Acute and physical effects of water-based drilling mud in the marine copepod Calanus finmarchicus
The aim of this study was to investigate impacts of fine particulate fraction of a commonly used barite-containing drilling mud on the pelagic filter feeding copepod Calanus finmarchicus . The results show that the tested drilling mud had a low acute toxicity on C. finmarchicus (LC50 > 320 mg/L)...
