In this study, the degradation of dimethyl phthalate (DMP), taken as model compound for phthalate esters, by the photo-assisted peroxymonosulfate (PMS) process was investigated. The high oxidation potential of hydroxyl and sulfate radicals generated by the activation of PMS under UV-C light irradiation was used to completely oxidize aqueous DMP solutions. Experiments were conducted at varying i...

This study evaluated the phytochemical screening, gas chromatography-mass spectrometry (GC-MS) analysis and antioxidant activity of Curcurbitapepo L. using its leaf sample with standard methods. The used for was procured from Imo State University school farm properly identified. Result screening revealed presence saponins, flavonoids, alkaloids, steroids, phlobactannins, proteins, anthraquinnon...

Tests were conducted to determine the persistence of compounds applied to tents to protect against mosquitoes. Interiors of 2 camping tents were treated by the manufacturer--one with the repellent dimethyl phthalate (DMP) and one with the insecticide permethrin. A third tent was untreated. Tents were set up outdoors and exposed to weathering for one year. Weekly tests were conducted by releasin...

Phthalate acid esters (PAEs) are widely used as raw materials for industries that well known their environmental contamination and toxicological effects “endocrine disruptors”. The determining of PAE was based on analysis dimethyl phthalate (DMP), diethyl (DEP), dipropyl (DPP), dibutyl (DBP), diisobutyl (DiBP), dicyclohexyl (DCHP) di(2-ethylhexyl) (DEHP) in wastewater sediment samples collected...

The research is aimed at solving an urgent problem of microbiology, that studying bacterial degradation processes persistent environmental pollutants, including polycyclic aromatic hydrocarbons (PAHs) and phthalates. study examined the ability bacteria Micrococcaceae family, isolated from technogenically polluted territories Perm Region, to degrade phthalates: esters ortho-phthalic acid, tereph...
