Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard technical content and Organisation for Economic Co-operation and Development (OECD) guidelines for testing of chemicals No.307 (2002 Nian) "good soil Aerobic and anaerobic conversion of the "same (in English) of technical content.

This standard configuration and do the following editorial changes.

--- The units of measurement to our legal units of measurement.

--- Consistent with the existing standard series, the standard name will be changed to "chemical products in the soil Aerobic and Anaerobic transformation test."

--- Remove OECDNo.307 (2002 Nian) "soil aerobic and anaerobic conversion" Introduction of an information section.

--- The original "test substance" section on the physical and chemical properties are given five reference test methods. Six of nine tested party Indexes Our law has a corresponding standard.

Introduction

This test method is used to evaluate aerobic and anaerobic transformation of chemicals in soil. This test is used to determine (i) conversion of the test substance Rate, and (i) determining the nature of the plant and may be exposed to soil microbial conversion products and their production rate and degradation rate. The test Test test subjects who applied directly to the soil or is likely to enter the soil environment of chemicals. Such laboratory results Provides sampling and analysis program for the study of related fields.

Evaluation of the test substance conversion pathway only use a soil aerobic and anaerobic transformation of research, and the conversion of the test substance should be used Three or more to other soil Determination.

Soil type test shall be representative of the test substance use and release into the environment conditions. For example, may be released into the soil subtropical, tropical Chemicals is appropriate Ferrasols or Nitosols way to handle (FAO system). This method can also be used in paddy soil.

CHEMICALS Aerobic and Anaerobic Transformation in Soil Test

1 Scope

This standard specifies the terms and definitions of chemical products in the soil Aerobic and Anaerobic transformation test, the test substance information, test principle, reference material, again Overview of test methods, test procedures, quality assurance and quality control, data and reports.

The standard for evaluating aerobic and anaerobic transformation of chemicals in soil; for the determination of chemical substances in plants and soil for the nature and production rate conversion rate used under, and transformation products, degradation rate [1-9].

This standard applies to low-volatile, water-soluble or water-soluble, it can be accurately measured all chemicals (including radioactive marker or marker).

This standard does not apply to have volatile in the soil and the chemical substances under the experimental conditions can not be retained in the soil.
