Chapter 6.1 Arsenic - World Health Organization

Arsenic concentrations in uncontaminated soil are generally in the range 0.2–40 mg/kg(2). However, levels of 100–2500 mg/kg have been found in the vicinity of copper smelters (2,3). In the past, numerous arsenical pesticides were used widely and, as a result, arsenic concentrations of 200–2500 mg/kg occurred in the soil of orchards (4).

Pickling and Passivating Stainless Steel

A matt grey is left on annealed mill products following descaling and pickling. Mechanical scale loosening roughens the surface. The terms'descaling', 'pic kling' and 'passivation' are often confused, but are distinct processes. It is important to be clear about the differences between these surface treatment processes as applied to stainless ...
