– Chromium (Cr) has both essential and toxic forms; Hexavalent chromium (Cr(VI)) is highly toxic and carcinogenic.
– Mercury (Hg) is a heavy metal that is highly toxic, particularly in its organic form (methylmercury), affecting the nervous system.
– Copper (Cu) is an essential trace element necessary for many biological processes. While excessive intake can cause toxicity, it is less likely to be classified as *highly toxic* compared to arsenic, mercury, and certain forms of chromium in common environmental exposures, as the body has mechanisms to regulate copper levels and it is required for life.
