Overview

This study investigated the bioavailability of lanthanum (La) from Phoslock, a La-modified bentonite clay used to mitigate eutrophication in lakes. The findings suggest that La from Phoslock is bioavailable to marbled crayfishes, advocating for careful consideration of potential side effects when using this product.

Original Abstract of the Article :
To mitigate eutrophication in fresh standing waters the focus is on phosphorus (P) control, i.e. on P inflows to a lake as well as a lake's sediment as internal P source. The in-lake application of the lanthanum (La) modified clays - i.e. La modified bentonite (Phoslock) or La modified kaolinite, ai...See full text at original site

Lanthanum Bioavailability in Crayfish: A Potential Environmental Concern

Eutrophication, the excessive enrichment of water bodies with nutrients, is a significant environmental problem. This study, published in Environmental Science & Technology, investigated the bioavailability of lanthanum (La), a metal used in modified clays for eutrophication control, to marbled crayfish (Procambarus fallax f. virginalis).

Lanthanum Accumulates in Crayfish

The study found that La from a modified clay used in eutrophication control was bioavailable and accumulated in various tissues of the marbled crayfish. This raises concerns about potential ecological impacts of using La-modified clays for eutrophication control.

Understanding Environmental Impacts of Water Treatments

This study emphasizes the importance of considering the potential environmental impacts of using chemicals for water treatment. It highlights the need for thorough assessments of the bioavailability and bioaccumulation of chemicals used in such applications.

Dr.Camel's Conclusion

Protecting our freshwater ecosystems is like safeguarding a precious oasis in the desert. This study raises concerns about the potential impact of La-modified clays on aquatic life. It reminds us that careful consideration of environmental consequences is crucial when implementing water treatment strategies. Just as a camel needs a clean water source, aquatic organisms need healthy environments to thrive.
