Chlorophenols are widely used in various industries, including as preservatives in wood manufacturing, in paper industry, in chemical synthesis, and in biodegradation of herbicide and pesticide [1]. These applications lead to considerable level of contamination in wastewater and ground water [2]. Chlorophenols are highly toxic, poorly biodegradable, and present serious health concerns to human ...

Chlorophenols (CPs) have been suspected to disrupt the endocrine system and thus affect human and wildlife reproduction but less is known about the underlying mechanism. In this study, we investigated the effects of pentachlorophenol (PCP) and 2,4,6-trichlorophenol (TCP) on human adrenocortical carcinoma cell line (H295R). The H295R cells were exposed to environmentally relevant concentration (...

Results on 105 cases with histopathologically confirmed non-Hodgkin's lymphoma (NHL) and 335 controls from a previously published case-control study on malignant lymphoma are presented together with some extended analyses. No occupation was a risk factor for NHL. Exposure to phenoxyacetic acids yielded, in the univariate analysis, an odds ratio of 5.5 with a 95% confidence interval of 2.7-11. M...

In the present work, the micellar electrophoretic separation of five chlorophenols (CPs) on a functionalized poly(dimethylsiloxane) (PDMS) microchip with amperometric detection was performed. In order to achieve high resolution by controlling the electroosmotic flow (EOF) as well as signal detection by suppressing analytes adsorption, the microchannel was functionalized by poly(diallyldimethyla...

INTRODUCTION The ecological risks posed by three chlorophenols (CPs), 2,4-dichlorophenol (2,4-DCP), 2,4,6-trichlorophenol (2,4,6-TCP), and pentachlorophenol (PCP) in Chinese surface waters were assessed. MATERIALS AND METHODS This was achieved by applying a tiered ecological risk assessment (ERA) approach ranging from deterministic methods to probabilistic options to measured concentrations o...

A new kind of solid-phase extraction disk based on a sheet of single-walled carbon nanotubes (SWCNTs) is developed in this study. The properties of such disks are tested, and different disks showed satisfactory reproducibility. One liter of aqueous solution can pass through the disk within 10-100 min while still allowing good recoveries. Two disks (DD-disk) can be stacked to enrich phthalate es...

Pulp paper mill pollutants are the major source of aquatic contamination having metals, lignin and chlorophenols. Study was conducted to see the effect of these contaminants on antibiotic resistance pattern of isolated bacteria. Pulp paper effluents were evaluated for its physico-chemical properties i.e, BOD 72143 +/- 164.81 to 22.32 +/- 2.48, COD 213136 +/- 583.59 to 60.40 +/- 6.34, total phen...

3D printing is a manufacturing technique used to prototype devices with customized shapes composed of different materials, including carbon composites. Toxic phenolic compounds are major environmental hazard. Herein, we demonstrate the use carbon-based 3D-printed electrodes for detection chlorophenols and nitrophenols. The influence pH on voltammetric response was studied, an alkaline identifie...

Organic halogens from chlorobleaching of kraft pulp were not as biorecalcitrant as has been assumed. Fifty percent were removed during biotreatment of wastewater, and 50% of the remaining organohalogens faded in fresh water ecosystems in 200 to 400 days. Molecular size seemed not to hinder biodegradation up to sizes of approximately 2000 daltons. Anoxic biodegradation was of prime importance fo...

OBJECTIVE To study the effect on the incidence of cancer of exposure to chemicals handled in the leather tanning industry. MATERIALS AND METHODS A case-control study was performed within a cohort of 2487 workers employed for at least six months during the period 1900-89 in three Swedish leather tanneries. 68 cancer cases (lung, stomach, bladder, kidney, nasal, and pancreatic cancers and soft ...
