crude oil is enriched in polycyclic aromatic hydrocarbons (pahs). many pah analogs have proved to potentially damage dna. dna damage can be assessed using various biomarkers to find out the degree of genotoxicity of pollutants following in vitro exposure. in this research the comet assay and micronucleus (mn) test were used to detect dna damages and cytogenetic changes following crude oil expos...

The biochemical properties of carotenoids from 2 species of freshwater bivalve, namely, Unio douglasiae nipponensis and Anodonta lauta, and 2 species of freshwater snail, namely, Cipangopaludina chinensis laeta and Semisulcospira libertina, were investigated. Diatoxanthin and fucoxanthin were identified as major carotenoids in both bivalves. In contrast, lutein and zeaxanthin were found to be t...

Abstract The increasing growth of the bivalve‐culture industry necessitates a scientific assessment carrying capacity (CC) this aquaculture system, in order to ensure sustainability. Here, using marine plankton ecological model and food balance, bivalve CCs were estimated for zones Jiaozhou Bay (JZB), an important center China. results indicated that mainly depended on filtration rates, which t...
