Used with permission. Cadmium sulfide is the inorganic compound with the formula CdS. Welding and soldering of surfaces treated with cadmium sulfide release highly toxic cadmium oxide which may cause acute lung injury (see ICSC 0117 - cadmium monoxide). Cadmium (Cd) is a non-essential element for human nutrition and is an agricultural soil contaminant. The table shows element percentages for CdS (cadmium sulphide).
