Epidemiological monitoring in the vicinity of a coal-fired power plant

An epidemiological monitoring program has been designed and put into operation in response to a health monitoring requirement of a permit to build a coal-fired power plant. It will consist of four 350 megawatt units and is being built on the Mediterranean coast about halfway between Tel-Aviv and Haifa; the first unit became operational in 1981.The resident population within a 10 km. radius consists of about 69,000 persons. The permit to build this power plant required the installation of a comprehensive monitoring network including environmental, health and agricultural monitoring. Four types of studies are included in the epidemiological monitoring program: mortality analyses, monitoring of requests for health services, studies of pulmonary symptoms and lung function in school children, and panel studies of children and adults with chronic pulmonary conditions. Areas of maximal expected exposure risk and two other comparable areas of lesser risk were chosen, based on expected emissions, meteorological and topographical considerations; baseline data were gathered for a year prior to the operation of the first unit of the power plant. Subsequent data are planned to be collected for another 10 years. The program permits detection of short-term effects based on increases in health service requests, medium-term effects by repeat examination of panelists, and long-term effects based on pulmonary conditions among school children. The initial survey, before plant operations showed, among other things, lower flow rates for children in the area expected to have medium levels of exposure.     

Mercury emissions from a coal-fired power plant in Japan

The emissions study for mercury was conducted at a 700 MW coal-fired plant for the combustion of three types of coal with mercury concentrations of 0.0063, 0.0367 and 0.065 mg/kg. The power plant is equipped with a cold-side electrostatic precipitator and wet type flue gas desulfurization system. During full load operation of the boilers, samples of the input and output streams such as coal, coal ash, ESP ash and post-ESP particulates and flue gas were collected. The Hg concentrations in solid were measured by cold-vapor atomic absorption spectrometry (AAS) after appropriate preparation and acid digestion. Gaseous Hg was collected using a mixed solution of potassium permanganate and sulfuric acid and the Hg concentrations in the samples were measured using cold-vapor AAS. The results were used to examine: (1) overall mass balances; (2) relative distribution in the power plant; (3) equilibrium of Hg species using MALT-2 calculation program; and (4) Hg concentrations in stack emissions. The mass balances estimated in this study were 100, 138 and 89%, respectively, for the coals. Total Hg concentrations in stack gas were 1.113, 0.422 and 0.712 microg(m3N), respectively, for the coals. More than 99.5% of the Hg in the stack emissions were in gaseous form and the proportion in particulate form was extremely low. The relative distribution of Hg in ESP, FGD and Stack ranged from 8.3 to 55.2%, 13.3 to 69.2% and 12.2% to 44.4%, respectively. The results indicated that factors other than the Hg concentration of coals and efficiency of pollution control devices might affect Hg emissions from coal-fired plant. The calculated equilibrium of the distribution of Hg species using the MALT2 program suggest that it is necessary to consider condensation mechanism to interpret the affect of Hg species on the variations of the removal efficiencies of Hg in the ESP.

Investigations on fly-ash and soil samples in the environment of a coal-fired power plant

In the main wind direction of a coal-fired power plant dust and soil samples have been collected to analyse the content of fly-ash coming from the power plant. The fly-ash particles are spherical and contain the natural radionuclides mainly Ra-226, Pb-210, Po-210 and K-40 in a higher concentration when compared with the original coal. The investigation of soil samples results in increased Pb-210 and Po-210 concentrations when compared with the natural environment. By presence of spherical particles in dust and soil samples the power plant can be identified as the emitter.
