Pelagic organisms

The receptors of interest included pelagic organisms, benthic organisms and marine mammals (dolphins/porpoises). For the pelagic and benthic organisms, ecological risk assessment was conducted at the population level. For the dolphins and porpoises, risk assessment was conducted at the organism level.

The data of Cloud and Licari (1968) support La Berge s conclusions. Spherical structures 4-10 fim in size, similar to Huroniospora , are found even in the very old rocks of the Soudan BIF. In the Proterozoic formations of Gunflint and Biwabik (Lake Superior) and in the Pretoria series (South Africa), spherical forms which probably were pelagic organisms living in the water layer near the bottom of the photozone are extensively developed in the banded iron-formations. 

A high spectral resolution and sensitivity is probably common in most pelagic organisms, but again special interest has been devoted to the freshwater cladoceran Daphnia. For Daphnia, sensitivity to UVR was suggested in the early works of Koehler [10] and Merker [11] as cited in Smith and Macagno (1990)...
