Lead is a Block P, Period 6 element, while oxygen is a Block P, Period 2 element. Lead is a soft and malleable metal. The morphology of lead oxide nanoparticles is red or yellow crystalline solids. Lead oxide nanoparticles are graded as toxic and dangerous for the environment. The chemical properties of lead oxide nanoparticles are outlined in the following table. The physical properties of lead oxide nanoparticles are given in the following table. The thermal properties of lead oxide nanoparticles are provided in the table below.
Construction hazardous substances: Lead Lead can be found in construction workplaces. It is commonly used as a specialist material (eg roof flashings) and present in older buildings (eg in paint or pipework). Lead can cause serious health problems such as anaemia or kidney disease and published research has linked exposure to a small number of occupational cancers. This page tells you how to control these risks and why.
