The biodegradation of nonylphenol (NP) by a newly isolated form of the larva fungal strain Metarhizium robertsii IM 6519 was investigated in this study. This isolate was capable of degrading 4-n-NP, and multiple metabolites were detected. The coexistence of parallel degradation pathways with versatile hydroxylation in different positions of the alkyl chain is a unique feature of this strain. Moreover, several metabolites previously described only in higher eukaryotes were detected in the fungal cultures. The degradation process led to the mineralization of 4-n-NP (with an efficiency of 36%), a great advantage of this strain that results in complete removal of toxic substrate from the environment.

Comparison of adsorption capacity of 4-Nonylphenol on conventional and biodegradable microplastics aged under natural water.

J Contam Hydrol

This study investigated the adsorption of 4-Nonylphenol (4-NP) on aged microplastics (MPs) composed of polyethylene terephthalate (PET) and poly(butylene-adipate-co-terephthalate)/polylactic acid (PBAT/PLA). Morphological analysis revealed wear, wrinkles, and increased surface roughness in both aged MPs, with X-ray diffraction showing slight increases in crystallinity. Infrared spectroscopy showed an increase in the carbonyl index from 2.

The lake riparian zone (LRZ) is a key area of material circulation between terrestrial and aquatic ecosystems. However, the exchange of endocrine disrupting compounds (EDCs) in this area is still unknown. Thus, in this study, the distribution, convection and microbial response of two typical EDCs, bisphenol A (BPA) and nonylphenol (NP), in submerged (SS) and temporarily flooded sediment (FS) of LRZ were investigated by in-situ diffusive gradients in thin films technology.

Aquatic ecosystems face multiple stressors, including thermal fluctuations and chemical pollutants, which can detrimentally impact fish health and ecosystem integrity. This study investigates the individual and combined toxic effects of 4-nonylphenol (4-NP) and thermal stress on juvenile tilapia fish (Oreochromis niloticus). Four groups of fish were exposed to different stressors for 15 days: control, thermal stress (35 °C ± 1 °C), 4-NP exposure (1 mg/L), and a combination of thermal stress and 4-NP.

Exposure to alkylphenols during early pregnancy and the risk of gestational diabetes mellitus: Fetal sex-specific effects.

Alkylphenols (APs) may cause gestational diabetes mellitus (GDM) in pregnant women by impairing glucose metabolism through endocrine disruption. However, the current literature has limited epidemiological evidence on the association between APs exposure and the risk of GDM, especially the lack of evidence on joint exposure. Thus, we evaluated the effect of exposure to APs during early pregnancy on the risk of GDM.

Article Synopsis
  • Surfactants are unique molecules that can reduce surface tension and help break down oils, making them essential in products like detergents and cleaners.
  • Two major types of nonionic surfactants, alkylphenol ethoxylates (APEOs) and alcohol ethoxylates (AEOs), are widely used in many household and industrial applications, but they are also contributing to environmental contamination.
  • Recent studies show that these surfactants can disrupt metabolic health, particularly through affecting thyroid hormone signaling, highlighting the need to further explore their harmful effects in various biological models.
