Fluorine can flow into the environment after leakage or spill accidents and these excessive amounts can cause adverse effects on terrestrial ecosystems. Using three media (filter paper, soil, and filter-paper-on-soil), we investigated the toxic effects of fluorine on the germination and growth of crops (barley, mung bean, sorghum, and wheat), on the activities of soil exoenzymes (acid phosphatase, arylsulfatase, fluorescein diacetate hydrolase, and urease) and on the survival, abnormality, and cytotoxicity of Eisenia andrei earthworms. The germination and growth of crops were affected by fluorine as exposure concentration increased. The activities of the four enzymes after 0-, 3-, 10-, and 20-day periods varied as exposure concentration increased. According to in vivo and in vitro earthworm assays, E. andrei mortality, abnormality, and cytotoxicity increased with increasing fluorine concentration. Overall, fluorine significantly affected each tested species in the concentration ranges used in this study. The activities of soil exoenzymes were also affected by soil fluorine concentration, although in an inconsistent manner. Albeit the abnormally high concentrations of fluorine in soil compared to that observed under natural conditions, its toxicity was much restrained possibly due to the adsorption of fluorine on soil particles and its combination with soil cations.

泄漏或溢漏事故发生后，氟会流入环境，这些过量的氟会对陆地生态系统造成不利影响。我们使用三种介质（滤纸，土壤和土壤滤纸）研究了氟对农作物（大麦，绿豆，高粱和小麦）的发芽和生长对土壤活性的毒害作用外切酶（酸性磷酸酶，芳基硫酸酯酶，荧光素二乙酸酯水解酶和脲酶）以及艾氏ise的存活，异常和细胞毒性。随着暴露浓度的增加，农作物的发芽和生长受到氟的影响。0、3、10和20天后四种酶的活性随暴露浓度的增加而变化。根据体内和在体外earth试验中，E。andrei的死亡率，异常性和细胞毒性随着氟浓度的升高而增加。总体而言，在本研究中使用的浓度范围内，氟对每种受试物种均具有显着影响。土壤外酶的活性也受到土壤氟浓度的影响，尽管方式不一致。尽管与在自然条件下观察到的相比，土壤中氟的浓度异常高，但由于氟在土壤颗粒上的吸附以及与土壤阳离子的结合，其毒性受到了很大的限制。
