Vapour-Particle Phase Interactions of Some Selected Persistent Organic Pollutants in the Marine Atmosphere
Unlike the majority of inorganic compounds, many organic chemicals have significant vapour pressures at ambient temperatures. Consequently, organic compounds are frequently transported within the environment at least partially in the vapour phase. The nature of the relationship between this vapour, the solid and liquid aerosol and the dissolved phase is therefore crucial to an understanding of how such chemicals migrate within the environment. In their major review of atmospheric input of trace species to the oceans Duce et al. (1991) highlighted both the complexity of the atmospheric transport processes and the general paucity of data. They compiled a summary of the mean concentrations of chlorinated organic contaminants for the major ocean basins which is reproduced in Table 7.1.
