Samples of Hungarian and Indian soils (heavy and light) from different agro-ecological zones were taken in 1998 and 2002, respectively, and the periodic extractability of DTPA-extractable (plant available form) of Cd was determined after incubation at field capacity with different loads of Cd (10, 20, 40 and 80 mg Cd kg −1 soil) and correlated with some important soil properties. DTPA-Cd was found to be most highly correlated with cation exchange capacity (CEC), followed by organic matter (O.M.) and pH of the soils. A lower amount of added Cd was recovered in the form of DTPA-Cd with an increase in the time interval.

Kinetics of ochratoxin A production was examined in a number of ochratoxin producing isolates representing different sections of the Aspergillus genus. Both weak and high ochratoxin producers were tested using immunochemical or high-performance liquid chromatograhic methods. All isolates were found to produce the highest amounts of ochratoxin A after 7-10 days of incubation. Ochratoxin production varied between 30 - 5×105 ng ml-1 among the Aspergillus isolates tested. The A. albertensis and A. melleus isolates examined were found to produce ochratoxin A constitutively. A. albertensis produced the highest amounts of ochratoxin A at 30 °C after 7 days' incubation in YES liquid medium. Ergosterol content and ochratoxin production of A. albertensis cultures were in good correlation.

Kinetics of fungal spread and Trichothecenes B (TCT B) contamination were achieved using four hybrids of Maize characterized by different levels of resistance. Inoculation was performed using a toxigenic Fusarium graminearum strain 5 days after flowering into the silk channel. In addition, phenolic acids composition was evaluated at the different grain filling stages for the four hybrids. Results are discussed with regards to a potential involvement of phenolic acids in limitation of toxins accumulation and resistance level.

The absorption, distribution and elimination of fumonisin B 1 (FB 1 ) and its metabolites was investigated in pigs. For the determination of the absorption and biotransformation of FB 1 , T-cannula were implanted into the distal part of experimental pigs’ ileum and the total urine and faeces moiety was collected during the toxin feeding (45 mg FB 1 /kg diet, duration: 10 days) and in the subsequent elimination period (10 days). At the end of trial several organs, muscle and fat samples were also collected. The accumulative absorption of fumonisin B 1 was 4%. In the chymus, the FB 1 conversion to aminopentol (totally hydrolysed FB 1 ; AP 1 ) and partially hydrolysed FB 1 (PHFB 1 ) was 1% and 3.9%, respectively. Derivatives of FB 1 were mostly accumulated in the liver and kidney, while in negligible concentration could be detected in the muscle and fat samples. In the organs the efficacy of the FB 1 to AP 1 and PHFB 1 conversion was 30% and 20%, respectively. In the faecal content the main hydrolised product was PHFB 1 (47%), with 12% of AP 1 . 1.5% of the FB 1 quantity taken up was excreted with the urine, about 35% in hydrolyzed form. Detectable amounts of FB 1 and its metabolites were measured in most of the organs, in faeces and urine even 10 days after the feeding of the noncontaminated diet. As a general conclusion, the intestinal microbiota of pigs is able to transform the intact FB 1 to a similarly toxic substance (partially hydrolyzed FB 1 ) or to a more toxic metabolite (aminopentol).
