【科技日报讯 记者马爱平】4月21日，一项重大科研成果在农业农村部环境保护科研监测所揭晓。该所重金属生态毒理与污染修复创新团队揭示了小麦籽粒中营养组分对镉铅生物可给性的影响，为减轻重金属污染对人体健康的威胁提供了新的解决方案。
据研究报告，科研人员发现小麦籽粒中的钙、镁、植酸和甲硫氨酸等关键营养成分，能够显著影响镉和铅的生物可给性。这些元素的存在可能降低人体对镉铅的吸收率，从而减少重金属通过食物链进入人体的风险。这一发现对于重金属污染农田的安全利用具有开创性意义，为农作物品种的选育打开了新的研究方向。
“我们的研究不仅揭示了营养组分在重金属生物地球化学循环中的作用，也为农田环境保护和食品安全提供了科学依据。”项目负责人表示，这一成果有望引导农业生产向更加环保、健康的方向发展，通过优化作物品种，降低农作物对重金属的积累，从而保障消费者的食品安全。
该研究的实施，标志着我国在重金属污染治理和农产品质量提升方面取得重要进展，对于提升我国农业可持续发展能力，保障国民健康具有深远影响。未来，科研团队将进一步探索这些营养组分如何具体作用于镉铅的生物可给性，以期开发出更有效的农田修复技术和安全农产品生产策略。

**News Title:** “Scientific Breakthrough: Wheat Nutrients Found to Reduce Risk of Cadmium and Lead Contamination, Ensuring Food Safety”
**Keywords:** Wheat contamination, Nutrient components, Heavy metal remediation
**News Content:**
**[From Science and Technology Daily – Reporter Ma Aiping]** On April 21, a major scientific achievement was announced at the Agricultural Environmental Protection Research and Monitoring Institute under the Ministry of Agriculture and Rural Affairs. The Innovative Team on Heavy Metal Ecotoxicology and Pollution Remediation revealed the impact of nutritional components in wheat grains on the bioavailability of cadmium and lead, offering a new solution to mitigate the health threats posed by heavy metal contamination.
According to the research report, scientists discovered that key nutritional components in wheat grains, such as calcium, magnesium, phytic acid, and methionine, significantly influence the bioavailability of these toxic metals. The presence of these elements may decrease the human body’s absorption rate of cadmium and lead, thereby reducing the risk of heavy metals entering the human body through the food chain. This finding holds groundbreaking significance for the safe utilization of contaminated farmland and opens new avenues for crop variety selection.
“The study not only uncovers the role of nutrient components in the biogeochemical cycle of heavy metals but also provides scientific evidence for agricultural environmental protection and food safety,” said the project leader. This achievement is expected to steer agriculture towards a more environmentally friendly and healthier direction, by optimizing crop varieties to lower heavy metal accumulation and, in turn, safeguard consumers’ food safety.
This research signifies a significant advancement in China’s efforts to address heavy metal pollution and enhance agricultural product quality. It has far-reaching implications for promoting the sustainability of Chinese agriculture and ensuring national health. In the future, the research team aims to delve deeper into how these nutrient components precisely affect the bioavailability of cadmium and lead, with the goal of developing more effective农田 remediation techniques and strategies for producing safer agricultural products.
