“…Alkylphenol ethoxylates (APEOs) are primarily incorporated into herbicides, pesticides, lubricating oils, and surfactants, and can biodegrade to nonylphenols (NPs), including 4NP. , Similar to other compounds in this contaminant class that are released to the environment though sewage treatment plants and industrial runoffs, sources of 4NP in seawater are derived primarily from the degradation of commercial and industrial products and sewage. High concentrations of this contaminant have been reported in toilet paper, especially those products high in recycled-paper content. , According to assessments by Diehl et al, Morro Bay (California, USA) had the highest 4NP levels measured in septic sludge (3750 mg/kg dry weight), followed by Canada at 4.6–1230 mg/kg dry weight. Killer whale contaminant concentrations in this study (751.78 ± 422.32 ng/g lw) were lower compared to those in organisms of Morro Bay, where levels ranged from 14000 ± 5600 ng/g lw in harbor porpoise (Phocoena phocoena) liver and 138000 ± 55000 ng/g lw in sea otter (Enhydra lutris) liver samples …”

Killer whales (Orcinus orca) have been deemed one of the most contaminated cetacean species in the world. However, concentrations and potential health implications of selected ‘contaminants of emerging concern’ (CECs) and new persistent organic pollutants (POPs) in endangered Southern Resident and threatened Bigg’s (Transient) killer whales in the Northeastern Pacific (NEP) have not yet been documented. Here, we quantify CECs [alkylphenols (APs), triclosan, methyl triclosan, and per- and polyfluoroalkyl substances (PFAS)] and new POPs [hexabromocyclododecane (HBCCD), PFOS, PFOA, and PFHxS] in skeletal muscle and liver samples of these sentinel species and investigate in utero transfer of these contaminants. Samples were collected from necropsied individuals from 2006 to 2018 and analyzed by LC–MS/MS or HRBC/HRMS. AP and PFAS contaminants were the most prevalent compounds; 4-nonylphenol (4NP) was the predominant AP (median 40.84 ng/g ww), and interestingly, 7:3-fluorotelomer carboxylic acid (7:3 FTCA) was the primary PFAS (median 66.35 ng/g ww). Maternal transfer ratios indicated 4NP as the most transferred contaminant from the dam to the fetus, with maternal transfer rates as high as 95.1%. Although too few killer whales have been screened for CECs and new POPs to infer the magnitude of contamination impact, these results raise concerns regarding pathological implications and potential impacts on fetal development and production of a viable neonate. This study outlines CEC and new POP concentrations in killer whales of the NEP and provides scientifically derived evidence to support and inform regulation to mitigate pollutant sources and contamination of Southern Resident killer whale critical habitat and other marine ecosystems.

“…It has been estimated that around 700 annual tons of BPA, only coming from the manufacturing of thermal paper, will find its way to paper recycling sites in Europe each year (EU, 2010). Gehring et al (2004) showed that toilet paper produced from recycled paper contained BPA in concentrations in the range 3.2e46.1 mg g À1 , levels that could lead to significant emissions of BPA to wastewaters. Furthermore, Pivnenko et al (2015) measured BPA in concentrations ranging 0.31e8300 mg g À1 in all the analyzed waste paper samples from Danish households.…”

“…Compared with data reported in the literature, toilet paper concentrations in the present study are on the same order of magnitude. Mean BPA concentrations were reported to be 28 550 µg kg −1 in the EU (Huntsman, 2017), 7300 µg kg −1 in Denmark (Vinggaard et al, 2000), 31 600 (Gehring et al, 2005) and 10 200 µg kg −1 in Germany, 34 500 µg kg −1 in Austria, and less than 0.1 µg kg −1 in China (Gehring et al, 2009). In compost bags, two of the three products with unknown recycled paper content did not contain BPA in measurable amounts, whereas the two products made with recycled paper contained BPA at levels of 5643 and 7984 µg kg −1 , respectively.…”

Bisphenol A (BPA) enters the environment through various industrial and consumer‐related pathways. Industrial sources include BPA manufacturing and secondary industrial uses such as the manufacturing of polymers and other substances based on or containing BPA. However, secondary sources and emissions to the environment, such as those related to the consumer use of articles containing BPA, may be more important than industrial emissions. Although readily biodegradable, BPA is widely distributed in various environmental compartments and living organisms. It is still not well understood which specific sources and pathways are responsible for releasing BPA into the environment. Therefore, we developed FlowEQ, a coupled flow network and fugacity‐based fate and transport model for the assessment of BPA in surface water. The work is divided into two parts. In Part I, inputs needed to support the modeling and model validation were collected. Bisphenol A was measured at 23 wastewater treatment plants (WWTPs) and 21 landfills in Germany. In addition, the BPA content of 132 consumer articles from 27 article classes was analyzed. Bisphenol A concentrations in WWTPs ranged from 0.33 to 910 µg L−1 in influents and from less than 0.01 to 0.65 µg L−1 in effluents, resulting in removal efficiencies of 13%–100%. Average BPA concentrations in landfill leachate ranged from less than 0.01 to approximately 1400 µg L−1. Bisphenol A concentrations measured in consumer articles varied significantly by type, ranging from less than 0.5 µg kg−1 in printing inks up to 1 691 700 µg kg−1 in articles made from recycled polyvinyl chloride (PVC). These concentrations were combined with information on use, leaching, and contact with water to develop estimates of loadings. Together with the results of the FlowEQ modeling presented in Part II, this assessment improves our understanding of the sources and emission pathways of BPA in surface water. The model considers various sources of BPA and can estimate future surface water concentrations of BPA based on changes in use. Integr Environ Assess Manag 2023;00:1–15. © 2023 The Authors.
