Triturus

Newt, Triturus cristatus, adults, held in tank with a zinc-plated base South African clawed frog, Xenopus laevis 200 to 3000 overa 7-day period Zinc-poisoned newts were lethargic, ate poorly, and had skin darkening prior to death. Zinc residues were elevated in kidney, brain, liver, and intestine, when compared to controls. The hippocampus region of the brain of poisoned newts contained zinc-rich cells 82...

The most common newts cf temperate parts of Eurasia are animals in the genus Triturus, for example, the smooth newt Triturus vulgaris), the crested newt T. cristatus), and the alpine newt T. alpestris). These newts do not have an eft st e, althor the adults may spend some time on land. The mountain newts Euproctus sjp.) ate another European group of newts.

Pacces Zaffaroni et al. (1978) investigated the percutaneous toxicity of maneb in solution to the adult newt, Triturus cristatus. When incubated in water containing 20, 40, 60, 80, or 100 ppm maneb, the newts suffered deaths in a dose-dependent fashion, with 50% of the male newts dead in 8.4—8.8 hours at 100 ppm and in 255 hours at 20 ppm. The females were not as susceptible to the lethal action of the fungicide, with 50% dying in 28.5 hours at 100 ppm, and some newts still alive after 5 months at 20 ppm. No studies were located concerning death following dermal exposure of animals to mancozeb.
