Biological Indices of Stream Pollution

Biological Indices of Stream Pollution

Date: August 1952
Creator: Russell, James C.
Description: A thorough biological survey and evaluation is a lengthy and expensive project. The number of technically trained persons required prevent its use by most public agencies. Since public health departments are the groups most frequently concerned with measuring the effects of pollution in streams, a need exists for a simplified method of sanitary survey. Recognizing this need, the Texas Heal Department assigned the writer the problem of devising a method of survey which would require a field party of two and could be conducted entirely from a mobile field laboratory.

Effects of Antigen Injection on Titer of C'3 and C'4 Complement Components of Rat Serum

Effects of Antigen Injection on Titer of C'3 and C'4 Complement Components of Rat Serum

Date: August 1957
Creator: Whalen, Paul Lorrance
Description: This work attempts to establish some phenomenon of a rise in titer of C'3 and C'4 due to antigenic stimulation. Normal level of complement is established and compared to other workers as well as against guinea pig levels. Young rats were bled to establish normal levels of complement. The animals were then injected with an antigenic substance and after a period of seven days were bled again to determine the level of complement. Various antigenic and non-antigenic substances were used as well as normal saline injections for control.

The Effects of Common Electrolytes on Growth and Development of Selected Species of Aquatic Actinomycetes

The Effects of Common Electrolytes on Growth and Development of Selected Species of Aquatic Actinomycetes

Date: August 1959
Creator: Sissom, Stanley L.
Description: The role that aquatic actinomycetes play, in the production of tastes and odors in water supplies has been investigated since 1948. The ability of these organisms to produce by-products in lakes and streams, which renders the water unpalatable, is of considerable public health importance. It is desirable that the waterworks industry has as much information as possible concerning the factors that contribute to the growth of these organisms. Since it appears that the aquatic actinomycetes may be isolated from most fresh-water sources, the problem of diversified environments and nutritional requirements offers an excellent field of investigation. The fresh-waters of the world contain variable quantities of electrolytes that may determine in part the biological activity of these organisms. The unsolved questions in this instance are concerned with the electrolytes present and their quantitative effects on the growth and development of these forms.
