... Trace elements can reduce the fracture resistance of Zr-2.5Nb pressure tubes. The effects of hydrogen as hydrides and oxygen as an alloy-strengthening agent are well known, but the contributions of carbon, phosphorus, chlorine, and segregated oxygen have only recently been recognized. Carbides...

... A current EPA regulation prohibits the sale for burning in nonindustrial boilers of used oils and oil fuels contaminated above specified levels with total chlorine. Analytical techniques for determining total chlorine were evaluated to provide regulatory agencies and the regulated community...

.... In response to the November 1985 rule prohibiting the burning of used oils containing greater than 1000 ppm total halogens in non-industrial burners, the Clor-D-Tect 1000™ kit was developed. This field portable test kit is based on the detection of the total amount of chlorine in an oil sample. A complete...

... and silver by H 2 S (hydrogen sulfide) in the presence of additives such as NO 2 (nitrogen dioxide) or Cl 2 (chlorine molecule). It is shown that chemical reactions between gases are responsible for the acceleration of the rate of sulfidation of metals. Comparison with onsite measurements shows...

... systems receiving continuous toxic input, we found adverse effects of chlorine on species dispersal at 2 µg/L; however, net production was elevated at concentrations up to 100 µg/L. In tests with the herbicide atrazine, the number of species and the net production were stimulated at low levels (3 to 30 µg...

... content, organic content, and metal content. A statistical analysis plan (not a sampling plan) is proposed for handling heterogeneous chemical waste. incineration wastes combustion characterization petrochemical ash elemental composition metals organic compounds gas chromatography chlorine...

... The effect of chlorine exposures on the survival of freshwater aquatic life is of major concern within many of the waterbodies in the United States. Continuous chlorine exposures are a typical result of effluent releases from wastewater treatment plants. Intermittent chlorine exposures...

... A short-term, intensive study has been conducted on the potential impact of the chlorine, and to a lesser extent the ammonia and nitrite, associated with the domestic wastewater discharge from the city of Pueblo, Colo. on the water quality (beneficial uses) of the Arkansas River downstream from...

... This paper describes a rapid and reliable technique for the determination of chlorine and other oxidants in power plant and industrial cooling waters, with particular emphasis on seawater systems. The analytical work is based upon the standard technique of chlorine and oxidant reduction...

... for fish life, (2) identification of the relationships between fish populations and ammonia and chlorine in sewage discharges, and (3) development of a continuous stress function to evaluate the responses of aquatic communities to environmental and pollutional factors. The projects have resulted in useful...

... the petroleum industry's arbitrary reference mixture, two synthetic chlorinated effluents, and an effluent from a U.S. Army ammunition plant has demonstrated the potential of the present system for monitoring industrial wastewaters. aquatic toxicology biological monitoring bioassay ventilation...

... The toxicity of chlorine to one estuarine copepod, Acartia tonsa , appeared to be a simple dose response, that is, doubling the times of exposure had the same effect on mortalities as doubling the concentration of the toxicant. Chlorine toxicity to at least one of the other species tested...

... in the basket is replenished every 7 min by raising and lowering the water level in the tank by means of an automatic tidal siphon. Improvements in the test system are under development. acute toxicity flow-through mollusks larvae chlorine bromine chloride oyster coot clam invertebrates bioassays...

... A mechanism is proposed to explain differences in acute toxicity to different species caused by substances that form stable ammonia complexes. These substances include chlorine and various heavy metals. A deficiency in osmoregulation, resulting in damage to the gill but not the skin epithelia...

... and stress. The authors propose that chlorine diffuses down through a stress, and probably an oxygen concentration gradient reacts with the metal to destroy atomic bonds and produce stress corrosion. Specific reactions, however, have not yet been determined. X-ray diffraction studies of corrosion products...
