Adult trout Oncorhynchus mykiss fitted with a dorsal aortic catheter were exposed to 288+/-15 micromol l(-1) (mean +/- S.E.M.) total ammonia for 24h in water at a pH of 8.39+/-0.02, while swimming at a speed equivalent to 0.75 bodylengths s(-1) (BLs(-1)) in a Brett-type tunnel respirometer. The fish were then exposed to stepwise increments in swimming speed(More)
Complex physiological traits, such as routine aerobic metabolic rate or exercise performance, are indicators of the functional integrity of fish that can reveal sub-lethal toxicological effects of aquatic pollutants. These traits have proved valuable in laboratory investigations of the sub-lethal effects of heavy metals, ammonia and various xenobiotics. It(More)
Groups of eels (Anguilla anguilla) were exposed to Po river water under control conditions at "la Casella" Fluvial Hydrobiology Station for 30-day periods between November and May. At the end of the exposure period, fish were sacrificed and cytochrome P4501A was evaluated in liver microsomes using both catalytic (EROD) and semiquantitative immunodetection(More)
The Birmingham conurbation (West Midlands, UK) has traditionally been a major centre of UK industry and population and consequently has a legacy of pollution, which is reflected in the water quality of local rivers. Three of these rivers, exhibiting good, intermediate and poor overall water quality, were the subject of a study in which the effects of(More)
Trace heavy metal (Cd, Pb and Cu) and nitrogen species (N-NO3, N-NO2 and N-NH4) fluxes between sediment and water were examined for approximately 4 days, in a coastal marine station located in the northern Adriatic Sea in front of the River Po outflow. An in situ benthic chamber, equipped with electronic devices for monitoring and adjustment of oxygen and(More)
According to the European Directive 2008/50/CE, the air quality assessment consists in the measurement of the concentration fields, and the evaluation of the mean, number of exceedances, etc. of some chemical species dangerous to human health. The measurements provided by an air quality ground-based monitoring network are the main information source but the(More)
