Blood lead levels measured prospectively and risk of spontaneous abortion
Risk of spontaneous abortion and blood lead levels prospectively measured are discussed based on a nested case-control study carried out in a cohort of pregnant women in Mexico City with 668 women enrolled. The odds ratio for spontaneous abortion, or miscarriage, was 1.8 for every mg/dL increase in lead in the blood. Low-to-moderate lead exposures may increase the risk for spontaneous abortion at exposures comparable to US general population levels during the 1970s and to those for many populations of the world in the late 1990s. In some occupations exposures are much higher.

Childhood lead poisoning and vinyl miniblind exposure
Vinyl miniblinds may be a source of unhealthy lead exposure in children. Vinyl miniblinds may contain lead that can be detected in dust on the blind slats. Researchers in North Carolina tested 278 miniblind samples from homes and day care centers, and found that 91% contained enough lead in the dust to meet or exceed lead hazard standards. Miniblinds were the primary source of lead exposure in 9% of 92 children with lead poisoning. The widespread popularity of miniblinds suggests that blind exposure should be evaluated in lead poisoning risk assessment.
