The study was induced by increased beta-HCH contaminations in milk fat and beaf in a food screening study in spring 1990. It was shown that the beta-HCH came into the ecosystem largely by sewage from the Bitterfeld chemical industry as a refuse product from the former production of LINDANE. The possible paths are discribed by means of the donator-a...
Repellents substances and devices cause pest species to avoid otherwise attractive or palatable materials. For birds, repellents can be visual, auditory, pyrotechnic, tactile, chemosensory, physiologic, or physical. Here, we consider chemical agents only. Few substances are registered with the U.S. Environmental Protection Agency (EPA), and thus le...

An increase of proto-oncogene c-fos expression in cerebral cortex of rats treated with subconvulsant doses of the pesticide organochlorine lindane (gamma-hexachlorocyclohexane) has been detected using Northern blots. Immunohistochemical studies show that Fos protein was already increased in neuronal nuclei 3 h after treatment. The administration of...

La toxicité du cadmium, du plomb, et d'un insecticide, le lindane (Gammalin 20) a été testée sur le bivalve d'eau douce #Egeria radiata$ Lamarck au cours de quatre incubations de 96 heures chacune. Auune mortalité n'a été notée dans les témoins. Dans tous les tests l'effet de la concentration est apparu. Les LC 50 pour 96 heures ont été de 21,4 mgl...
Im Teil 1 der Arbeit werden Versuche zum Verhalten und Zerfall von nicht wasserdampf-fluechtigen chlorierten Kohlenwasserstoffen (CKW) (chlorierte Phenole und Benzole, Lindan) beschrieben. Dabei wurde das Austragsverhalten der CKW ueber die Wasserphase, die Auswirkungen der CKW auf anaerobe/aerobe Abbauvorgaenge im Deponiekoerper, die Bildung von M...
