Field Portable XRF analysers currently on the market weigh less than 2 kg, and have limits of detection on the order of 2 parts per million of lead (Pb) in pure sand. Using a Scanning Electron Microscope and using EDX, studies have been broadened to organic based samples such as biological samples and polymers.
Lead-based paint inspections will evaluate all painted surfaces in a complex to determine where lead-based paint, if any, is present. The procedures for lead inspections is outlined in the United States Department of Housing and Urban Development (HUD) Guidelines, Chapter 7, 1997 Revision. The other testing is a lead-based paint risk assessment.

[2] After a house has been discovered to contain lead, its owner has four options they can pursue to prevent lead poisoning: they can encapsulate it, enclose it, remove it or replace the contaminated items.
Lead evaluations are done using a method called X-Ray fluorescence (XRF), which gives a result in 4–8 seconds with a 95% accuracy at the 2-sigma level. As of 2018, there are an estimated 37 million homes and apartments with lead paint in the United States. [39]
Lead as an alloying element in steel containing up to 0.35% lead by weight, aluminium containing up to 0.4% lead by weight, and copper alloy containing up to 4% lead by weight is permitted. [23] (Category 6c) Lead in high melting temperature type solders (i.e. lead-based solder alloys containing 85% or more lead by weight). (Category 7a)
