Association of benzo(a)pyrene with dissolved organic matter: Prediction of Kdom from structural and chemical properties of the organic matter 总被引:1,自引:0,他引:1
The affinity of dissolved organic matter (DOM) for binding a polycyclic aromatic hydrocarbon, benzo(a)pyrene (BaP), was measured for 11 surface and ground waters and a commercial humic acid. The hydrophobic-acid (HbA) and hydrophobic-neutral (HbN) compositions of the DOM, solution absorptivity at 270nm (ABS270), and DOM molar volumes were determined. Waters enriched in HbA material had a larger molar volume and higher aromatic content (as indicated by the ABS270). There was a good correlation between the size and HbA content of the DOM from the different sources and the Kdom for binding BaP. An excellent predictive relationship (r2 = 0.9) was demonstrated between the ABS270 of a water and the Kdom for binding BaP. Based on these results, it is suggested that binding of BaP to DOM depends not only on the hydrophobicity of DOM, but also on the existence of an open structure within the DOM to provide access of the aqueous solute to hydrophobic domains within the DOM. 相似文献

This research examined whether trainee demographics and pre‐training competence predicted participation in voluntary diversity training. Results indicate that demographic variables had no impact on interest in training (Study One) or on actual training participation (Study Two). However, pre‐training competence levels had a positive effect on both outcomes. More competent trainees expressed more interest in additional training (Study One) and were more likely to attend a voluntary training session (Study Two). The authors suggest that trainees with low competence in the diversity domain are unaware of their low competence levels and therefore are not motivated to participate in training programs designed to increase diversity competence. Implications of these findings for organizations offering voluntary diversity training are discussed. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

Surveys of juvenile hawksbills around Buck Island Reef National Monument, US Virgin Islands from 1994 to 1999 revealed distributional patterns and resulted in a total of 75 individual hawksbill captures from all years; turtles ranged from 23.2 to 77.7 cm curved carapace length (CCL; mean 42.1 ± 12.3 cm SD). Juveniles concentrated where Zoanthid cover was highest. Length of time between recaptures, or presumed minimum site residency, ranged from 59 to 1,396 days (mean 620.8 ± 402.4 days SD). Growth rates for 23 juveniles ranged from 0.0 to 9.5 cm year?1 (mean 4.1 ± 2.4 cm year?1SD). Annual mean growth rates were non-monotonic, with the largest mean growth rate occurring in the 30–39 cm CCL size class. Gastric lavages indicated that Zoanthids were the primary food source for hawksbills. These results contribute to our understanding of juvenile hawksbill ecology and serve as a baseline for future studies or inventories of hawksbills in the Caribbean. 相似文献
