Pollutant legacy

The literature on acid rain is simply vast. One of the better introductory texts is Acid Rain Its Causes and its Effects on Inland Waters, by B. J. Mason, Clarendon Press, Oxford, 1992. Dozens of Websites supplement and update Mason s book. For a general but more widely ranging survey of pollution and its legacy, try Pollution Causes, Effects and Control (fourth edition), edited by Roy M. Harrison, Royal Society of Chemistry, Cambridge, 2001. 

What is perhaps most notable about Olmsted s legacy is that these very constructed natural environments-Boston s Emerald Necklace was built on polluted mudflats-are largely not recognized as such today. Niagara Ealls and Yosemite, both carefully reworked in Olmsted s designs, ironically represent for...

The physico-chemical properties of these POPs are illustrated in Fig. 2.2. APs and PFAs (hydrophilic substances) are relatively more water soluble than the legacy POPs, which suggests that these pollutants could easily reside in water column and then can be carried to remote areas by hydrospheric movement (Yamashita et al., 2005). 

This chapter takes us through the names, structures, and stories of some of these legacy pollutants and of some of their replacements that are now in common use. But first we need a bit of an overview. 

Classes of Chiral Legacy and Persistent Organic Pollutants... 

Little work has been done on POP enantiomers in wastewater and activated sludge, in part because other sources to the environment exist compared to some emerging pollutants such as drugs [29]. One of the few studies to investigate behavior of chiral legacy POPs in... 

The use of stable isotopes of mercury to track pathways of inputs and uptake is innovative. The additions will be increased over time to levels comparable to the current mercury deposition in the northeastern US. The work is ongoing and, as of 2002, one paper has been published (Hintelmann et al., 2002). We wish to reemphasize that in productive near-shore regions of marine ecosystems, the legacy of pollution derived mercury in the surficial sediments is likely to predominate over new mercury as a substrate for methylation. The intense bioturbation in coastal marine sediments can keep much historical mercury active, relative to the more quiescent sediments of lakes. Unfortunately, the mechanistic predictions for declines in fish mercury levels following controls on mercury emissions, derived from the anticipated successful METAALICUS program, will not be applicable to the marine environment.

Here is a typical example of a relevant problem an ancient Sardinian hillside mine. The island of Sardinia has been mined for silver, zinc, copper, and lead since Phoenician and Roman times and, until the 1970s, was the largest source of heavy metals in Europe. It has left a legacy of pollution problems associated with mine drainage, carrying pollutants from hillside mines down to valleys below. This is a situation that could well be applicable to treatment by an electrokinetic barrier. The application is as shown in Figure 16.1.
