Selenium Content and/or T-2 Toxin Contamination of Cereals, Soil, and Children's Hair in Some Areas of Heilongjiang and Gansu Provinces, China.

Selenium Content and/or T-2 Toxin Contamination of Cereals, Soil, and Children's Hair in Some Areas of Heilongjiang and Gansu Provinces, China. Biol Trace Elem Res. 2019 Jan 03;: Authors: Sun L, Cui S, Deng Q, Liu H, Cao Y, Wang S, Yu J Abstract It has been strongly suggested that selenium deficiency and T-2 contamination in cereals are responsible for the development of Kashin-Beck disease (KBD). In order to assess these risk factors of KBD in the internal and external environments, our team undertook a two-stage survey in some areas of Heilongjiang and Gansu Provinces, China. The selenium content in children's hair (293), cereal (192), and soil (46) samples were determined using the 2, 3-diamino-naphthalene fluorometric assay technique. The T-2 toxin contamination level in the cereal samples (704) was assayed using an ELISA kit. There were no clinical KBD cases identified in this survey. The selenium statuses of the children in all the investigated regions during the first phase were at the medium selenium nutrition level. During the second phase, the selenium status of the children in Weiyuan County, Ning County, and Shangzhi City was at the medium selenium nutrition level, at the edge of selenium deficiency, and selenium deficient, respectively. Furthermore, the selenium contents in the cereal and soil samples were low. During the first phase, the average T-2 toxin contamination level in the family staple food samples for all th...
