Carcinogenic potential of hydrotreated petroleum aromatic extracts.
Five experimental petroleum extracts were produced from luboil distillates derived from Middle East paraffinic crude by solvent extraction and severe hydrotreatment. The polycyclic aromatic content (PCA) of the extracts was determined by dimethyl sulphoxide extraction and ranged from 3.7-9.2% w/w. The five extracts were evaluated for their potential to induce cutaneous and systemic neoplasia in...
متن کاملBiodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils
Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...
متن کاملCarcinogenic potential of soils contaminated with polycyclic aromatic hydrocarbons (PAHs) in Xiamen metropolis, China.
Xiamen is one of China's most rapidly developing metropolises. The objectives of the present study were: (1) to establish the levels and spatial distribution of polycyclic aromatic hydrocarbons (PAHs) in soil across the Xiamen metropolis, (2) to evaluate the extent to which PAH concentrations were elevated in the high urbanization area (HUA) of the island and how these compared with those in th...
متن کاملPotential Carcinogenic Risks of Aspartame
Aspartame is an intense artificial sweetener with a sweet test approximately 200 times that of sucrose and used as additive in more than 6,000 products. Aspartame was invented by GD-Searle in 1965 and submitted for pre-marketing safety evaluation in early 1980s. The studies conducted by GD-Searle to evaluate the potential carcinogenic risks of aspartame did not show any effect. Because of the g...
متن کاملThe Carcinogenic Activity of Some New Derivatives of Aromatic Hydrocarbons
In 1939 a program of investigation was undertaken in collaboration with Professor Louis F. Fieser and his associates at Harvard University, directed toward a further study of the chemistry of artificial carcinogenesis. The main task was a biological testing for carcinogenicity of a number of new hydrocarbon derivatives synthesized by Dr. Fieser's group. Although the chief purpose of this paper ...
