Concentrations of Mo, Cu, Zn, Mn, Fe, N, Ca, P, Mg and K were determined in native and introduced grasses and legume forages from throughout northwestern Manitoba. Nutrient concentrations were compared with minimum requirements of cattle suggested by the Agricultural Research Council and the National Academy of Sciences–National Research Council. Differences in Mo concentrations were noted in forages between two geologic subareas within the study area. Cu and Mo concentrations suggested potentials for primary Cu deficiency in grasses throughout the region, and for Mo-induced Cu deficiency with grasses west of the Swan River formation and with legumes from all areas within the region. Throughout the study area, concentrations of Zn and Mn were found to be at deficient levels while those of Fe and Ca were found to be at adequate to excessive levels for cattel production. N and P concentrations in all forages were borderline to adequate, while Mg and K concentrations of grass forages were deficient to borderline with relation to the requirement of cattle.

Samples of barley, oat and wheat grain, barley, oat, barley–oat, grass, legume and grass–legume roughage grown throughout Alberta were analyzed for Fe, Mn, Cu and Zn concentrations. In addition, the barley grain and grass–legume roughage samples were analyzed for Se concentrations. The various element concentrations were compared with Agricultural Research Council and National Academy of Sciences–National Research Council minimum requirements for cattle. The geographic distribution of these concentrations within Alberta was also examined. The mean Fe concentrations for all feeds were well above the suggested minimum requirement of 30 ppm. On the other hand, the mean Zn concentrations for all feeds were below the suggested minimum requirement of 50 ppm. Mean Mn concentrations of barley grain, barley roughage and legume roughage were less than the suggested minimum requirement of 40 ppm. Wheat grain was the only feed showing a mean Cu concentration of less than the suggested minimum requirement of 10 ppm. Mean Se concentrations of barley grain and grass–legume roughage were above the suggested minimum requirement of 100 ppb. With the exception of Se in barley grain there were no geographic differences in elements evident within Alberta. Selenium in barley grain showed highest concentrations in the south and southeast of the Province with greater occurrence of low concentrations towards the west, north and northwest.

The Committee on Human Factors, a standing committee of the National Academy of Sciences/National Research Council (NAS/NRC), advises its sustaining sponsors and other requesting organizations on issues involved in the design of socio-technical systems and on the research and methods needed to help enhance their operability and safety. This paper describes the origins, purposes, operations and program of the committee and emphasizes the special attributes of this and other NAS/NRC commtittees.

Required monitoring of the physical, biological and chemical condition of the nearshore waters of the ocean receiving treated wastewaters has been underway in the U.S.A. since 1955 or about 35 years. When established the stated intent had been to utilize the information obtained to evaluate the effects of the diffusion of wastewaters upon the beneficial values of these receiving waters. That is upon the food web including game and food fish; upon water contact sports uses; upon aesthetics; and upon the local, regional, and worldwide ecology. To this end original requirements had included a provision that the regulatory agency reduce the data obtained from the monitoring effort to information useful to themselves as well as to facility design and operational authorities. Inasmuch as the monitoring effort in 1989 was using funds in excess of 130 million dollars per year and had a 35 year data base, the Marine Board of the National Research Council - National Academy of Sciences: National Academy of Engineering established committees of scientists to evaluate the progress of the national monitoring effort and of the longest and most complete program of the Southern California Bight. It was found that the essential portion of the program, that of reducing the data obtained to usable information, had not been carried on so that approximately 35 years of data existed with little to zero information. In addition the data existed in pools of intensive samplings around discharge points with very little overall study of the coastal waters. Whether the discharge points were significantly different from the “normal” coastal waters was not really known because “normal” was not known. The Committees recommended procedures to follow to rectify these basic problems including reallocation of current funding to cover the research, control, design and operational needs. Their findings are summarized in the paper.
