Overview
Marker-corpus ingest from the archived source file.
Evidence fitness
Human breast-milk contaminant source with measured element concentrations and fire-period exposure stratification. It can support breast-milk context for element detection/non-detection and smoke-event comparison. It should not be treated as infant-food product occurrence evidence.
Key numbers
- One hundred two women completed the infant-feeding survey.
- Seventy-seven women provided 92 breast milk samples; 29 samples were collected during the fire period and 48 outside the fire period for the cross-sectional comparison.
- Twenty elements were quantified. Calcium, potassium, magnesium, sodium, sulphur, and copper were detected in all samples.
- No samples collected during the fire period contained chromium, lead, nickel, barium, or aluminium.
- The source reports no statistically significant difference in element concentrations between samples collected during versus outside the fire period.
- Element LODs were 0.20-10.00 mg/kg milk for sodium, potassium, sulphur, iron, calcium, and magnesium, and 0.01-0.50 mg/kg milk for the remaining elements.
Methods
The paper quantified 20 elements using ICP-MS or ICP-OES. PAHs were quantified separately by tandem GC-MS/MS. Fire exposure was estimated using fixed-site air-quality monitoring data and smoke-day classification for the 2019/2020 Australian landscape fire period.
Implications
Use this source as source-scoped breast-milk contaminant evidence. Keep the matrix as breast milk and do not route it as formula, infant-food, or finished product evidence.
