| hepatic metallothionein concentrations in the golden grey mullet (liza aurata) - relationship with environmental metal concentrations in a metal-contaminated coastal system in portugal. | this field survey was designed to assess the environmental metal contamination status of ria de aveiro (portugal). to achieve that goal, the concentrations of cd, hg, cu and zn in the sediments and water were assessed and liza aurata hepatic metallothionein (mt) determined. the relationships between mt and environmental metal concentrations and hydrological factors were examined. results revealed a wide distribution of metals both in water and sediments throughout the lagoon, mainly at rio novo ... | 2010 | 19913292 |
| monitoring pollution of coastal lagoon using liza aurata kidney oxidative stress and genetic endpoints: an integrated biomarker approach. | despite the importance of fish kidney in several functions (immune, metabolism and excretion of xenobiotics) its use in coastal water biomonitoring focusing on protection and damage is scarce. five critical sites in ria de aveiro (portugal; barra--bar, gafanha--gaf, rio novo do principe--rio; laranjo--lar and vagos--vag) were assessed in comparison to a reference site (torreira--tor), focusing on liza aurata kidney antioxidant defences versus damage responses. non protein thiols were higher at r ... | 2010 | 19916048 |
| antioxidant responses versus dna damage and lipid peroxidation in golden grey mullet liver: a field study at ria de aveiro (portugal). | the present work aimed to investigate golden grey mullet (liza aurata) liver protection versus damage responses at a polluted coastal lagoon, ria de aveiro (portugal), as a tool to evaluate the human impacts on environmental health at five critical sites in ria de aveiro (portugal) in comparison to a reference site (torreira; tor). protection was evaluated by measuring non-enzymatic [total glutathione (gsht) and non-protein thiols (npt)] and enzymatic [catalase (cat), glutathione peroxidase (gpx ... | 2010 | 20217061 |
