Read and interpret the following information using the following abstract from a scientific journal article. In 2-3 sentences, summarize what you understand from this research
![ABSTRACT: Lead (Pb) is a potent neurotoxicant with no safe level of exposure. Lees opm
Elevated levels of Pb and arsenic (As) are found in the air and soil near facilities
that recycle lead-acid batteries in the United States. In urban Los Angeles
County, California, a facility processed ~11 million batteries per year and
operated for decades without proper environmental review. Measuring Pb and As
in shed deciduous teeth is a promising technique to assess prenatal and early life
exposure. In this pilot study coined the "Truth Fairy" Project, 50 shed deciduous
teeth from 43 children living their entire lives within 2 miles of the smelter were
analyzed to understand retrospective exposure to toxic metals using a
community-driven research approach. Concentrations of Pb and As in teeth
were assessed using laser-ablation-inductively coupled plasma-mass spectrometry.
Soil Pb concentrations were determined using spatial kriging of surface soil
measurements. The mean prenatal calcium normalized Pb levels in teeth samples
(reported as a ratio 208 Pb:*Ca) was 4.104 x 104 (SD 4.123 x 10-4), and the
mean postnatal 20$Pb:**Ca level was 4.109 x 10-+ (SD 3.369 × 10-4). Adjusted for maternal education and batch, we observe
positive significant relationship between prenatal teeth Pb per 100 ppm increase in soil Pb (ß = 3.48, 95% CI 1.11, 5.86). The
Truth Fairy study suggests prenatal and early life exposure to toxic metals is associated with legacy soil contamination in an
urban community near a smelter.
