Hidrocarbonetos aromáticos policíclicos (PAHs)

Applications Dibenzothiophene is commonly used in microbial studies as a sole, organic sulfur and carbon source for growth. Research concerning the biodegradation of dibenzothiophene by different types of bacteria is a currently being carried out, as these bacteria have the ability to breakdown other harmful polycyclic hydrocarbons (PAH) as well. This may prove to be a very practical method in removing PAH’s from soils, sludge and crude oils. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Bastiaens, L., et al.: Appl. Environ. Microb., 66, 1834 (2000); Gunam, I., et al.: J. Microbiol. Biotechn., 23, 473 (2013); Omori, T., et al.: Appl. Environ. Microb., 58, 911 (1992)

Applications 1-Methylchrysene is one of the methylated chrysenes (MeChry), as an aryl hydrocarbon receptor (AhR) agonist. Methylated chrysenes (MeChry) are important cigarette smoke constituents and 5-MeChry has been listed as possibly carcinogenic to humans. 1-Methylchrysene is a possible carcinogenic agent. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Amin, S., et al.: Cancer Res., 45, 6406 (1985), Blaha, L., et al.: Toxicol.

Applications 1,2-Dichloronaphthalene is an organic pollutant found in wastewater. References Ryu, J., et. al.: Environ. Sci. Technol., 47, 2394 (2013)

Applications Benzo[k]fluoranthene is used as an optical sensor for nitro-aromatic compounds due to fluorescence quenching of the molecule. It is also a carcinogen and mutagen. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Patra, D. et al.: Sens. Actua. B. Chem., 80, 278 (2001); Wei-Dong, W. et al.: J. Chrom. A., 1173, 27 (2007);

Applications 1-Methyldibenzothiophene, is an alkyldibenzothiophene present in crude oil. Research concerning the biodegradation of Dibenzothiophene by different types of bacteria is a currently being carried out, as these bacteria have the ability to breakdown other harmful PAH’s as well. This may be used in removing spilled oil from marine and terrestrial environments. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Boberg, F., et al.: Erdoel & Kohle, Erdgas, Petrochemie, 47, 187 (1994); Tanaka, Y., et al.: Applied Microbiology and Biotech., 59 (2), 325 (2002); Prince, R., Spill Sci. Tech. Bulletin, 8 (2), 145 (2003);

Stability Hygroscopic Applications 5-Acenaphthenamine is an impurity of Acenaphthene (D448330), which is a polycyclic aromatic hydrocarbon as carcinogenic agent. References Hansen, B., et al.: Environ. Toxicol. Chem., 18, 772 (1999); Czub, G., et al.: Environ. Sci. Technol., 38, 2406 (2004)

Applications (Z)-Tetrachlorvinphos is used in sensitive immunoassay for detection of organophosphorus pesticides. Also, used in exposure characterization of varied major insecticides including neonicotinoids, organophosphates and pyrethroids in urine of young children. Useful in cannabis testing kits as a component of pesticide mixes (P698240).
