Ecological assessment of nitrate content in plant products
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 101, Issue
Abstract
The article deals with the ecological assessment of nitrate content in plant products. The studies have been carried out by the express method with a nitrate tester in plant products of high demand among residents of the city of Kherson in all the seasons of the year. Sampling was conducted from October to April, and the seasonal dynamics of nitrate were investigated. The actual data were compared to the MPC (maximum permissible concentration) with the instrument. It was determined that in autumn almost all plant products comply with the hygiene requirements, except for several samples of onions and pears. Investigated samples of onions with a high nitrate level were observed for each season of the year, the nitrate fraction was 22.67 – 100%. In spring, the nitrate level is higher than in autumn: it indicates a high nitrate level in greenhouse products, and the use of mineral fertilizers with nitrogen in large quantities for its cultivation. The maximum level of nitrate during the study period is 908.79 mg/kg – 599.27 mg/kg. The obtained results offer an opportunity to inform the population about the presence of nitrates in plant products.
