Removal of mercury from water by phytoremediation process with Salvinia natans(L.) All.

Abstract

Mercury contamination from human activities is a severe environmental problem. The low cost of rhizofiltration of heavy metal-contaminated environments is causing an increasing interest in these technologies. The present study demonstrates the effectiveness of mercury removal from water by phytoremediation using S. natans. Plants cultured and collected from the environment were used. The study used Hoagland’s liquid medium contaminated with mercury: 0.15, 0.20, and 0.30. The bioconcentration factor obtained was 275–780. The relative growth rate was up to 0.12 g/gd and was much better for cultured plants than those collected from the environment. The removal rate of toxic metal was up to 94%. Total protein increased for cultures plants by up to 84%, while it decreased by up to 30% for those taken from the environment. Total chlorophyll for cultured plants decreased by up to 54%, which could be due to the toxic effect of the metal.

Physiological Responses and Accumulation of the Emerging Contaminant Ivermectin Using Salvinia Minima

“…Total oating leaf number (frond), submerged leaf (root) length (Jampeetong and Brix 2019), and fresh weight (FW) were measured. After visual assessment, leaves showing chlorosis or necrosis effects were counted (Sitarska et al 2023). Morphological parameters were individually evaluated, and data were expressed as the difference between nal and initial time of each system.…”
