It is used for the manufacturing of antioxidants, lubricating oil, additives, and dish detergents. Nonylphenol can acts as solubilizer and emulsifier. Background. para-Nonylphenol (p-NP) is a metabolite of alkylphenols widely used in the chemical industry and manufacturing.It accumulates in the environment, where it acts with estrogen-like activity.

Nonylphenol can do which of the following

Nonylphenols can come in numerous structures, all of which may be considered alkylphenols. They are used in manufacturing antioxidants, lubricating oil additives, laundry and dish detergents, emulsifiers, and solubilizers. They are used extensively in epoxy formulation in North America but its use has been phased out in Europe. Nonylphenols (NPs) are a family of closely related organic compounds called alkylphenols. They are used in manufacturing antioxidants, lubricating oil additives, laundry and dish detergents, emulsifiers, and solubilizers (Soares et al., 2008). Nonylphenol can do which of the following?

For the possible use of nonylphenol and nonylphenol ethoxylates in veterinary The risk assessment reports indicate that the main use of these nonylphenols is as which is making sure that nonylphenol does not reach water courses and is Brain estrogen production, performed by the enzyme aromatase, can be (EE2), and the estrogenic surfactant 4-nonylphenol (NP), at high (50 mu g/L) and at av MRLKA Palm · Citerat av 21 — tertiary butylphenols, methylphenols, nonylphenol, octylphenol, screening 4-t-OP and 4-NP in one sample each, suggesting that these substances do not toxic chemical, but can also be a result of poor understanding of the toxicity.

demonstrated that 4-tert-octylphenol, technical-nonylphenol, 4-nonylphenol, and bisphenol-A in Anaerobic Membrane BioReactor effluents can be efficiency removed via microalgae [8]. In addition, algae offer advantages of high growth rate, high lipid yield, high environmental tolerance, low competition for arable land and potable water, and no noticeable seasonal limitations on culturing [9] . The acute toxicity of nonylphenol for freshwater animals can vary from 20.7 μg L-1 for the amphipod Hyalella azteca to 774 μg L-1 for snail Physella virgate.

The synthetic organic compound 4-nonylphenol (4-NP) has been shown to have a wide range of adverse effects on the endocrine system of various animals including fish. The present study evaluated the potential effects of 4-NP on vitellogenin (VTG) synthesis, steroid, and thyroid hormone concentrations in both juvenile male and female rainbow trout ( Oncorhynchus mykiss ).
