“…It is used to enhance the foaming texture in personal care products such as shampoo, shower gel, soaps and also minimize the adverse effects of chemicals especially sodium lauryl sulfate. 1,4-Dioxane is produced during ethoxylation steps in the manufacturing process of other cosmeceutical constituents such as polyethylene glycol, polyoxyethylene, and polyethylene, hence that is why it is not listed as a cosmeceutical component [80].…”

Cosmetic products are used in large quantities across the world. An increasing number of chemical compounds are being added to the formulation of cosmetic products as additives, fragrances, preservatives, stabilizers, surfactants, dye and shine to potentiate their quality, property and shelf life. Owing to their widespread use, active residues of cosmetic products are continuously introduced into the environment in several ways. Many of these chemicals are bioactive and are characterized by potential bioaccumulation ability and environmental persistence, thus exerting a major risk to humans and the health of ecosystems. Hence, the indiscriminate consumption of cosmetics may present a looming issue with significant adverse impacts on public health. This review intends to spotlight a current overview of toxic ingredients used in formulating cosmetics such as parabens, triclosan, benzalkonium chloride, 1,4-dioxane, plastic microbeads, formaldehyde, diazolidinyl urea, imidazolidinyl urea, sunscreen elements (organic and inorganic UV filters) and trace metals. Specific focus is given to illustrate the biological risks of these substances on human health and aquatic system in terms of genotoxicity, cytotoxicity, neurotoxicity mutagenicity, and estrogenicity. In addition to conclusive remarks, future directions are also suggested.

“…1,4-dioxane (C 4 H 8 O 2 ), a colorless and flammable heterocyclic ether compound, has appeared as an emerging surface water and groundwater contaminant [1][2][3]. The International Agency for Research on Cancer (IARC) and the U.S. Environmental Protection Agency (USEPA) have classified 1,4-dioxane as a Group 2B and B2 agent, respectively, which implies that it has a high potential for causing cancer in humans [4][5][6]. This xenobiotic compound has also been listed as a priority pollutant by USEPA [2,6] and as a superfund priority substance by the Agency for Toxic Substances and Disease Registry (ATSDR) due to its probable toxic effects, high chemical stability, persistence in the natural environment, and potency to contaminate drinking water [7].…”

“…Due to its unique physicochemical properties like extreme hydrophilicity (Log K ow : −0.27), low hydrolyzability, less volatility (Henry's law constant: 4.80 × 10 −6 atm-m 3 /mol at 25 • C), low absorbability to solids (Log K oc : 1.23), and less biodegradability (<5% in 60 days under aerobic condition in water) [2,5,13,14], most conventional physicochemical and biological treatment technologies (e.g., air stripping, thermal desorption, activated carbon adsorption, membrane filtration, chemical coagulation, and activated sludge treatment) are found to be ineffective to remove 1,4-dioxane from the contaminated water or wastewater [3,6,8,13]. As a result, industrial discharge of 1,4-dioxane contaminated wastewater, even after treatment using conventional physicochemical and biological technologies, can contaminate the surface water and groundwater with 1,4-dioxane [9].…”

Enrichment and Analysis of Stable 1,4-dioxane-Degrading Microbial Consortia Consisting of Novel Dioxane-Degraders

Biodegradation of 1,4-dioxane, a water contaminant of emerging concern, has drawn substantial attention over the last two decades. A number of dioxane-degraders have been identified, though many of them are unable to metabolically utilize 1,4-dioxane. Moreover, it is considered more preferable to use microbial consortia rather than the pure strains, especially in conventional bioreactors for industrial wastewater treatment. In the present study, a stable 1,4-dioxane-degrading microbial consortium was enriched, namely 112, from industrial wastewater by nitrate mineral salt medium (NMSM). The consortium 112 is capable of utilizing 1,4-dioxane as a sole carbon and energy source, and can completely degrade 1,4-dioxane up to 100 mg/L. From the consortium 112, two 1,4-dioxane-degrading bacterial strains were isolated and identified, in which the Variovorax sp. TS13 was found to be a novel 1,4-dioxane-degrader that can utilize 100 mg/L of 1,4-dioxane. The efficacy of the consortium 112 was increased significantly when we cultured the consortium with mineral salt medium (MSM). The new consortium, N112, could utilize 1,4-dioxane at a rate of 1.67 mg/L·h. The results of the ribosomal RNA intergenic spacer analysis (RISA) depicted that changes in the microbial community structure of consortium 112 was the reason behind the improved degradation efficiency of consortium N112, which was exhibited as a stable and effective microbial consortium with a high potential for bioremediation of the dioxane-impacted sites and contaminated industrial wastewater.

Modern‐day society requires advanced technologies based on renewable and sustainable energy resources to face the challenges regarding environmental remediation. Solar‐inspired photocatalytic applications for water purification, hydrogen and oxygen evolution, carbon dioxide reduction, nitrogen fixation, and removal of bacterial species seem to be unique solutions based on green and efficient technologies. Considering the unique electronic features and larger surface area, 2D photocatalysts have been broadly explored for the above‐mentioned applications in the past few years. However, their photocatalytic potential has not been optimized yet to the adequate level of practical and commercial applications. Among many strategies available, surface and interface engineering and the hybridization of different materials have revealed pronounced potential to boost the photocatalytic potential of 2D materials. This feature review recapitulates recent advancements in engineered materials that are 2D for various photocatalysis applications for environmental remediation. Various surface and interface engineering technologies are briefly discussed, like anion–cation vacancies, pits, distortions, associated vacancies, etc., along with rules and parameters. In addition, several hybridization approaches, like 0D/2D, 1D/2D, 2D/2D, and 3D/2D hybridization, etc., are also deeply investigated. Lastly, the application of these engineered 2D materials for various photocatalytic applications, challenges, and future perspectives is extensively explored.
