nonylphenol - translation - English-Swedish Dictionary - Glosbe
Under normal conditions, each round of mitosis should result in two identical daughter cells. If you were to observe a cell containing 3 pairs of homologous chromosomes during a normal cell cycle, how many sister chromatids would you expect to find when mitosis begins? Different environmental contaminants disturb the thyroid system at many levels. AlkylPhenols (APs), by-products of microbial degradation of AlkylPhenol Polyethoxylates (APEOs), constitute an important class of Endocrine Disrupting Chemicals (EDCs), the two most often used environmental APs being 4-nonylphenol (4-NP) and 4-tert-octylphenol (4-t-OP). Nonylphenol can be predicted to increase in levels in all the possible matrices, even in human community in the near future as the compounds can moderately biomagnify.

Usually, the nonyl group is attached to the benzene ring at para position, but it can also vary according to the production method. NONYLPHENOL behaves as a very weak organic acid. Incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Consumers can avoid products with NP/NPEs by looking for products with EPA’s Safer Choice Label on the shelves of major retailers. When you see the safer product label on a product it means that EPA scientists have evaluated every ingredient in the product to ensure it meets stringent human health and environmental criteria.

2018-12-05 Nonylphenol is known to be extremely toxic to wildlife, particularly aquatic organisms. There is also concern that it mimics the behaviour of animal hormones, and is an “endocrine disruptor.”. Additionally, exposure to high levels of nonylphenol can also cause irritation of the lungs, digestive system… We demonstrated that 4-nonylphenol was cytotoxic to cells, as revealed by a decrease of the cell number and the decrement of mitochondrial functionality after 24 hr of treatment.
65: This product contains the following ingredients for which the State of California has found to cause cancer, birth defects or other reproductive harm, which would require a warning under the statute: Ethylene oxide; 1,4-Dioxane
The chemical formula of this compound is C 15 H 24 O. Nonylphenol falls under the category of alkylphenols.

Mottier, P. et al. (2014). containing NPE can result in the release of more-toxic nonylphenol (NP) and other degradates to the environment, potentially exposing aquatic life to these compounds. NP is lethal to fish and other aquatic organisms at low concentrations (lower than for the parent compound) in both acute and chronic fish Nonylphenol is a man-made chemical used in a wide variety of agricultural, food, industry and household products.
AlkylPhenols (APs), by-products of microbial degradation of AlkylPhenol Polyethoxylates (APEOs), constitute an important class of Endocrine Disrupting Chemicals (EDCs), the two most often used environmental APs being 4-nonylphenol (4-NP) and 4-tert-octylphenol (4-t-OP). 2013-02-07
Nonylphenol (NP) has been suspected as an endocrine‐disrupting chemical. Japanese polyvinyl chloride (PVC) stretch films contained 0.5–3.3 mg/g of NP and 100–400 mg/g of plasticizers such as diisononyl adipate (DINA), di‐n‐alkyl adipate (DAA), and diacetyllauroyl glycerol (DALG).Migration of NP and plasticizers from PVC stretch films into food simulants (water; 4% acetic acid; 20%
Consequentially, nonylphenol has greater solubility in the matrix with more alkaline character, because in this pH condition, nonylphenol presents greater ionic character, thereby increasing its water affinity.

6 Sep 2013 BPA, NP, and estrogens in drinking water, and these chemicals should be considered when assessing the human risk of their the environment9 as a byproduct of nonylphenol ethoxylates, including BPA, E2, and NP can for biodegradation in these systems does not occur. (Page 25). Application of contaminated sludge to agricultural land needs further assessment(1). While nonylphenol ethoxylate (NPE) surfactants in detergents have seen little chemicals (nonylphenol ethoxylates, or NPEs) which can harm human health and Staff educated these firms about the concerns related to such use and the Biotransformation of nonylphenol ethoxylates (NPEOs) during continuous anaerobic sewage treatment was compared with the than 0.03 µg/L, these compounds in raw water could be and aerobic conditions do not require acclimation of. 17 Mar 2011 is possible that some of these materials could contain NP as a result of the cling film, even though PVC itself does not require an antioxidant 15 Mar 2018 You can find out via the following channels.
