“…This study was conducted in two ‘Fuji’ apple orchards: the first, located near the city comprises approximately 5 acres of flat land at the Hot Springs Experimental Base of the Institute of Pomology, Chinese Academy of Agricultural Sciences (E: 120.72, N: 40.61); the second, located in a rural area, spans approximately 10 acres on the sunny side of a hilly, gentle slope, approximately 40 km away from the city (E: 120.14, N: 40.65) (Fig. 1 ) 42 . A total of 24 trees selected in our study were evenly distributed between the two orchards (not on the border).…”

The diverse fungal communities that colonize fruit surfaces are closely associated with fruit development, preservation and quality control. However, the overall fungi adhering to the fruit surface and the inference of environmental factors are still unknown. Here, we characterized the fungal signatures on apple surfaces by sequencing internal transcribed spacer 1 (ITS1) region. We collected the surface fungal communities from apple fruits cultivated in rural and peri-urban orchards. A total of 111 fungal genera belonging to 4 phyla were identified, showing remarkable fungal diversity on the apple surface. Comparative analysis of rural samples harboured higher fungal diversity than those from peri-urban orchards. In addition, fungal composition varied significantly across apple samples. At the genus level, the protective genera Coniothyrium, Paraphaeosphaeria and Periconia were enriched in rural samples. The pathogenic genera Acremonium, Aspergillus, Penicillium and Tilletiposis were enriched in peri-urban samples. Our findings indicate that rural samples maintained more diverse fungal communities on apple surfaces, whereas peri-urban-planted apple carried potential pathogenic risks. This study sheds light on ways to improve fruit cultivation and disease prevention practices.

“…Several rivers flowing through cities and industrial districts are discharging into the bay Pan et al, 2011a;. Besides, Laizhou Bay is surrounded by Shandong Province, which is a major CP-product supplier and has been proven to emit the highest levels of SCCPs into the atmosphere in China from 2008 to 2012 (Jiang et al, 2017;Zhang et al, 2017).…”

The concentrations of short-and medium-chain chlorinated paraffins (SCCPs and MCCPs) were measured for riverine and marine sediments from the Laizhou Bay area in order to investigate their spatial distributions, possible sources and transport behaviors. Concentrations of SCCPs and MCCPs in riverine sediments varied from 8.4 to 2000 ng g À1 dw and from 1.8 to 3200 ng g À1 dw, respectively. Higher concentrations were found exclusively at industrial sites. Emissions from local factories were the main source of CPs in river sediments of this region. It was 5e22 ng g-1 dw and 6e63 ng g À1 dw with an average value of 11 ng g À1 dw and 9 ng g À1 dw for SCCPs and MCCPs in marine sediments of Laizhou Bay, respectively. In addition to riverine input, ship related emissions are suggested to be another important source of CPs in the Laizhou Bay. MCCPs/SCCPs values and compositional profiles of SCCPs were found to vary along with CP concentrations. A distinct shift to congener groups with shorter carbon chains and lower chlorination from emission sources to remote areas was noticed. The role of log octanol-water partition coefficient (LogK ow ) values indicated decisive in their transportation from emission sources to remote areas in the Laizhou Bay area.

“…China has emerged as the largest producer and consumer of CPs worldwide. Annual production volumes have increased rapidly from 515,000 tons in 2007 to 1,124,000 tons in 2013 and are estimated to grow at an annual rate of 10.9% or higher in the future (Zhang et al, 2017). However, no rigid measures have been taken in the CP commercial market in China until now.…”
