Marine aerosols are poorly characterized and may have a significant impact on air quality in coastal regions, as well as climate. These aerosols are formed through wave action in the ocean, releasing chemicals into the atmosphere in the form of gases or particles. Many of these chemicals are organic molecules, some of biological origin. Organic compounds can be toxic, bioaccumulative, or change the properties of the particles, which can, in turn, impact climate and air quality. The mechanism by which the ocean releases chemicals into the atmosphere is not well understood.

海洋气溶胶的特性很差，可能对沿海地区的空气质量和气候产生重大影响。这些气溶胶是通过海洋中的波浪作用形成的，以气体或颗粒的形式将化学物质释放到大气中。这些化学物质中有许多是有机分子，有些是生物来源的。 有机化合物可能是有毒的，生物累积性的，或者改变颗粒的性质，这反过来会影响气候和空气质量。海洋向大气中释放化学物质的机制尚不清楚。
