Quantum dots (QDs), such as cadmium selenide (CdSe) and lead selenide (PbSe) exhibit excellent optical, magnetic and chemical properties due to their extremely size (ca. 1-10 nm) and are attractive semiconductor nanomaterials for optical studies and energy storage. In this study, aqueous synthesis of CdSe and PbSe QDs in a size range of 2-10 nm was described. Synthesized QDs were characterized using SEM and TEM, DLS, zeta potential, FTIR, EDX and XRD. Highest accumulation (72.5 ± 5.8 mg L) of PbSe QDs occurred at 10 ppm suspensions. In general accumulation increased up to 48 h exposure then fluctuate tended to decline. For CdSe QDs, accumulation tended to decrease for 72 h exposure except that for 5 ppm groups. For the elimination period, in general, the elimination levels of PbSe and CdSe QDs from exposed individuals decreased (p < 0.05) even it has some fluctuate.
量子点（QD），如硒化镉（CdSe）和硒化铅（PbSe），由于其极其微小的尺寸（约 1-10nm）而表现出优异的光学、磁学和化学性质，是用于光学研究和能量存储的有吸引力的半导体纳米材料。本研究描述了在 2-10nm 范围内的 CdSe 和 PbSe QD 的水相合成。使用 SEM 和 TEM、DLS、zeta 电位、FTIR、EDX 和 XRD 对合成的 QD 进行了表征。在 10ppm 悬浮液中，PbSe QD 的最高积累量（72.5±5.8mg L）。一般来说，暴露 48 小时后，积累量增加，然后波动趋于下降。对于 CdSe QD，除了 5ppm 组外，72 小时暴露的积累量趋于减少。在消除期，一般来说，暴露个体中 PbSe 和 CdSe QD 的消除水平下降（p<0.05），即使有一些波动。
