Chlorine dioxide (ClO2) is an antimicrobial recognized for its disinfectant properties since the early 1900's (EPA, 2005). This compound effectively kills microorganisms including bacteria, viruses or fungi on inanimate objects, foods, and other surfaces (EPA, 2005). Chlorine dioxide can be generated in a gas or liquid form and smells like chlorine bleach (EPA, 2005). In 1967, the Environmental...
Chlorine as a micronutrient has a positive effect on the quality of tobacco leaves. However, the more chlorine has adverse effects on tobacco quality. To study the genetic accumulation of chlorine in leaves of oriental tobacco, each of the two lines ‘Basma 16-10’ and ‘SPT 406’ with the low accumulation of chlorine were crossed separately with Basma S. 31 with the high accumulation of chlorine. ...
Many toxic industrial chemicals (TICs) such as chlorine and ammonia are very reactive with commonly encountered materials in the environment. The amount of TIC material reacted environment is an important factor determining impact a release. Typically characterized dry deposition rate atmospheric dispersion models, reaction has predominately been studied field scale experiments at concentration...
a methodology is presented in this paper to find optimal location and dosage of chlorine injection in water distribution networks. the objective is to minimize the chlorine consumption while keeping the residual chlorine at each node within the standard range. unfortunately because of wrong water quality management in water distribution networks in many parts of the world, many problems such as...
Although 2% glutaraldehyde is often the first-line agent for endoscopic disinfection, its adverse reactions are common among staff and it is less effective against certain mycobacteria and spore-bearing bacteria. Chlorine dioxide is a possible alternative and an automated washer-disinfector fitted with this agent is currently available. This study was conducted to evaluate the effectiveness of ...
Environmental and patient isolates of Mycobacterium avium were resistant to chlorine, monochloramine, chlorine dioxide, and ozone. For chlorine, the product of the disinfectant concentration (in parts per million) and the time (in minutes) to 99.9% inactivation for five M. avium strains ranged from 51 to 204. Chlorine susceptibility of cells was the same in washed cultures containing aggregates...
Measurements of chlorine concentrations in matrix glasses from 18 primitive (s 6 wt% MgO) and eight evolved lavas from active spreading centers in the Lau Basin back-arc system provide insight into the processes which control chlorine concentrations in subduction-related magmas, and can be used to investigate chlorine enrichment related to fluids derived from the underlying subducted slab. Chlo...
