The estimated ultimate LC50 values (LC50∞) were 279, 334, and 358 mg L-1 for Ce, Gd, and La, respectively. When expressed as body concentration, the LC50inter value was almost constant with time, demonstrating that internal body concentration could be a better indicator of dynamic toxicity of REEs than external dose. This study highlights that specific REE and exposure time should be taken into account in accurately assessing risk of REEs. The arsenic concentration is an important issue in compost production. The main inputs o
