Abstract

Background: Mercury is a toxic metal that has been used for centuries as a constituent of medicines and other items. Objective: We assessed exposure to inorganic mercury in the adult population of New York City (NYC). Methods: We measured mercury concentrations in spot urine specimens from a representative sample of 1,840 adult New Yorkers in the 2004 NYC Health and Nutrition Examination Survey. Cases with urine concentrations ≥ 20 μg/L were followed up with a telephone or in-person interview that asked about potential sources of exposure, including ritualistic/cultural practices, skin care products, mercury spills, herbal medicine products, and fish. Results: Geometric mean urine mercury concentration in NYC was higher for Caribbean-born blacks [1.39 μg/L; 95% confidence interval (CI), 1.14–1.70] and Dominicans (1.04 μg/L; 95% CI, 0.82–1.33) than for non-Hispanic whites (0.67 μg/L; 95% CI, 0.60–0.75) or other racial/ethnic groups. It was also higher among those who reported at least 20 fish meals in the past 30 days (1.02 μg/L; 95% CI, 0.83–1.25) than among those who reported no fish meals (0.50 μg/L; 95% CI, 0.41–0.61). We observed the highest 95th percentile of exposure (21.18 μg/L; 95% CI, 7.25–51.29) among Dominican women. Mercury-containing skin-lightening creams were a source of exposure among those most highly exposed, and we subsequently identified 12 imported products containing illegal levels of mercury in NYC stores. Conclusion: Population-based biomonitoring identified a previously unrecognized source of exposure to inorganic mercury among NYC residents. In response, the NYC Health Department embargoed products and notified store owners and the public that skin-lightening creams and other skin care products that contain mercury are dangerous and illegal. Although exposure to inorganic mercury is not a widespread problem in NYC, users of these products may be at risk of health effects from exposure.

  • The threat of mercury poisoning is real in the Caribbean.

    “The Caribbean population was previously believed to be under threat of mercury poisoning due to its higher than average fish consumption, however recent research including work by Drescher et al,5 Mckelvey et al.14 and this current study indicates that the threat of Mercury poisoning is indeed real in the Caribbean, but may be more due to its cultural use of skin lightening creams than fish cons”

    The Discussion (page not provided) reports inorganic mercury exposure from skin-lightening creams among Dominicans and possibly Caribbean groups in New York City. It does not establish mercury poisoning in the Caribbean itself, or show that creams pose a greater threat there than fish consumption. (LLM, conf=0.88)

  • Use of products like Deluxe Silken can lead to symptoms of mercury poisoning including Nephrotic Syndrome.

    “Deluxe Silken is approximately 14,000 times the recommended limit for Mercury and use of products of this kind can lead to symptoms of Mercury poisoning including Nephrotic Syndrome as have been documented in the US,14,29 Barbados5 and Indonesia.30”

    From The Evaluation of Total Mercury and Arsenic in Skin Bleaching Creams Commonly used in Trinidad and Tobago and their Potential Risk to the People of the Caribbean (2017) · cites this paper as [14]

    The paper’s Discussion reports US poisonings associated with mercury-containing skin-lightening creams, and its introductory toxicity passage says topical mercury can damage the kidneys (page not supplied). It does not identify Deluxe Silken or mention nephrotic syndrome, so it supports the general risk but not that specific condition or product. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Recent publications have reported that mercury is still being used in many skin lightening products found in Mexico, Africa, The United States and Asia.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
