“…Hyalella azteca was used as a toxicity test species for the evaluation of chemical toxicity from sediments and sludges. The US Environmental Protection Agency [ 15 , 16 ] recommended the amphipod H. azteca as a 10-day survival/lethality toxicity test in the standard sediment toxicity test protocol. The present study investigated four compounds (NP, TCS, BP-3, and CAF) from activated WWTP sludge and dewatered sludge samples that were further treated with pressure-assisted ozonation under different conditions.…”

The aim of this study was to understand the distribution of the personal care products nonylphenol (NP), triclosan (TCS), benzophenone-3 (BP-3), and caffeine in the sludges from three wastewater treatment plants (WWTP-A, -B, and -C) in southern Taiwan. The four compounds were analyzed from activated sludge and dewatered sludge samples, and then the samples were treated with pressure-assisted ozonation under different conditions and removal efficiencies. All four target compounds were detected, especially NP, which was detected in the highest concentrations in the activated sludges of WWTP-A and dewatered sludges of WWTP-C at 17.19 ± 4.10 and 2.41 ± 1.93 µg/g, respectively. TCS was dominant in dewatered sludges from WWTP-B, and the highest detected concentration was 13.29 ± 6.36 µg/g. Removals of 70% and 90% were attained under 150 psi at 40 cycles for NP and TCS, respectively, with 5 min of ozonation reaction time, a solid/water ratio of 1:20, and 2% ozone concentration. Ecological risk quotients (RQs) were calculated by the ratios of the 10-day Hyalella azteca (freshwater amphipod) LC50 to the environmental concentrations of the target compounds. High RQs were found to be >10 for NP, TCS, and BP-3 in untreated sludges, resulting in significant ecological risks to aquatic organisms when the sludges are arbitrarily disposed. However, the toxic effects on Hyalella azteca were not significantly different among ozone sludge treatments. The reason for this may be related to the formation of toxic oxidation by-products and incomplete mineralization of organic compounds. This could also be true for unknown intermediates. The relatively high detection frequencies of these emerging compounds in WWTP sludges requires further applications and treatments.

“…The continuous use of household and personal care products (HPCPs) produces an immense amount of chemicals, such as parabens, bisphenols, UV lters, and alkylphenol ethoxylates, which are of great concern due to their well-known endocrine-disrupting properties (Klančič et al, 2022). These chemicals easily enter the environment through man-made activities, thus contaminating the biota, including soil, water, plants and animals.…”

The continuous use of household and personal care products (HPCPs) produces an immense amount of chemicals, such as parabens, bisphenols, UV filters, and alkylphenol ethoxylates, which are of great concern due to their well-known endocrine-disrupting properties. These chemicals easily enter the environment through man-made activities, thus contaminating the biota, including soil, water, plants and animals. Thus, on top of the direct exposure on account of their presence in HPCPs, humans are also susceptible to secondary indirect exposure attributed to the ubiquitous environmental contamination. The aim of this review is therefore to examine the sources and occurrence of these noteworthy contaminants (i.e., parabens, bisphenols, UV filters, alkylphenol ethoxylates), to summarize the available research on their environmental presence and to highlight the potential exposure pathways.
