“…Two alkylphenols, 4- tert -butylphenol (4 t BP) and 4- tert -octylphenol (4 t OP), have been frequently detected in water and sediments of both freshwater and marine environments. − 4 t BP is widely used for synthesizing phenols and polycarbonate resins, , while 4 t OP is used in the production of pesticides, paints, plastics, and detergents . Both 4 t BP and 4 t OP are regarded as an endocrine disruptor − and are difficult to biodegrade in aquatic environments. − Their aquatic toxicity on fish and zooplankton has been previously demonstrated. ,− Whereas limited data of these alkylphenols are available regarding their toxicity towards benthic organisms via sediment contamination. The estimated log K ow and log K oc are 3.31 and 2.76 for 4 t BP , and 4.12 and 3.44 for 4 t OP, respectively.…”

Organic pollutants with high solid–water equilibrium partition coefficients are adsorbed into solid particles and are easily ingested by benthic organisms, potentially causing dietborne toxicity. Whether dietborne toxicity is more important than waterborne toxicity for such chemicals remains to be determined. In this study, we identify the most relevant uptake route for the toxicity of two alkylphenols, 4-tert-butylphenol (4tBP), and 4-tert-octylphenol (4tOP). To achieve this, 6-day toxicity tests under two exposure conditions, namely dietary exposure (clean water + contaminated food) and combined exposure (contaminated water + contaminated food) were conducted on a benthic ostracod, Heterocypris incongruens. The toxicologically important exposure routes were confirmed by the consistency of dietary and aqueous dose–response relationships under different exposure conditions. During the test, frequent renewal of water and food was performed to reduce variability in the exposure conditions. The results showed that, under the equilibrium condition, the dietary exposure route was toxicologically more important than the aqueous route for 4tBP, whereas the waterborne exposure route was more important than the dietary exposure route for 4tOP. This study provides a novel approach to identify the most relevant uptake pathways for chemical toxicity, which better explains the importance of exposure routes in toxicity effects.

“…A higher GSH level in F. solani 8F possibly implicates GSH in NP and 4-t-OP degradation, as well as in strain tolerance to higher AP concentrations. As is known, NP and 4-t-OP induce oxidative stress due to an accumulation of reactive oxygen species in eukaryotic cells [ 42 , 43 ]. Activation of lipid peroxidation is a component of the fast stress response.…”

A total of 11 ascomycete strains destructing technical nonylphenol (NP) and 4-tert-octylphenol (4-t-OP) were isolated from NP-contaminated soddy-podzolic loamy soil (Leningrad Region, Russia). The isolates proved capable of degrading NP and 4-t-OP at a high load (300 mg/L). The most efficient Fusarium solani strain 8F degraded alkylphenols (APs) both in cometabolic conditions and in the absence of additional carbon and energy sources. A decrease in APs was due to biodegradation or biotransformation by the strain and, to a minor extent, absorption by fungal cells. NP and 4-t-OP half-lives were, respectively, 3.5 and 6.4 h in cometabolic conditions and 9 and 19.7 h in the absence of additional carbon and energy sources. Amounts of the lipid peroxidation product malondialdehyde (MDA) and reduced glutathione (GSH) increased during NP and 4-t-OP biodegradation in cometabolic conditions by 1.7 and 2 times, respectively, as compared with a control. A high GSH level in F. solani 8F cells potentially implicated the metabolite in both AP biodegradation and strain resistance to oxidative stress. The study is the first to report on the NP and 4-t-OP degradation by the ascomycete F. solani in cometabolic conditions and in the absence of additional carbon and energy sources. The high AP degradation potential of soil ascomycetes was assumed to provide a basis for new environmentally safe bioremediation technologies for purification of soils and natural and waste waters contaminated with endocrine disruptors.

“…For example, reduced growth of C. demersum versus increased concentrations of the heavy metals nickel and cadmium have been previously reported (Chorom et al, 2012). In previous studies, a decrease in the growth of this plant against high concentrations of non-ionic surfactant 4-tert-octylphenol (OP) has been reported (Chiu & Wu, 2017). Also, reduced growth of aquatic plants Nasturtium officinale (Torbati et al, 2015), Lemna minor L. (Khataee et al, 2012), and aquatic fern Azolla filiculoides Lam.…”

This study evaluated the ability of the submerged aquatic plant Ceratophyllum demersum to remove the Acid Blue 92 (AB92) dye. The effect of some operational parameters such as the reaction time, initial dye concentration, initial plant biomass, and pH, on dye removal efficiency was studied. Based on Taguchi’s results, the optimized conditions for dye removal were time 7 days, dye concentration 20 mg l-1, initial plant biomass 4 g, and initial pH 5. Fourier-transform infrared spectroscopy (FTIR) results confirmed the interaction between dye molecules and plants. Based on the results of this study, C. demersum had a reusability to remove the dye, this fact confirming the mechanism of biodegradation in the dye removal process. Also, the effect of AB92 on the physiological responses of C. demersum was investigated. Minimum relative growth rate, tolerance index, chlorophyll a, chlorophyll b, total chlorophyll, and total carotenoids at a concentration of 20 mg l-1 of AB92 were observed. The concentration of cyanidin glycoside, lipid peroxidation, and antioxidant activity increased in both concentrations of 10 and 20 mg l-1. It can be concluded that both concentrations of AB92 induced antioxidant activity and the risk of oxidative stress for Ceratophyllum.
