ISO 18330 Pesticide and veterinary drug residue detection in herbsISO 18330 Pesticide and Veterinary Drug Residue Detection in Herbs Laboratory Testing Service Provided by Eurolab
ISO 18330 is an international standard that governs the testing of pesticide and veterinary drug residues in herbs. This standard is developed by the International Organization for Standardization (ISO) in collaboration with other standard development organizations, such as the European Committee for Standardization (CEN), the American Society for Testing and Materials (ASTM), and the Turkish Standards Institution (TSE).
Legal and Regulatory Framework
The testing of pesticide and veterinary drug residues in herbs is regulated by various laws and regulations worldwide. In the European Union, for example, the use of pesticides and veterinary drugs in agriculture is governed by Regulation (EC) No 396/2005 on maximum residue levels (MRLs). Similarly, in the United States, the Environmental Protection Agency (EPA) sets MRLs for pesticide residues in food.
International and National Standards
The following standards are relevant to ISO 18330:
Standard Development Organizations
Standard development organizations play a crucial role in developing and updating standards. The main standard development organizations involved in the development of ISO 18330 are:
How Standards Evolve and Get Updated
Standards evolve and get updated to reflect changes in technology, science, and regulatory requirements. The standard development process involves a series of steps:
1. Proposal: A proposal is submitted by an interested party to develop a new standard or update an existing one.
2. Drafting: A drafting group is formed to develop the draft standard.
3. Public Review: The draft standard is made available for public review and comment.
4. Voting: The comments received during public review are considered, and a final draft is developed for voting by member bodies of the standard development organization.
Standard Numbers and Scope
The following standard numbers and scope are relevant to ISO 18330:
Scope: This standard specifies a method for detecting pesticide and veterinary drug residues in herbs using gas chromatography with electron capture detection (GC-ECD).
Scope: This standard specifies a method for determining pesticide residues in plants and plant products using GC-ECD.
Standard Compliance Requirements
Compliance with standards is required by various industries, including:
Compliance with standards ensures that products meet regulatory requirements and are safe for consumption or use.
The following table summarizes the key points related to standard-related information:

Methodology for Detecting Pesticide and Veterinary Drug Residues
The ISO 18330 standard specifies a method for detecting pesticide and veterinary drug residues in herbs using gas chromatography with electron capture detection (GC-ECD). The following steps are involved in this method:
1. Sample Preparation: Herb samples are prepared by crushing, grinding, or milling to facilitate extraction of pesticide and veterinary drug residues.
2. Extraction: Pesticide and veterinary drug residues are extracted from the herb sample using a suitable solvent.
3. Cleanup: The extract is cleaned up using a sorbent material to remove impurities.
4. GC-ECD Analysis: The cleaned-up extract is analyzed using GC-ECD to detect pesticide and veterinary drug residues.
The following table summarizes the key points related to the methodology for detecting pesticide and veterinary drug residues:
Step Description
