Duckweeds for Phytoremediation of Polluted Water

Plants, Год журнала: 2023, Номер 12(3), С. 589 - 589

Опубликована: Янв. 29, 2023

Tiny aquatic plants from the Lemnaceae family, commonly known as duckweeds, are often regarded detrimental to environment because of their ability quickly populate and cover surfaces bodies water. Due rapid vegetative propagation, duckweeds have one fastest growth rates among flowering can accumulate large amounts biomass in relatively short time periods. high yield valuable ease harvest, be used feedstock for biofuels, animal feed, other applications. Thanks efficient absorption nitrogen- phosphate-containing pollutants, play an important role restorative ecology water reservoirs. Moreover, compared species, duckweed species ecotypes demonstrate exceptionally adaptivity a variety environmental factors; indeed, remove convert many contaminants, such nitrogen, into plant biomass. The global distribution tolerance ammonia, heavy metals, stresses major factors highlighting potential use purifying agricultural, municipal, some industrial wastewater. In summary, powerful tool bioremediation that reduce anthropogenic pollution ecosystems prevent eutrophication simple, inexpensive ecologically friendly way. Here we review using phytoremediation several pollutants: mineral nitrogen phosphorus, various organic chemicals, metals.

Occurrence of contaminants of emerging concern and pesticides and relative risk assessment in Tunisian groundwater

The Science of The Total Environment, Год журнала: 2023, Номер 906, С. 167319 - 167319

Groundwater is an important source for drinking water supply, agricultural irrigation and industrial uses in the Middle East North Africa region. Due to growing need groundwater use, quality studies on presence of contaminants emerging concern (CECs) pesticides have gained attention. The Wadi El Bey one most polluted areas Tunisia. However, very limited data CECs infiltration into aquifers has been described, comparison industrialized countries where contamination comprehensively addressed. To gain early insight potential contamination, wells northeast Tunisia, area with high population density intensive activity were sampled during two seasons analyzed resolution mass spectrometry approaches: target suspect screening. latter was used screening banned pesticides. A selection 116 which 19 are transformation products (TPs) 20 previously prioritized by screened samples. results showed 69 1 TP at concentrations per well, ranging between 43 7384 ng L-1 7.3 80 L-1, respectively. Tunisian do not differ from those countries. WWTPs considered main pollution, classes detected analgesics, antihypertensives artificial sweeteners especially caffeine, salicylic acid ibuprofen found be ubiquitous. Regarding pesticides, triazines herbicides carbamates insecticides pose highest due their ubiquitous presence, leachability them toxicity. environmental risk assessment (ERA) highlighted that ibuprofen, propoxur may environment, consequently, non-target organisms. This study provides occurrence ERA analysis groundwater.

Occurrence, Bioaccumulation, Metabolism and Ecotoxicity of Fluoroquinolones in the Aquatic Environment: A Review

Toxics, Год журнала: 2023, Номер 11(12), С. 966 - 966

Опубликована: Ноя. 29, 2023

In recent years, there has been growing concern about antibiotic contamination in water bodies, particularly the widespread presence of fluoroquinolones (FQs), which pose a serious threat to ecosystems due their extensive use and phenomenon "pseudo-persistence". This article provides comprehensive review literature on FQs summarizing analyzing levels global surface over past three as well bioaccumulation metabolism patterns aquatic organisms, ecological toxicity, influencing factors. The results show that is across surveyed 32 countries, with ciprofloxacin norfloxacin being most heavy contaminants. Furthermore, are generally higher developing developed countries. It observed compound types, species, environmental factors influence bioaccumulation, metabolism, toxicity organisms. tend accumulate more organisms lipid content, experiments have shown exhibit highest bacteria weakest mollusk. summarizes analyzes current research status shortcomings FQs, providing guidance theoretical support for future directions.

A novel and sustainable composite of L@PSAC for superior removal of pharmaceuticals from different water matrices: Production, characterization, and application

Environmental Research, Год журнала: 2024, Номер 251, С. 118565 - 118565

Опубликована: Март 1, 2024

This study endeavors to develop cost-effective environmentally friendly technology for removing harmful residual pharmaceuticals from water and wastewater by utilizing the effective adsorption of pistachio shell (PS) biochar degradation potency laccase immobilized on (L@PSAC). The carbonatization activation shells were optimized regarding temperature, time, NH4NO3/PS ratio. step yielded an optimum PS (PSAC) with highest porosity surface area treated at 700 °C 3 h using ratio 3% wt. immobilization onto PSAC (L@PSAC) was its best level pH 5, 60 U/g, 30 °C. L@PSAC maintained a high enzyme activity over two months. Almost complete removal (>99%) diclofenac, carbamazepine, ciprofloxacin in Milli-Q (MQ) achieved. Adsorption responsible >80% rest facilitated degradation. ≥60% up six treatment cycles underscoring promising application this material treatment. These results indicate that activated carbon derived could potentially be utilized as carrier adsorbent efficiently remove pharmaceutical compounds. enzymatic physical elimination approach has potential used large-scale.

Current scenario of emerging pollutants in farmlands and water reservoirs: Prospects and challenges

Ecotoxicology and Environmental Safety, Год журнала: 2025, Номер 291, С. 117829 - 117829

Опубликована: Фев. 1, 2025

Globally, roughly more than 400 million metric tons of plastics are produced annually. Similarly, the pharmaceuticals business is rising exponentially yearly, 5.8 %. It expected to increase from USD 714 billion 1454 by 2029. Beyond their intended uses, these substances released into environment as contaminants due improper usage and management practices. Therefore, microplastics (MPs) classified emerging pollutants (EPs), existence in agricultural ecosystems adversely affects soil environmental health, ultimately impacting both ecological human well-being. Pharmaceuticals MP-loaded organic amendments (especially manure) a primary cause pollutants. The increasing application treated wastewater or biosolids irrigation water conditioners, mainly when derived untreated sewage sludge, can introduce MPs farmlands, merging within medium. co-occurrence leads prolonged presence gradual bioaccumulation organisms over time, contributing persistent contamination long-lasting effects on ecosystems. Moreover, EPs have potential alter composition biogeochemistry disrupt overall health productivity. Numerous methods been developed address this issue, including electrochemical degradation, advanced oxidation processes, photocatalytic biosurfactants, micro- nano-bubble systems, ultrasonic cavitation, nanotechnology, constructed wetlands, many hybrid approaches. This review explores extent EPs, interactions, strategies EPs-contaminated environments.

Ecotoxicology and Environmental Safety, Год журнала: 2023, Номер 259, С. 115024 - 115024

Опубликована: Май 17, 2023

The occurrence of PPCPs in aquatic environments and their potential adverse effects on organisms have raised worldwide concerns. To address this issue, a study was conducted to analyze 137 selected Korean surface waters, an optimized risk-based prioritization performed. results revealed that 120 were detected, with 98 quantified at concentrations ranging from few ng/L 42,733 for metformin. 95% upper confidence limit (UCL95) the mean value measured environmental concentration (MEC) Metformin about eight times higher than second highest compound, dimethyl phthalate, indicating antidiabetic groups had among therapeutic groups. An then assessed based multiplication two indicators, Frequency Exceedance Extent Predicted No-Effect Concentrations (PNECs), which can be calculated using traditional risk quotient (RQ) approach. found clotrimazole 17.4, high organisms, seven 13 compounds showing RQ values above 1 0.1, respectively. After considering frequency exceedance, still novel (RQf) 99.6% its MECs exceeding PNECs. However, number RQf decreased five, cetirizine flubendazole being excluded. Furthermore, only 10 exhibited 0.1. also observed significant differences between exposure-based methods, five compounds, cetirizine, olmesartan, climbazole, sulfapyridine, imidacloprid, identified both methods. This finding highlights importance multiple methods prioritizing chemicals, as different approaches may yield results.
