Observations on work force and training needs for assessing environmental health risks.

Abstract

The continuing discoveries of hazardous waste sites have stimulated environmental health risk assessment efforts in State and local environmental health agencies. Elements of risk assessment are defined, showing how risk assessment interfaces with risk management. Environmental health risk assessment involves work components (tasks, activities, and technologies), the worker (position, classification, and occupation), and work organization (purpose, outputs, and objectives). Information from six State agencies was used to describe current State government experiences with environmental health risk assessment. Education and risk assessment are described, particularly as they relate to schools of public health and the role of continuing education for the public health work force.

Natural radioactivity intake into wheat grown on fertilized farms in two districts of Pakistan.

The use of phosphate fertilizers on agricultural farms enhances gamma-ray activity concentration in the farms and therefore absorbed dose rates to the public. The most common natural radionuclides in fertilizer and soil are (40)K, (226)Ra and (232)Th. Agricultural farms at four locations in two districts in Pakistan consisting of saline and normal soils had been under fertilizer treatment for the past 30, 20, 10 and 0 y, therefore, natural radioactivity has been measured in soil samples from these sites to investigate the effect of fertilizers in soil and wheat grown in these sites. Radioactivity measured in soil of the sites under investigation was 550-644, 20-35 and 42-58 Bq kg(-1) for (40)K, (226)Ra and (232)Th, respectively. Wheat was grown in the farms and radioactivity transferred from soil to roots, shoots and grains was also measured. Relatively high natural radioactivity has been observed in the fertilized agricultural farms and in the wheat plants grown in these farms. From the total amount of an element uptaken in a plant, distribution of the element in different parts of the plant has been studied. The distribution of potassium was almost uniform in roots, shoots and grains of wheat; that of radium was different in the three parts of wheat; and that of thorium was almost equal in shoots and grains but quite large in the roots. Soils to grain transfer factors of the natural radionuclides have been determined as 3-4 x 10(-2) for (226)Ra, 2-3 x 10(-2) for (232)Th and 17-20 x 10(-2) for (40)K. Annual doses of (40)K and (226)Ra received by intake of grain products have been estimated to lie within range while the dose received from intake of (232)Th is larger than the range specified in UNSCEAR report 2000.
