Gas-liquid chromatographic determination of 3-trifluoromethyl-4-nitrophenol residues in fish Gas-liquid chromatographic determination of 3-trifluoromethyl-4-nitrophenol residues in fish

A procedure for the determination of 3-trifluormethyl-4-nitrophenol (TFM) in fish tissues is described. Homogenized tissues are extracted with hexane-ethyl ether; the extract is cleaned up by partitioning the TFM from the extracting solvent into 0.1N NaOH, acidifying the aqueous solution, and partitioning again with hexaneethyl ether. The TFM is methylated with diazomethane and analyzed...

Water resources of the Snake River watershed, east-central Minnesota Water resources of the Snake River watershed, east-central Minnesota

Glacial drift overlies sedimentary, igneous, and metamorphic rocks in the Snake River watershed. The Snake River, which drains an area of about 1,030 square miles, originates in an extensive area of peat bogs in the northern part of the watershed. It flows southward across gently rolling glacial terrain in which the major relief is near the river. Near the southern boundary of the...

Water resources of the Lower Minnesota River Watershed, south-central Minnesota Water resources of the Lower Minnesota River Watershed, south-central Minnesota

The lower Minnesota River watershed, an area of 2,005 square miles, is fairly flat west of the Minnesota River, but rises to a hilly ridge along the east side of the watershed. Most of the area is covered by ground moraine cut deeply by the Minnesota River and less deeply by its tributaries. Surface drainage is toward the Minnesota River at the northeast corner of the watershed. The...

Bedrock geologic map of the Greenwood quadrangle, Marquette County, Michigan Bedrock geologic map of the Greenwood quadrangle, Marquette County, Michigan

The Marquette Iron Range is presently ( 1973) the second largest iron mining district in the United States. Commercial iron deposits, now mostly concentrating-grade ore, are in the Negaunee Iron-formation, which is part of a thick sequence of metasedimentary rocks of Precambrian X age. These rocks are preserved in the west-trending Marquette synclinorium, and are flanked to the north and...

Water resources data for Michigan, water year 1973; Part 1, Surface water records Water resources data for Michigan, water year 1973; Part 1, Surface water records

Surface-water records for the 1973 water year for gaging stations, partial-record stations, and miscellaneous sites within the State of Michigan are given in this report. For convenience there are also included records for a few pertinent gaging stations in bordering States. The records were collected and computed by the Water Resources Division of the U.S. Geological Survey, under the...
