The ammonia concentration measured in Hamilton Harbour, Ontario, Canada was typically 0.1-3 mg/L (100-3,000 ppb) in the early 1980s. This body of water is used for water transport, as a source for industrial cooling water, and as a receptor for waste water disposal (Snodgrass and Ng 1985). Measurements made a few years later (1987-1988), in contrast, showed much lower concentrations. Measured concentrations, however, were still greater than the International Joint Commission objective of 20 pg/L for more than half the year, and concentrations often exceeded the chronic toxicity threshold of 300 pg/L (Barica 1990). This work reported that ammonia loadings into Hamilton Harbor had decreased over the late 1970 s and 1980 s, and the measured concentrations may reflect that change.

Hard coal product has increased from less than 1 billion ton to almost 5 million ton from 1900 to 2005 [1]. Due to coal mining, coal industry, atmospheric transport, runoff, and flooding etc, unbumt coal and coal-derived partieles ean be wild spread in the aquatic system, and consequently settled in sediments. For example, imbumt eoal particles can be released by open pit mining coal stored at industrial sites for the produetion of coke, gas or steam, is subjected to erosion moreover, eoal naturally eroded into aquatic systems for sedimentary rock outcroppings containing coal seams. Oeeurrence of coal in sediments was reported from harbors such as Hamilton Harbour [2] and Roberts Bank coal terminal, in Canada [3]. Coal particles present in sediments made up 10.5 to 11.9 % dry weight of the soil mass in the vicinity of coal-loading terminals and was reported as non-hydrolysable solids.
