并网太阳能光伏发电是目前全球发展最快的发电技术之一。虽然光伏技术在使用过程中具有零排放的环境效益，但薄膜光伏电池中重金属的使用引起了有关光伏板报废处理的重要健康和环境问题。迄今为止，尚无针对垃圾填埋场处置的碲化镉 (CdTe) 光伏电池板中镉浸出所造成的潜在人类健康风险的定量评估。因此，我们使用筛查级风险评估工具来估计与将 CdTe 面板处置到垃圾填埋场相关的可能的人类健康风险。此外，我们对回收过程中潜在的镉释放量进行了文献综述，以对比垃圾填埋场处置光伏电池板与回收光伏电池板的潜在健康风险。根据我们的文献综述结果，目前无法进行有意义的风险比较。根据对光伏电池板处置产生的人类健康风险估计，我们的评估表明，以目前的产量，CdTe 电池板的垃圾填埋处理不会对人类健康造成危害，尽管我们的结果指出了 CdTe 光伏电池板报废管理的重要性。 (C) 2014 Elsevier Ltd. 保留所有权利。
Grid-connected solar photovoltaic (PV) power is currently one of the fastest growing power-generation technologies in the world. While PV technologies provide the environmental benefit of zero emissions during use, the use of heavy metals in thin-film PV cells raises important health and environmental concerns regarding the end-of-life disposal of PV panels. To date, there is no published quantitative assessment of the potential human health risk due to cadmium leaching from cadmium telluride (CdTe) PV panels disposed in a landfill. Thus, we used a screening-level risk assessment tool to estimate possible human health risk associated with disposal of CdTe panels into landfills. In addition, we conducted a literature review of potential cadmium release from the recycling process in order to contrast the potential health risks from PV panel disposal in landfills to those from PV panel recycling. Based on the results of our literature review, a meaningful risk comparison cannot be performed at this time. Based on the human health risk estimates generated for PV panel disposal, our assessment indicated that landfill disposal of CdTe panels does not pose a human health hazard at current production volumes, although our results pointed to the importance of CdTe PV panel end-of-life management.
