Change in the Concentration of Heavy Metals in Mushrooms for Their Preservation

Abstract

The article presents the results of studies on the concentration of heavy metals in edible mushrooms (Suillus luteus (Lat.), Lactarius deliciosus (Lat.), Armillaria mellea (Lat.), harvested in the conditions of the SE "Vinnytsia Forestry", and the hazard ratio of these toxicants for the human body is determined. The purpose of the research was to study changes in the concentration of heavy metals (lead, cadmium, zinc, copper) in mushrooms during their preservation in marinade. A comparative assessment of the concentration of lead, cadmium, zinc, and copper in fresh and preserved in marinade was carried out. Changes in the concentration of lead, cadmium, zinc, and copper in mushrooms and their hazard ratio during their preservation in marinade are shown. A different intensity of accumulation of heavy metals was revealed by the mushrooms Suillus luteus (Lat.), Lactarius deliciosus (Lat.) and Armillaria mellea (Lat.), collected in the conditions of the studied forest area. It was established that the highest content of lead and cadmium was found in Suillus luteus (Lat.), and zinc and copper in Lactarius deliciosus (Lat.). A lower concentration of lead by 1.14 times, 1.29 and 1.08 times, cadmium – by 1.62 times, 1.68 and 1.4 times, zinc was found in Suillus luteus (Lat.) - 1.2 times, 1.4 and 1.1 times, copper - 1.3 times, 2.2 and 1.8 times, compared to mushrooms before their processing and canning. Similar changes were found in the hazard ratio of lead, cadmium, zinc and copper in mushrooms preserved in marinade. In particular, the hazard ratio of lead, cadmium, zinc, and copper was lower in Suillus luteus (Lat.) by 1.55 times, 1.62, 1.25, and 2.1 times; Lactarius deliciosus (Lat.) - 1.29 times, 1.68, 1.43 and 2.9 times; Armillaria mellea (Lat.) - 1.08 times, 1.4, 1.17 and 1.88 times, respectively, compared to fresh mushrooms.

“…The longest back muscle of pigs exceeded the maximum permissible concentration by 8 times (Razanov & Voitko, 2017). Other studies found that upon fattening steers for meat within the territory belonging to Zone III of radioactive contamination, the accumulation of Pb in muscle tissue did not exceed regulatory requirements and amounted to 0.067-0.112 mg/kg, while the concentration of Cd was much higher than sanitary and hygienic requirements .…”
