Lime Scale Water in Domestic Boilers as the Main Toxic Factor in the Human Body

Abstract

This research is based on the study of boiler water with a high content of waste inside boilers. After many years of use, a very toxic lime scale (LS) is formed in the boiler mixed with heavy elements, ions, and other molecules dangerous for human health. The high concentration of some heavy metals in domestic boilers is a problem in itself. During our study we created laboratory proof that inside domestic boilers contain extremely high concentrations of some heavy carcinogenic metals. Domestic boilers should have a simple system for cleaning the waste in the boiler that in our research contains heavy metals that can create profoundly serious problems in a person with normal metabolism. The chemical parameters analysed in the domestic boilers are: Cu (0.002-3.08) mg/L, Fe (0.001-0.97) mg/L, Cr+6 (0-0.31) mg/L, Al+3 (0.001-0.8<) mg/L, Ca+2 (56-200<) mg/dm3 , Cl− (12.3-45) mg/L, Cl2 (0-2.2) mg/L, PO4 −3 (0.04-1.3) mg/L, NO2-N (0.0006-2.9) mg/L, NH3-N (0.001-0.5) mg/L. The high presence of heavy metals in water has recently been causing serious problems. Scientific research in the field of environmental toxicology has given us more and more answers to the questions of where many human health problems can come.
