ASci Corporation provides a wide range of laboratory testing services to clients worldwide. These services include aquatic toxicity and chemical fate testing for both complex effluents and single chemicals. ASci is also a leader in the performance of full spectrum acute and chronic Toxicity Identification Evaluations (TIEs). ASci's testing facility, displayed below, is located in Duluth, Minnesota, approximately 150 miles north of Minneapolis/St. Paul. The services provided by ASci's high tech laboratory include:
Aquatic Toxicology
Sediment Toxicology
Chemical Product Testing
Benthic Surveys
AQUATIC TOXICOLOGY
Effluent Testing
ASci is successfully assisting municipal and industrial dischargers to comply with increasingly stringent water quality regulations. Test programs provide dischargers with accurate, cost-effective biological and chemical testing and monitoring services.
ASci has conducted a broad spectrum of acute and chronic toxicity tests using freshwater and marine plants, fish, and invertebrate species and is experienced in addressing federal and state biomonitoring policies and procedures.
Toxicity Identification Evaluations
ASci has extensive experience in performing TIEs with both acutely and chronically toxic effluents and aqueous fractions in sediments. Several of our staff were instrumental in developing the TIE guidance documents currently in use throughout the U.S. This experience has given ASci a distinct advantage for performing full-scale TIEs resulting in toxicity remediation.
SEDIMENT TOXICOLOGY
Increasing concern over sediment toxicity demands the implementation of accurate assessment techniques. ASci has the expertise necessary to evaluate the toxicity of bulk sediments, elutriates, and pore waters.
Both static and flow-through test systems are utilized to assess sediment quality effects on the standard selected test organisms. Static and flow-through systems are constructed according to current scientific design and understanding.
TIE procedures routinely applied to identify classes of compounds responsible for sediment toxicity. These capabilities allow us to provide a well-rounded approach for addressing issues such as dredge spoils disposal and site remediation.
CHEMICAL PRODUCT TESTING
ASci offers comprehensive environmental testing services. These services include testing of chemical products and genetically engineered microorganisms for registration worldwide. ASci assists the pesticide, pharmaceutical, and biotechnology industries, as well as industrial chemical manufacturers, with environmental evaluations of their products.
ASci's laboratory testing facility maintains state-of-the-art equipment and conducts testing in compliance with Good Laboratory Practice (GLP) procedures. In addition to its full-service laboratory, ASci maintains a mobile laboratory unit for on-site analyses.
