摘要：Although bioaccumulation-related concepts are important scientificknowledge, a study on whether high school textbooks include appropriateexplanations has not been conducted. The present study investigated science andbiology textbooks from Korea, Japan, and the U.S., focusing on howbioaccumulation-related concepts were defined, what types of bioaccumulativesubstances were discussed, and the properties of these substances. The textbooksof these countries tended to focus on biomagnification. While the textbooks fromJapan and the U.S. present synthetic organic compounds as examples ofbioaccumulative substances, metallic substances were used as examples in allKorean textbooks. However, the discussion about the properties ofbioaccumulative substances was brief in the textbooks. Moreover, thebioaccumulative properties of metals and organic compounds were notdistinguished. The limited explanations in the textbooks might cause students tohave misconceptions about the processes of bioaccumulation andbioaccumulative substances, and negative perceptions toward essential tracemetals.
