Ecotoxicology
With over 20 years experience, the laboratories at Opus Plus are equipped to offer a comprehensive range of aquatic toxicity tests using experienced and committed personnel.
The Ecotoxicology Laboratory provides the full range of marine aquatic toxicity, biodegradation and bioaccumulation studies required by the Harmonised Mandatory Control System (HMCS).
The recent addition of our freshwater facility augments our long-established marine toxicity and biodegradation laboratory, which is linked to a shellfish hatchery and mariculture research unit. All work is carried out under Good Laboratory Practice (GLP), following OSPARCOM, OECD, ISO and ASTM (USA) guidelines.
