Pesticide residues in market products pose a serious threat to consumers' health. This study aimed to analyze pesticide residues in agricultural products in the Chinese market. According to the data on agricultural products exceeding maximum residue levels (MRLs) obtained by the market supervision administration, 5387 batches of agricultural products (BAPs) in the Chinese market from 2011 to 2020 were extracted. The basic information of the data, time, region, crops and pesticides were discussed. The characteristics and trends of unqualified pesticide residues (UQPRs) in the Chinese market were statistically analyzed. The results showed that the BAPs withUQPRs increased over time, mainly occurring in spring and autumn. Most of the crops with UQPRs were leafy crops, among which Leek and Celery accounted for 28.3% and 16.9% of the total, respectively. Meanwhile, the regions with the most BAPs were Shandong, Henan, and Chongqing. Combining the statistical results and analyzing the reasons, the occurrence of UQPRs can be reduced from three aspects: government, market, and farmers. [Display omitted] • Establishing a database of unqualified agricultural products in China (2011–2020). • The region with the highest number of unqualified BAPs was Shandong; Leek and Procymidone were the most crops and pesticides in all unqualified BAPs. • May and September are the peak periods for the occurrence of excessive pesticide residues.
