Notes
Like bioaccumulation and persistence, tocicity is an important criterion to determine the environmental impact of a substance. According to OSPAR criteria a substance should be considered toxic if
- exposure to marine concentrations below 1 mg/l of the substance can cause acute toxicity to marine organisms.
- long term exposure to marine concentrations below 0,1 mg/l can have an impact on marine organisms.
- or if the substance is carcinogenic or can cause endocrine disruptive effects to mammals. [1]
