Screening of Practical Low-accumulating Crops in Cadmium-polluted Farmland: A Field Survey and Field Trail in Guangdong Province, China
Cadmium (Cd) contamination in soil poses significant threats to human health through the food chain. An effective and eco-friendly solution is to cultivate crops that absorb less Cd in their edible parts, referred to as low-accumulating crops (LACs). This approach is particularly beneficial in areas with limited arable land. However, research on practical LACs is still limited. To address this, a field survey and trial were conducted in Cd-contaminated farmlands in Guangdong Province, China. The survey assessed 41 crops, revealing that 83.4% of the samples met safety standards, with an average limit-exceeding risk (ERC-Cd) of 0.731. Based on the compliance status, 13 crops were selected for field trials on heavily polluted farmland to evaluate their stability. The compliance rate for these experimental crops reached 96.6%, with an average ERC-Cd of 0.483. Ultimately, 12 crops exhibiting high safety levels, stability, and potential for promotion were recommended as LACs. Throughout the field survey and trial, the identified LACs demonstrated high compliance rates (≥ 90.3%), stability across multiple seasons and locations, and potential adaptability to local environments and market demands. Thus, this study contributes to mitigating the contamination risk of agricultural products in Cd-contaminated farmlands of Guangdong. Furthermore, it facilitates the application and dissemination of alternative cultivation techniques by providing an effective method for screening practical LACs in specific regions.
期刊介绍:
The Journal of Cleaner Production is an international, transdisciplinary journal that addresses and discusses theoretical and practical Cleaner Production, Environmental, and Sustainability issues. It aims to help societies become more sustainable by focusing on the concept of 'Cleaner Production', which aims at preventing waste production and increasing efficiencies in energy, water, resources, and human capital use. The journal serves as a platform for corporations, governments, education institutions, regions, and societies to engage in discussions and research related to Cleaner Production, environmental, and sustainability practices.
