“…Our results indicated that the ratio a-/c-HCH varied from 176,888.0 (liver-dry season) to 1.0 (liver-rainy season) that reflects, respectively, an old and recent animal exposure to Lindane due to an intensive and extensive pesticide application during the rainy season, as low ratios, particularly below one, indicate recent input. According to Lorber et al (1994) the farming system can potentially affect exposure because pesticide deposited/sorbed from the atmosphere onto the pasture surface can be consumed by cattle from soil. The daily intake of soil by beef cattle is 180 kg/year from grazing fresh grass/silage or hay (Fries & Faustenbach, 1990), and/or feeding on harvested forage.…”

“…Farming system can potentially affect exposure because pesticide deposited from the atmosphere onto the pasture surface can be consumed by cattle eating fresh grass, silage or hay (Fries and Paustenbach 1990;Lorber et al 1994). In contrast, husks (which could potentially be contaminated) are removed from cereals fed directly to cattle kept indoors, although concentrate feed can be contaminated (Sharma et al 2005).…”

The aim of the present study was to assess the levels of organic pollutants in cattle from the NW of Spain. The livers of 101 animals from two regions (Galicia and Asturias) were analysed for seven organochlorine pesticides (HCB, alpha-HCCH, u-HCCH, HEOD, DDT, TDE) and 34 PCBs congeners (8, 18, 28, 29, 31, 52, 77, 101, 105, 114, 118, 123, 126, 128, 138, 141, 149, 153, 156, 157, 167, 169, 170, 171, 180, 183, 187, 189, 194, 199, 201, 205, 206 and 209). The influence of different factors (type of farm and proximity to industrial areas) on pesticide accumulation in cattle was also studied. Overall, the frequency of occurrence and concentrations of OC pesticides and PCBs was low in calves from both regions. HEOD was detected most frequently and was found in more than half of the calves from each region. PCBs 141 and 153 were the most frequently detected PCB congeners but typically occurred in less than 20% of animals. The exposure of calves to the more abundant contaminants differed significantly between the regions and may be related to past usage patterns. Differences between farms in terms of their livestock management did not have a significant effect on pesticide accumulation by calves. The liver concentrations in calves were below maximum residues levels (RMLs) for human intake and there is no indication of any risk from these contaminants through eating calf liver.

“…En effet, ces composés sont stables physiquement, chimiquement et biologiquement. Leur biodégradation est très faible (quelques enzymes microbiennes dans le sol ou au niveau cellulaire), les seules voies de disparition étant une photocatalyse en surface ou une dégradation par l'ozone [13][14][15]. Ces composés ont en général des périodes élevées de demi-vie dans le sol (10-20 ans pour la TCDD selon Fries [16]) et constituent dès lors un réservoir important.…”
