Abstract Human existence and societal growth are both dependent on the availability of clean fresh water. Photocatalysis is a type artificial photosynthesis that uses environmentally friendly, long-lasting materials to address energy environmental issues. There currently considerable demand for low-cost, high-performance wastewater treatment equipment. By changing structure, size, characteristics nanomaterials, use nanotechnology in field water filtration has evolved dramatically. Semiconductor-assisted photocatalysis recently advanced become among most promising techniques fields sustainable generation ecological cleanup. It beneficial, cost-effective, strictly linked zero waste discharge principle used industrial effluent treatment. Owing reduction or removal created unwanted byproducts, green synthesis photoactive nanomaterial more beneficial than chemical approaches. Furthermore, unlike methods, method does not require expensive, dangerous, poisonous ingredients, making it less costly, easy, photocatalyst synthesis. This work focuses distinct greener utilized production new photocatalysts, including metals, metal doped-metal oxides, plasmonic nanostructures, application intelligence machine learning design selection an innovative context challenges. A brief overview applications photocatalysts also presented. Finally, recommendations future research given create photocatalytic systems with greatly improved stability efficiency.

Semiconductor-based photocatalytic reactions are a practical class of advanced oxidation processes (AOPs) to address energy scarcity and environmental pollution. By utilizing solar as clean, abundant, renewable source, this process offers numerous advantages, including high efficiency, eco-friendliness, low cost. In review, we present several methods construct various photocatalyst systems with excellent visible light absorption efficient charge carrier separation ability through the optimization materials design reaction conditions. Then it introduces fundamentals photocatalysis in both clean generation remediation. other parts, introduce approaches enhance activity by applying different strategies, semiconductor structure modification (e.g., morphology regulation, co-catalysts decoration, doping, defect engineering, surface sensitization, heterojunction construction) tuning optimizing conditions (such concentration, initial contaminant pH, temperature, intensity, charge-carrier scavengers). Then, comparative study on performance recently examined photocatalysts applied production remediation will be discussed. To realize these goals, H2 via water splitting, CO2 reduction value-added products, dye, drug photodegradation lessen toxic chemicals, presented. Subsequently, report dual-functional for simultaneous pollutant reactions. brief discussion about industrial economical applications is described. The follows introducing application artificial intelligence machine learning selection an innovative issues. Finally, summary future research directions toward developing significantly improved efficiency stability provided.

Groundwater Quality and Health: Making the Invisible Visible

Environmental Science & Technology, Год журнала: 2023, Номер 57(13), С. 5125 - 5136

Опубликована: Март 6, 2023

Linking groundwater quality to health will make the invisible visible, but there are knowledge gaps understand linkage which requires cross-disciplinary convergent research. The substances in that critical can be classified into five types according sources and characteristics: geogenic substances, biogenic elements, anthropogenic contaminants, emerging pathogens. most intriguing questions related quantitative assessment of human ecological risks exposure via natural or induced artificial discharge: What is list released from discharging groundwater, what pathways receptors' substances? How quantify flux during discharge? procedures we follow assess Answering these fundamental for humans deal with challenges water security quality. This perspective provides recent progresses, gaps, future trends understanding between health.

Pharmaceuticals and Personal Care Products as Emerging Environmental Contaminants: Prevalence, Toxicity, and Remedial Approaches

ACS Chemical Health & Safety, Год журнала: 2023, Номер 30(6), С. 362 - 388

Опубликована: Ноя. 3, 2023

Pharmaceuticals and Personal Care Products (PPCPs) are synthetic compounds widely used as consumer items such cosmetics therapeutic drugs across the globe. The inappropriate disposal of PPCPs in environment has raised serious concerns regarding their potential adverse impacts on human animal health. Hence, present study aims to delve into environmental contamination numerous detrimental biota climate change. Mining data published relevant literature revealed that active ingredients metabolites generally invade ecosystem via multiple sources. Varying concentrations these contaminants reported surface water, groundwater, wastewater treatment plants. majority pose acute chronic toxicity living organisms. They adversely affect structure function algal community along with feeding, mating, metabolic activities, reproductive behavior invertebrates, fishes, higher vertebrates, including humans. occurrence antibiotic resistance bacterial populations a response PPCP is another health concern. In addition, targeting mitochondrial respiratory proteins cytochrome enzymes by might contribute onset physiological ailments. Studies have deciphered connection between methanogenesis, which could potentially impact Several degradation methods been for removal PPCPs. However, none them completely remove from samples. Therefore, developing more advanced eco-friendly approaches warranted better water media. further investigations required risk assessment several not yet investigated.

Groundwater deterioration due to enrichment with contaminants of either geogenic or anthropogenic origin has adversely affected safe water supply for drinking and irrigation, pervasive impacts on human health ecosystem functions. However, the spatiotemporal evolution public effects groundwater quality remain unclarified, posing a grand challenge sustainable global resources. This article provides state-of-the-art review complexity dynamics quality, as well various substances health. In particular, knowledge is growing about key ranging from nutritional elements (e.g., Ca 2+ , Mg ) pollutants heavy metals/metalloids, persistent organic pollutants, emerging contaminants) and, further, pathogenic microorganisms which body can be exposed through multiple patterns use. Proliferating concerns at same time call enhancing science-based governance directives, economic policies, management strategies coordinating quality.

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.
