Sulphur content was estimated in fruits and vegetables grown in Lower Silesia, such as apples, strawberries, cabbage, carrots, cucumbers and early potatoes. Based on the analysis of 2347 samples it is to be expected that with the present state of the natural environment about 5.7% of the crops of fruits and vegetables cultivated in this region will show excessive levels of sulphur. The limits of sulphur concentration were only slightly exceeded in the samples studied, which did not render the crops unfit for human consumption. However, their technological quality worsened making it difficult to store and process the products. Of the plants tested, cabbage followed by strawberries and cucumbers most often contained excess sulphur. Excessive amounts of sulphur in vegetables and fruits are more frequent in the Wrocław subregion than in other subregions of the Lower Silesia province.
