The main treatment of heavy metal poisoning is termination of exposure to the metal. Treatment also consists of the use of various chelating agents that cause the toxic (poison) element to bind with the drug and be excreted in the urine.
Sometimes they will say, quÃ© pasa, que pasÃ³, or que te pasÃ³ to mean what's wrong or what happened. If you're trying to say what's up, I would recommend quÃ© ondas, quÃ© tal, que haces - this one meaning what are you doing. If you have any other Spanish questions feel free to ask.
Que is what in Spanish. Sera is the future tense so will be is correct (also in Spanish). What in French is Quoi, not Que. While Â«quoiÂ» does mean what, the use of Â«queÂ» in Â«que sera, seraÂ» would be correct, were it French. I do not believe Â«quoi sera, seraÂ» would make sense. AFAICS, were it not for the pronunciation, the line would be perfectly acceptable French.
