Pool chlorine hypothesis¶
The pool chlorine hypothesis is the hypothesis that long-term attendance at indoor chlorinated swimming pools by children up to the age of about 6–7 years is a major factor in the rise of asthma in rich countries since the late twentieth century.
Core Idea¶
Pool chlorine hypothesis is treated here as the recurring environmental epidemiology identity summarized by this source-grounded definition: The pool chlorine hypothesis is the hypothesis that long-term attendance at indoor chlorinated swimming pools by children up to the age of about 6–7 years is a major factor in the rise of asthma in rich countries since the late twentieth century. The pool chlorine hypothesis is the hypothesis that long-term attendance at indoor chlorinated swimming pools.
Scope of Application¶
-
Relations to demographic and environmental variables. Other atopic diseases such as hay fever or atopic dermatitis were found to be not associated with the presence of the pools.
-
Relations to demographic and environmental variables. The association of asthma with the number of indoor chlorinated swimming pools per 100,000 inhabitants was found by the authors to be independent of altitude, climate, and GDP per capita.
-
Scientific debate on the epidemiological studies. For example, Eggleston argued that if "chlorinated compounds at indoor swimming pools could cause asthma", then "frequent and longer exposures at home" should be even stronger causes of asthma, in contradiction.
-
Scientific debate on the epidemiological studies. Members of Bernard's group's declared that they had no potentially conflicting financial interests, while Eggleston declared that he had received money from the United States-based group called the Chlorine Chemistry Council.
-
Scientific debate on the epidemiological studies. In a "Faculty Disclosure" statement in an asthma-related publication, it was declared that Eggleston is "a consultant for Chlorine Chemistry Council, Church and Dwight, Merck Sharp & Dohme, and Procter & Gamble, and.
Clarity¶
A clear use of Pool chlorine hypothesis names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is The pool chlorine hypothesis is the hypothesis that long-term attendance at indoor chlorinated swimming pools by children up to the age of about 6–7 years is a major factor in the rise of asthma in rich countries since the late.
Manages Complexity¶
Pool chlorine hypothesis compresses multiple environmental epidemiology details into a stable diagnostic relation. The source shows both the central mechanism—for example, Eggleston argued that if "chlorinated compounds at indoor swimming pools could cause asthma", then "frequent and longer exposures at home" should be even stronger causes of asthma, in contradiction to the available evidence from a single group of children.—and the practical consequence—following publication of Bernard's group's.
Abstract Reasoning¶
- Type the carrier. Identify the environmental epidemiology entities to which the claim applies.
- State the relation. Use the source-grounded identity: The pool chlorine hypothesis is the hypothesis that long-term attendance at indoor chlorinated swimming pools by children up to the age of about 6–7 years is a major factor in the rise of asthma in rich countries since the late twentieth century.
- Check.
Knowledge Transfer¶
Within the home domain. Knowledge about Pool chlorine hypothesis transfers literally when a new case preserves the same carrier type, relation, and recognition test. Other atopic diseases such as hay fever or atopic dermatitis were found to be not associated with the presence of the pools. The association of asthma with the number of indoor chlorinated swimming pools per 100,000 inhabitants was found by.
