in order to evaluate the effectiveness of the iranian made charcoal tubes in the field , 60 local made and 60 imported ones (skc type) were randomly selected and placed side by side for sampling aromatic hydrocarbons (including benzene, toluene, xylene) in workers breathing zone in a paint factory. the results indicated that there were no statistically significant differences between the mean c...

Charcoal-yeast extract agar is a new bacteriological medium that supports excellent growth of the Legionella pneumophila. It results from modifications made in an existing L. pneumophila medium, F-G agar. Yeast extract, instead of an acid hydrolysate of casein, serves as the protein source. Beef extractives and starch are not added. Activated charcoal (Norit A or Norit SG) is included at 0.20% ...

In our earlier investigation, a fungal isolate Penicillium citrinum VFI-51 and its secondary metabolite was reported to have antagonistic potential against Botrytis cinerea, the causative agent of Botrytis gray mold disease in chickpea. In the present investigation, P. citrinum VFI-51 was further evaluated for its antagonistic potential against Macrophomina phaseolina, the causative agent of ch...

The extraction of steroids from urine with the usual organic solvents is accompanied by the extraction of undesirable pigments which complicate the isolation of urinary steroids by paper chromatography. Even after preliminary fractionations by paper chromatographic techniques, Burton et al. (1) found that the residues were highly pigmented and bulky. This made the task of detecting minute amoun...

The production technology of high-quality vodka used in Russia involves filtration through activated charcoal. To approach the quality of renowned Russian vodka, one prominent Czech spirit-producing company inst...

The experimental materials comprised 800 Cobb 500 broiler chickens. One-day-old chickens of both sexes were randomly allocated to two feeding groups, each with four replicates of 100 birds. The chickens were reared for six weeks on deep litter and were fed standard pelleted diets in a three-stage system (starter, grower and finisher). Control group (I) birds received basal diets and experimenta...

A new type of activated charcoal for the direct hemoperfusion (DHP) has been developed for use in treatment of fulminant hepatic failure. Bead-type activated charcoal from petroleum pitch (BAC) was coated with polyetherurethane. The coating has permitted the charcoal to minimize the number of released microparticles and yet to show nearly the same adsorption performance as that of the non-coate...

A new kind of low-cost syntactic adsorbent from bamboo charcoal and chitosan was developed for the removal of microcystin-LR from drinking water. Removal efficiency was higher for the syntactic adsorbent when the amount of bamboo charcoal was increased. The optimum dose ratio of bamboo charcoal to chitosan was 6:4, and the optimum amount was 15 mg/L; equilibrium time was 6 hr. The adsorption is...

BACKGROUND Tasks involved in traditional charcoal production expose workers to various levels of charcoal dust and wood smoke. This study aimed to identify specific tasks influencing lung function and respiratory symptoms. METHODS Interviews, direct observation, and task/symptom checklists were used to collect data from 50 charcoal-production workers on 3 nonwork days followed by 11 workdays....
