The distribution characteristics of three groups of persistent organic pollutants (POPs), 21 organochlorine pesticides (OCPs), 18 polychlorinated biphenyls (PCBs) and 16 polycyclic aromatic hydrocarbons (PAHs), in different parts of bamboo shoots and bamboo shoots from different harvest seasons and producing regions in Zhejiang province were studied. The results showed that the distribution of OCPs was more abundant in the shoot than in the shell, and in the upper part of the shoot than in the lower part, and it was four-fold higher in spring bamboo shoots than in winter bamboo shoots.The level of OCPs pollution was higher in bamboo shoots from Shangyu than in those from other regions. Toxaphene was the most abundant among these OCPs (about 105 μg/kg). The distribution of PCBs was higher than in the shoot that in the shell, in the bottom part than in the upper part, and in spring than in winter. The level of PCBs pollution in bamboo shoots from Wuyi was the highest, and PCB52 was the most abundant PCB (1.14 μg/kg). The distribution of PAHs in the shoot was close to that in the shell, slightly higher in the upper part than the bottom part, and 1.5 times higher in spring than in winter. The highest level of PAHs distribution was found in bamboo shoots from Yongjia, and the most abundant PAH was phenanthrene (5.85 μg/kg). None of the 55 POPs in bamboo shoots exceeded the limits specified in the existing standards and were at a relatively safe level. This study not only improves the theoretical basis for bamboo shoot quality and safety, but also provides reference and support for the remediation and management of environmental pollution. © 2021, China Food Publishing Company.
