As part of an ongoing assessment of the long-term impacts of oil and dispersants on ecosystem health experiments were performed to examine the effects of exposure on different species of fish and varying routes of exposure. As a part of this study we directly assessed the mutagenic potential of the contaminated treatments as well as the surrounding environment in which the fish were contained. For these assessments we used the biologically based assay of DNA damage termed the Microscreen Assay. General microbiological parameters including total viral and bacterial counts and culturable bacterial counts were also measured. Fish experiment data are available in GRIIDC datasets R4.x267.000:0040 and R4.x267.000:0041.
To directly measure the mutagenic potential of the oil contaminated treatments utilized in fish exposure experiments. Additionally, the mutagenicity of the surrounding media was assessed to ensure the exposures were contained within the desired treatment milieu. For example, when the oil exposure was contaminated the surrounding water was assessed for mutagenicity to ensure the oil didn’t significantly leach out of the food. Similar assessments were performed for water column and sediment exposures. Basic microbiologic parameters were also be measured to ensure comparable environments between treatment and control exposures.
