四川省主产稻谷、小麦。了解其铅的分布状况,可为制订粮食中铅含量的卫生标准提供科学依据,并为研究四川省土壤中铅的分布及土壤铅污染对植物的影响提供资料, 同时铅的本底现状,有助于今后考察四川省粮食中铅的消涨。为此,我们于1986年对四川稻谷和小麦中铅的含量进行了调查。 Sichuan Province, the main production of rice, wheat. Understanding the distribution of lead can provide a scientific basis for establishing the health standards for lead in food and provide information for studying the distribution of lead in soils of Sichuan Province and the impact of soil lead pollution on plants. At the same time, the current status of lead In the future, it will help to examine the decline of lead in grain in Sichuan Province. To this end, we investigated the lead content of rice and wheat in Sichuan Province in 1986.
