“…Consequently, a successful biodegradation is strongly related to water content of the soil (24). Since the soil/water ratio affects the mass transfer in the slurry phase bioreactor, therefore, a desired removal rate can be attributed to water content (25). The PHE biodegradation efficiencies at different moisture levels of 50%, 100%, and 200% (slurry) were 23%, 35.5%, and 62.5%, respectively ( Figure 2).…”

Background: Phenanthrene (PHE) is a polycyclic aromatic hydrocarbon (PAH) with crystalline structure of C14H10, which was produced from incomplete combustion of hydrocarbons and fossil fuels and can cause harmful biological effects. Bioremediation using halophilic bacteria is payed attention over chemical methods due to considerable benefits. Methods: In the present study, a halo-tolerant bacterium Bacillus kochii strain AHV-KH14 was isolated from municipal compost, and used for the bioremediation of PHE from the contaminated soil. The effects of operational parameters including soil/water ratio, initial inoculum size, PHE concentration, and salinity on the bioremediation performance were investigated. Results: A biodegradation efficiency of about to 98% was obtained for PHE concentration of 50 mg/ kg and salinity level of 1.5%. By increasing salinity content PHE concentration, PHE biodegradation rate decreased significantly. It was found that the bioremediation efficiency decreased with increasing PHE concentration. It was also revealed that for the unwashed soil sample, cumulative concentrations of different hydrocarbons played an important role in decreasing the efficiency of bioremediation. Conclusion: A natural hydrocarbon-contaminated soil sample with total petroleum hydrocarbon (TPH) concentration of 2350 mg/kg was subjected to bioremediation using the selected conditions of operational parameters, and a biodegradation rate of 17.7% was obtained.

“…43 In this work, the obtained data showed an accumulation of 15.2% of γ-HCH and 24.6% for δ-HCH in sunflower roots. Processes described in the literature without results for sunflower such as dechlorination, metabolizing compounds and generation of metabolites derived from the degradation of the molecule, 44,45 may be related to the results obtained for endosulfan alpha. In this research, the authors studied the bioremediation endosulfan with the use of bacteria and fungi describing its degradation in three final products such as endosulfan lactone, endosulfan dimethylene and endosulfan monoalcohol, suggesting biotransformation routes to generate metabolites and breakdown products.…”

publicado na web em 18/12/2017 Plant model systems are needed to properly conduct basic laboratory studies prior to field applications of phytoremediation. In vitro plant cultures are a useful tool for such research. This study focuses on the removal and/or degradation of 24 persistent organic pollutants under in vitro conditions by Helianthus annuus L (sunflower). The main purpose of exploiting this plant for phytoremediation process is due to its strong adaptability to adverse environments conditions such as resistance to pests, disease, and others. The study of bioremediation effects of all chemical molecules under in vitro conditions showed promising results. Sixteen out of twenty-four compounds evaluated reached up to 87% for remediation. The highest accumulation of pollutants was observed in the roots, showing that these results are consistent with the current literature. Through the study, it was observed effective absorption of POPs with logK ow ranging from 4.50 to 6.91. Sunflower phytoremediation process efficiently detected heptachlor, aldrin, heptachlor epoxide, trans-chlordane, chlordane, dieldrin, DDE, DDT, methoxychlor, mirex and decachlorobiphenyl.

“…In the year 2016, cases of acute poisoning in domestic animals and occupational poisoning in farmers were reported in Italy and Colombia, respectively [27,28]. Several studies demonstrated endosulfan persistence in the environment, such as water and soil, after banning due to its low water solubility [29]. These facts suggest that the banning of endosulfan might not completely eliminate endosulfan poisoning in humans.…”

In-hospital outcomes and delayed neurologic sequelae of seizure-related endosulfan poisoning

Seizure-related endosulfan poisoning had higher progression rates to SE and RSE and higher fatality rates than other drug-induced seizures. However, delayed neurologic sequelae after discharge were not demonstrated. Due to the high progression rates from seizure-related endosulfan poisoning to SE and RSE and the absence of an established treatment for SE-related endosulfan poisoning, physicians should aggressively treat patients who experience a seizure after endosulfan poisoning and who present with decreased GCS score. Lorazepam should be considered a first-line anti-epileptic drug for controlling seizures in patients with endosulfan poisoning.
