Toxicity test method

Suspension preparation method
1000 mg/L black carbon stock suspension was made by sonicating 400 mg black carbon powder in 400 mL 0.05% SDS solution. The mixture was sonicated in an ice bath with a sonicating probe (Vibra-Cell VCX 500, Sonics & Material, Newtown, CT) at 100 W for 30 min. The sample was stored at room temperature in a 500 mL clear glass bottle wrapped in aluminum foil before use within 6 months.

Particle size measurement method

ENM electrophoretic mobility measurement.
