Mercury is known as one of the most toxic heavy metals. Mercury contamination as low as 1-2 ppm could cause sudden dead in many living creatures such as panthers. Most soils and sediments contain only small amounts of mercury in nature. However those organic or muck soil usually have high dose. This paper will look at properties of organic soils in relation to their sorption capacity for mercury including forms and its toxicity. An understanding on status and basic background of mercury accumulation in soil will help planning for avoiding metal contamination in soil, sediment and water.
