Centraal Laboratorium TNO (author), Ritter, F.J. (author)T.N.O. has been active in pheromone research since the late 1960s. The emphasis was originally on isolation and identification. T.N.O. research resulted in the identification of trail pheromones of termites and an ant, sex pheromones of 7 lepidoptera and a cockroach, the alarm pheromones of several aphids, aggregation pheromones of cockroaches...article 1988

Besemer, A.C. (author), Kanij, J. (author), Centraal Laboratorium TNO Hoofdgroep Maatschappelijke Technologie (author)The leachability of polycyclic aromatic hydrocarbons from coal ash into aqueous systems was studied. Carbon-14-labeled 3,4-Benzopyrene (BaP) was deposited on coal fly ash by adsorption from the liquid phase in quantities of about 10 ??g/g ash. After a thermal treatment in air at 120??C for 2 hours the desorption of BaP was measured using aqueous...article 1984

Kuiper, J. (author), Hanstveit, A.O. (author), Centraal laboratorium TNO (author)The fate and effects of 4-chlorophenol (4CP) and 2,4-dichlorophenol (DCP) added to North Sea coastal plankton communities enclosed by large plastic bags were studied in three experiments of 4 to 6 weeks duration. The biodegredation of the compounds was studied in laboratory experiments using water from the enclosed ecosystems 4CP and DCP, added...article 1984

(author), Hoofdgroep Maatschappelijke Technologie Centraal Laboratorium TNO (author)FIy ash from fluidised bed combustion of bituminous coals contains carbonaceous cenospheres of several forms including thick-walled opaque, transparent with a skeletal structure and 'balloons' without skeletons. The influence on cenosphere formation of particle size, temperature, heating rate, petrographic composition, etc. is reviewed. The...article 1984

Centraal Laboratorium TNO (author), Compaan, H. (author)In 1972 the Convention for the prevention of marine pollution by dumping from ships and aircraft was signed in Oslo. In this convention a distinction was drawn between a black list of substances not to be dumped and a grey list of substances to be dumped only when a certain rules are observed. However, no detailed explanation of the terms...book 1980
