units & methodology

every concentration is normalized to ppb (parts per billion), which is identical to µg/kg. 1 ppm = 1,000 ppb = 1 mg/kg. 10,000,000 ppb = 1% by mass. methodology and limits of detection vary per source. always click through to the original record before quoting a number.

limitations to keep in mind

1. categorization is keyword-based. some borderline products may sit in the wrong bucket.
2. there is no cross-source dedup. the same product may show up in NYC NPSD and king county and pure earth as three separate rows.
3. about 11% of rows are recall records (CPSC, FDA) that don't carry a ppb value. those show as "recall record" in the data column.
4. some values are extreme, up to 1,000,000,000 ppb (= 100% by mass). these are real measurements of solid-state lead in religious amulets, kohl powder, or jewelry charms. not edible.
