A study was undertaken to determine the extent of organochlorine pesticide (OP) and polychlorinated biphenyl (PCB) contamination in infant formula milk and in the human milk, fat and serum of women from an agricultural area in Southern Spain. A procedure is proposed that simultaneously detects trace levels of lindane, endosulfan-ether, vinclozolin, aldrin, endosulfan-lactone, endosulfan-alpha, ...

In recent decades, raptors have become gradually more protected in almost all European countries, but their decline often persists, due to pollution, habitat alteration and fragmentation, or to human direct/indirect disturbance (Tucker & Heath, 1994). Peregrine Falco peregrinus populations suffered a dramatic decline during the 1950s and 1960s in the boreal hemisphere, following the adoption of...

We studied the growth and capacities for pesticides removal of bacterial strains isolated from the Laguna Grande, an oligotrophic lake at the South of Spain (Archidona, Málaga). Strains were isolated from water samples amended with 10 and 50 microg/ml of nine pesticides: organochlorinated insecticides (aldrin and lindane), organophosphorous insecticides (dimetoate, methyl-parathion and methidat...

Introduction In 1950, the chemists Otto Paul Hermann Diels, from Germany, and Kurt Alder, originally born in Prussia and then moved to Germany after World War I, received the Nobel Prize in chemistry for the discovery of a new way to synthesize cyclic molecules. Aptly titled the Diels-Alder Cycloaddition Reaction, this new mechanism allowed conjugated dienes to undergo addition reactions with a...

Phosphatase activities (cell-bounded phosphatases "BP" and freely dissolved phosphatases "D P") in water samples from a natural lake "Laguna Grande" (Antequera, Málaga, Spain) amended with 50 microg/ml of selected insecticides, herbicides and fungicide captan were studied under laboratory controlled conditions (temperature and agitation). Our data show that dissolved alkaline phosphatase was th...

In this study total of 150 samples emulsion type meat products (Luncheon & Frankfurter) (75 each) were collected from local and supermarkets in Giza governorate, Egypt. Samples subjected to determination residue antibiotics, zeranol, trenbolone, heavy metals (Cadmium, lead, Zinc Arsenic) pesticides (OPPs OCPs). The proved that the incidence percent organophosphorus arsenic zero all samples, zer...
