Lead poisoning is a serious and sometimes fatal condition. It occurs when lead builds up in the body. Lead is a highly toxic metal and a very strong poison. It is found in lead-based paints, including paint on the walls of old houses and toys.
Galena [PbS] or lead sulphide is the main source of lead [Pb]. It is widespread in the district and is found along with the common vein minerals such as quartz, calcite, barytes and dolomite. Galena has been the most important commercial mineral found in the locality. It was the basis of the Lead Mining industry which was of economic significance, especially during the 18th and 19th Centuries. The Galena crystal group on the left, is an example which was found at Leadhills in the Glengonnar Mine.
