Why Choose BS EN ISO 17512-1:2020?

This standard is indispensable for those who are committed to maintaining and improving soil quality. It provides a scientifically validated method for assessing the impact of chemicals on soil organisms, which is critical for environmental monitoring and regulatory compliance. By using earthworms, which are sensitive indicators of soil health, this standard ensures that the tests are both reliable and relevant.

Benefits of Using This Standard

• Comprehensive Guidance: Offers detailed instructions on conducting avoidance tests, ensuring consistency and accuracy in results.
• Environmental Protection: Helps in identifying harmful chemicals and their effects on soil ecosystems, promoting sustainable environmental practices.
• Regulatory Compliance: Assists organizations in meeting environmental regulations and standards, reducing the risk of non-compliance penalties.
• Scientific Rigor: Based on the latest scientific research, providing a robust framework for soil quality assessment.

Applications

The BS EN ISO 17512-1:2020 standard is applicable in various fields, including:

• Environmental Monitoring: Used by environmental agencies and organizations to monitor soil quality and detect chemical contamination.
• Agriculture: Helps farmers and agricultural professionals assess soil health and the impact of agricultural chemicals.
• Research and Development: Utilized by researchers in developing new methods for soil quality assessment and environmental protection.
• Industrial Compliance: Assists industries in evaluating the environmental impact of their operations and ensuring compliance with environmental standards.

Understanding the Test Method

The avoidance test described in this standard involves exposing earthworms to soil samples with and without chemical contaminants. The behavior of the earthworms, specifically their avoidance of contaminated soil, is observed and recorded. This test is a powerful tool for assessing the ecological impact of chemicals, as earthworms are highly sensitive to changes in soil quality.

Earthworms as Bioindicators

Earthworms, particularly Eisenia fetida and Eisenia andrei, are excellent bioindicators due to their sensitivity to soil pollutants. Their behavior provides valuable insights into the health of soil ecosystems, making them ideal subjects for avoidance tests. This standard leverages their natural behavior to provide accurate assessments of soil quality.

Conclusion

The BS EN ISO 17512-1:2020 is an essential resource for anyone involved in soil quality assessment and environmental protection. By providing a standardized method for conducting avoidance tests with earthworms, it ensures that soil quality assessments are accurate, reliable, and scientifically sound. Whether you are an environmental scientist, an agricultural professional, or an industry leader, this standard is a valuable tool for promoting sustainable practices and protecting our natural resources.

BS EN ISO 17512-1:2020

This standard BS EN ISO 17512-1:2020 Soil quality. Avoidance test for determining the quality of soils and effects of chemicals on behaviour is classified in these ICS categories:

• 13.080.30 Biological properties of soils

This part of ISO 17512 specifies a rapid screening method for evaluating the habitat function of soils and the influence of contaminants and chemicals on earthworm behaviour.

The sublethal test is a rapid method that reflects the bioavailability of contaminant mixtures in natural soils and substances spiked into soils to Eisenia fetida and Eisenia andrei. The avoidance behaviour of the worms is the measurement endpoint of the test. This test is not intended to replace the earthworm reproduction test.

Two different designs (a two section unit and a six section unit) have been developed and successfully applied. Both designs are applicable to either single-concentration (e.g. for assessing the quality of a field soil) or multi-concentration (e.g. for assessing the toxicity of a spiked chemical) tests. In both cases, the earthworms are allowed to make the initial choice on which compartment, control and a treatment [in the two section test vessel between right and left side; in the six section test vessel between the (3 + 3) alternating compartments], to enter.
