Millions of people worldwide enjoy swimming pool activities every year. Traditionally, chlorine-containing chemicals have been used as the sanitizing agent. Some chlorine containing chemicals used include chlorine gas, sodium hypochlorite, calcium hypochlorite, lithium hypochlorite, and chlorinated isocyanurates. These chemicals enter the pool as a concentrated solution, or in the form of hypoc...

The present study describes the main actions in Finnish nutrition policy during the past decades. The main actor is the National Nutrition Council, which provides nutritional recommendations and action programmes, and sets up expert groups to solve nutritional problems in the population. The main fortification programmes have been the iodization of table salt, supplementation of selenium to fer...

BACKGROUND Iodine content in table salt was adjusted from 30-50 mg/kg to 21-39 mg/kg from March of 2012 in Henan Province, China. The vulnerable population may be at risk of iodine deficiency. OBJECTIVES To determine whether the iodine intake was sufficient in vulnerable populations and to investigate what factors may be associated with iodine status in these vulnerable populations in Henan P...

A sensitive spectrophotometric method for the determination of iodine species like iodide, iodine, iodate and periodate is described. The method involves the oxidation of iodide to ICl(2)(-) in the presence of iodate and chloride in acidic medium. The formed ICl(2)(-) bleaches the dye methyl red. The decrease in the intensity of the colour of the dye is measured at 520 nm. Beer's law is obeyed ...

OBJECTIVE To determine the iodine content of iodized salt at the production stage, to assess the perceptions and knowledge of salt producers about the prevention and control of iodine deficiency, and to examine the internal quality control procedures used during iodization in South Africa. METHOD Salt samples were collected for iodine analysis by titration from the 12 producers iodizing salt ...

Iodine deficiency disorder (IDD) is currently an important public health problem in Turkey. The use of iodized salt is a sample and cheap solution. The purpose of this study was to determine the prevalence of iodized salt use in the Trabzon region and the effect of a local mass-media education program in increasing usage. The overall aim was to use the findings to inform future health managemen...

Amajor difficulty in determining the mechanisms responsible for human hypertension is the great variety of systems involved in regulating blood pressure and our tendency to assume that these mechanisms are similar in all hypertensive patients. Even when patients are separated into those whose blood pressure is or is not sensitive to the level of sodium intake, it is often assumed that all "salt...

BACKGROUND Most US adults consume excess sodium. Knowledge about the dietary sources of sodium intake is critical to the development of effective reduction strategies. METHODS A total of 450 adults were recruited from 3 geographic locations: Birmingham, AL (n=150); Palo Alto, CA (n=150); and the Minneapolis-St. Paul, MN (n=150), metropolitan areas. Equal numbers of women and men from each of ...

Hypertension is defi ned as a systolic blood pressure (BP) of 140 mmHg or higher or a diastolic BP of 90 mmHg or higher.1 However, health declines in persons whose blood pressure is above 115/75 mmHg. Hypertension is linked to an increased risk of stroke, myocardial infarction, heart failure, renal failure, and cognitive impairment.1,2 Globally, a systolic BP above 115 mmHg is the top determina...

Poor iron status affects 50% of Indian women and compromises work productivity, cognitive performance, and reproduction. Among the many strategies to reduce iron deficiency is the commercial fortification of iodized table salt with iron to produce a double-fortified salt (DFS). The objective of this study was to test the efficacy of DFS in reducing iron deficiency in rural women of reproductive...
