Phthalate ester plasticizers in freshwater systems of Venda
The phthalate esters determined were dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP) and di-(2-ethylhexyl) phthalate (DEHP). The internal standard used was n-butyl benzoate. The esters and the internal standard were obtained from SUPELCO and Fluka AG, South Africa.
Di-butyl phthalate (DBP) induces defects during
Di-butyl phthalate (DBP) is a phthalate ester (PAEs) added during the manufacturing of plastics to make them stronger, yet more pliable. DBP is noncovalently bound to plastics resulting in leaching into the environment. Concerning concentrations of DBP have been noted in surface and groundwater, aquatic ecosystems, soil and atmospheric environments globally. Global production of phthalates and
Frontiers | Exposure to Dibutyl Phthalate and Reproductive
Background: Dibutyl phthalate (DBP) was an endocrine disruptor, which may lead to cancer and affects reproductive function when accumulated in the body. But the precise role of DBP in the reproductive system remained controversial.Objective: We employed the meta-analysis to explore the relationship between DBP and reproductive-related outcomes.Methods: We searched relevant literature in PubMed
Dibutyl phthalate contamination accelerates the uptake and
Dibutyl phthalate (DBP) is a typical persistent organic pollutant with a high load in the agricultural soils of vegetable crops. Currently, studies on the toxicity of DBP in vegetable crops are limited. Therefore, in this study, pakchoi (Brassica campestris L.), a typical vegetable crop, was used to evaluate the toxic effects of DBP. Pakchoi

- Is dibutyl phthalate toxic to algae?
- Toxic effects of dibutyl phthalate (DBP) on two fresh algae were originally compared. DBP was more toxic to C. pyrenoidosa than S. obliquus due to cell structure. DBP inhibited photosynthesis by damaging cell membranes and organelles. Increased ROS levels in algae resulted in oxidative stress and lipid peroxidation.
- What is dibutyl phthalate (DBP)?
- [Google Scholar] Articles from Iranian Journal of Pharmaceutical Research : IJPR are provided here courtesy of Brieflands Dibutyl phthalate (DBP) is a phthalic acid ester and is widely used in polymeric products to make them more flexible. DBP is found in almost every plastic material and is believed to be persistent in the environment.
- What are the three most potent phthalates?
- The three most potent phthalates are diethyl phthalate (DEHP), dibutyl phthalate (DBP), and benzylbutyl phthalate (BBP). Not only do they adversely affect health by themselves, but even in small doses they interact with one another in ways we do not understand.
- Does dibutyl phthalate cause breast cancer?
- High-level dibutyl phthalate exposure (≥ 10,000 cumulative mg) was associated with an approximately two-fold increase in the rate of estrogen receptor-positive breast cancer (hazard ratio, 1.9; 95% CI, 1.1 to 3.5), consistent with in vitro evidence for an estrogenic effect of this compound.
- How many phthalates are produced in South Africa?
- South Africa is the only producer of phthalates in Africa and approximately 40 000 metric tons are produced and consumed, mostly in the flexible PVC industry. Phthalates are divided into two distinct groups, with differing applications, properties and toxicological classifications namely ‘low phthalates’ and ‘high phthalates’.
- Do phthalates affect neurodevelopment?
- “Phthalates are widespread endocrine-disrupting chemicals (EDCs) that have been suggested to affect neurodevelopment. However, association between lactational exposure to phthalates and neurodevelopmental effects has rarely been reported in epidemiological studies.
