Le béryllium est un métal très toxique, non radioactif. Il est classé parmi les éléments les plus toxiques comme l'arsenic (As), le cadmium (Cd), le chrome (Cr), le plomb (Pb), le thallium (Tl) et le mercure (Hg). Le béryllium agit comme un poison cancérigène, affectant les membranes cellulaires et se liant à certaines protéines régulatrices dans les cellules. Le béryllium peut rester détectable dans l’urine jusqu'à 10 ans après l’exposition. Il est classé cancérogène de catégorie … WebIonta (ion, iontis, n.; Graece: ἰόν, ἰόντος 'iens') in chemia sunt atomi vel moleculae electrice oneratae, propter augentem, aut diminuentem electronum suorum dotationem, quae in principio neutra est.
