The Information Content of Premanufacture Notices

The Information Content of Premanufacture Notices

Date: April 1983
Creator: United States. Congress. Office of Technology Assessment.
Description: A report by the Office of Technology Assessment (OTA) that presents the analysis of pre-manufacture notices and "reports the results of analyzing those notices for the presence or absence of the information specified by the Toxic Substances Control Act and for other items of physical chemical and toxicity information that are useful for estimating potential health and environmental effects" (p. iii).

Solvent Effects and Bioconcentration Patterns of Antimicrobial Compounds in Wetland Plants

Solvent Effects and Bioconcentration Patterns of Antimicrobial Compounds in Wetland Plants

Date: May 2011
Creator: Adhikari, Sajag
Description: This study looked at effects of organic solvents dimethylsulfoxide, dimethylformamide and acetone at 0.01%, 0.05% and 0.1% concentration on germination and seedling development wetland plants. Even at 0.01% level, all solvents affected some aspect of seed germination or seedling growth. Acetone at 0.01% was least toxic. Root morphological characteristics were most sensitive compared to shoot morphological characteristics. This study also looked at bioconcentration patterns of antimicrobial compounds triclosan, triclocarban and methyl-triclosan in wetland plants exposed to Denton Municipal Waste Water Treatment Plant effluent. Bioconcentration patterns of antimicrobial compounds varied among species within groups as well as within organs of species. The highest triclocarban, triclosan and methyltriclosan concentration were in shoot of N. guadalupensis, root of N. lutea and in shoots of P. nodous respectively.

Toxicity Studies of Aquatic Actinomycetes

Toxicity Studies of Aquatic Actinomycetes

Date: August 1952
Creator: Fair, Helena Juengermann
Description: Since Actinomycetes have been isolated from finished public drinking water, it is believed that the organisms are unaffected by the chlorination and flocculation of water treatment plants and pass as spores through the filters into the general distribution system. For this reason it was deemed imperative to study the toxic effects of these organisms.
