| 目的 探索干片采样法在海滩大气氯离子监测中的应用。方法 针对海南海滩大气氯离子监测过程中出现的饱和现象，分析其形成的原因和影响因素，提出制定监测方案的应对措施，以及测试结果的表征方法。结果 A地区的1号、2号采样点和万宁站海洋平台采样时间为7天、19天的氯离子监测存在饱和现象，3号采样点3个采样周期的监测都没有出现饱和现象。结论 海滩大气环境中，海浪高度与空气中氯离子的沉降速率有较强的关联性。缩短采样时间，增加采样次数，适当增加平行样数量和监测点的数量，可降低饱和现象监测结果的影响。A地区海滩氯离子的沉降速率为7.61 mg/(100 cm2•d)，万宁站海滨的氯离子的沉降速率可确定为大于5.99 mg/(100 cm2.d)。 |

| Objective To explore application of dry plate sampling method in monitoring Cl- in beach atmosphere. Methods In view of the saturation phenomenon of Cl- monitoring in Hainan beach, reasons and influencing factors were analyzed, corresponding measures on making monitoring plans were put forward, and characterization methods of the test results were also presented. Results Saturation occurred during the 7 days and 19 days of Cl- monitoring at sampling point 1 and 2 of Area “A” and the offshore platform of Wanning station. There was no saturation at sampling point 3 in the 3 sampling periods. Conclusion In the atmospheric environment of the beach, there is a strong correlation between wave height and deposition rate of Cl- in the air. Reducing the sampling time, increasing the number of samples, appropriately increasing the number of parallel samples and the number of monitoring points can reduce influences of monitoring results of saturation phenomenon. The sedimentation rate of Cl- is 7.61 mg/(100 cm2•d) in the beach of area “A”. The sedimentation rate of Cl- can be determined to be greater than 5.99 mg/(100 cm2•d) in the beach of Wanning station. |
