Effects of chronic crude oil exposure on early developmental stages of the Northern krill ( Meganyctiphanes norvegica )
Rising oil and gas activities in northern high latitudes have led to an increased risk of petroleum pollution in these ecosystems. Further, seasonal high UV radiation at high latitudes may elevate photo-enhanced toxicity of petroleum pollution to marine organisms. Zooplanktons are a key ecological c...

Rising oil and gas activities in northern high latitudes have led to an increased risk of petroleum pollution in these ecosystems.
