美国《马铃薯杂志》一九七七年第四期报道,食物和水源中硝酸盐含量高,往往形成对人体健康的潜在危险。例如,硝酸盐是亚硝酸根的前体,而亚硝酸根同胺的一定阶段起反应,则形成致癌物质亚硝胺。为此,奥库斯亭等人研究了生长在不同类型土壤上,而且施肥不同、灌溉不同的马铃薯块茎的硝态氮含量。 According to the fourth issue of the “Potato Journal” in 1977, the high nitrate content in food and water sources often poses a potential danger to human health. For example, nitrates are precursors of nitrite, and nitrite reacts with certain stages of the amine to form the carcinogen nitrosamine. To this end, Okusiting et al. Studied the growth of different types of soil, but different fertilization, irrigation of different tuber of nitrate nitrogen content.
