Harmonized Suspect and Non-Target Screening (NTS) Protocols Enhance Environmental Monitoring Efficiency
Category: Resource Management · Effect: Strong effect · Year: 2023
Standardizing suspect and non-target screening methodologies in environmental monitoring leads to more reliable data and better resource allocation for regulatory and risk assessment purposes.
Design Takeaway
Designers should focus on creating modular and adaptable analytical systems and software that can be readily integrated into harmonized NTS workflows, ensuring clear data reporting and quality assurance measures.
Why It Matters
Effective environmental monitoring is crucial for understanding the impact of chemicals on ecosystems and human health. By harmonizing NTS techniques, design practitioners can develop more robust and comparable analytical tools, reducing wasted effort and improving the accuracy of risk assessments, which in turn informs sustainable resource management decisions.
Key Finding
A collaborative effort has produced a guide to standardize suspect and non-target screening methods in environmental monitoring, covering the entire process from sample collection to data analysis, to ensure higher quality and more comparable results.
Key Findings
- Harmonization of NTS methods is needed for effective implementation and acceptance by stakeholders.
- Guidance is provided for all steps of NTS, including sampling, sample preparation, analysis (LC-HRMS/MS, GC-HRMS/MS, ion mobility), data evaluation, and reporting.
- While a standard operating process is not yet feasible due to rapid developments, recommendations for appropriate methods, data processing, and databases are offered.
- Quality assurance and confidence in identification assignment are critical components of NTS.
Research Evidence
Aim: How can standardized protocols for suspect and non-target screening improve the quality and comparability of environmental monitoring data?
Method: Guidance document development and expert consensus
Procedure: A working group of experts from the NORMAN Association compiled existing knowledge and best practices for suspect and non-target screening (NTS) in environmental monitoring. They developed a comprehensive guidance document covering all stages from sampling to data interpretation, aiming to harmonize approaches across different laboratories and applications.
Context: Environmental monitoring and chemical analysis
Design Principle
Standardization and interoperability in analytical methodologies enhance data reliability and resource efficiency.
How to Apply
When designing environmental monitoring equipment or software, consider modularity and data compatibility to align with emerging NTS harmonization efforts. Develop clear protocols for data quality assurance and confidence in identification.
Limitations
The rapid evolution of NTS techniques means that no single standard operating procedure can be universally applied at this stage. Different matrices and research questions may require tailored approaches.
