摘要:

通过三个硝酸盐的小故事,以一连串故事性的手法讲述硝酸盐在现今社会的主要用途,包括农业肥料、工业用炸药及食品防腐剂。社会将致癌的矛头指向硝酸盐,但硝酸盐不论在生态环境中还是人体内都扮演着重要的角色。本文讲述一对农村夫妻偶然地发现硝酸盐分别对种植、防腐、免疫及血液循环系统有益,发掘出硝酸盐更多的用途。

关键词: 硝酸盐, 农业肥料, 防腐, 免疫系统, 血液循环系统

Abstract:

Through three stories about nitrates, a storytelling technique is used to describe the main uses of nitrates today, including agricultural fertilizers, industrial explosives, and food preservatives. Nowadays, nitrate is suspected to be the main cause of carcinogenesis, but one coin has two sides; in fact, nitrates play an important role both in the ecological environment and in the human body. Therefore, the public can understand more about the applications of nitrates from this article. Through the accidental discovery of a rural couple in a wartime setting, this article describes the uses of nitrate in agriculture, antiseptic, immune systems and blood circulation system.

Key words: Nitrate, Agricultural fertilizer, Antiseptic, Immune system, Blood circulation system
