      <title>HERBICIDES FOR HIGHWAY USE. FINAL REPORT - PHASE III</title>
      <link>https://trid.trb.org/View/285744</link>
      <description><![CDATA[Numerous single and combination chemical applications were evaluated in four major areas of emphasis in an effort to provide a year-round chemical spraying program.  The major areas were control of winter annual weeds, smutgrass control, control of lovegrass and suppression of fescue seedheads.  A determination of arsenic residues from MSMA sprayed roadsides was compared with unsprayed roadsides. Sulfometuron (Oust) or Atrazine (Aatrex, et al.) were determined the most effective treatments for control of winter annual broadleaf weeds.  Hexazinone (Velpar) or dalapon (Dowpon M) were demonstrated as effective treatments for control of smutgrass.  No satisfactory treatments were found for the selective control of lovegrass on roadside. Trials for suppression of fescue seedheads were conducted in three different years and on two dates of application in the first two years to determine and compare the efficacy of sethoxydim (Poast) and related compounds with sulfometuron (Oust) and glyphosate (Roundup).  Analyses of soil samples collected from roadsides sprayed and not sprayed with MSMA indicated little or no evidence of arsenic accumulation after nine years of the roadside spraying program.]]></description>

      <title>ENVIRONMENTAL AND HEALTH EFFECTS OF MSMA APPLICATION ALONG LOUISIANA HIGHWAYS. EXECUTIVE SUMMARY</title>
      <link>https://trid.trb.org/View/212703</link>
      <description><![CDATA[The use of MSMA as a grass control herbicide along Louisiana highway's rights-of-way is desirable because of its economic advantage in chemical mowing and Johnson grass control.  Since MSMA contains arsenic, there has been some public concern over MSMA's possible adverse environmental and health effects due to the buildup of arsenic residues in soil, water and biota.  The objective of this project was to obtain baseline arsenic residue data along the highway rights-of-way of five selected highways in Louisiana:  LA 7/and US 171/Calcasieu Parish. In summary, 432 or 77.3% of all surface-soil samples collected contained from 0 to 50ppm of arsenic-residues while 127 or 22.7% contained over 50ppm.  Most, 14 of 18, water samples contained arsenic residues below 50ppb which is the EPA Primary Drinking Water Standards.  The background (baseline) arsenic-residue concentrations in in surface soil samples ranged from 3.72ppm to 13.9ppm of arsenic. The environmental and health risks due to the accumulation of arsenic residues in soil and water appear to be minimal. It was recommended that DOTD continue this monitoring program to maintain a current assessment of the environmental and health risks of MSMA application. (Author)]]></description>

In summary, 432 or 77.3% of all surface-soil samples collected contained from 0 to 50 ppm of arsenic residues while 127 or 22.7% contained over 50 ppm.  Most, 14 of 18, water samples contained arsenic residues below 50 ppb which is the EPA Primary Drinking Water Standard.  The background (baseline) arsenic-residue concentrations in surface-soil samples ranged from 3.72 ppm to 13.9 ppm of arsenic.

      <title>UPTAKE AND EXCRETION OF MSMA IN WORKERS APPLYING THE HERBICIDE TO HIGHWAY RIGHTS OF WAY. FINAL REPORT</title>
      <link>https://trid.trb.org/View/274027</link>
      <description><![CDATA[This study followed uptake and excretion of total arsenic from MSMA in workers applying the herbicide during the spraying season.  Urine, blood and hair samples were collected from workers as well as air samples taken from the workers' breathing zone.  Arsenic concentrations in air samples ranged from 0.001 - 1.086 microgram/cu m with no significant difference in air arsenic concentrations over time.  Blood arsenic values ranged from 0.0 - 0.2 mg/l, well within the limits considered normal.  Arsenic urine values ranged from 0.002 - 1.725 mg/l.  This is above the normal value range but is consistent with arsenic levels in urine following a seafood meal.  Geometric mean arsenic concentration in urine increased during the week but returned to low levels on weekends.  There was no accumulation of arsenic in urine over time.  Hair arsenic concentrations ranged from 0.02 - 358.0 mg/kg.  Arsenic concentrations increased during the spraying season but returned to preseason levels once herbicide application ceased.  Three workers had pre-exposure values above the range considered normal for arsenic content of hair. However, only one of the three workers was consistently above normal values throughout the study period.]]></description>

      <title>DARK CORNERS OF CORROSION</title>
      <link>https://trid.trb.org/View/140281</link>
      <description><![CDATA[Corrosion problems are reviewed which are being researched by the National Bureau of Standards (which provides a central resource for groups of researchers in public and private laboratories around the world).  A workable method is being developed for chemically neutralizing or preventing the transformation of mercury into its poisonous forms. Such a method could be applied to the threat of poisioning from other heavy metals such as cadnium, lead, tin and arsenic.  Work was performed on finding substitute shielding materials for buried telephone cables.  Experimentation is underway to determine how steel pilings jetted 5.7 m into th sand will fare under various systems of protection against wind, wave, salt spray and microorganisms.  Corrosion in surgical implants and desalting plant components is being investigated, and stress corrosion cracking is receiving attention.  The tribo-ellipsometry technique is described which has been devised as an aid in predicting an alloy's performance against stress corrosion cracking.  The opinion is expressed that corrosion can be warded off by the use of improved materials, design and preventive maintenance.]]></description>

      <title>PAPER DRAINS DEWATER EMBANKMENT</title>
      <link>https://trid.trb.org/View/125561</link>
      <description><![CDATA[A JAPANESE-BUILT RIG WHICH PLACES PAPER DRAINS AT THE RATE OF 1.5 PER MINUTE IS DESCRIBED.  EIGHT THOUSAND VERTICAL DRAINS WILL DEWATER AND CONSOLIDATE A LAYER OF MIXED SILT, CLAY AND SAND BELOW AN EMBANKMENT FOR A 2-MILE ROADWAY SECTION IN QUEBEC.  FIFTY-FOOT-LONG CARDBOARD STRIPS WILL BE USED FOR HALF THE PROJECT.  THE 4 X 0.125-INCH PAPER STRIPS ARE IMPREGNATED WITH ARSENIC SALT TO SLOW BACTERIAL ACTION AND MELAMINE RESIN (TO INCREASE WET STRENGTH).  ONCE IN PLACE WATER IS FORCED UPWARD THROUGH 10 SMALL TUBULAR CHANNELS BETWEEN THE OUTSIDE GLUED FACES OF THE DRAINS BY THE WEIGHT OF THE EMBANKMENT.  A DRIVING MANDREL PULLS THE PAPER OFF 1,300-FT ROLLS AND CARRIES IT INTO THE GROUND. AT THE DESIRED DEPTH, THE MANDREL RELEASES THE STRIP AND WITHDRAWS.  THE AVERAGE RATE OF PROGRESS IS 150 PAPER DRAINS PER DAY.  THESE DRAINS PRODUCE FASTER CONSOLIDATION AT A LOWER COST THAN CONVENTIONAL SAND DRAINS.]]></description>

      <title>CONCRETE MIX WATER--HOW IMPURE CAN IT BE?</title>
      <link>https://trid.trb.org/View/102063</link>
      <description><![CDATA[THE EFFECTS OF CHEMICALS DISSOLVED IN MIX WATER ON THE STRENGTH DEVELOPMENT OF MORTAR AND CONCRETE ARE REVIEWED. NATURAL, FRESH WATER RARELY CONTAINS MORE THAN 2000 PPM. (0.2 PERCENT) OF DISSOLVED SOLIDS, AND IS GENERALLY SUITABLE AS MIX WATER. WATERS CONTAMINATED WITH INDUSTRIAL WASTES APPEAR ALSO TO BE GENERALLY SUITABLE AT THESE LOW CONCENTRATIONS. MUCH LARGER CONTENTS OF THE IMPURITIES GENERALLY PRESENT IN NATURAL WATERS CAN ALSO BE TOLERATED EXCEPT FOR THE ALKALI CARBONATES AND BICARBONATES WHICH MAY HAVE SIGNIFICANT EFFECTS EVEN AT 2000 PPM. IMPURITIES THAT MAY BE DETRIMENTAL AT MODERATE CONCENTRATIONS ARE THE SULFIDES, IODATES, PHOSPHATES, ARSENATES, BORATES, AND COMPOUNDS OF LEAD, ZINC, COPPER, TIN, AND MANGANESE. ORGANIC SOLUTES ARE ALSO SUSPECT, ESPECIALLY SUGARS. RISK OF CORROSION OF STEEL LIMITS THE USE OF SEA WATER. /PCA/]]></description>
