen
Geil ist ja, dass das 300 Millionen Leute in Pakistan und1,5 milliarden Leute in Indien sind. Die geben alle einen Scheiß auf Umwelt und Klima. Aber ich darf hier keine Trinkhalme mehr kaufen.
Yes, they do. It's the gunk from the bottom of lead-acid battery casings when they recycle/rebuild them. It's a horror show of slow, chronic, lead poisoning.
That's lead (II) dioxide which they appear to be recovering from scrap batteries etc. It's not a substitute as such, the paste needs to be smeared into the lead grid of the positive terminal and dried.
you use paste because it's permeable by the electrolyte and it's got more surface area. more surface area = more stuff touches other stuff = more chemical reaction = more zap juice
Usually the negative plate consists of lead, and the positive plate is lead dioxide paste smeared into the lead substrate grid (the brown / light brown stuff that starts off a bit yellow).
@HK-fz5rn sometimes batteries also have some antimony added to the lead grid to give it more structural strength as batteries dislike the constant vehicle vibration, which leads to grid failure then cell failure.
They are obiviously REDUCING the lead dioxide PbO² from dead positive plates to PbO with kerosen but why? Is n't PbO² the required material for positive plate??
A discharged positive (& negative for that matter)plate is PbSO4, they're burning it to hopefully get PbO2 back. The reaction is supposed to give PbO + SO3, at 1000°C but slowly burning it could yield PbO2 + SO2 I guess? SO2 & SO3 are both precursors to H2SO4, I'd want to capture those fumes if I needed H2SO4 ? SO2 is supposed to be mildly toxic, often used in food preservatives, SO3 is highly corrosive & toxic, mixed with water it makes H2SO4. SO those fume will cause acid rain. Inhaling SO3 is basically poisoning yourself & 10 villages around you.
A discharged battery plate (both +ve & -ve) is PbSO4. Burning it gets you SO2, or SO3 at high enough temperatures. SO2 isn't too bad unless you breath in it. SO3 is highly corrosive & toxic, causes acid rain. It's mist is odorless. It's a hazard.
@@harshivpatel6238 Yep, that is a good reasonning, SO² goes up, one O goes with the fuel (it burns candlewax fiercely, i did it in my lab) and remains PbO² or PbO depending on the oxygene left. Thanks for your "positive" reply! 😀
Hell lots of incomplete details and lack of proper process. What we are suppose to see? How they are working or try gain some good knowledge from video?
Hay que deducir el polvo negro que queman son placas positivas destruidas, las queman y regeneran el elemento (peróxido de plomo) lo trituran lo vuelven masa , y se lo incorporan a las placas negativas. LISTO.
