“…However, the few studies that were found were insufficient to draw meaningful conclusions. reported to be weakly mutagenic in S. typhimurium (Andrews et al 1978) and weakly genotoxic in the E. coli SOS chromotest (Mersch-Sundermann et al 1992a.…”

“…There is concern about the presence of these compounds in the environment as they have been shown to exhibit toxic, mutagenic and carcinogenic effects (Andrews et al, 1978;Fujikawa et al, 1993;Mersch-Sundermann et al, 1992). PAHs may enter the environment through many routes.…”

Degradation of high molecular weight polycyclic aromatic hydrocarbons by Pseudomonas cepacia

1996

When inoculated at high cell densities, three strains of Pseudomonas cepaciu degraded the polycyclic aromatic hydrocarbons (PAHs) benzo[a]pyrene, dibenz [u,h]anthracene and coronene as sole carbon and energy sources. After 63 days incubation, there was a 20 to 30% decrease in the concentration of benzo [u]pyrene and dibenz [u,h]anthracene and a 65 to 70% decrease in coronene concentration. The three strains were also able to degrade all the PAHs simultaneously in a PAH substrate mixture containing three-, four-, five-and sevenbenzene ring compounds. Furthermore, improved degradation of the five-and seven-ring PAHs was observed when low molecular weight PAHs were present.

“…Secondary photolytic reactions in the atmosphere with organic fractions and oxides of nitrogen and sulfur further increases the PAH concentration (Schoential, 1964). These are of marked environmental concern due to air pollution as several of them are either known to be carcinogens or are suspected carcinogens and muteness (Andrews et al, 1978;Hoffman and Winder, 1968).…”

Air pollution has significant effects on exacerbation of asthma, allergy and other respiratory diseases. Like many other magacities in the world the ambient air quality of Kolkata is also being deteriorated day by day. Automobile exhausts and certain industrial pollutants produce O(3) by photochemical reactions. The particulate matter, particularly less than 10 microm in size, can pass through the natural protective mechanism of human respiratory system and plays an important role in genesis and augmentation of allergic disorders. Sources of air pollution in the area and the unique problem arising out of the emission from the vehicles, industries, etc. have been described. Ambient air quality was monitored along with micrometeorological data and the results are discussed. The status of air pollution in the area has been evaluated and a questionnaire survey was conducted to estimate the allergic symptoms and exposure to assess the respiratory disorders. The data are analysed to evaluate the critical situation arising out of the emission of air pollutants and the impact on human health due to respirable diseases (RDs) to middle class sub-population (activity-wise) in the area are assessed. A strategic air quality management plan has been proposed. For the mitigation of air pollution problems in the city, the different measures to be adopted to maintain the balance between sustainable development and environmental management have been discussed.
