Through the history of railways, wooden crossties impregnated with potentially hazardous creosote tar, have been used for years. There are six major classes of compounds in the creosote: aromatic hydrocarbons; tar acids/phenolics; tar bases/nitrogen-containing heterocycles; aromatic amines; sulfur-containing heterocycles; and oxygen-containing heterocycles. The creosote molecules applied in railway crossties can be released in the environment and they can bioaccumulate in animals and vegetables. Some constituents (benzo(a)pyrene and phenolics like benzene) are considered as being carcinogenic which renders the entire complex of creosote to be classified as potentially carcinogenic. After several decades of use the railway-ties are been recycled for varies uses like fences, stakes for agriculture and fruit production or bank protection. In this paper are examined some environmental and sanitary risks from wood impregnated with creosote reported in the literature.
在铁路发展历程中,浸渍有潜在危险的杂酚油沥青的木枕已使用多年。杂酚油中有六大类化合物:芳烃;焦油酸/酚类;焦油碱/含氮杂环化合物;芳香胺;含硫杂环化合物;以及含氧杂环化合物。应用于铁路木枕的杂酚油分子会释放到环境中,并在动植物体内生物累积。一些成分(如苯并(a)芘和苯等酚类)被认为具有致癌性,这使得整个杂酚油复合物被归类为潜在致癌物。经过几十年的使用后,铁路木枕被回收用于各种用途,如围栏、农业和水果生产用的木桩或河岸防护。本文研究了文献中报道的浸渍杂酚油木材带来的一些环境和卫生风险。
