Shocking Study Shows Glyphosate Herbicides Contain Toxic

Arsenical copper contains up to 0.5% arsenic which, at elevated temperatures, imparts higher tensile strength and a reduced tendency to scaling. It is typically specified in boiler work, especially locomotive fireboxes. It also helps prevent embrittlement of oxygen free copper by bismuth, antimony and lead by the formation of complex oxides. Copper with a larger percentage of arsenic is called
