Oxybenzone (OBZ), avobenzone (AVB), octocrylene (OCR) and octinoxate (OMC) are ultraviolet (UV) filters commonly added to chemical sunscreens. These UV filters are known to widely contaminate the environment through a variety of anthropogenic sources, including sewage discharge. However, systematic studies of the damage caused by these four UV filters and their toxicopathological differences in a variety of plant species are lacking. In this study, we demonstrated that irrigation with water containing these four UV filters could significantly inhibit the aboveground growth of cucumber plant. All of the UV filters decreased photosynthesis through nonstomatal factors but via different inhibitory mechanisms. Only OBZ inhibited photosynthesis by directly inhibiting photosynthetic electron transport, while the other three (AVB, OCR, and OMC) inhibited photosynthesis by inhibiting the Calvin-Benson cycle. Additionally, these four UV filters also decreased plant respiration under long-term treatment. Photosynthesis and respiration inhibition led to the over production of reactive oxygen species (ROS) and the formation of lipid peroxidation damage products, which further damaged the structure and function of plant cells, causing secondary pathologies and potentially leading to reduced crop yields. The study also demonstrated that these four UV filters caused different degrees of phototoxic damage to cucumber plants. On the basis of comprehensive evaluation, we speculated that the order of the four UV filters in terms of plant damage was OBZ > AVB > OMC > OCR. Because of the severe damaging effects of these UV filters on plant growth, the application of contaminated biosolids/reclaimed water in agriculture reduces agricultural production and may damage ecosystems. The results of this study can advance recognition of the hazards associated with environmental and agricultural pollution via UV filters and encourage consumers and the industry to limit or reduce the application of cosmetics and over-the-counter drugs containing these substances.

氧苄酮，阿伏苯宗，辛二烯和辛氧酸酯防晒成分对黄瓜植物（黄瓜）的毒理作用比较。

氧苯甲酮（OBZ），阿伏苯宗（AVB），辛二烯（OCR）和辛辛酸酯（OMC）是通常添加到化学防晒霜中的紫外线（UV）过滤器。已知这些紫外线过滤器会通过各种人为来源广泛污染环境，包括污水排放。但是，缺乏对这四种紫外线过滤剂造成的损害及其在多种植物物种中的毒理病理学差异的系统研究。在这项研究中，我们证明了用包含这四个紫外线过滤剂的水灌溉可以显着抑制黄瓜植物的地上生长。所有的紫外线过滤剂都通过非气孔因子但通过不同的抑制机制降低了光合作用。只有OBZ通过直接抑制光合作用的电子传输来抑制光合作用，而其他三个（AVB，OCR，和OMC）通过抑制Calvin-Benson循环来抑制光合作用。此外，这四个紫外线过滤器在长期处理下还降低了植物的呼吸作用。光合作用和呼吸抑制导致活性氧（ROS）的过量生产和脂质过氧化损伤产物的形成，这进一步破坏了植物细胞的结构和功能，导致了继发性病理，并有可能导致农作物减产。研究还表明，这四种紫外线过滤剂对黄瓜植物造成了不同程度的光毒性损害。在综合评估的基础上，我们推测四个紫外线过滤器对植物的损害顺序为：OBZ> AVB> OMC> OCR。由于这些紫外线过滤剂对植物的生长具有严重的破坏作用，在农业中使用受污染的生物固体/再生水会降低农业产量并可能破坏生态系统。这项研究的结果可以通过紫外线过滤器提前识别与环境和农业污染相关的危害，并鼓励消费者和行业限制或减少化妆品和含有这些物质的非处方药的使用。
