Once lead is mined, processed, and introduced into the human environment it is a potential problem forever. No current technology will destroy it or make it permanently harmless. However, exposures to lead can be controlled. The occupational hazards of lead were first reported in 1713 by Bernardo Ramazzini, who described lead intoxication in potters working with lead glazes. In 1913, Dr. Alice Hamilton, an American occupations health doctor, wrote about painters and the hazards of their work. Permanent Abatement and work over PEL - YES Abatement Planning - NO Hazard Evaluation - NO Clearance Inspections - NO - Certified Lead Worker Why was lead used in paint? - As a pigment, to add durability and corrosion control, and as a drying agent. Permanent Abatement and work over PEL - YES Abatement Planning - YES Hazard Evaluation - NO Clearance Inspections - NO - Certifications for Certified Lead Supervisor Sources of environmental lead contamination - The principal industrial use of lead is in the manufacture of electrical storage batteries. Other uses include the production of ammunition, various chemicals, and sinkers for fishing and etc. Lead exposure - The major exposure to lead for most adults comes from the work place (inhalation). Surface dust and soil contamination with lead are the major sources of lead exposure for infants and young children ingestion. Children: drinking water primarily from leaded solder, brass fittings and fixtures, and service lines can contribute to lead poisoning. Permanent Abatement and work over PEL - NO Abatement Planning - YES Hazard Evaluation - NO Clearance Inspections - YES - Certifications for Certified Lead Project Monitor Permanent Abatement and work over PEL - NO Abatement Planning - NO Hazard Evaluation - YES Clearance Inspections - YES - Certifications for Certified Lead Inspector and Assessor Lead Base Paint - The amount of lead-based paint in housing is significant - approximately 64 million (pre-1978) private U.S. residences contain at least some lead-based paint. Children ingest lead-based paint by normal hand-to-mouth activity. Young children absorb a significantly higher percentage of ingested lead than adults. Lead absorption is increased by malnutrition and poor diet. Lead has been used in paint for what three main reasons? - as pigment, to add durability and corrosion control, and as a drying agent Lead in surface dust and soil can come from? - Weathering and chipping of lead-based paint, scraping and sanding of lead-based paint in preparation for refinishing, renovations that break surfaces painted with lead-based paint, abrasion and/or impact on doors and windows, atmospheric fallout from the combustion of leaded gasoline that was deposited prior to the phase-down in use, factory emissions, dust and dirt that is carried into the home on shoes and clothing (especially from factories or construction sites or by pets) What is the greatest risk of lead exposure that people face? - Man-made processes and products Lead in water - Lead-contaminated drinking water also contributes to the overall level of exposure - from as little as 5 percent to more than 50 percent of a child's total lead exposure. (NAETI Exam: 20% contribution) Currently, what is the principal industrial use of lead? - Manufacture of electrical storage batteries Lead in food - Contamination from containers with lead solder, lead glaze, or other materials with lead, by airborne lead from industrial or automobile emissions deposited on to crops or water, by uptake into food crops from lead in soil or pesticides applications, and doing transportation or processing. A phase-out of lead solder in cans began in the late 1970s. Food containers: lead oxide is sometimes used to manufacture glazes for protecting ceramics and etc. Where does the major exposure to lead for most adults come from? - The work place Lead in other sources - Vinyl miniblinds are another potential source of lead in a residence. CDC, CPSC, and the public health have identified the following: crayons (imported from Chile), painted metal playground equipment, pool cue chalk, calcium supplements (made from bone or oyster shell), some hair dyes (lead acetate) What are the major sources of lead exposure for infants and young children? - Surface dust and soil contaminated with lead CPSC - Consumer Product Safety Commission True or False A person may become poisoned through exposure to a single high-level source of lead or through the cumulative effect of repeated exposures to low-level sources of lead. - True Health effects of lead exposure - The three systems where the effects are most dangerous are: the central and peripheral nervous system. the cardiovascular system (including the blood forming system), and the kidneys. Exposure to high concentrations of lead can cause: retardation, convulsions, coma, and death (sometimes)
