    Notes: Sorption/desorption studies of VCM in the systems PVC/VCM/water, PVC/VCM/corn oil an PVC/VCM/heptane were carried out. At low VCM concentrations, classical curves are obtained, where the sorption isotherms are located below their desorption counterparts. Above a certain VCM concentration a crossover exists and an inversion of the curves occurs. It was suggested that the intersection between the curves represents the point where all the active sites in the polymeric matrix are occupied by monomer molecules. The negative values of the total Gibb's free energy and the energy of mixing in the polymer were found to increase with the decrease in monomer concentration pointing out to the possibility that at low enough monomer concentrations no migration of VCM into the contained food from a PVC package may occur.

    Notes: Abstract Cabbage, beets, green beans, and butternut squash were grown in control and municipal sewage sludge-treated experimental plots. Freezedried edible portions of each vegetable fed at 25% of the diet to male Fischer rats for 12 weeks, indicated no differences in dietary intake or weight gain, nor were there any differences in blood levels of alpha-fetoprotein, a marker for hepatic preneoplastic transformation. Sludge-grown vegetables did not cause any differences in relative liver weight or in activity of the hepatic mono-oxygenases, aminopyrene-N-demethylase, orp-nitroanisole-O-demethylase, when compared to the same vegetable grown on control soil. There were no effects attributable to the sewage sludge treatment on liver cell ultrastructure. The level of cadmium in the kidneys of rats fed sludge-grown beets was twice that of the controls. The results of mutagenesis testing withS. typhimurium and microsomes (S-9) activation indicated a positive dose response with extracts of sludge-grown beans and in the urine of rats consuming sludge-grown beets. Although no overt toxicologic responses were observed in rats fed sludge-grown vegetables, these positive mutagenic changes create uncertainties in evaluation of potential risks involved in using municipal sludge on food-producing land.

    Concentrations of some ionic species in Central Long Island, New York precipitation in relation to meteorological variables (1982)

    Notes: Abstract Three years of hourly sequential precipitation data from central Long Island, New York were analyzed to determine the concentrations of major anions and cations and their relationships to each other and to meteorological conditions. Findings with respect to sulfate, nitrogen in nitrate plus nitrite, nitrogen in ammonium, chloride and sodium ions and selected ratios are reported here. Concentrations of each of the first three species were highly correlated with concentrations of the others and with hydrogen ions. Little correlation was found between these species and either sodium or chloride ions but the latter two were highly correlated with each other. Concentrations of the first three species are highest in summer and lowest in winter. High concentrations were also found with cold front and squall line precipitation and with rain showers and thundershowers. Concentrations of these species are high with both low and high precipitation rates. Concentrations are highest with west and northwest winds due to the presence of major source regions in those directions. They are high with both low and high temperatures but lower in the moderate temperature range. Concentrations are high with low (3.0 to 3.9) and with high (6.0 to 6.9) pH but less at intermediate levels. Thus, concentrations of these species in precipitation are determined by complex chemical and meteorological interactions and relationships. Chloride and sodium were found to be largely of marine origin. Highest concentrations occur in the fall and with hurricanes, strong winds, and onshore wind directions. Concentrations decrease with increasing precipitation rate. At low concentrations, the chloride/sodium ratio is above the seawater ratio and excess chloride is present. At high concentrations the ratio is below the seawater ratio and a chloride deficit exists.

    Effects of varying air trajectories on spatial and temporal precipitation chemistry patterns (1982)
    Springer
    Water, air & soil pollution 18 (1982), S. 173-189

    Notes: Abstract This study was designed to determine if judicious use of synoptic data and an operational trajectory model could identify probable source regions of anthropogenic pollutants in northeastern United States precipitation and thus relate receptor measurements to emissions data without consideration of the complex intervening meteorological and chemical processes. The storm event of April 8 to 10, 1979, was selected for intensive study. Precipitation chemistry data were obtained from event samples at six MAP3S sampling sites and from hourly samples at Brookhaven National Laboratory. Concentrations of hydrogen, sulfate, nitrate and ammonium ions were used as receptor data. Some emissions data for SOx and NOx were obtained from the MAP3S emissions inventory. Surface and upper air meteorological data were analyzed. Backward trajectories ending at each of the sampling sites during the precipitation period were computed with the Heffter Interactive-Terminal Transport Model using selected transport layers. Results show that concentrations of pollutant species in event precipitation samples were much higher at stations at end points of trajectories passing through the Ohio River valley than at stations with other trajectories. Likewise, concentrations at Brookhaven were much higher during the end period of a trajectory through the same region than with more northerly and more southerly tracks. The model produced back trajectories consistent with synoptic flows. Concentrations of air pollutants in precipitation were roughly proportional to the number of major pollutant sources along the trajectory. These results suggest that a larger number of studies might identify more restricted source areas or even establish a quantitative relationship between source emissions along a trajectory and concentrations in precipitation at receptor sites.

    Maternal and child health (1982)

    Notes: Abstract The United States has achieved dramatic improvements in overall maternal and child health status, yet faces disturbingly wide variations in the health status of many population subgroups. The Surgeon General in 1980 published specific quantitative objectives to stimulate further improvements in the health of the American people by 1990. A critical step in meeting relevant objectives is the more effective use at national, state, and local levels of available data, particularly infant, perinatal, neonatal, and maternal mortality rates and the incidence of low weight births. This paper reviews variations in infant mortality rates and five current federal “categorical” programs that aim to improve maternal and child health: Supplemental Feeding Program for Women, Infants and Children; Head Start; Maternal and Child Health; Family Planning; and Community Health Centers. Several examples are cited of effective use of data in the coordination and targeting of resources from these large public programs. Recommendations are made for enhancement of federal maternal and child health programs within current funding levels. These recommendations will be all the more relevant if the Congress enacts block grants to the states with lower total funding.
