title: [The amount of nitrites in edible mushrooms harvested from Bistriţa Valley].
abstract: In our study has been determined the amount of nitrites in edible mushrooms which grown in different zones from Bistriţa Valley, near to the "Fibrex-nylon" Complex Savinesti. The nitrites has been extracted with water, in the aqueous extract we determined spectrophotometrically nitrites with Griesz Reagent. The results were expressed in mg nitrites/g dried product (105 degrees C). We analysed 41 samples of edible mushrooms (22 samples harvested on october 2001, 19 harvested on september 2002). The nitrites concentrations in mushrooms are between 2.06 and 49.88 (samples harvested on october 2001), between 1.98 and 31.84 (samples harvested on september 2002). The highest values for samples harvested on october 2001 was determined in Laccaria lacata, Collybia butiracea, Hygrophorus chrysodon, Russula nigricans, for the samples harvested on september 2002 the highest values was determined in Boletus granulatus, Macrolepiota procera.
