Acid extractable elements. Concentration of elements extracted in 1N HCl (=HCl) (based on total µg extracted normalized to sediment weight), bulk sediment concentration (=TOT), and the ratio of the two (H/T). Abcissa is site sampled in 1989; ordinate is the concentration in ppm (µg/g) of HCl or TOT or H/T ratio. Some of the concentrations are scaled (÷10 or ÷100) for graphing. See Table 1 for site abbreviations. |
