pollution are listed in Keller [Table 14.3‚ 2011]. Typical pollutants include: • Oxygen-demanding waste: materials that produce a high BOD [Fig. 11.2‚ Keller‚ 2000] • Pathogens: disease-causing microorganisms • Nutrients – often lead to eutrophication [Fig. 14.6a-c‚ Keller‚ 2011]. – see Gulf “Dead Zone” below and worldwide map of reported dead zones 2 • Oil: e.g Exxon Valdez spill‚ BP Macondo Well blowout • Toxic chemicals: organic compounds‚ heavy metals (e.g. mercury)‚ radioactive

Ocean Pollution “Over 80% of marine pollution comes from land-based activities” (WWF‚ May 4‚ 2006‚ p.1). The rest comes from ocean-based activities. Different types of pollution enter the ocean each year. The major pollutants are oil‚ toxic materials‚ and debris. These materials not only pollute the ocean‚ but they also affect the marine life. Before the 1970s there were no laws to prevent and stop people from dumping pollutants into the ocean. Since the early 1970s many laws and regulations

“Road salt” is a common term used for some chloride salts‚ including sodium chloride (NaCl)‚ which are used as de-icing agents on roads. The application of these de-icers on roads and other impervious surfaces in North America during winter months was in practice since the 1960s. The amount of snow fall is so high in these areas that snow and ice management becomes very essential to prevent road accidents‚ to maintain a continuous flow of traffic and to ensure safe pedestrian travel during winter
