“…It is also necessary to stress that biodegradation of aged PCP in long-term contaminated soil will be probably not comparable with freshly spiked soil as PCP is known to undergo "ageing" within soil, which is characterized by reduced bioavailability due to sequestration processes (Shaw et al 2000). The experiments described in the current work are based on our previous results obtained at the determination of adsorption, desorption, and retention characteristics of organo-mineral complex (humic acids bound on zeolite) and lignite as potential sorbents used for decontamination of chlorophenols (Dercová et al 2006;Dercová et al 2007). The previous biodegradation experiments showed different PCP degradation potentials of the indigenous (autochthonous) soil bacteria in different types of soil.…”

Biodegradation of pentachlorophenol (PCP) in soil by autochthonous microflora and in soil bioaugmented by the bacterial strain Comamonas testosteroni CCM 7530 was studied. Subsequent addition of lignite, an abundant source of humic acids, has also been investigated as possible sorbent for PCP immobilization. Biodegradation of PCP and number of colony-forming units were determined in the three types of soil, haplic chernozem, haplic fluvisol, and haplic arenosol, freshly spiked with PCP and amended with tested sorbent. The enhancing effect of sorbent addition and bioaugmentation on PCP biodegradation depended mainly on the soil type and the initial PCP concentration. Microbial activity resulted in biotransformation of PCP into certain potentially toxic substances, probably lower chlorinated phenols that are more soluble than PCP, and therefore more toxic toward present biota. Therefore, it was necessary to monitor soil ecotoxicity during biodegradation. Addition of lignite resulted in a significant improvement of PCP biodegradation and led to a considerable decrease of soil toxicity especially in bioaugmented soils. The method could potentially serve as a promising technique in remediation technology for reducing high initial PCP content in contaminated soils.

“…2C -III). In spite of the fact that LIBS is not an absolute method [5] and in the case of investigation of plant tissues it is almost impossible to obtain standard samples that could be used for LIBS calibration [7], the increasing Pb content with higher dose of lead(II) ions was evident on the higher intensity (and area) of the monitored spectral lines. As a control test, we did not observe any Pb signal on the control (untreated) samples.…”

The main aim of this paper is to utilize high performance liquid chromatography with electrochemical detection for determination of thiols content in plants tissues of lettuce treated with lead(II) ions (0, 0.5 and 1 mM). We used two HPLC-ED instruments: HPLC coupled with one channel amperometric detector and HPLC coupled with twelve channel coulometric detector to detect simultaneously twelve thiols. The detection limits of thiols measured by CoulArray detector were about two magnitudes lower in comparison to those measured by Coulochem III detector and were from tens to hundreds pM. Under the optimal conditions, we utilized HPLC-CoulArray detector for analysis of tissues from lettuce plants. In addition, distribution and accumulation of lead ions with high spatial resolution was monitored using laser induced breakdown spectroscopy.

“…In the last decades, several studies were carried out to remove 9 inorganic and/or organic compounds from contaminated soil using 10 physical, biological and/or chemical processes [1][2][3][4][5]. Among the 11 chemical decontamination processes developed, the solubilization 12 of As, Cr, Cu, PCP and DF using alkaline solutions and a bio- 13 surfactant seemed to be very promising in terms of contaminant 14 removal efficiencies and operational costs.…”
