Abstract:
Taking Cl-,SO2-4,HCO-3,NO-3,and Pb2+ ions as the experimental materials,the orthogonal experimental method was employed in potted plants to investigate the influence of salt ions in irrigation water on the Pb content in peppers,in order to provide reference for pepper cultivation in Urumqi.The results showed that,the Pb content in pepper fruits ranged from ND (not detected) to 0.040 mg·kg-1 (dry weight)，and from ND to 0.007 mg·kg-1 if calculated by fresh weight.It did not exceed the limit value (0.1 mg ·kg-1) in National Standards for Food Safety-Limits of Contaminants in Food (GB 2762-2017)；Cl- in irrigation water had the greatest effect on Pb content in root and stem of pepper，which was positively correlated with Pb content in root and close to a significant level，and negatively correlated with Pb content in stem.The negative correlation between SO2-4 and Pb content in stem was close to a significant level.The cumulative effect of anions in irrigation water on Pb content of pepper in Urumqi city was small.
