The sea urchins Paracentrotus lividus and Arbacia lixula have a key role in benthic
dynamics and they are often used to assess the toxicity of environmental contaminants. The …

Bioassays with sea urchin embryos are widely used to define the environmental quality of
marine waters. Anomalies during embryogenesis are generally considered as end-points …

The aim of this research was to generate data on the mechanisms of toxicity of copper [Cu (4–
12 µg/L)] and nickel [Ni (33–40 µg/L)] during continuous sublethal exposure in seawater (32 …

Since the massive population decline of the long-spined sea urchin, Diadema antillarum, in
the early 1980s, the dynamics of coral reef ecosystems in the Caribbean have changed …

The sensitivity of long-spined sea urchins (Diadema savignyi) collected from Guam
(Northern Marianas Islands), USA, to nickel and copper in seawater was explored using 48 …

Metallic pollution is of particular concern in coastal cities. In the Asian megacity of Hong
Kong, despite water qualities have improved over the past decade, some local zones are …

The sea urchin embryo-toxicity test is widely used to assess the toxicity of contaminants and
environmental matrices. In standard guideline and literature studies, the classical toxicity …

Inland aquatic and marine systems represent containers for virtually all contaminants, via
direct and indirect contributions (Peijnenburg et al., 1997). Research on the action of heavy …

Echinoderms play a crucial role in the functioning of marine ecosystems and due to their
extensive distribution, rapid response, and the high sensitivity of their planktonic larvae to a …

Abstract Copper oxide nanoparticles (CuO NPs) are widely used in various industrial
applications, ie semiconductor devices, batteries, solar energy converter, gas sensor …
