University of California Berkeley’s Health Research for Action is calling on OSHA to revise its occupational health standard on lead, which is now 30 years old.  In a report entitled “Indecent Exposure: Lead Puts Workers and Families at Risk,” the authors describe the adverse health effects of lead in workers with blood-lead levels of 5-10 ug/dL—a fraction of OSHA’s medical removal trigger of 60 ug/dL.  They note:

“…extensive research has shown that lead causes significant health problems in adults at much lower levels.  Cumulative exposure to low to moderate levels of lead has been associated with an increased risk of hypertension and reduced cognitive and kidney function.  …[and] exposure during pregnancy has been associated with an increased risk of miscarriage and impaired fetal growth…”

The Health Research for Action’s authors draw on work published over the last decade, in particular, articles published in NIEHS’s journal Environmental Health Perspectives, including:

As well as the Association of Occupational and Environmental Clinics (AOEC)’s medical management guidelines for lead-exposed adults (revised April 2007).

Health Research for Action provides just a sample of the compelling evidence that workers’ health continues to be harmed by workplace exposure to lead.  They note that among the 37 states with blood-lead reporting systems:

“1,649 adults in 2003 and 1,425 in 2004 had blood lead levels of 40 ug/dL or higher”

and in California alone,

“2,390 adults in 2004 had blood-lead levels between 10 to 39 ug/dL.”

 As I noted last year in Lead-Poisoned Workers in Alaska: Miners Beware!, some of the lead poisoning cases can be linked to a particular workplace, but we don’t necessarily have adequate regulations to PREVENT the exposure.  (MSHA, for example, doesn’t have a standard to protect mine workers from lead poisoning.)  When we see data showing that workers already are lead poisoned, this is the ultimate sign of failure.  Our nation’s lead-poisoning prevention measures are inadequate.

Health Research for Action’s report “Indecent Exposure: Lead Puts Workers and Families at Risk,” offers the following “Prescription for Change”:

  1. Eliminate all unnecessary uses of lead
  2. Revise OSHA standards
  3. Reward compliance
  4. Expand employer education and consultation
  5. Expand worker education and outreach
  6. Set enforceable reporting standards for clinical laboratories that perform blood lead tests
