Abstract
Single and joint effects of galaxolide( HHCB) and Cd on bacteria and fungi quantities in the soil incubated 10 weeks were investigated in the laboratory. The results showed that single and joint exposures of HHCB and Cd had significant impacts on bacteria and fungi quantities( P 0.01),except for Cd on bacteria. The growth of bacteria was inhibited firstly but promoted later after the applications of 500,1000 mg·kg- 1HHCB and 10 mg·kg- 1Cd singly and jointly. However,the single and joint exposures of 100,500 mg·kg- 1HHCB and 10 mg·kg- 1Cd promoted the growth of fungi. With the increase of HHCB concentration,the rate of inhibition decreased for bacteria during the 5th to 10 th week,while increased for fungi during the 1st to10 th week except for single HHCB in the 1st,4th and 10 th weeks as well as joint pollution in the4 th and 10 th weeks. It was suggested that the joint effects of compound pollution were synergistic on bacteria in the 1st week,but antagonistic on fungi from the 7th to 8th week.
