| We investigated the effect of 4 yr of aging of a noncalcareous soil contaminated with filter dust from a brass foundry (80% w/w ZnO, 15% w/w Cu0.6Zn0.4) on the chemical extractability of Zn and Cu and their uptake by barley (Hordeum vulgare L.), pea (Pisum sativum L.), and sunflower (Helianthus annus L.). Pot experiments were conducted with the freshly contaminated soil (2250 mg kg21 Zn; 503 mg kg21 Cu), with the contaminated soil aged for 4 yr in the field (1811 mg kg21 Zn; 385 mg kg21 Cu), and with the uncontaminated control soil (136 mg kg21 Zn; 32 mg kg21 Cu). In comparison with the uncontaminated soil, the growth of barley and pea was clearly reduced in both contaminated soils, while toxicity symptoms did not systematically vary from the freshly... |

| Organochlorine pesticides (OCP’s), such as dieldrin or DDT, were applied world wide against pests in horticulture, fruit and arable crops. Although OCP’s were banned 20 years ago, they still persist in soils and are taken up by the plants (Mandl and Lindner 1999). OCP residues in soil, for instance dieldrin, has been detected in high economic value crops (Wyss et al., 2004) such as cucumber and pumpkin (Cucurbitaceae), which strongly accumulate OCP in their fruits. Consumers generally expect that food is safe and uncontaminated, but those who buy organically grown products are particularly concerned about health and thus sensitive to food quality. Therefore, OCP residues in organic food stuff have become a major issue not only for food control authorities,... |

| Landwirtschaftliche Produktionsflächen können Rückstände von Pflanzenschutzmitteln aus der Gruppe der Organochlorpestizide (OCP) enthalten. Diese Gruppe von Spritzmitteln wurde bis vor ca. 30 Jahren in verschiedenen Bereichen der konventionellen Landwirtschaft zum Teil grossflächig eingesetzt. Wie das bekannte DDT gehört auch Dieldrin zu diesen OCPs. Obschon diese Pflanzenschutzmittel in der Schweiz heute nicht mehr angewendet werden dürfen, finden sich in manchen Böden Rückstände davon. Dies vor allem darum, weil sie im Boden kaum abgebaut werden. Leider sind auch in heute biologisch bewirtschafteten Parzellen solche Verbindungen vorhanden. Kürbisgewächse nehmen besonders gerne OCP auf, da sie in den Wurzeln ein spezielles Enzym besitzen, dass die... |
