Introduction
GB/T 43419 "Heavy Metal Control in Rice Fields" is a technical standard to guide the control of heavy metals in rice fields: It aims to guide the management of heavy metals in rice fields:
Work process, through selecting appropriate treatment technologies, to achieve safe production in contaminated rice fields: GB/T 43419 is planned to consist of three parts:
---Part 1: General principles: The purpose is to provide general technical guidance for the entire process of heavy metal control in rice fields:
---Part 2: Passivation conditioning: The purpose is to select appropriate soil control methods for single and compound pollution of cadmium, mercury, arsenic, lead and chromium in rice fields:
Provide technical guidance on appropriate passivating conditioners:
---Part 3: Physiological barrier: The purpose is to provide technical guidance for selecting appropriate physiological barrier agents for heavy metal control in rice fields:
This document is Part 1 of GB/T 43419, which standardizes industry terminology, divides heavy metal control units in rice fields, categorizes management and treatment
Provide overall technical guidance for the entire process including management, project implementation and acceptance management to promote the improvement of soil quality in my country's heavy metal-contaminated rice fields and agricultural
The products are produced up to standard, achieving sustainable utilization of soil, and providing standardized support for the development of the environmental protection industry for heavy metal control in rice fields:
Heavy metal control in rice fields
Part 1: General Provisions
1 Scope
This document stipulates the basic principles, work procedures, preliminary preparations, division of treatment units, classified management and treatment methods of heavy metals in rice fields:
Project preparation, project implementation and acceptance management, etc:
This document is applicable to the classified treatment of rice fields contaminated by heavy metals such as cadmium, mercury, arsenic, lead and chromium:
This document does not apply to dry farming and the treatment of radioactive heavy metal contaminated rice fields:

3 Terms and definitions
The following terms and definitions apply to this document:
3:1
Adopt passivation conditioning, physiological barrier, agronomic regulation, alternative planting, planting structure adjustment, biochemical restoration and other measures to reduce soil heavy metals
It is a technical measure for biological effectiveness or total amount and heavy metal content of agricultural products:
3:2
investigation unit investigation unit
Rice field regional units are delineated according to hydrology, soil type, soil parent material, and terrain that are relatively consistent and within the same administrative division:
3:3
Rice field regional units are delineated according to the consistency of soil type, pollution causes, pollution types, and pollution levels:
3:4
passivation conditioningimmobilization
By applying passivation conditioners or assisting with water and fertilizer management and other measures, the physical, chemical and/or biological properties of the soil can be improved, and soil degradation can be reduced:
Heavy metal effectiveness technology:
3:5
physiological barrier physiological barrier
By applying physiological barrier agents, we can inhibit the absorption of heavy metals by crops or change the distribution characteristics of heavy metals in the plant, thereby reducing the edible value of agricultural products:
Heavy metal content of parts:
