Abstract
Four eutrophicated lakes situated on the Danish island of Lolland were investigated. The result of chemical analyses of the water, and the determination of heavy metals in the sludge by means of flameless atomic absorption spectrophotometry are given in the tables 1–5.
Bacteriological investigations of sediments from the lakes, both conventional analyses and also more special analyses, e.g. of cellulolytic bacteria, chitinoclastic bacteria; lignin decomposing actinomycetes were counted on both tannic acid agar and gallic acid agar, and saprophyticActinomyces on Henrici’s asparagine substrate, tables 6–9.
