Results of study: soil was polluted with Cd (6.2 times higher than Vietnamese standards). Vegetables (cabbages, salads, water morning glories) growing on this soil also contained high concentration of Cd. Initially, chicken excrement was determined as main resource of Cd pollution in soil and vegetables growing in studied area.
