We analyzed the accumulation of inorganic and organic toxicants in tadpoles from nine populations of the common frog (Rana temporaria) at different altitudes of the Hohe Tauern National Park in Austria). Lead and cadmium concentrations in tadpoles increased with the acidity and metal-to-HCO3(-) ratio in the water exceeding those found in tadpoles from agricultural areas. Organochlorines (DDTs, polychlorinated biphenyls, lindane) and polyaromatic hydrocarbons were present in all of the populations, but only DDTs accumulated significantly compared with the concentrations in their diet.
我们分析了奥地利霍赫陶恩国家公园不同海拔高度的九个普通青蛙（林蛙）种群蝌蚪体内无机和有机毒物的积累情况。蝌蚪体内铅和镉的浓度随着水中酸度以及金属与碳酸氢根离子（HCO3(-)）的比例增加而升高，超过了农业地区蝌蚪体内的浓度。所有种群中均存在有机氯（滴滴涕、多氯联苯、林丹）和多环芳烃，但与它们食物中的浓度相比，只有滴滴涕有显著积累。
