So far aflatoxin has not been detected in crops grown in Sweden but only in imported feedstuffs or in feed mixtures containing imported products. During the survey for other mycotoxins in Swedish crops a compound was detected in oats which, by further analysis, was identified as aflatoxin B1. Quantitative evaluation showed concentrations as high as 2.6 ppm. The fungal population in this highly contaminated sample consisted almost entirely of Aspergillus flavus.
The reuse of municipal sewage for agricultural purposes is becoming more prevalent. The literature concerning the impact of this practice is reviewed. It is readily apparent that agricultural reuse of municipal sewage is preferable to other common methods of disposal both from the point of view of ecological influence and economical waste utilization. There is a need to establish guidelines for the agricultural use of municipal sewage which will serve the variable conditions found in Canada and meet the public health concerns associated with an extensive agricultural use.
Measurements of fallout radioactivity in Greenland in 1977 are reported. Strontium-90 (and Cesium-137 in most cases) was determined in samples of precipitation, sea water, vegetation, animals, and drinking water. Estimates are given of the mean contents of 90Sr and 137Cs in the human diet in Greenland in 1977.
Measurements of fallout radioactivity in the Faroes in 1967 are presented. Strontium-90 (and 137Cs in most cases) was determined in regularly collected samples of precipitation, grass, milk, fish, sea water, bread, and drinking water. In addition, analyses were made of spot samples of lamb, sea birds, potatoes, sea plants, vegetables, eggs, and human bone. Estimates are given of the mean contents of 90Sr and 137Cs in the human diet in the Faroes in 1977.
