Ocratoxina A en plasma humano: nuevos datos de exposición en España

Ochratoxin A in human plasma: new data of expo- sition in Spain. In order to study the occurrence of Ochratoxin A in a southern region ofSpain, Granada, 83 blood plasma sam- ples collected from women have been analysed. The method of analysis is based on a liquid-liquid extraction followed by a High Performance Liquid Cromatographic (HPLC) analysis with fluorescence detection. The method has been validated and a detection limit of 0.21 ng/mL has been obtained. Ochratoxin A has been detected in 72% of the samples. The mean value was 0.63 ng/mL, with a standard deviation of 0.41 ng/mL and a range of concentrations from 0.11 ng/mL to 6.96 ng/mL. These results are similar to those found in other northern and medium regions of Spain, and to those found in the surroun- ding countries. Statistical analysis by Kruskal-Wallis (/? = 70;
