The crystals of the new melaminium salt, 2,4,6-triamino-1,3,5-triazin-1-ium hydrogenphthalate, C3H7N6+.C8H5O4-, are built up from single protonated melaminium residues and single dissociated hydrogenphthalate(1-) anions. The protonated melaminium ring is almost planar.

Toxicology Mechanisms and Methods, 2014
Many of the environmental, occupational and industrial chemicals are able to generate reactive oxygen species (ROS) and cause oxidative stress. ROS may lead to genotoxicity, which is suggested to contribute to the pathophysiology of many human diseases, including inflammatory diseases and cancer.

Biodegradation of phthalates and phthalate esters
Proceedings / Indian Academy of Sciences, 1984Several microorganisms utilising terephthalate and diethylphthalate have been isolated from garden soil. Protocatechuate was one of the intermediates in the degradation of terephthalic acid and diethylphthalate. Accumulation of protocatechuate during the growth of these strains has been described.

Phthalates: Toxicology and exposure
International Journal of Hygiene and Environmental Health, 2007Phthalates are used as plasticizers in PVC plastics. As the phthalate plasticizers are not chemically bound to PVC, they can leach, migrate or evaporate into indoor air and atmosphere, foodstuff, other materials, etc. Consumer products containing phthalates can result in human exposure through direct contact and use, indirectly through leaching into ...

Biological impact of phthalates
Toxicology Letters, 2013Esters of phthalic acid are chemical agents used to improve the plasticity of industrial polymers. Their ubiquitous use in multiple commercial products results in extensive exposure to humans and the environment. This study investigated cytotoxicity, endocrine disruption, effects mediated via AhR, lipid peroxidation and effects on expression of enzymes

Biochemistry, 2004
The phthalate dioxygenase system, which catalyzes the dihydroxylation of phthalate to form its cis-dihydrodiol (DHD), has two components: phthalate dioxygenase (PDO), a multimer with one Rieske-type [2Fe-2S] and one Fe(II) center per monomer, and phthalate dioxygenase reductase (PDR), which contains flavin mononucleotide (FMN) and a plant-like ...

Phthalates in the NICU: a survey
Archives of Disease in Childhood - Fetal and Neonatal Edition, 2019Phthalates are chemicals used to enhance the flexibility, solidity and durability of plastics. In neonatal intensive care units (NICU), neonates are exposed to phthalates percutaneously, through drugs, blood transfusions and medical devices (MD) used for ventilation, infusions, nutrition, with daily doses potentially exceeding by far doses considered ...

Phthalate Risks, Phthalate Regulation, and Public Health: A Review
Journal of Toxicology and Environmental Health, Part B, 2009As a result of concerns about the toxicity of phthalates to humans, several expert panels were convened toward the end of the 1990s to evaluate the implications of the scientific evidence for the risks of phthalates to humans of all ages. These panels concluded that the risks were low although they had concerns about specific applications of some ...

Phthalates: metabolism and exposure
International Journal of Andrology, 2007Summary In human metabolism studies we found that after oral application of di(2‐ethylhexyl) phthalate (DEHP), diisononyl phthalate (DiNP) and di(2‐propylheptyl) phthalate (DPHP), at least 74, 44 and 34%, respectively, are excreted via urine. In contrast to the short chain phthalates, their oxidized products, not the simple monoesters, were found to be

Phthalates biodegradation in the environment
Applied Microbiology and Biotechnology, 2008Phthalates are synthesized in massive amounts to produce various plastics and have become widespread in environments following their release as a result of extensive usage and production. This has been of an environmental concern because phthalates are hepatotoxic, teratogenic, and carcinogenic by nature.
