The study of the antecedents of child maltreatment has advanced through ecological research, but there has been a limited focus on the role of community social capital. This study investigates the effects of community social capital on child maltreatment and how these associations differ by regional type, using data on child maltreatment rates in 226 localities in South Korea from 2014 to 2019. Surprisingly, our results show that social trust, networks, and engagement in community affairs are positively associated with child maltreatment rates. Additionally, the mechanisms of social capital effects on child maltreatment vary by place, being more pronounced in small‐ and medium‐sized cities and rural areas. Our findings suggest that a more nuanced understanding of social capital mechanisms across dimensions and locations is required to effectively address child maltreatment. This study contributes to both theory and practice by highlighting the importance of community social capital in preventing child maltreatment and demonstrating the contextual nature of these associations.

We investigated the distributions of the artificial radionuclides 137Cs, 239+240Pu, and 90Sr in the various marine products around Korean Peninsula collected in 2015–2017. The activities of 137Cs, 239+240Pu, and 90Sr were in the ranges of 12.2–258.4 mBq kg−1, 0.014–1.879 mBq kg−1, and 11.3–18.3 mBq kg−1, respectively. The higher 239+240Pu (a factor of 10–50) relative to fishes were observed in mollusks. 137Cs in fishes were significantly enriched with growths. The calculated concentration factors (CFs) of 137Cs, 239+240Pu, and 90Sr in marine products were 7–143, 3–407, and 15–25, respectively. Overall, no noticeable artificial radioactivity was detected in marine organisms when comparing these results with previous data reported before the Fukushima nuclear accident and recommended CF values. The annual effective doses of 137Cs, 239+240Pu, and 90Sr by seafood consumption in South Korea were estimated to be 1.1 × 10−4, 1.6 × 10−5 and, 2.9 × 10−5 mSv yr−1, respectively, which is insignificant relative to that of natural radionuclides. • Artificial radionuclides (ARs) were determined in marine products around South Korea. • No significant spatiotemporal variation of 137Cs, 239,240Pu, 90Sr in marine biota • 137Cs and 239,240Pu in marine biota could vary according to main habitats and growth. • 137Cs activity in fishes except salmon logarithmically correlated with body weight. • Annual dose of ARs were insignificant relative to those of natural radionuclides.
