Samples of fish, waterfowl and small mammals have been found to contain elevated levels of certain metals and other pollutants. In this study, water and stream-and lake-sediments were collected along the Pecos River during a five-day period in September 1992 and were analyzed for mercury, lead, copper and zinc. Sediments were also analyzed for chromium. Mercury, lead, copper and zinc concentrations in sediments are elevated above and immediately below the Pecos mine waste dumps, suggesting that the waste dumps, outcropping zones of mineralization and the outcropping rocks may be potential sources. However, elsewhere in the Pecos drainage basin other sources for these metals should be considered as well.","PeriodicalId":203655,"journal":{"name":"Carlsbad Region (New Mexico and West Texas)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130483947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
