Harmar Pond Sediment Core Metals

A sediment core was collected from a small urban pond in Harmar Township, Pennsylvania. Half centimeter intervals of the sediment core were digested using 6mL of 10% (vol/vol) sub-boil distilled trace metal grade nitric acid. Sediment metals were measured to better understand the history of metal contamination in the Pittsburgh region.研究人员从宾夕法尼亚州哈马镇（Harmar Township）的一处小型城市池塘采集了沉积物岩芯（sediment core）。以0.5厘米为间隔对该沉积物岩芯进行分段消解处理，所用消解试剂为6毫升体积分数为10%（vol/vol）的亚沸蒸馏痕量金属级硝酸。通过测定沉积物中的金属含量，以更好地了解匹兹堡地区的金属污染历史。
