    Abstract

    Ultrafine particles sampled during new particle formation bursts observed in the coastal zone were studied with transmission electron microscopy (TEM) and elemental analysis using energy‐dispersive X ray (EDX).
    It was observed that both iodine and sulphur were present in the new particles with diameter below 10 mn.
    Gaseous emissions of halogen compounds from seaweeds were also measured at the same location during low‐tide particle nucleation episodes.
    Based on the presence of iodine in the particle phase during low‐tide nucleation bursts, and the significant emission of iodine compounds from the seaweeds during these periods, it is apparent that part of the biogenic iodine species emitted from the seaweeds end up in the ultrafine particulate phase. It was not possible to quantitatively determine the iodine content in the particles; however, in most cases the relative contribution from iodine and sulphate was similar, while some cases indicated no sulphate.
    On larger sized particles the contribution of sulphate was significantly higher than iodine. It appears that the condensable species leading to the appearance of new particles in the coastal atmosphere is an iodine species.
    Whether or not this iodine species also participates in the nucleation of new stable clusters could not be completely verified.
