The results of research on traditional medicine of china show the primary bioactivity of nitric oxide blood vessels and the ability to change nitrate to nitrite or nitric oxide .

对中国传统医学研究的结果显示了血管中一氧化氮的主要生物活性，也显示了把硝酸盐转变成亚硝酸盐或者一氧化氮的能力。

A study published earlier this year in the journal of food protection found that natural hot dogs had anywhere from one-half to 10 times the amount of nitrite that conventional hot dogs contained .

在今年早些时候在食物保护杂志上刊登的一篇研究指出半个天然热狗中所含的亚硝酸盐是一整条传统热狗中所含亚硝酸盐的十倍。

Consumers have also been repeatedly poisoned by excessive levels of the chemical nitrite in meat , feng ping , a professor at the beijing academy of food sciences , told an international food-safety conference last month .

消费者也一次次受肉制品中亚硝酸盐含量过高的毒害，冯平（音译），北京市食品科学研究院一名教授，在上个月的一次国际食品安全会议上说。

Objective to determine the nitrite content of unpacked salted vegetables marketed in xinxiang city .

结论新乡市市售的散装盐腌菜中亚硝酸盐含量基本合格。

The processing or curing of meats ( as with lunch meats and hot dogs ) is also a factor , since the procedure typically involves adding nitrate and nitrite substances chemical preservatives that were linked in this study to an increased cancer risk .

肉类的加工（如午餐肉、热狗）也是一大重要因素，这是因为加工的过程通常会加入硝酸盐和亚硝酸盐物质，这些化学防腐剂研究表明会增加得癌的风险。
