Divalent cations, particularly calcium, have been shown to enhance fouling of membranes with natural oiganic matter (NOM). Because is it s acidic nature, NOM can form complexes with dissolved metal ions. The strongest bonds occur with Ccdcium. This is a function of the size of the metal ion, it s electronic chaige, and the... 

Because the principle source of Hg to most locations is atmospheric deposition from distant emission somces, concentrations of HgT in unfiltered water samples from lakes and streams lacking local anthropogenic or geologic somces are usually in the range of 0.3 to 8 ng/L (Hmley et al. 1995 Babiarz et al. 1998 Krabbenhoft et al. 1999). However, natural dissolved oiganic matter (DOM) readily complexes...

Landfill G as Recovery. This process has emeiged from the need to better manage landfill operations. Landfill gas is produced naturally anaerobic bacteria convert the disposed oiganic matter into methane, carbon monoxide, and other gases. The quantity of methane gas is substantial and could be utilized as fuel, but generally is not. Most of the methane simply leaks into the surrounding atmosphere. 

Sulfur dioxide occurs in industrial and urban atmospheres at 1 ppb—1 ppm and in remote areas of the earth at 50—120 ppt (27). Plants and animals have a natural tolerance to low levels of sulfur dioxide. Natural sources include volcanoes and volcanic vents, decaying oiganic matter, and solar action on seawater (28,290,291). Sulfur dioxide is believed to be the main sulfur species produced by oxidation of dimethyl sulfide that is emitted from the ocean.
