Bioassay data obtained using S. typhimurium strain YG+S9 showed PAH were a significant source of genotoxic contamination in Hamilton Harbour. We determined that PAH responsible for the observed YG+S9 activity in sediments and suspended sediments were primarily the 5- to 7-membered ring PAH with molecular masses between and amu, including the known mutagens and carcinogens benzo[a]pyrene, indeno Cited by: Hamilton Harbour CDF and Winona SL are known to be contaminated whereas Big Creek Marsh is a relatively clean, natural site.

Coun. Sam Merulla said he is still asking for a public health report on the issue, adding contamination of the harbour "is a concern for all Hamiltonians.". Laurel Sefton MacDowell writes in her book An Environmental History of Canada that, "As early as the s, a fishery inspector at Hamilton Harbour discovered that fish found along the shore tasted of coal oil and that dead ducks and muskrats were coated with oil from two refineries." By the s, city officials had deemed Hamilton Harbour unfit for any recreation use and shut down all beaches. Hamilton\'s industrial past has come at a price, namely, environmental degradation of surrounding ecosystems, in particular Hamilton Harbour. Prior to modern pollution laws, waste was dumped into the Harbour by industries, which today, continue to threaten public health, contaminate fish and wildlife, and restrict the use of the waterfront.

Sediment extracts from Hamilton Harbour had the highest concentrations of polychlorinated biphenyls and organochlorine insecticides (ppb) and contained very high concentrations of polynuclear aromatic hydrocarbons (ppm); although the levels of these compounds varied widely with sampling location in the harbor. Suspended sediment quality in Hamilton Harbour has been assessed as part of a long-term monitoring study (–). Sampling locations reflected a range of shoreline activities and sources of. Sediment from regions within Hamilton Harbour is highly contaminated with metals and polyaromatic hydrocarbons (PAHs); nevertheless, macroinvertebrates are present in situ and not all contaminated.
