I've not heard of anything but saxitoxin (the usual red tide toxin) being concentrated enough on occasion to pose a danger from aerosols in sea water. (Maybe someone else can contribute more info.) Of course, now we have pfiesteria toxin aerosols being dangerous in river and estuarine areas. Re toxin origins, there is some evidence accumulating that many if not all of these marine toxins are actually elaborated by bacteria living in various symbiotic relationships with the algae.
