Data Download of Mercury Datasets

A database of ~35,000 fish tissue mercury records was compiled by USGS from various sources, including the following:

• National Pesticide Monitoring Program (NPMP)
• National Contaminant Biomonitoring Program (NCBP)
• Biomonitoring of Environmental Status and Trends (BEST) datasets of the USFWS and USGS.
  http://www.cerc.cr.usgs.gov/data/data.htm
• Environmental Monitoring and Analysis Program
  (EMAP):
  http://www.epa.gov/emap/
• Regional EMAP (REMAP) of USEPA
  http://www.epa.gov/emap/remap/index.html
• State agency data as compiled in USEPA’s National Listing of Fish and Wildlife Advisory (NLFWA) database
  http://map1.epa.gov/

Selected records were required to have: a non-zero mercury concentration, valid species identifier; be identified as sampled as whole fish, skin-on fillet skin-off fillet, carcass, edible, eggs, liver, viscera (samples identified as ‘fillet’ only were rejected); and have a length measurement that is appropriate for that species.

Please contact the EMMMA administrative team (emmma-admin@usgs.gov) with corrections and appropriate additions to this dataset.

Please Note: These data were updated during September, 2006.

Data for point source emissions of mercury (~24,000 sites) were extracted from the U.S. Environmental Protection Agency's National Emission Inventory (NEI) database (1999 NEI Point Source Facility Summary).

All NEI data and documentation are available at:

The Mercury Deposition Network (MDN) is a network of monitoring stations under the National Atmospheric Deposition Program (http://nadp.sws.uiuc.edu/mdn/).

The objective of the MDN is to develop a national database of weekly concentrations of total mercury in precipitation and the seasonal and annual flux of total mercury in wet deposition.

The data will be used to develop information on spatial and seasonal trends in mercury deposited to surface waters, forested watersheds, and other sensitive receptors.

This file contains a shapefile with names, coordinates, and links to data for the 81 sites currently active in the MDN.

Data for 1100 mercury mine locations were extracted from the USGS's Minerals Availability and Mineral Industry Location Database (MAS/MILS). This coverage and associated databases contain data from selected fields of five tables in the MAS/MILS database. A separate file containing all MAS/MILS mine locations (188,000 records) is also included.
