Di-N-butyl phthalate essay
The MARS study found that male exposure to high levels of a single endocrine disruptor, dibutyl phthalate DBP, can reduce sperm motility in people not treated with DBP. Abstract. Di-n-butyl phthalate DBP is an endocrine disrupting chemical that may affect male reproduction. However, the reproductive effects of low-dose DBP are still not well understood, especially at the molecular level. In the present study, pubertal male Sprague-Dawley rats were orally administered DBP over a wide range. The microbial degradation of di-n-butyl phthalate DBP by a denitrifying bacterium, with nitrate as the only electron acceptor, was investigated. The isolated denitrifying bacteria was degraded. DBP h. A total. nitrate severely inhibited cell growth due to the toxic effect of the accumulated nitrite.1. Introduction. Phthalate esters PAEs have since been widely used as plasticizers because they can increase the ductility and flexibility of various synthetic materials. Cheng et al. 2018. They are commonly used in toys, food packaging, personal care products, wallpaper and many other materials. Du et al. 2020. Currently, 80 of the phthalates are a broad group of compounds that serve as plasticizers to give products flexibility and durability. 1 2 They are ubiquitous in the environment, as millions of tons of plastic are produced worldwide every year. 3 The toxicology and biochemical interaction of phthalates with human physiology has received increasing attention,
