Tossicità dei fluoruri disciolti in acqua e loro effetti sulla gametogenesi di Branchiura sowerbyi, Beddard (OLIGOCHAETA,TUBIFICIDAE) [PDF]
Lo scopo di questa ricerca è di valutare gli effetti tossici dei fluoruri sull’Oligochete Branchiura sowerbyi, analizzandone il tasso di mortalità e il bioaccumulo, inteso come la concentrazione dell’inquinante presente nei tessuti dell’animale.

Branchiura sowerbyi Reared in Two Sediments for Ecotoxicological Bioassays
The present work compared the survival, growth, and reproduction of Branchiura sowerbyi reared in natural sediment and in artificial tropical sediment (composed of sand, clay, and coconut fibers). The artificial tropical sediment, in the tested composition, appeared not to be suitable for conducting bioassays with this species, since the results showed
