•The BC coast has three distinct hydrocarbon source and sediment transport regimes.•Remote sediments have low petrogenic/pyrogenic input, with no anthropogenic input.•PAHs in sediments likely have low bioavailability on most of the coast.•Urban sediments show PAHs from vehicle emissions and fossil f...
