摘要:

Studies were undertaken to examine the interaction between polychlorinated biphenyls (PCB's) and soil. Both field samples and laboratory prepared samples were examined. Samples of soil were taken from the 0.7 m depth at a transformer producing industry at which PCB spills had occurred. These were extracted to determine their PCB content. Concentrations ranged from 0.1 to 41.7μg PCB (as Aroclor 1254)/g soil.

摘要:

The rate of movement of certain potential pollutants (e.g. heavy metals and organic carbon) found in municipal solid waste (MSW) landfill leachates is correlated with certain measurable broad parameters of both the leachate and soil. Those most prominent leachate characteristics fall into broad categories such as total organic carbon compounds (TOC), pH, and concentration of soluble common salts and some naturally occurring metals, notably iron. Usually, the lower the pH level and higher the concentration of the other constituents, the more rapid is the movement of the pollutants through soil. Therefore the behavior of MSW leachate with respect to its influence on attenuation of heavy metal migration through soils is not the same generated from freshly deposited waste as from that deposited longer.

摘要:

Persons with glucose‐6‐phosphate dehydrogenase (G‐6‐PD) deficiency reoresent a group at increased risk to hemolytic anemia from a variety of industrial and therapeutic chemical agents. The possible role of chemicals in the ambient air and water as potential causes of hemolytic episodes in the G‐6‐PD deficient condition has not been investigated. One potential oxidant stressor is sodium chlorite which may be found in drinking water disinfected with chlorine dioxide. This is a disinfectant widely used in Europe and presently being considered for application in the U.S.A. by the Environmental Protection Agency.

摘要:

The analysis of corrosion inhibitors, such as morpholine (MOR), cyclohexylamine (CHA), diethylaminoethanol (DEAE) and octadecylamine (ODA) in steam condensates sampled in four hospitals and one food processing plant, is described. An aqueous injection‐gas chromatographic procedure was developed for the analysis of DEAE; mixtures of CHA and MOR were determined by a similar method. ODA was quantitated by a colorimetric method. Levels of amines were consistently low (4.2 mg/L) in steam sampled in systems in which the addition of amines to the boiler feed water was continuously metered. In a closed‐loop, low pressure system in which the amine formulation was added in a single dose to the boiler in an irregular manner, concentrations of amines in steam condensates were high (10,200 to 13,900 mg/L).

摘要:

Experiments were carried out on the gasification‐combustion of organic solid wastes to determine the effect of process parameters on the contaminants emissions. Solid municipal waste and wood waste material were gasified under reactive environments in a stirred reactor. The important parameters were found to be temperature, residence time, and moisture content of the fuel. With increasing temperature, the amount of particulate matter, smoke, and hydrocarbon emissions decreased. It was found as the temperature exceeded 800° C, the discharge of air pollutants from the combustion of waste material was drastically reduced. The results was then used to determine the pollution burden of applying incineration as a mean of Tehran municipal waste disposa1.
