Combined effect of Fe²⁺ ions and the meta-isomer of dihydric phenol on duckweed

The toxic effects of Fe 2+ ions and resorcinol on Lemna minor in their joint presence the aquatic environment were studied. test response bioassay solutions , resorcinol, mixtures was a violation permeability duckweed membranes. This parameter estimated from change electrical conductivity medium which plant placed, exposed to toxicant acute experiment (30 min). It found that addition both an equinormal concentration Fe(II) (0.1n) five-fold deficiency (0.02n) 0.1n solution reduced toxicity resorcinol. Most likely, effect obtained can be achieved by formation new, less compound (probably complex nature). used work, based assessment cell membranes under action toxicants, once again proved promising tool for analyzing combined phenolic compounds metal relation organisms.
