While it is being used as such, the sediment quality guideline ERL (effects range low) is not a threshold of any chemical concentration in sediment at which the probability of toxicity shows an abrupt increase. Similarly, while it has been done, there is no basis for assuming that multiple concentrations above an ERL increase the probability of toxicity.
当沉积物质量准则效应范围低值（ERL）被如此使用时，它并不是沉积物中任何化学物质浓度的阈值，在该阈值处毒性发生概率会突然增加。同样，虽然已经这样做了，但没有依据假定超过ERL的多个浓度会增加毒性发生概率。
