In addition to fish farming, which is a relatively recent phenomenon, hydroelectric power dependent chemical industry has been using fjords as recipient for waste for more than 50 years, particularly in Scandinavia and Canada. Smelters located at the head of fjords have contaminated water, sediments, and organisms with polycyclic aromatic hydrocarbons (PAHs) and heavy metals (Naes etal., 1995). The level of contamination in fish and shellfish exceeds safety levels established by the World Health Organization in 15 fjord locations in Norway, and their use for human consumption has been restricted. These... 

World Health Organization (WHO) (1980). Recommended Health-Based Limits in Occupational Exposure to Heavy Metals. Technical Report Series 647. Geneva. 

Results from the evaluation of ground water quality characteristics near two waste sites in Ibadan and Lagos revealed that some of the ground-water quality constituents determined exceeded the World Health Organization (WHO) standards for drinking water irrespective of source of pollution. Some of the ground-water samples were poor in quality in terms of cadmium, chromium, lead and nickel recorded (Deem et al., 2002). The levels of heavy metals (cadmium, chromium, nickel, and lead) were analysed in the River Ijana (Ekpa-...
