Tetraploid yeast cells (Saccharomyces cerevisiae) were used in the comet assay with the intention of developing a new, fast and easy assay for detecting environmental genotoxic agents without using higher organisms. Two DNA-damaging chemicals, H 2 O 2 and acrylamide, together with wastewater from three municipal treatment plants were tested for their effect on the yeast-cell DNA. The...
Damage to DNA detected by use of the single-cell gel electrophoresis (comet) assay was monitored in blue mussels, Mytilus edulis, sampled from coastal waters in Denmark. Mussels from five locations in Køge Bay, an area receiving wastewater from many industries and municipalities, were collected five times during 1999 and six times in 2001. In 1999, both gill cells and haemolymph cells were examined,...
Gill cells and hemocytes from the blue mussel Mytilus edulis were examined for DNA damage using the comet assay after laboratory exposure in vitro and in vivo to methyl methansulfonate (MMS). Hydrogen peroxide and UV radiation were used as positive control. Comet assay was also carried out on hemocytes from blue mussels sampled at polluted and unpolluted coastal areas. After 60min in vitro exposure...
