我们研究了四种不同藻类释放的有机物对实验室产生的海洋气溶胶颗粒的吸湿生长和液滴活化行为的影响。与氯化钠或不含海洋表面活性剂的人造海水相比，用于活化的吸湿生长因子和干直径减少了不到10%。观察到人造海水的浓度依赖性非理想行为。但在测量不确定度范围内，含有有机物的样品测得的吸湿生长和液滴活化行为与亚饱和和过饱和测量点之间恒定的吸湿性参数一致。此外，3 秒后和 10 秒后测量的水合颗粒的吸湿生长相似，这意味着在该时间范围内没有检测到动力学效应。
We examined the effect of organic matter released by four different algal species on the hygroscopic growth and droplet activation behaviour of laboratory-generated marine aerosol particles. Hygroscopic growth factors and dry diameters for activation were reduced by less than 10%, compared to that of sodium chloride or of artificial seawater that was devoid of marine surfactants. Concentration-dependent nonideal behaviour was observed for the artificial seawater. But within measurement uncertainty, the measured hygroscopic growth and droplet activation behaviour for the samples that contained organic matter were consistent with a hygroscopicity parameter that was constant between the sub-and supersaturated measurement points. Also, the hygroscopic growth measured for hydrated particles after 3 and after 10 seconds was similar, which implies that in this time range no kinetic effects were detected.
