Transfer of benzo[a]pyrene and 2,2',5,5'-tetrachlorobiphenyl from bacteria and algae to sediment-associated freshwater invertebrates

Article Abstract:

The transfer routes of [3H]benzo[a]pyrene (BaP) and 2,2',5,5'[14C]tetrachlorobiphynol (PCB-52) from microrganisms found in freshwater sediments to oligochaetes (Lumbriculus variegatus} and chironomid larvae were studied in this experiment. The study is broken down into an introduction, a discussion of the materials and methods used, and a discussion of the results. Various graphs and tables accompany the article.

Biodegradation Residual of 4-Octylphenoxyacetic Acid in Laboratory Columns under Groundwater Recharge Conditions

Article Abstract:

Researchers simulated environmental conditions related to artificially replenishing groundwater supplies with treated wastewater to determine the biodegradability of 4-octylphenoxyactic acid. Tables, and figures accompany the article.
