One case of Severe Inhalational Toxicity from Chlorine Dioxide
One case of Severe Inhalational Toxicity from Chlorine Dioxide
This is a case report of prolonged Cl02 exposure resulting in injury to the lungs, eyes, and peripheral nerves of a 35-year-old man. Severe inhalational injury from Cl02 can affect multiple organ systems and may be resistant to treatment as in this case. Constrictive bronchiolitis obliterans is suspected with continued worsening in his PFTs, hypoxia, and functional class since exposure despite a normal HRCT without biopsy.

Use of Hypochlorite Solution as Disinfectant during COVID-19 Outbreak in India: From the Perspective of Human Health and Atmospheric Chemistry - Aerosol and Air Quality Research
The current situation in India regarding the COVID-19 pandemic is the worst since its first detection, in terms of the number of new cases per day, and it is now more than 10000 (as of June 7, 2020). In addition to several precautionary steps being taken (social distancing, use of masks, sanitizing hands etc.), spraying disinfectants (NaOCl solution) over several residential, official and commercial buildings, open areas, markets, public road transports, railways etchas been occurring on a regular basis. It has also cometo the world’s attention that spraying of disinfectants has been especially used on people who are migrating from one part of the country to another. In this letter, I have made an attempt to discuss some major impacts of NaOCl on human health as well as atmospheric chemistry. NaOCl once emitted into the air reacts easily with the water vapor to form HOCl that further gets photo-dissociated into various reactive species. These reactive species have significant potentials to participate in various tropospheric chemistry of chlorine radical, ozone, S (IV) oxidation, hydrocarbon oxidation, modification of chloride salts etc. I have also recommended some important steps to be taken if spraying of NaOClis deemed essential.

Chlorine dioxide inhalation studies
****!!!!**** The main lesion induced by ClO2 is the destruction of alveolar walls, which creates pulmonary emphysema lesions. This emphysema was found on all rats of the study (except control) whatever the tested concentration. The severity of the lesion is proportional to the dose. Animals died by respiratory deficiency. LC50combined = 89 mg/m3air

Reduced oxidative power but unchanged antioxidative capacity in skeletal muscle from aged humans - PubMed
The hypothesis that the aging process is associated with mitochondrial dysfunction and oxidative stress has been investigated in human skeletal muscle. Muscle biopsy samples were taken from seven old male subjects [OS; 75 (range 61-86) years] and eight young male subjects [YS; 25 (22-31) years]. Oxi …

Six-month low level chlorine dioxide gas inhalation toxicity study with two-week recovery period in rats
Six-month low level chlorine dioxide gas inhalation toxicity study with two-week recovery period in rats
2012. Chlorine dioxide (CD) gas has a potent antimicrobial activity at extremely low concentration and may serve as a new tool for infection control occupationally as well as publicly. Long-term, low concentration CD gas inhalation toxicity was studied in rats as a six-month continuous whole-body exposure followed by a two-week recovery period, so as to prove that the CD gas exposed up to 0.1 ppm (volume ratio) is judged as safe on the basis of a battery of toxicological examinations. No CD gas-related toxicity sign was observed during the whole study period. No significant difference was observed in body weight gain, food and water consumptions, and relative organ weight. In biochemistry and hematology examinations, changes did not appear to be related to CD gas toxicity. In necropsy and histopathology, no CD gas-related toxicity was observed even in expected target respiratory organs.

Oxidation-Reduction Potential as a Biomarker for Severity and Acute Outcome in Traumatic Brain Injury
Oxidation-Reduction Potential as a Biomarker for Severity and Acute Outcome in Traumatic Brain Injury
There are few reliable markers for assessing traumatic brain injury (TBI). Elevated levels of oxidative stress have been observed in TBI patients. We hypothesized that oxidation-reduction potential (ORP) could be a potent biomarker in TBI. Two types of ORP were measured in patient plasma samples: the static state of oxidative stress (sORP) and capacity for induced oxidative stress (icORP). Differences in ORP values as a function of time after injury, severity, and hospital discharge were compared using ANOVAs with significance at . Logit regression analyses were used to predict acute outcome comparing ORP, Injury Severity Score (ISS), Abbreviated Injury Scale (AIS), and Glasgow Coma Scale (GCS). Antioxidant capacity (icORP) on day 4 was prognostic for acute outcomes (). An odds ratio of 4.08 was associated with poor acute outcome when icORP > 7.25 μC. IcORP was a better predictor than ISS, AIS, or GCS scores. sORP increased in those with the highest ISS values (). Based on these findings ORP is useful biomarker for severity and acute outcome in TBI patients. Changes in ORP values on day 4 after injury were the most prognostic, suggesting that patients’ response to brain injury over time is a factor that determines outcome.
