Phytoremediation of metals in oil sands process affected water by native wetland species

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 282, P. 116732 - 116732

Published: July 16, 2024

Process affected water and other industrial wastewaters are a major environmental concern. During oil sands mining, large amounts of process (OSPW) generated stored in ponds until reclaimed ready for surface discharge. While much research has focused on organics waters, trace metals at high concentrations may also pose risks. Phytoremediation is cost effective sustainable approach that employs plants to extract reduce contaminants water. The was undertaken mesocosm scale constructed wetlands with exposed OSPW 60 days. objective screen seven native emergent wetland species their ability tolerate metal (arsenic, cadmium, copper, chromium, nickel, selenium, zinc), then evaluate the best performing phytoremediation. All plant species, except Glyceria grandis, tolerated grew OSPW. Carex aquatilis (water sedge), Juncus balticus (baltic rush), Typha latifolia (cattail) had highest survival growth, removal efficiencies arsenic (81-87 %), chromium (78-86 cadmium (74-84 relative metals; greater than 91 % dissolved portions were removed. efficient accumulators all metals, as demonstrated by root shoot bioaccumulation factors; accumulation accumulation. Translocation factor values one (chromium, zinc) (cadmium, cobalt, nickel). results demonstrate potential suitability these phytoremediation number concern could provide an environmentally sound remediation wastewaters.

Aquatic Macrophytes in the Remediation of Atrazine in Water: A Study on Herbicide Tolerance and Degradation Using Eichhornia crassipes, Pistia stratiotes, and Salvinia minima

ACS Omega, Journal Year: 2025, Volume and Issue: unknown

Published: March 15, 2025

Aquatic macrophytes can be used for herbicide remediation provided they exhibit tolerance to the contaminants. This research assessed potential of Salvinia minima, Echhornia crassipes, and Pistia stratiotes, some common aquatic native Brazil, their atrazine, an commonly detected in waterbodies. Plants were cultivated under controlled conditions with five atrazine concentrations (0, 2, 20, 200, 1000 μg L-1) 15 days. S. minima E. crassipes tolerated equal or less than 20 L-1 died at 200 L-1, indicating herbicide's toxicity its selectivity against sensitive species. P. stratiotes concentration up had growth reduced L-1. All species demonstrated ability reduce water lower, being most efficient, reducing by 43% 22% 2 respectively. Atrazine levels within Brazilian (2 CONAMA 2005) European (0.1 Directive 2013/33) regulatory limits do not selectively affect these Thus, show use arazine phytoremediation programs.

Tailor-made bioremediation regime for the specific recalcitrance posed by crude oil leachate

Bioremediation Journal, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 17

Published: March 24, 2025

The present study addresses the critical problem of remediation crude oil leachate, which is generated through leaching highly recalcitrant and solubilized fractions from petroleum hydrocarbon-contaminated sites presents a significant environmental hazard. leachate used in this showed BOD/COD ratio 0.14, indicating high dominance fraction. Eight bacterial strains were selected based on their ability to solubilize degrade leachate. isolates biosurfactant production 0.04–0.73% facilitated solubilization, biodegradation 43.95–87.91%. Bacillus licheniformis highest degradation as well among all. consortium all 8 was then optimize improve performance. Maximum 65.19% obtained at pH 7, 30 °C 1% inoculum concentration.

Pertanika journal of science & technology, Journal Year: 2025, Volume and Issue: 33(S3)

Published: April 23, 2025

This study explores the use of Scirpus grossus for phytoremediation ex-mining lake water, offering a potential low-cost alternative to conventional wastewater treatment. The focus is on removing contaminants such as total iron, nitrate, sulfate, phosphorus, electrical conductivity, chemical oxygen demand, turbidity, and pH. Over 28 days, water was treated with S. assess contaminant removal, results analyzed using mathematical model in Microsoft Excel. simulated exponential reductions pollutants increases pH, absorption coefficients calculated each parameter. found that effectively reduced contaminants, most significant removal iron at 95.45%. pH increased from 2.61 (acidic) 6.29 (neutral), improving its suitability aquatic life. predicted rates closely matched observed data, suggesting reliable forecasting outcomes. Overall, confirms highly effective species cleaning sustainable cost-effective solution industrial findings encourage further research into scalability, long-term effectiveness, integration this technique other management strategies.
