Metal dissolution from atmospheric aerosol deposition to the oceans is important in enhancing and inhibiting phytoplankton growth rates and modifying plankton community structure, thus impacting marine biogeochemistry. Here we review the current state of knowledge on the causes and effects of the leaching of multiple trace metals from natural and anthropogenic aerosols. Aerosol deposition is considered both on short timescales over which phytoplankton respond directly to aerosol metal inputs, as well as longer timescales over which biogeochemical cycles are affected by aerosols.

大气气溶胶沉积到海洋中导致的金属溶解对促进和抑制浮游植物生长速率以及改变浮游生物群落结构非常重要，从而影响海洋生物地球化学。在这里，我们综述了目前对从天然和人为气溶胶中浸出多种痕量金属的原因和影响的认识。气溶胶沉积被认为既有在浮游植物对气溶胶金属输入直接作出反应的短时间尺度上，也有在受气溶胶影响的生物地球化学循环的较长时间尺度上。
