Nitrate was monitored in eighteen kinds of vegetables, nine kinds of fruit and in tap water.
A total of 1369 samples were taken over a period of one year and analysed using high performance liquid chromatography.
From the results it can be concluded that especially leafy vegetables can contain high levels of nitrate, and that the legally fixed maximum limits are fairly regularly exceeded.
The average nitrate content however does not exceed these limits.
The nitrate uptake through food consumption is evaluated by analysing some commodities after normal processing before consumption (washing, peeling, cooking, etc..). These treatments result in a significant reduction of the nitrate content.
Finally it was calculated that, according to the average content, the nitrate uptake through consumption of the investigated food package corresponds, on an annual basis, to 70. 13% of the acceptable daily intake (ADI).
