Given ubiquitous human exposure to ethylene oxide (EO), regardless of occupation or geography, the current risk-specific concentrations (RSCs: 0.0001–0.01 ppb) from the U.S. Environmental Protection Agency (EPA) cancer risk assessment for EO are not useful metrics for managing EO exposures to the general U.S. population. The magnitude of the RSCs for EO are so low, relative to typical endogenous equivalent metabolic concentrations (1.1–5.5 ppb) that contribute ~93% of total exposure, that the RSCs provide little utility in identifying excess environmental exposures that might increase cancer risk. EO monitoring data collected in the vicinity of eight EO-emitting facilities and corresponding background locations were used to characterize potential excess exogenous concentrations. Both 50th and 90th percentile exogenous exposure concentrations were combined with the 50th percentile endogenous exposure concentration for the nonsmoking population, and then compared to percentiles of total equivalent concentration for this population. No potential total exposure concentration for these local populations exceeded the normal total equivalent concentration 95th percentile, indicating that excess facility-related exposures are unlikely to require additional management to protect public health.

Serum Bilirubin Concentration

If kernicterus develops in an infant due to high serum bilirubin, low reserve albumin, and acidosis, bilirubin acid will also be deposited in the skin. In consequence, it seems possible that the yellow colour of the skin is correlated with that of the brain, to the extent that bilirubin deposition in the skin has occurred by precipitation of bilirubin acid. If so, the intensity of the yellow colour of the skin may be a somewhat better predictor of brain damage than the serum bilirubin concentration and measurement of the colour of the skin may theoretically be of clinical utility.

The breakdown of potato planting material is a serious problem in southern Queensland, particularly where cut seedpieces are used. Some growers use captan (50 g kg-1) or zineb (40 to 200 g kg-1) dusts to reduce losses, but the values of these treatments have not been accurately assessed. A number of chemicals were compared with a standard zineb (80 g kg-1) treatment and no treatment under field conditions. While zineb significantly reduced breakdown in four of eight experiments, mancozeb at equivalent concentration was significantly better in three of four experiments. Mancozeb at 400 g kg-1 was significantly better again than the lower concentration. The 400 g kg-1 concentration of mancozeb was evaluated on three seed consignments for effect on plant stand and yield. The number of plants that emerged was increased by 29%, with a 34% increase in yield. The increase in yield over what could be expected from improved numbers of plants is attributed to the control of wilt diseases and prevention of early crop senescence, which followed the prevention of basal stem rot by retention of seedpieces.

Inhibition Of Glycolysis

Oxalate was found to inhibit glycolysis in red blood cells during storage at 5 °C. The inhibition of glycolysis in blood cells by oxalate is reversible. The glycolytic activity of the oxalated cells can be restored by washing the cells, or by precipitating the oxalate with an equivalent concentration of added calcium ions. However, with increased duration of storage prior to removal of oxalate the rate of glycolysis in the erythrocytes was found to be decreased on removal of the oxalate.

Micrococcus varians ssp. halophilus ATCC 21971 showed abundant growth in complex media containing 1 M NaCl, NaBr, NaI, NaNO3, Na2SO4, KCl, KBr, KI, or KNO3, and 2 M RbCl or RbBr at 30 °C.Spontaneous mutants were isolated which were able to grow in a medium of 1.5 M LiCl (strain Li-5) or 2.5 M CsCl (strain Cs-7-Cs). Determination of cell-associated cation concentration at the exponential phase of growth showed that the cells contained monovalent cations of almost equivalent concentration as that in the medium: 0.570 m Li+ + 0.951 m Na+ in 1.5 M LiCl grown cells; 2.88 m Na+ in 3.0 M NaCl grown cells; 2.66 m K+ in 3.0 M KCl grown cells; 1.57 m Rb+ in 2.0 M RbCl grown cells; 1.44 m Cs+ in 1.5 M CsCl grown cells.
