Evaluation of soil washing process with carboxymethyl-β-cyclodextrin and carboxymethyl chitosan for recovery of PAHs/heavy metals/fluorine from metallurgic plant...
(Elsevier, 2014-08-01)Abstract Polycyclic aromatic hydrocarbons (PAHs)/heavy metals/fluorine (F) mixed- contaminated sites caused by abandoned metallurgic plants are receiving wide attention. To address the associated environmental problems, ... -
Evaluation of enhanced soil washing process and phytoremediation with maize oil, carboxymethyl-β-cyclodextrin, and vetiver grass for the recovery of organochlorin...
(Academic Press, 2014-08-01)Abstract An innovative ex situ soil washing technology was developed in this study to remediate organochlorine pesticides (OCPs) and heavy metals in a mixed contaminated site. Elevated temperature (60 C) combined with ... -
Response surface methodology to understand the anaerobic biodegradation of organochlorine pesticides (OCPs) in contaminated soil—significance of nitrate conce...
(2014-09-01)Abstract Purpose Problems associated with Organochlorine pesticide (OCP)-contaminated soils have received wide attention. To understand the anaerobic biodegradation process constraints, innovative mathematical analysis ... -
Does powder and granular activated carbon perform equally in immobilizing chlorobenzenes in soil?
(Royal Society of Chemistry, 2015)The objective of this study is to compare the efficacies of powder activated carbon (PAC) and granular activated carbon (GAC) as amendments for the immobilization of volatile compounds in soil. Soil artificially-spiked ... -
Enhanced soil washing process for the remediation of PBDEs/Pb/Cd-contaminated electronic waste site with carboxymethyl chitosan in a sunflower oil–water solven...
(2015-02-01)Abstract An innovative ex situ soil washing technology was developed to remediate polybrominated diphenyl ethers (PBDEs) and heavy metals in an electronic waste site. Elevated temperature (50° C) in combination with ... -
Effect of anthropogenic activities on the water quality of Amala and Nyangores tributaries of River Mara in Kenya
(2015-10-30)Abstract Mau Forest in the upper reaches of the Mara River basin has recently undergone increased forest destruction followed by human settlement and agricultural activities. These anthropogenic activities may be ... -
The interactive biotic and abiotic processes of DDT transformation under dissimilatory iron-reducing conditions
(Pergamon, 2015-11-30)Abstract The objective of the study was to elucidate the biotic and abiotic processes under dissimilatory iron reducing conditions involved in reductive dechlorination and iron reduction. DDT transformation was ... -
Positive relationship detected between soil bioaccessible organic pollutants and antibiotic resistance genes at dairy farms in Nanjing, Eastern China
(Elsevier, 2015-11-30)Abstract Co-contaminated soils by organic pollutants (OPs), antibiotics and antibiotic resistance genes (ARGs) have been becoming an emerging problem. However, it is unclear if an interaction exists between mixed ... -
Impact of bioaccessible pyrene on the abundance of antibiotic resistance genes during Sphingobium sp.-and sophorolipid-enhanced bioremediation in soil
(Elsevier, 2015-12-30)Abstract Soils are exposed to various types of chemical contaminants due to anthropogenic activities; however, research on persistent organic pollutants and the existence of antibiotic resistance genes (ARGs) is limited. ... -
Feasibility of an enhanced washing process to extract PBDEs/heavy metals/antibiotics from antibiotic resistance gene-affected soil with aqueous DNA followed by mi...
(2016-03-01)Abstract Purpose Remediation of polybrominated diphenyl ethers (PBDEs)/heavy metals/antibiotics mixed contaminated soil with high abundance of antibiotic resistance genes (ARGs) has being greatly challenging. Materials ... -
Fate processes of chlorobenzenes in soil and potential remediation strategies: A review
(Elsevie, 2017-06-30)Abstract Chlorobenzenes (CBs) are a group of organic pollutants that pose a high environmental risk due to their toxicity, persistence and possible transfer in the food chain. Available data in literature show that CBs ... -
Function of Nitrate Ion and Tea Saponin Application Rates in Anerobic PAH Dissipation in Paddy Soil
(2016-06-01)Abstract In the present study, KNO 3 and tea saponin (TS) were applied to investigate systematically the potential impact of their concentrations on dissipation of anerobic polycyclic aromatic hydrocarbons (PAH) in ... -
The mechanism of 2-chlorobiphenyl oxidative degradation by nanoscale zero-valent iron in the presence of dissolved oxygen
(Springer Berlin Heidelberg, 2017-11-08)It has recently been demonstrated that the addition of nanoscale zero-valent iron (nZVI) to oxygen-containing water or soil aquifers results in the oxidation of organic compounds. However, there has been little insight ... -
Antimicrobial activities of crude leaf extract of Solanum Nigrumon Fusarium Oxysporum and Pseudomonas Syringae cultures in Maseno (Kenya)
(Journal of Asian Scientific Research, 2017)Solanum nigrum (black nightshade) is a common short lived perennial plant found in the Kenyan highlands and worldwide in distribution. It is a small highly branched plant that rarely adopt a habit of more than a foot in ...
