Total mercury and methylmercury in fish from a tropical estuary
Mercury content, as methylmercury, in aquatic biota varies greatly among species from the same location. Many parameters may affect its accumulation and concentration in fish tissues. The study assessed total mercury (T-Hg) and methylmercury (MeHg) in the muscle, liver and gonad of Micropogonias furnieri carnivorous fish, Bagre spp. omnivorous fish and Mugil liza iliophagous fish from a pollute...
متن کاملPOPS IN MARINE MAMMALS: LEVELS AND EFFECTS PREDICTED BIOACCUMULATION OF PCBs AND TOXAPHENE IN BOTTLENOSE DOLPHINS (TURSIOPS TRUNCATUS): THE CONTRIBUTION OF CONTAMINATED PREY
Residues of two organochlorines (OCs) -Aroclor 1268 (a highly chlorinated PCB formulation) and toxaphene (a DDT-replacement pesticide) -are major persistent contaminants in St. Simons Sound near Brunswick, Georgia, USA. Although studies have recently documented OC levels in Brunswick area fish that are routinely consumed by humans, little is known about organochlorine body burdens in resident m...
متن کاملReproductive and transgenerational effects of methylmercury or Aroclor 1268 on Fundulus heteroclitus.
This research determined the potential for methylmercury or Aroclor 1268 to disrupt reproduction and sexual differentiation in Fundulus heteroclitus. The research determined whether fish that are exposed to mercury or Aroclor 1268 survive and successfully reproduce; whether offspring of exposed fish hatch, survive, produce eggs, and fertilize them; and whether the second-generation offspring of...
متن کاملChlorobornanes in Water, Sediment, and Fish from Toxaphene Treated and Untreated Lakes in Western Canada
Concentrations of toxaphene (CHB) and 2-exo,3-endo,5exo,6-endo,8,9,10-heptachlorobornane (B7-1001; Hp-Sed), a major toxaphene component known to be present in the sediment of toxaphene treated lakes, were determined in water, sediment, and fish from 13 lakes to examine the relationship between chlorobornane levels in fish and environmental variables. The lakes were situated in either the boreal...
