Objective To understand the occurrence and distribution of Campylobacter jejuni in chicken in China, assess its health risk to the Chinese population, and provide recommendations for effective risk control. Methods Data from the National Food safety Risk Surveillance Network on Campylobacter jejuni between 2007 and 2010 and from published articles were analyzed. Eleven parameters were used based on the whole chicken preparation process and prevalence of Campylobocter jejuni for risk assessment by using the Ross-Sumner Method. Results The detection rates of Campylobacterjejuni in raw chicken were between 0.29% and 2.28% during 2007-2010 in China （more than 20 provinces）. The probability of illness caused by Campylobacter jejuni due to chicken consumption was around six out of one million consumers per day in urban areas and around one out of one million consumers per day in rural areas. Total predicted illnesses per year was about 736 000, accounting for 1.6‰ of the general population in urban areas and about 301 000, accounting for 0.37‰ of the total population in rural areas. The risk rankings of Campylobocterjejuni in chicken were 52 and 49 in urban and rural areas, respectively. Conclusion A high risk score for Campylobacterjejuni in chicken was obtained in China. This result may contribute to development of food safety management strategies. Key efforts should be made to control the risk of Campylobacterjejuni in chicken in China, especially in chick breeding and chicken preparation processes.

Empirical research indicates that heightened soil nitrogen availability can potentially diminish microbial decomposition of soil organic carbon(SOC).Nevertheless, the relationship between SOC turnover response to N addition and soil depth remains unclear. In this study, soils under varying N fertilizer application rates were sampled up to 100 cm deep to examine the contribution of both new and old carbon to SOC across different soil depths,using a coupled carbon and nitrogen isotopic approach. The SOC turnover time for the plot receiving low N addition(250 kg·ha^(-1)·yr^(-1) N) was about 20-40 years. Conversely, the plot receiving high N(450 kg·ha^(-1)·yr^(-1) N) had a longer SOC turnover time than the low N plot, reaching about 100 years in the upper 10-20 cm layer. The rise in SOC over the entire profile with low N addition primarily resulted from an increase in the upper soil(0-40 cm)whereas with high N addition, the increase was mainly from greater SOC in the deeper soil(40-100 cm). Throughout the entire soil layer, the proportion of new organic carbon derived from maize C_4 plant sources was higher in plots treated with a low N rate than those treated with a high N rate. This implies that, in contrast to low N addition agricultural practices, high N addition predominantly enhances the soil potential for fixing SOC by transporting organic matter from surface soils to deeper layers characterized by more stable properties. This research offers a unique insight into the dynamics of deep carbon under increased N deposition, thereby aiding in the formulation of policies for soil carbon management.

Municipal solid waste（MSW） is an important destination for abandoned plastics. During the waste disposal process, large plastic debris is broken down into microplastics（MPs） and released into the ***, current research only focuses on landfill leachates, and the occurrence of MPs in other leachates has not been studied. Therefore, herein, the abundance and characteristics of MPs in three types of leachates, namely, landfill leachate, residual waste leachate, and household food waste leachate, were studied, all leachates were collected from the largest waste disposal center in China. The results showed that the average MP abundances in the different types of leachates ranged from（129 ± 54） to（1288 ± 184） MP particles per liter(particles.L-1) and the household food waste leachate exhibited the highest MP abundance（p 80%） of small MPs（20–100 μm） in landfill leachates compared to other leachates. To the best of our knowledge, this is the first study discussing the sources of MPs in different leachates, which is important for MP pollution control during MSW disposal.
