An apple a day keeps the doctor away’. While it may be true that a balanced diet is a prerequisite for good health, how good is what we eat and drink every day? And is it actually possible to fulfil every customer desire with the vast array of foodstuffs on offer? BSE, dioxin in eggs, EHEC sprouts: in the light of repeated food safety crises, the issue of quality assurance as well as customer-oriented quality management has become of prime importance for the agri-food industry.
Although much effort is made to prevent risks arising from food, food-borne diseases are an ever present-threat to the consumers’ health. The consumption of fresh food that is contaminated with pathogens like fungi, viruses or bacteria can cause food poisoning that leads to severe health damages or even death. The outbreak of Shiga Toxin-producing enterohemorrhagic E. coli (EHEC) in Germany and neighbouring countries in 2011 has shown this dramatically. Nearly 4.000 people were reported of being affected and more than 50 people died during the so called EHEC-crisis. As a result the consumers’ trust in the safety of fruits and vegetables decreased sharply.

Chain models as a tool to quantify the relation between soil, crop quality and human exposure

Durch natürliche und anthropogene Säureeinträge sind vor
allem auf naturnahen Standorten Mineleuropas, insbeson-
dere bei Waldböden, schwerwiegende und langfristig wirk-
same negative Veränderungen der Bodeneigenschaften, der
Bodenvegetation und teilweise auch der Qualität des Si-
ckerwassers und der Oberflächengewässer eingetreten
(Veerhoff et al. 1996). Die weitere Bodenentwicklung auf
solchen Standorten wird ganz wesentlich von der SNK und
den H'-Pufferraten der (noch) vorhandenen Bodenminerale
bestimmt. Um Prognosen über die zukünftige Entwicklung
machen zu können, wurden neun für Böden typische Mine-
rale auf ihr Pufferverhalten untersucht.
Chloritesare found in igneous rocks, and more commonly
in sediments and low grade metamorphic rocks (BrinJiey &
Brown 1980). Because chlorites are less stable than most of
the other clay minerals when placed into an acidic
environment (Barnhisel & Bertsch 1989), they play
significant roles in the solution chemistry and may be an
important source of magnesium and micronutrients in soils
(Ross 1975). The objective of the present study was to
compare the weathering behavior of different chlorites in
different chemical environments.
