EFFECTS OF INDUSTRIAL WASTE WATER OF YAZD-BAF FACTORY ON SOIL AND PLANTS

The objective of this study was investigation the effects of industrial textile water on soil and plant. For conducting this research Yazd-baf factory the major important textile factory was selected and sampling did in 2 stages and in 2 years. The waste water pH, TDS, TSS, sulfate, chloride, bicarbonate, N-NO3, salinity and concentration of Cu, Zn and Cd were above permissible limit. On soils Zn and Cd were in critical range. In addition soils had higher amounts of organic matter, N and available P and K compare to control sample. Concentration of Zn and Cu in plants was over permissible limit and concentration of heavy metals in shoots and roots in plants were different. Results showed that industrial water have limitation for application of irrigation, surface water and subsurface water. Use of these waters causes pollution of environment and transferred poisonous compounds in food chain.
