PCS concentrations in over-wintering birds collected in late February were three times higher than those in birds collected in November. PCB and petroleum concentrations remained at about the same level throughout the 3-month winter period. Petroleum hydrocarbons were present in all cormorants and residues in some individuals exceeded 25 ppm (wet weight). Mean DDE residues in samples collected in November and February were less than 1 ppm. Low concentrations of five other organochlorine compounds, not detected in cormorants collected in November, were recovered in birds collected in Februaryagricultural wastesASW,Galveston BaybioaccumulationchemicalscontaminantsD 04801 Pollution monitoring and detectionH SE1.21 WILDLIFEHydrocarbonsIndustrial wastesO 4020 POLLUTION - ORGANISMSoil pollutionP 6000 TOXICOLOGY AND HEALTHpesticidespetroleumPhalacrocorax auritusQ1 01504 Effects on organismsTexas,Galveston BayUSAUSA,TexaswinterX 24136 Environmental impactX 24156 Environmental impactJournal
