The impact of microbial degradation of oil spills on toxicity to early life stages of marine fish
Effects of produced water components on early life stages of cold-water marine fish
Impacts of mine tailings on early life stages of cod and haddock
Effects of CaCO3 mine tailings on the marine copepod Calanus finmarchicus
Embryonic crude oil exposure impairs growth and lipid allocation in a keystone Arctic forage fish
Developmental effects in fish embryos exposed to oil dispersions – the impact of crude oil micro-droplets
During accidental crude oil spills and permitted discharges of produced water into the marine environment, a large fraction of naturally occurring oil components will be contained in micron-sized oil droplets. Toxicity is assumed to be associated with the dissolved fraction of oil components, howeve...
Embryonic exposure to produced water can cause cardiac toxicity and deformations in Atlantic cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) larvae
Regular discharges of produced water from the oil and gas industry represents the largest direct discharge of effluent into the marine environment worldwide. Organic compound classes typically reported in produced water include saturated hydrocarbons, monoaromatic and polyaromatic hydrocarbons (MAHs...
Acute and sub-lethal effects of an anionic polyacrylamide on sensitive early life stages of Atlantic cod (Gadus morhua)
Despite the possible increase in use of anionic polyacrylamide (APAM) in enhanced oil recovery operations, very little relevant information regarding ecotoxicity exists. The current study assessed acute and sub-lethal toxicity in sensitive early life stages (ELS) of Atlantic cod (Gadus morhua) expos...
Modeling the toxicity of dissolved crude oil exposures to characterize the sensitivity of cod (Gadus morhua) larvae and role of individual and unresolved hydrocarbons
Toxicity of weathered oil was investigated using Atlantic cod (Gadus morhua) larvae. A novel exposure system was applied to differentiate effects associated with dissolved and droplet oil with and without dispersant. After a 4-day exposure and subsequent 4-day recovery period, survival and growth we...
