Eighty four cases with acute chlorine poisoning who reported between 1/2 hour to 2 hours after exposure were studied. A majority presented with features of upper respiratory tract involvement like irritative cough (70 cases) and oropharyngeal pruritus (60 cases). Bronchospasm was present in 15 cases. None of them had any residual impairment of pulmonary function 4 weeks after exposure.

Chlorine-containing disinfectants have been widely used around the world for prevention and control of COVID-19 pandemic. However, at present, little is known about impact residual chlorine on soil micro-ecological environment. Herein, we treated an experimental soil-plant-microbiome microcosm system by continuous irrigation with a low concentration chlorine-containing water, then analyzed infl...

Over 1.1 billion people in the world lack access to improved drinking water. Diarrhoeal and other waterborne diseases cause an estimated 1.87 million deaths per year. The Safe Water System (SWS) is a household water treatment intervention that reduces diarrhoeal disease incidence among users in developing countries. Turbid waters pose a particular challenge to implementation of SWS programmes; ...

BACKGROUND Outbreaks of legionellosis may be a side effect of institution-water treatment. However, the long-term outcomes and the predictive factors of Legionella prevalence in such systems have still not been fully studied. This study was therefore conducted to investigate the prevalence of Legionella spp. and to evaluate the role of bacteriological water quality parameters on its prevalence ...

Changes in BET surface area and morphology of Ti02 (anatase) were studied as a function of temperature and level of chlorine contamination. The objective was to study the behavior of TiO2 supports under typical catalyst preparation and reaction conditions, using adsorption, wide angle X-ray diffraction and scanning electron microscopy. Chlorinated samples had lower surface areas compared to bla...

Since 2003, there has been significant concern about the possibility of an outbreak of avian influenza virus subtype H5N1. Moreover, in the last few months, a pandemic of a novel swine-origin influenza A virus, namely A(H1N1), has already caused hundreds of thousands of human cases of illness and thousands of deaths. As those viruses could possibly contaminate water resources through wild birds...

Background & Aims of the Study: Saveh city -located in the semi-arid area in Iran- has brackish water and it was forced to use reverse osmosis desalting systems.  Water is not distributed through the distribution network to homes so, people have to buy water from certain places and transfer water through household storage vessel. They have to buy more water and keep it at home for more than 1 w...

Chlorine is the most widely used disinfectant worldwide, partially because residual protection is maintained after treatment. This residual is measured using colorimetric test kits varying in accuracy, precision, training required, and cost. Seven commercially available colorimeters, color wheel and test tube comparator kits, pool test kits, and test strips were evaluated for use in low-resourc...
