Operational discharges of produced water and drill cuttings from offshore oil and gas platforms are a
continuous source of contaminants to continental shelf ecosystems. This paper reviews recent research
on the biological effects of such discharges with focus on the Norwegian Continental Shelf. The greatest
concern is linked to effects of produced water. Alkylphenols (AP) and polyaromatic hydrocarbons (PAH)
from produced water accumulate in cod and blue mussel caged near outlets, but are rapidly metabolized
in cod. APs, naphtenic acids, and PAHs may disturb reproductive functions, and affect several chemical,
biochemical and genetic biomarkers. Toxic concentrations seem restricted to
