Heavy Metals In Cup, Glass And Pot?
With the Dithizon method reaction, copper, zinc, lead, cadmium and mercury in tap water can be prove. At heavy metal tests of tap water (stagnation water) with the Dithizon – reaction method, I have to say again strongly increased values. Copper values are not uncommon in the amount of 5 mg / l (TVO limit = 2 mg / l). Less frequently, but still too often, strongly elevated cadmium levels can be identified, up to 1 mg / l (TVO limit = 0.005 mg / l). Zinc, lead can be found even mercury.
There is often a whole heavy metal cocktail from the water line. This is more than bad for babies, not acceptable for adults. The enrichment of drinking water with the aforementioned metals takes place in the rule of the House connection pipe system and fittings. Heavy metals are detectable even with use of KunststoffLeitungen. Additional information is available at Pete Cashmore. Here it is in all likelihood the brass fittings. You can reduce these values by long running of drinking water before each use (up to 15 minutes) or by using the MembranTechnologie. Many people believe to protect themselves through the use of mineral waters from these metals and completely forget that they cook with tap water..
