Characteristics and sources of microplastic pollution in the water and sediments of the Jinjiang River Basin,Fujian Province,China

Microplastic pollution is widely distributed from surface water to sediments to groundwater vertically and from land to the ocean horizontally.This study collected samples from surface water,groundwater,and sediments from upper to lower reaches and then to the estuary in 16 typical areas in the Jinjiang River Basin,Fujian Province,China.Afterward,it determined the components and abundance of the microplastics and analyzed the possible microplastic sources through principal component analysis(PCA).As a result,seven main components of microplastics were detected,i.e.,polyethylene(PE),polypropylene(PP),polyvinyl chloride(PVC),polyethylene terephthalate(PET),polyformaldehyde(POM),nylon 6(PA6),and polystyrene(PS).Among them,PE and PP were found to have the highest proportion in the surface water and sediments and in the groundwater,respectively.The surface water,groundwater,and sediments had average microplastic abundance of 1.6 n/L,2.7 n/L and 33.8 n/kg,respectively.The microplastics in the sediments had the largest particle size,while those in the groundwater had the smallest particle size.Compared with water bodies and sediments in other areas,those in the study area generally have medium-low-level microplastic abundance.Three pollution sources were determined according to PCA,i.e.,the dominant agriculture-forestry-fishery source,domestic wastewater,and industrial production.This study can provide a scientific basis for the control of microplastics in rivers.

Tetraploid induced by physical and chemical methods in Jinjiang oyster（Crassostrea rivularis）

In order to induce tetraploid into Jinjiang oyster (Crassostrea rivularis), embryos were treated with physical (cold or heat shock) and chemical (chlorpromazinum or traditional Chinese medicine)methods in the first 3 min before the cleavage of zygotes or at the onset of the first cleavage of one or two eggs. Measurements show that the induction rates of tetraploid in the embryos inspected are 28%, 30%, 28. 4% and 35. 8% for heat-shock (39℃, 3 min),cold-shock (10℃, 3min),chlorpromazinum (0. 375 mg/dm3, 10 min) and traditional Chinese medicine (50 g/dm3 )extract (57 cm3, 10 min),respectively. The tetraploid induction rate in the larvae treated with traditional Chinese medicine is 32. 5%.It is evident that the induction rate of tetraploid in embryos insected at an early stage is the most remarkable when treated. with traditional Chinese medicine.

Spatial and Temporal Distribution Characteristics of Agricultural Non-point Source Pollution in Xixi Watershed of Jinjiang Basin

The SWAT model was applied to analyze the temporal-spatial distribution patterns of non-point source pollution loads and the difference of pollution loads of different land use types in Xixi Watershed of Jinjiang Basin. The results showed that both yearly nitrogen and phosphorus pollution loads were evenly distributed during 1973 to 1979,the annual TN pollution from non-point source was 1530 t,or 6. 3 kg / ha,and the annual TP pollution from non-point source was 270 t,or 1. 1 kg / ha during 1973 to 1979 in the watershed. Considerable differences were identified on both monthly nitrogen and phosphorus pollution loads. The TN and TP pollution loads during the flood season( from April to September) accounted for 76. 2% and 75. 8% of the annual load respectively. There were great differences in both TN and TP pollution loads of different land use types in the study area,and the pollution load of both farmland and orchard was higher than that of the other land use types. TN and TP pollution loads of farmland accounted for 66% and 83% of total watershed. There was a great spatial difference in the nonpoint source pollution load of the study area. The critical source areas of non-point source pollution are mainly located at Guanqiao Town,Longmen Town,Changkeng Town,Shangqing Town and Dapu Town,where the efforts of controlling pollution should be made.

Investigation on Sinipercine Fishes in the National Aquatic Germplasm Resources Protection Area in Jinjiang River of China

[Objective]The paper was to provide a scientific basis for protection and utilization of sinipercine fish resources in Jinjiang River,the national resources protection area. [Method]A total of 171 specimens of sinipercine were collected from Jinjiang River and its branches,identified and statistically counted.[Result]There were three species of wild sinipercine,including Siniperca scherzeri,Coreoperca whiteheadi and Siniperca kneri,with occurrence frequencies of100%,66. 7% and 50%,respectively. They were common species in the river,and S. scherzeri was dominant. The total allowable catch(TAC) of the three species was not big,and the individuals captured were generally small,and with rare mature individuals. [Conclusion]The resources of sinipercine had a preliminary recovery in the region after the foundation of the national resources protection area for aquatic resources in Jinjiang River in 2009.

Geological Disaster Evaluation of the Xixi Watershed of the Jinjiang River Based on the Coupling of Landscape and Multiple Factors

Six evaluation factors were selected to evaluate the susceptibility level of the Xixi Watershed to geological disasters such as collapse and landslide, namely formation lithology, rainfall, gradient, aspect, vegetation and buffer zone. The results showed that Longmen Town, Gongqiao Town, Lianhua Town, and Chengxiang Town in the lower reaches of the Xixi Watershed were more susceptible to geological disasters in case of rainstorm because of the easily-collapsed formation lithology; riverbank erosion by runoff was enhanced during rainstorm, thus both sides of the rivers in Chengxiang Town at the estuary of the Xixi Watershed were most susceptible to geological disasters; in case of rainstorm, geological disaster monitoring in location areas of Longmen Town, Guanqiao Town, Lianhua Town, Chengxiang Town in the lower reaches, particularly trunk streams in Chengxiang Town, should be enhanced. By evaluating environmental geo-disasters of the Xixi Watershed, the blank in the environmental geo-disaster evaluation of the local area will be filled in, and scientific support will be provided for the future prevention of environmental geodisaster.

Improving DNA Data Capacity:Forensic Parameters and Genetic Structure Analysis of Jinjiang Han Population with the Microreader^(TM) Y Prime Plus ID System

Objective Population genetic analysis based on genetic markers harbors valuable forensic applications.In this regard,it is informative and imperative to explore Han groups as they are the largest population of China.In particular,there is a largely underrepresented amount of information from recent decades regarding the southeast costal Han Chinese.Therefore,the aim of this study is to investigate the available genetic characteristics of the Han population living in the Jinjiang,Fujian Province,Southeastern China.Methods We sampled 858 saliva samples and used the commercially available Microreader^(TM) Y Prime Plus ID System to identify population data of Y-short tandem repeat(STR)loci of this region.Results A total of 822 different haplotypes were observed.The overall haplotype diversity,discriminatory power and haplotype match probability were 0.9999,0.9999 and 0.0012,respectively.Conclusion Our results showed that the Jinjiang Han population was closely genetically related to Han groups of China.Overall,we identified a set of 37 Y-STRs that are highly polymorphic,and that can provide meaningful information in forensic practice and human genetic research.

Jinjiang——Radiant and Vigorous

Luminescence chronology of “Old Red Sand” in Jinjiang and its implications for optical dating of sediments in South China

A weathered deposit in South China is widespread on the coastal areas of Fujian and Guangdong provinces,China.This deposit consists of slightly cemented,medium-to fine-grained sands,and is characterized by its colors of red,brown red,light reddish brown or dark yellowish orange,and is usually called "Old Red Sand".The uncertainty in its formation age has been a major obstacle to the study of this type of deposit.In this paper,optically stimulated luminescence(OSL) techniques were used to date the "Old Red Sand" sediments from Jinjiang,Fujian Province,China.The effect of the geochemical behavior of uranium and thorium in sediment during chemical weathering on estimation of annual dose was investigated.The results show that the change in annual dose due to weathering poses a major problem for the optical dating of such weathered sediments.The optical dating of these weathered deposits will produce erroneous ages if average annual dose during burial cannot be correctly estimated.For the profiles studied,the OSL dates obtained on samples from the upper part do not represent the burial age of the samples.It is highly likely that they are underestimated due mainly to the accumulated radioactive elements as a result of chemical weathering.It is concluded that changes in annual dose due to chemical weathering must be considered when dating similar sediments in South China.With a detailed analysis of the OSL dating results,the chronology of the marine terraces in this area was suggested.The lowest terrace was formed at ～3.5 ka and the second terrace was dated to ～74 ka.The age of the highest terrace may not be established accurately,but is inferred to be older than the apparent OSL date of～77 ka and so is the Paleolithic artifacts from it.

基于自动检测方法的福建地区断裂带地震活动性研究

利用福建地震台网88个地震台站于2015年记录的10个月的连续波形数据,基于台网约束下的长短窗特征触发式震相检测的模板事件识别方法和匹配滤波自动检测方法,识别出模板事件919个,匹配滤波后重新识别和定位了共计2243个地震事件,其中ML1.0以上地震1991次,主要集中在ML1.0—1.5之间,这极大扩充了该震级范围内的福建地震台网目录。重新定位的地震震源深度分布在0—20 km之间,多数发生在10 km内的上地壳。沿长乐—诏安断裂带和永安—晋江断裂带,地震分布集中且表现出明显的分段活动性。在长乐—诏安断裂带上检测到较福建台网目录更多的地震,且地震活动性表现为西南段较强、东北段较弱,沿断裂带的震源深度分布由南向北逐渐变浅,与莫霍面深度的变化相一致;在与之共轭的永安—晋江断裂带上则北西段地震活动更为集中,而东南段地震活动稍显分散。重新识别与精定位后的地震与福建地区地壳水平形变南强北弱、东强西弱的特点相一致。
