ECOTOX LIMITATIONS

You should review the limitations of ECOTOX data retrieval and system requirements prior to performing searches on this site.

Disclaimer

You should consult the original scientific paper to ensure an understanding of the context of the data retrieved from the ECOTOX database.

ECOTOX attempts to be comprehensive, our searches do not locate all relevant literature. In addition, the time lag from conducting a literature search, acquiring the publication and encoding it into the ECOTOX database can be up to or exceed six months. For this reason, we also suggest that you conduct searches of the most recent publication year to ensure you capture data that has not been entered into the ECOTOX database.
