摘要
Transmission of microplastics(MPs)through aerosolization has been recently realized as an important route.Inspite of the reports of the ubiquitous MP presence in aerosols,the spatio-temporal information is inadequate and has very limited practicality in assessing if aerosol can be a significant source of MPs to the marine environment.Data on marine contribution to atmospheric MPs is exceptionally scarce,and the ocean-air exchange is considered an emerging research area.Evidence of MPs entering the oceans via atmospheric deposition has been recently produced.The idea of ocean-air exchange emanates from the fact that beach sediments can get suspended under sand and dust storms,bubble bursts and sea sprays due to wind and waves in surf zones can lead to the ejection of particles into aerosols.In this succinct review,we have tried compiling the data on atmospheric MPs that can shed some light on the flux from and to the aquatic environment.While the information is too limited never the less its incorporation into the marine MP cycle cannot be neglected.
