“…In general, HHCB is a more frequently used fragrance than AHTN, resulting in higher levels of it in the environment [36,44]. On the other hand, HHCB is more readily biodegradable than AHTN, and AHTN is preferentially absorbed on particles, resulting in variation in the ratio of HHCB to AHTN during transportation in aquatic systems.…”

The Pearl River (China) and its tributaries receive discharges of treated/untreated domestic sewage and industrial wastewater throughout the entire drainage basin. The river provides source water for many local inhabitants, and there is great concern over its pollution status. Fifteen sediment samples were collected from source water areas in the Pearl River Delta, and analyzed for the occurrence and distribution of 2 classes of emerging pollutants, organophosphorus flame retardants (OPs) and synthetic musks. In most sediments, 5 polycyclic musks and 2 nitro musks were detected, and galaxolide (1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta (g)-2-benzopyran [HHCB]) and tonalide (7-acetyl-1,1,3,4,4,6-hexamethyl-1,2,3,4-tetrahydronaphthalene [AHTN]) were the predominant components, with concentrations of 0.030 to 547 and 4.31 to 439 ng/g, respectively. Seven widely used OPs were found in most sediments, at varying total concentrations from 1.79 to 143 ng/g, with tris(2-butoxyethyl) phosphate (TBEOP), tris(2-chloro-isopropyl) phosphate (TCIPP), and triphenyl phosphate (TPHP) being the main components. The results indicated that industrial discharge and domestic sewage played important roles for synthetic musk and OP distribution in sediments in the study area. In general, higher levels of OPs and synthetic musks were found in Guangzhou, Foshan, and Dongguan, suggesting a significant impact from industrial discharges and the dense population of these regions.

“…Trace organic contaminants (TrOCs) include diverse groups of chemicals such as pharmaceuticals and personal care products (PPCPs), pesticides, surfactants and industrial chemicals. Due to their ineffective removal by the conventional wastewater treatment processes, these TrOCs are commonly detected in the aquatic environment including surface water and groundwater, and even seawater [1,2,3]. Most TrOCs are biologically active even at trace concentrations (in the range of few ng/L) and can impose detrimental impacts on aquatic environment as well as on human health [4,5].…”

White-rot fungi (WRF) mediated treatment can offer an environmentally friendly platform for the removal of pharmaceuticals and personal care products (PPCPs) from wastewater. These PPCPs may have adverse impacts on aquatic organisms and even human and thus their removal during wastewater treatment is of significant interest to the water industry. Whole-cell WRF or their extracellular lignin modifying enzymes (LMEs) have been reported to efficiently degrade PPCPs that are persistent to conventional activated sludge process. WRF mediated treatment of PPCPs depends on a number of factors including physicochemical properties of PPCPs (e.g., hydrophobicity and chemical structure) and wastewater matrix (e.g., pH, temperature, and dissolved constituents), type of WRF species and their specific extracellular enzymes. This review critically analyzes the performance of whole-cell WRF and their LMEs for the removal of PPCPs; particularly, it offers insights into PPCP removal mechanisms (e.g., biosorption vs. biodegradation) and degradation pathways as well as the formation of intermediate byproducts.

“…Since AHTN has the same molecular mass than HHCB but with a different chemical structure (Table 1), we performed the enrichment experiment for both from the HHCB sediment slurry incubation. Then, OC was added to this list due to its occurrence in coastal sediments (Combi et al, 2016;Mitchelmore et al, 2019). ECs were added independently at 100 μM final concentration (corresponding to 25, 25, 28, 36 and 24 ppm, respectively) according previous experiments (Vallecillos et al, 2017;Balk and Ford, 1999;König et al, 2016;Sauvêtre et al, 2018).…”

Despite emerging contaminants (ECs) are more and more monitored in environmental matrices, there is still a lack of data in marine ecosystems, especially on their fate and degradation potentials. In this work, for the first time, the degradation potential of synthetic musks (galaxolide and tonalide), UV filters (padimate O and octo-crylene) and a pharmaceutical compound (carbamazepine) was studied in marine sediment samples, under laboratory conditions using sediment slurry incubations under biotic and abiotic conditions. Minimum half life times under biotic conditions were found at 21 days, 129 days and 199 days for padimate O, galaxolide and carbamazepine, respectively. Enrichments conducted under anoxic and oxic conditions demonstrated that de-gradations after one month of incubation either under both biotic and abiotic conditions were limited under anoxic conditions compared to oxic conditions for all the contaminants. Novel aerobic bacteria, able to degrade synthetic musks and UV filters have been isolated. These novel strains were mainly related to the Genus Bacillus. Based on these results, the isolated strains able to degrade such ECs, can have a strong implication in the natural resilience in marine environment, and could be used in remediation processes.
