AB The ecological status of Algeciras Bay (South-west Europe), highly influenced by anthropogenicactivities, was assessed by monitoring Zn, Cd, Pb, and Cu in water and sediment samples.Total contents and metal fractions with different availabilities and their spatial-seasonal distributionwere determined. The trend in water and sediment contents were Zn > Pb ≈ Cu > Cd, withoutsignificant seasonal variations. Sites 3 and 4, closest to industrial activities, had the highest metalconcentrations, mainly in sediments. Cd showed low partition coefficient in water, indicating higherbioavailability. Total metal content in sediments exceeded the threshold effect level for Cu and wereclose to Pb. The BCR procedure revealed the highest availabilities for Cd and Pb, due to its highercontent in exchangeable and reducible fractions. Higher Pb levels (21.4 ± 5.1 mg/kg) were foundin sediments of this bay compared with other ecosystems. Pollution indexes for sediment qualityrevealed that site 3 was the most polluted (CF = 7.12 and Igeo = 2.25). For an integrative study ofthe ecological status of this significant bay, these results have been complemented with the metalevaluation in benthic and benthopelagic fish tissues in Ecological status of Algeciras Bay, in a highlyanthropised area in south-west Europe, through metal assessment—Part II: Biotic samples.
