Polychlorinated biphenyls in the Hudson River

Comparison of Two Freshwater Turtle Species as Monitors of Environmental Contamination

“…These fish were collected from the Hudson River in an area of known PCB contamjnatJ.on (Brown et al 1985). The ability of turtles to store high concentrations of,PCBs in their fat without apparent adverse effects makes this taxa extremely useful for the biological monitoring of PCBs in freshwater ecosystems.…”

O legado das bifenilas policloradas (PCBs)

“…Hudson e a partir de 1975 o fato foi encarado como um "sério problema ambiental" 42 . Entretanto já era tarde de mais e o rio estava comprometido, apresentando concentrações de PCBs muito acima das permitidas pela legislação na época.…”

Effects of four organic pollutants on the growth of natural marine bacterioplankton populations

“…Use of petroleum products and pesticides worldwide has resulted in large organic pollutant inputs to coastal waters (Huggett & Bender 1980, Connell 1982, Hoffman et al 1984, Brown et al 1985. Research findings over the past decade indicate that bacteria make a significant contribution to the marine planktonic food web through the recycling of dissolved organic matter and by serving as prey for heterotrophic protozoa (Hagstrom et al 1979, Williams 1981, Fenchel 1982, Fuhrman & Azam 1982, Ducklow 1983, Fuhrman & McManus 1984.…”
