11.TOXICOLOGICAL & ECOLOGICAL INFORMATION
Transfer and transform: The concentration of tin in nature freshwater is 4-90PPb, there is almost no tin checked out in many rivers and lakes, the concentration of tin in seawater is 3PPb, and tin in Pacific Ocean is 1.6PPb. It is steady of tin in water in strong acidic condition, If PH >2, it will be formed Sn(OH)2 which is deposit through alkaline salt(Sn(OH)X, Sn2 (OH) 2X2, Sn2OX2 and so on), if PH about 13, it will be dissolved. Stannous compound is a strong reducer and it will react with
O(oxygen) and then transform to stannic compound. So, most tin were existed in stannic. Dissolved tin were in form of ion which contain O and OH-, and it is primary existed states are Sn(OH)2+ and SnO(OH)3+. Tin can be transformed methylic
compound in lacking oxygen condition and formed methylic tin which was prone to volatilize form water to air. Tin can be enriched by all the plant and animal in water, and this made tin transfer from water to water plant and animal.
