摘要: The study of fluvial bed sediments is essential for deciphering the impact anthropogenic activities on water quality and drainage basin integrity. In this study, a systematic sampling design was employed to characterize spatial variation lead (Pb) concentrations in sediment urban streams Palolo basin, southeastern Oahu, Hawaii. Potentially bioavailable Pb assessed with dilute 0.5 N HCl extraction Pukele (19) > Waiomao (8). Comparisons guidelines potential toxicity estimates using logistic regression model (LRM) indicated significant risk Stream bottom-dwelling organisms.
