Physa acuta is a common pulmonale snail that inhabits streams, ponds and lakes throughout North America and has been used as an organism to obtain more information on the effects of ILs on aquatic environments. Four different classes of compounds have been considered, namely imidazolium, picolinium, ammonium and phosphonium salts. According to data published by Lamberti and co-workers [21] and summarised in Table 6 the most toxic IL to P. acuta was l-octyl-3-methylpyridinium bromide (LC50 =1.0 ppm) and the least toxic was tetrabutylammonium bromide (LC50 = 580.2 ppm).
