The toxicity of three alkylbenzene sulfonate (ABS) surfactants was assessed in 96-hour acute toxicity tests using freshwater algae, Chlamydomonas reinhardtii. Detection events were analysed using flow cytometry and enumerated at the beginning and end of the test.
All data are subject of a publication containing method details, full QA/QC, interpretations and conclusions. Citation: Hanana, H., Gilroy, È. A. M., Bartlett, A. J., Bennett, C. J., Brinovcar, C.

Supplemental Information
The Chemicals Management Plan (CMP) is a Government of Canada initiative aimed at reducing the risks posed by chemicals to Canadians and their environment. A key element of the Chemicals Management Plan is the monitoring and surveillance of levels of harmful chemicals in Canadians and their environment. Monitoring and surveillance are essential to identify and track exposure to hazards in the environment and associated health implications. Monitoring and surveillance programs provide the basis for making sound and effective public health and environmental health policies and interventions, as well as measuring the efficacy of control measures.
In support of the Chemicals Management Plan, monitoring and surveillance initiatives were established to support Health Canada and Environment and Climate Change Canada scientists, in collaboration with external partners and researchers, to advance our knowledge. This initiative has allowed the Government of Canada to increase its commitment to a number of existing monitoring initiatives, as well as to support new efforts.
