What is Lead?

​

Lead, a naturally occurring metallic element abundant in our planet's crust, has found extensive use across diverse products. From gasoline to paint, plumbing pipes to ceramics, and even cosmetics, lead has been a ubiquitous presence. Its incorporation into paint, for instance, served not only as a pigment to enhance color vibrancy but also as a means to prolong color retention. Additionally, lead's inclusion facilitated quicker drying times and imparted durability and moisture resistance, rendering lead-based paint particularly favored for residential applications. Despite its softness, high malleability, and corrosion resistance, exposure to air tarnishes its surface.

Understanding the Importance of Testing and Health Implications

​

Lead poses the greatest risk to infants and children, whose developing immune systems render them more vulnerable to its deleterious effects. Elevated lead levels in children can lead to a myriad of issues including learning disabilities, hearing impairment, behavioral disorders, and even fatalities. However, adults are not immune to its dangers, experiencing reproductive complications, pregnancy issues, and hypertension, among others. Consequently, the U.S. Government implemented a ban on lead paint in 1978. Nonetheless, homes constructed before this date remain a primary source of lead exposure and dust in the U.S.

​

The predominant routes of lead exposure include ingestion or inhalation of lead dust particles. Numerous laws, administered by the Environmental Protection Agency (EPA), regulate lead as a pollutant, including the Toxic Substances Control Act (TSCA) and EPA Renovation, Repair, and Painting (RRP) Guidelines.

The Testing Procedure

​

Lead testing involves the collection of paint chips, subsequently analyzed by accredited laboratories. Alternatively, X-Ray Fluorescence (XRF) lead analyzers offer on-site results. Moreover, lead wipes are utilized post-remediation to verify the successful removal of settled lead dust, ensuring comprehensive safety measures.
