Associations between urinary 4-nitrophenol and indoor residential air and surface-wipe concentrations of methyl parathion have been studied in 142 residents of 64 contaminated homes in Uorain, Ohio (Esteban et al. 1996). The homes were contaminated through illegal spraying. A mathematic model was developed to evaluate the association between residential contamination and urinary 4-nitrophenol. There were significant positive correlations between air concentration and urinary 4-nitrophenol, and between maximum surface-wipe concentrations and urinary 4-nitrophenol. The final model includes the following variables number of days between spraying and sample collection, air and maximum surface wipe concentration, and age, and could be used to predict urinary 4-nitrophenol. 

An analysis of the EPA STORET Data Base (1980-1982) found that trichloroethylene had been positively detected in 28% of 9,295 surface water reporting stations nationwide (Staples et al. 1985). An analysis of 1,350 samples taken from 1978 to 1979 and 4,972 samples from 1980 to 1981 from the Ohio River system found a similar percentage of positive detections most positive samples had trichloroethylene levels of...

Interim results of an investigation of 185 subjects and later results from the complete follow-up sample of 305 subjects in a prospective study of inner-city children (>80% black) bom in Cincinnati, Ohio, were reported by Dietrich et al. (1986, 1987a, 1987b). Maternal PbB levels were measured at the first prenatal visit cord PbB was measured at delivery infant PbB levels were measured at 10 days and at 3 months of age and neurobehavioral tests were performed at 3 and 6 months of age. Mean PbB levels were as follows prenatal (maternal)—8.0 pg/dL (range, 1-27 pg/dL) umbilical cord—6.3 pg/dL (range,... 

Acrolein has been detected in effluent water streams from industrial and municipal sources. Municipal effluents from Dayton, Ohio, for example, contained between 20 and 200 pg acrolein/L in 6 of 11 analyzed samples (USEPA 1980 Beauchamp et al. 1985). Acrolein is also a component of many foods, and processing may increase the acrolein content (USEPA 1980). Acrolein has been identified in raw turkey, potatoes, onions, coffee grounds, raw cocoa beans, alcoholic beverages, hops (USEPA 1980), white bread, sugarcane molasses, souring salted pork, and cooked bluefin tuna (Thunnus thynnus) (Beauchamp et al. 1985). 

Hexachloroethane has occasionally been reported in drinking water in the United States. Hexachloroethane was detected in drinking water from Cincinnati, Ohio and three water supplies in the New Orleans area at concentrations ranging from 0.03 to 4.3 pg/L (Keith et al. 1976) in the municipal water supply in Evansville, Indiana (Kleopfer and Fairless 1972) and in 4 of 16 samples of Philadelphia drinking water (Suffet et al. 1980). It was also reported in 19 of 31 samples from private wells within 1 mile of a toxic waste dump in Hardeman County, Tennessee, at a median concentration of 0.26 pg/L (Clark et al. 1982). 

Chemical manganese dioxide (CMD). This form of Mn02 is used for batteries it is available from I. C. Sample office (Cleveland, Ohio, 44101). Shioiri et al. report it is superior to commercial activated Mn02 (Aldrich) and more convenient than freshly prepared activated Mn02 for dehydrogenation of 2-(l-ami-noalkyl)thiazolidine-4-carboxylic acids to the corresponding thiazoles (thiazole amino acids).

The U.S. Department of the Interior is conducting research under the U.S. Geological Survey to determine the impacts of highway de-icing chemicals on the groundwater quality of shallow, unconsolidated aquifers in Ohio, and to determine the salt concentration present in the soil and unsaturated zones. This research will include some analyses for dissolved cyanide in monthly samples from eight sites across Ohio. 

Protein Analysis. Protein concentrations were determined with a Spectronic 20 spectophotometer employing BSA as a standard (12). Each 0.1 ml sample was spotted on 3 cm2 Whatman No. 42 filter paper and air dried. Samples were stained with Xylene Brilliant Cyanin G (K and K Laboratories, Cleveland, Ohio), and the absorbance at 610 nm was recorded against a blank containing distilled water. Samples were corrected using controls containing all components except protein. 

The PDP represents partnerships between the USDA and the states in 2001, ten states (California, Colorado, Florida, Maryland, Michigan, New York, Ohio, Texas, Washington, and Wisconsin) participated in collecting and analyzing PDP samples. 

Current reviews of surface water monitoring data in the peer reviewed literature are lacking. The highest concentrations observed in surface waters of the United States sampled before 1984 were 394 and 120 ppb. These concentrations were observed in rivers in highly industrialized cities (Ewing et al. 1977 Pellizzari et al. 1979). Typical concentrations for most sites that are not heavily industrialized appear to range from trace levels to 22 ppb (Ohio River Valley Sanitation Commission 1980, 1982). Data from EPA s STORET database indicate that chloroform was detected in 64% of 11,928 surface water sample data points at a median concentration of 0.30 ppb (Staples et al. 1985). 

Nonurban oxidant measurements in Ohio were reported by Neligan and Angus. Concentrations of 0.18 and 0.12 ppm were reported for rural sites in Wilmington and McConnelsville, respectively. At the same time, urban sites had similar concentrations. However, the nonurban sites violated the ambient air quality standard more frequently than the urban sites. Trajectory analysis showed that ozone concentrations of 0.04-0.06 ppm were found in air masses that had not passed over anthropogenic hydrocarbon sources. These may have been examples of naturally occurring oxidant. Airborne hydrocarbon bag samples were obtained over 6-min... 

Matsumura and Bousch (1966) isolated carboxy lest erase (s) enzymes from the soil fungus Trichoderma viride und a bacterium Pseudomonas sp., obtained from Ohio soil samples, that were capable of degrading malathion. Compounds identified included diethyl maleate, desmethyl malathion, carboxylesterase products, other hydrolysis products, and unidentified metabolites. The authors found that these microbial populations did not have the capability to oxidize malathion due to the absence of malaoxon. However, the major degradative pathway appeared to be desmethylation and the formation of carboxylic acid derivatives. 

Meantime, it seemed worthwhile to examine some of the residues obtained from the commercial electrolysis of water for the production of oxygen, although the conditions under which commercial cells are operated are rather unfavorable, owing to the continual additions of fresh water to the cells. Through the courtesy of the Southern Oxygen Company of Alexandria, Va., and later of the Ohio Chemical Company of New York, samples of the residual solutions from cells continuously operated for two and three years, respectively, were secured. The hydrogen and oxygen from this water have been examined at Columbia University. 

The water distribution system in the city of Dayton, OH, uses Southdown concrete water mains to deliver water to its citizens. Routine sampling and testing of Dayton s water supply by the city s Department of Water consistently shows that the levels of metals are well below the Ohio EOA Community Drinking Water Standards, and that these levels have remained constant throughout a nine-year testing period from 1982 to 1990. Because metal leaching has not occurred, there is no reason for concern over the safety of Southdown concrete pipes to transport drinking water. 

Isolate NRC-1 and the SS-17 clone of NRC-1 of K, aeruginosa were cultured in BG-11 medium (9) They were kindly provided by Dr. W. W. Carmichael, Wright State University, Dayton, Ohio. A lyophilized sample of a toxic bloom of >1. aeruginosa collected from Kezar Lake, New Hampshire on October 10, 1978 was generously provided by Dr. J. J. Sasner, Jr., University of New Hampshire, Durham, New Hampshire. 

These authors also found that 65% (New York) and 67% (Ohio) of the sampled medicated patients who received an antipsychotic prescription were not diagnosed with a psychotic disorder. Similarly, 0% and 20% of the sampled medicated patients who received a stimulant medication were not diagnosed with ADHD, and 27% and 42% of the sampled medicated patients who received antidepressants were not diagnosed with major depression, dysthymia, bipolar disorder, or related conditions. In discussing the appropriateness of the medication treatments in the survey, the authors concluded that approximately 10% of the treatments in each sample were deemed inappropriate. 

When the cyclotron bombardment method became available, H. B. Law, M. L. Pool, J. D. Kurbatov, and L. L. Quill at Ohio State University bombarded samples of neodymium and samarium and obtained radioactive preparations which they believed might contain some 61 (18). C. S. Wu and E. Segre confirmed this (19). F. A. Paneth pointed out that they probably actually had obtained 61 in their mixtures, but the cyclotron method was not sufficiently powerful to give conclusive evidence of its existence (10). Nevertheless, the Ohio State group proposed the name cyclonium for the element.
