Question

Chlorinated and non chlorinated organic pollutant degradation

Answer 1

Heya!!

The resuspension of large volumes of sediments that are contaminated with chlorinated pollutants continues to threaten environmental quality and human health. Whereas kinetic models are more accurate for estimating the environmental impact of these events, their widespread use is substantially hampered by the need for costly, time-consuming, site-specific kinetics experiments.

Thanks!

Answer 2

Explanation:

${ \huge{ \texttt{ \fcolorbox{red}{black}{Aɳʂɯҽr}}}}$

Several strains that utilize aromatic solvents were isolated and tested for their ability to degrade chlorinated and non-chlorinated aromatic hydrocarbons. The effect of inoculation with pure bacterial cultures on the degradation of benzene, toluene, o-, m- and p-xylene, chlorobenzene, o-dichlorobenzene and 1,3,5-trichlorobenzene in soil slurries was studied. The compounds for which organisms were added were rapidly degraded. Without inoculation, however, degradation of benzene, toluene, m- and p-xylene and chlorobenzene was slow, while o-xylene and o-dichlorobenzene were only slightly degraded. The results showed that degradation was due to growth of the inoculated ceils using the aromatic compounds as sources of carbon and energy. Addition of activated sludge did not stimulate degradation. The degradation rate of aromatic solvents by the added bacteria in soil slurries was similar or higher than that observed in liquid cultures of the same organisms.
