Changes in the content of DDT and its derivatives during the production and storage of raw smoked sausages: Changes in the content of DDT and its derivatives during the production and storage of raw smoked sausages. Gawecka, Janina (Inst. Towrozn., Akad. Elektrotekh., Poznan 60-697, Pol.). Przem. Spozyw., 37(7), 312-14 (Polish) 1983. CODEN: PRSPAD. ISSN: 0033-250X. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) Section cross-reference(s): 4, 5 The level of total DDT [50-29-3] in minced meat for sausage prodn. was 0.4002 mg/kg fat; the concn. 50-29-3 and 72-54-8 which are cas registry numbers are also used here. of DDT increased during ripening and smoking stages of sausage manuf. (to 0.453 and 0.4528 mg/kg fat, resp.) and decreased with storage in fat (0.3192, 0.2757, and 0.2529 mg/kg fat after 10, 20, and 40 days of storage, resp.). The levels of p,p'-DDT, o,p'-DDT [789-02-6], DDE [72-55-9], and DDD [72-54-8] in raw smoked sausage were 0.0449, 0.0427, 0.0697, and 0.0959 mg/kg fat after 40-day storage in fat. .

Liquid paraffins in feed enhance fecal excretion of mirex and DDE from body stores of lactating goats and cows: Liquid paraffins in feed enhance fecal excretion of mirex and DDE from body stores of lactating goats and cows. Rozman, Karl; Rozman, Tibor; Smith, G. Stanley (Abt. Toxikol., Ges. Strahlen- und Umweltforsch. m. 544-76-3 and 72-55-9 are cas registry numbers. These chemicals are also mentioned in this article.b.H. Muenchen, Neuherberg D-8042, Fed. Rep. Ger.). Bull. Environ. Contam. Toxicol., 32(1), 27-36 (English) 1984. CODEN: BECTA6. ISSN: 0007-4861. DOCUMENT TYPE: Journal CA Section: 18 (Animal Nutrition) Lactating goats given light mineral oil at 5% of feed 14 days after dosing with mirex [2385-85-5] had an ~2-fold increase in fecal mirex level and no appetite changes. Hexadecane [544-76-3] at 5% of the feed also increased fecal mirex. There was little change in milk and blood levels of mirex of exptl. goats, probably due to insufficient time for sufficient redn. of total body dosages. Cows receiving p,p'-DDE [72-55-9] from an unknown source showed increased fecal DDE levels but little change in milk and tailhead adipose tissue DDE levels after 30-70 days of mineral oil feeding (3% of feed; sprayed on feed conc.). .
