A Study Of Human Exposure To Benzo(A)Pyrene (Bap) Through Different Pathways. Part A ; Assessment Of Benzo(A)Pyrene (Bap) Exposure Through Urine Analysis With The Hydriodic Acid Reduction Reaction. Part B, Shao-Keng Liang

Theses

PART A: An investigation of total human exposure to an environmental pollutant is described. The study is being conducted in a community impacted by a foundry suspected to be a dominant local source of benzo(a)pyrene (BaP). The research aims to assess the relative contributions of indoor and outdoor sources and to measure BaP in media including indoor air, outdoor air, food and water.

PART B: A method for biological monitoring of exposure to benzo(a)pyrene, a representative polycyclic aromatic hydrocarbon (PAH), has been developed. The analytical procedure includes extraction of PAH and PAH metabolites from urine using commercial cartridges containing c …

Analysis Of C2 And C3 Hydrocarbons In Ambient Air. Section I ; Identification And Quantification Of Volatile Organics Emitted From A Landfill. Section Ii, Tsong-Sheng Chang

Theses

SECTION I

A method was developed to analyze Acetylene, Ethylene, Ethane, Propylene and Propane levels in the ambient air. Chlorinated compounds within the operation retention time, Methyl chloride, Methylene chloride and Vinyl chloride, were monitored also.

Four sampling sites are located at Carteret, Elizabeth, Newark and Montville in New Jersey. Samples were taken during the summer of 1988. Two sample duration periods utilizing 12 and 6 liter stainless steel canisters were set up to take 24 hour air samples and instantaneous air samples (5 minutes collection period).

The average levels of Acetylene, Ethylene, Ethane, Propylene and Propane at the four …

State Of The Fisheries Report 1987, Fisheries Department Of Western Australia

Status Reports of the Fisheries and Aquatic Resources

Western Australia continues to be one of the leading fishing States in Australia. The total gross value of fish, crustaceans and molluscs for 1986/87 was $172 million (Table 1) to which may be added the value of the pearl culture industry resulting in a total value of approximately $213 million.

The Effect Of Preozonation On The Anaerobic Biodegradability Of Resistant Phenolic Compounds, Yi-Tin Wang, Pin-Chieh Pai, James L. Latchew

KWRRI Research Reports

Ozone pretreatment studies of four model phenolic compounds were conducted to evaluate the effects of ozonation on the anaerobic biodegradability and toxicity of these compounds. Two types of batch studies, the Biochemical Methane Potential (BMP) and the Anaerobic Toxicity Assay (ATA), were performed on samples ozonated upon phenol, o-cresol, 2,5-dichlorophenol, and 2,4-dinitrophenol.

Experimental results showed that toxic and refractory phenolic compounds were converted to methane gas by means of preozonation. In general, the biodegradable fraction of the oxidation products increased as the ozone dose was increased. However, ozonation to achieve at least 60% COD reduction was necessary to faciliate methane …

Indian reservations constitute about 2.5% of all land in the country and 5% of all land in the American West. During the last two decades, Indian natural resources issues have moved to the forefront as tribal governments have dramatically expanded their regulatory programs, judicial systems. and resource development activities. This major symposium will address current developments and assess likely future directions in the areas of tribal, federal, and state regulation; tribal-state intergovernmental agreements; financing; mineral …

Protecting water quality is essential to preserve the many beneficial uses of western water resources. This conference addresses the dominant federal requirements in the Clean Water Act, including the important major revisions enacted by Congress in 1987, with special attention to western problems regarding nonpoint source pollution. Developments in groundwater quality regulation are considered, as are selected issues concerning the implications of state and federal water quality regulation for the traditional exercise of water rights.
