EnviChem is a factual database containing test results data on ca. 3000 substances. EnviChem contains data related to the effects, fate and behaviour of chemicals in the environment. The most extensive part of the report is the toxicity data (LC/EC/IC50, LOEC, NOEC etc.) of substances to aquatic organisms. There are also data on physico-chemical properties, degradation, metabolism, bioaccumulation and the effects of the substance to terrestrial species eg. plants and mammals.
The content of EnviChem database is useful to environmental researchers, authorities, hazard assessors and companies dealing with chemicals. Correct interpretation of the core data requires some experience of environmental hazard assessment and chemistry.
The original aim of EnviChem has been to facilitate the environmental hazard and risk assessment and the environmental classification of chemical substances. EnviChem contains information related to general information, physico-chemical properties, degradation, metabolism, bioaccumulation and the effects of the chemical to terrestrial and aquatic environment. The most extensive part of the report is the toxicity to aquatic organisms.
The data concerning individual substances in EnviChem is divided into the following topics:
- General information
- Physico-chemical properties
- Information about degradation
- Information about metabolism and bioaccumulation
- Effects on terrestrial ecosystem
- Effects on aquatic ecosystem
A typical way of expressing acute lethal toxicity to fish is presented in the following way:
LC50 values to fishes, mg/l :
2.2 96 hr, Brachydanio rerio
0.9 96 hr, flow through, Pimephales promelas
2 96 hr, flow through, Pimephales promelas
0.46 96 hr, flow through, Ictalurus punctatus
0.9 96 hr, static, Lepomis macrochirus
0.35 96 hr, flow through, Perca flavescens
7.3 96 hr, static, Leuciscus idus

The list of Abbreviations and The list of Species are available at the EnviChem www SEARCH-page.
Each dataset is always related to a substance. CAS-numbers or substance names can be used as search keys.
The EnviChem database is maintained by Finnish Environment Institute (SYKE)
Box 140, Helsinki, 00251, Finland
The data in EnviChem has mainly been compiled from scientific publications, handbooks and databases in the field of ecotoxicology. The great majority of the content of EnviChem data has been stored to the data-base between the years 1985-2001. The scientific value of the compiled information has not regularly been assessed by the Finnish Environment Institute and the original published data may not have undergone any systematic peer-review process. The Finnish Environment Institute takes no responsibility for any faults/mistakes in the content of the database.
