| Environmental risk assessment (ERA) of terrestrial environments polluted by heavy metals in Peru requires standardized biological organisms, the use of which is simple, practical, sensitive and repeatable, such as seeds of higher plants used in eco-toxicological bioassays. The aim of this research was to evaluate the phytotoxic effects of Cr6+, Hg2+ and Pb2+ as potassium dichromate (K2Cr(2)0(7)), mercury chloride (Cl2Hg) and lead acetate ((CH3C00)2Pb), respectively, on growing roots of four species of higher terrestrial plants: onions (Allium cepa L., Liliaceae), red beets (Beta vulgaris L., Chenopodiaceae), rice (Oriza sativa L., Poaceae) and radishes (Raphanus sativus L., Brassicaceae) at 192 h (8 days) exposure. Bioassays of static sub-lethal toxicity... |
