ABSTRACT=ObjectiveTo conduct a systematic review of the evidence regarding the impact of environmental health factors, such as air pollution, thermal stress, water and soil pollution, agricultural instability, and occupational hazards, on seasonal migration in China.MethodsA systematic review of PubMed, Web of Science, CNKI, Scopus, and Google Scholar (2001–2025) was conducted to identify peer-reviewed articles and institutional reports on environmental exposure, health, and migration outcomes in the Chinese mainland’s populations.ResultsOutmigration trends were found to be associated with each of the four aspects of air pollution, heat stress, water contamination, and agricultural instability during the winter, and, in addition to the above, water and soil contamination, in the summer. The effects were found to be strongest among rural poor and older individuals. At urban destinations, migrants were also at risk of occupational hazards due to silica dust and chemicals.ConclusionThe environment exerts a multidimensional, seasonal influence on internal migration in China. There is a need for coordinated environmental health governance to minimize migrant exposure and promote health equity in this population.
