Exposure Data

Exposure data can tell you about the levels of measured chemicals or other agents in people (such as blood lead levels).

Each link is described. We identify the type and/or source of data, timeframe, geographic coverage and presentation (tables, maps or reports). Some additional comments are also provided.

These data cannot tell you how a person was exposed to the chemical. The measurement of a chemical in a person's blood or urine also does not by itself mean that the chemical causes disease. Advances in analytical methods allow us to measure lower and lower levels of environmental chemicals in people. Separate studies of varying exposure levels and health effects are required to determine which blood and urine levels are safe and which result in disease.

Lead

Lead Exposure
Heavy metals registry - contains information on the reporting of elevated levels of heavy metals, including lead, in adults in NY State with a link to the registry's most recent report. Elevated blood lead levels are shown by county, industry, and occupation.
Lead exposure in children
Report of lead exposure status of children in NY State, excluding NY City, including blood lead screening results, 2000-2001 – also a 2002-2003 update.
Eliminating Childhood Lead Poisoning in New York State: 2004-2005 Surveillance Report - Full Report
New York City Childhood Lead Poisoning Prevention Program
Annual report, including blood lead screening results. Number and rates of children tested and children with elevated blood lead levels (6 months to <6 years of age) – Table A4

Data source: NY City Childhood Lead Poisoning Prevention Program
Dates: Annual
Geographical area: Borough and United Hospital Foundation neighborhood

Environmental Chemicals

The National Report on Human Exposure to Environmental Chemicals (Third Report)
Provides an assessment of the exposure of the U.S. population to environmental chemicals through measurement of chemicals or their metabolites in blood and urine samples from a random sample of participants from the National Health and Nutrition Examination Survey (NHANES). This third report presents exposure data for 148 environmental chemicals. It is expected that additional reports will be released every two years.

Data source: National Health and Nutrition Examination Survey (NHANES)
Dates: 1999 -2002
Geographical area: United States
Comments: Tables present the geometric mean and selected percentiles of blood or urine concentrations of each chemical. Data are provided for age, gender, and some race/ethnicity groups. Levels from this report can be used as reference ranges by physicians and scientists to determine whether a person or group has a high exposure. People are selected for NHANES from the civilian, non-institutionalized U.S. population. The data cannot be abstracted to determine levels representative of a particular state. For each chemical some general information is also provided, such as sources of human exposure and known health effects.
