This study investigated the effect of temperature, turbulence, ultraviolet light, and carbon dioxide, on tire leachate particles and then studied the toxicological effects those solutions had on the fathead minnow (Pimephales promelas).
Five experiments were conducted where fathead minnow embryos were exposed to filtered leachates from tire particles or control water. Tires were leached for 10 days at varying temperatures, carbon dioxide (CO2) concentrations, turbulence, and ultraviolet-A (UVA) light conditions. All exposures were completed in 24-well plates containing 2 millilitres (mL) of solution per embryo, with 12 embryos per plate. Solutions were changed daily.
Observations such as hatching success, time to hatch, length, deformities, and heartbeat were measured on both embryos and the hatched fry.

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.
