94,536 | Dose concepts for inhaled vapors and gases | Dahl, AR | 1,990 | "Dose" for any toxicant is a shifting concept; thus, there is a frequent need for modifiers such as "administered" or "effective," when referring to dose. When applied to inhaled gases and vapors, "dose" is even more vague. The wide range of physicochemical properties associated with gases and vapors, the different tar... | 0 |

Cotton (Gossypium hirsutum L.) cultivars differ in degree of determinance, which may affect cul... | 0 |

43,597 | The relationship between foliar injury, nitrogen metabolism, and growth parameters in ozonated soybeans | Smith, G; Neyra, C; Brennan, E | 1,990 | A single 12 h ozone exposure peaking at 0.20 ppm proved phytotoxic to greenhouse-grown 'Cutler 71' soybeans at each growth stage tested from V5 to R6. Visible injury occurred within 40 h on the unifoliodate leaves and middle-aged and older trifoliolates while the younger leaves were free from toxicity symptoms. In some... | 0 |
4,765 | Kinetics and nitro-products of the gas-phase OH and NO3 radical-initiated reactions of naphthalene-d8, fluoranthene-d10 and pyrene | Atkinson, R; Arey, J; Zielinska, B; Aschmann, SM | 1,990 | The kinetics and nitroarene product yields of the gas-phase reactions of naphthalene-d8, fluoranthene-d10, and pyrene with OH radicals in the presence of NOx and in N2O5NO3NO2air mixtures have been investigated at 296 ? 2 K and atmospheric pressure of air. Using a relative rate method, naphthalene-d8 was shown to reac... | 0 |
55,274 | Crystal occurrence and wax disruption on leaf surfaces of cabbage treated with simulated acid rain | Adams, CM; Caporn, SJM; Hutchinson, TC | 1,990 | Epicuticular waxes on leaves of Brassica oleracea L. (cabbage) were studied using scanning electron microscopy after a single treatment with simulated rain of pH 5A6, 3A0 or 2A5 which was either sprayed on to plants in an exposure chamber or applied as droplets with a micropipette. Treatments with acidified rain caused... | 0 |
57,615 | Association of nonmelanoma skin cancer and actinic keratosis with cumulative solar ultraviolet exposure in Maryland watermen | Vitasa, BC; Taylor, HR; Strickland, PT; Rosenthal, FS; West, S; Abbey, H; Ng, SK; Munoz, B; Emmett, EA | 1,990 | #To establish the relationship between ultraviolet-B radiation and squamous cell carcinoma (SCC), basal cell carcinoma (BCC), and actinic keratosis (AK), a cross-sectional prevalence survey was performed in a sample of 808 white, male watermen 30 years of age and older residing in the Eastern Shore of Maryland. A measu... | 0 |
777,096 | Exposure of cottonwood plants to ozone alters subsequent leaf decomposition | Findlay, S; Jones, CG | 1,990 | Cottonwood saplings were exposed to ozone or charcoal-filtered air in a closed chamber. After leaf abscission, decomposition of individual leaf discs was measured in containers of stream water. Exposure of plants to 200 ppb ozone for 5 h caused early leaf abscission and changes in the chemical composition of leaves at ... | 0 |
54,109 | Determination of photochemically produced hydroxyl radicals in seawater and freshwater | Zhou, X; Mopper, K | 1,990 | A variety of short-lived, reactive chemical species (i.e. free radicals and excited state species) are known to be photochemically produced in natural waters. Some of these transients may strongly affect chemical and biological processes, and they have been implicated in the degradation of organic pollutants and natura... | 0 |
25,242 | Geographic variation in breast cancer mortality in the United States: A hypothesis involving exposure to solar radiation | Garland, FC; Garland, CF; Gorham, ED; Young, JF | 1,990 | Epidemiologic and laboratory evidence suggests that vitamin D may play a role in reducing breast cancer risk. Lack of exposure to ultraviolet sunlight can increase the prevalence of vitamin D deficiency. This deficiency may place some populations at higher risk for breast cancer. The association between total average a... | 0 |
27,406 | Biochemical basis of ozone toxicity | Mustafa, MG | 1,990 | Ozone (O3) is the major oxidant of photochemical smog. Its biological effect is attributed to its ability to cause oxidation or peroxidation of biomolecules directly and/or via free radical reactions. A sequence of events may include lipid peroxidation and loss of functional groups of enzymes, alteration of membrane pe... | 0 |
