“…The sticky and elastic carbohydrate skins of colonies can block the cooling water system of nuclear power plants (He et al, 2019b;Wang et al, 2021). Colony skin reportedly blocked the entrance of the cooling water filtration system of the Fangchenggang Nuclear Power Plant in China (Kang et al, 2020). According to the historical datasets and field investigation of this study, Phaeocystis blooms were not found in Fuqing nuclear power plant but were detected in July and October in lower abundance (0.07×10 5 cells/L, 0.11×10 5 cells/L), so may become a germplasm source of Phaeocystis blooms (Table 3, Figure 6).…”

“…In July 2014, the water intake of the Hongyanhe nuclear power plant in northern China was blocked by A. aurita, resulting in a 10 day shutdown (Zhang et al, 2019). From December 2014 to February 2015, a bloom of Phaeocystis globosa erupted in the area of the Fangchenggang nuclear power plant, blocking some filtration equipment to varying degrees (He et al, 2019b;Kang et al, 2020). In January 2015, Acetes chinensis, Acetes erythraeus, and Acetes japonicus tripped the single circulating pump in Daya Bay nuclear power plant (Meng et al, 2018).…”

“…This was the most serious economic loss caused by HABs reported in China (Lin et al, 2016). Once a large number of HABs organisms gather, the rotating filter screen (usually 3 or 5 mm) of the circulating water filtration system can be blocked, tripping the seawater circulating pump of nuclear power plants (Deretz, 2007;Mark, 2012;Fu et al, 2019;He et al, 2019b;Zhang et al, 2019;Kang et al, 2020). Therefore, as a potential risk organism, phytoplankton may accumulate, with a high number of cells that then deposit on the filter screen surface.…”

The invasion or aggregation of marine biota in coastal waters has become a common problem, threatening the safety of cooling water systems in the context of environmental and climate changes. However, studies on issues of coastal nuclear power plants from the view of marine ecology have mostly focused on the thermal effluent, entrainment effect on organisms, residual chlorine, radioactivity, etc. There is a lack of information on the safety of cooling water systems in nuclear power plants blocked by marine biota. Based on field and historical datasets, this study screened phytoplankton species that may potentially block the cooling water system of the Fuqing nuclear power plant on the Southeast China coast, identified the phytoplankton risk and a risk calendar, and established a catalog of risk phytoplankton species for the cooling water system. The screening criteria were simultaneously required as follows: (1) particle size of cells or group >2000 μm; (2) phytoplankton bloom or aggregation events occurred in surrounding areas; (3) and species abundance maintained at >0.5×105 cells/L in the surrounding area. Nine high-risk species were screened out that can easily form colonies, clusters, and groups, including Thalassiosira diporocyclus, Thalassiosira subtilis, Noctiluca scintillans, Phaeocystis globosa, Pseudo-nitzschia pungens, Pseudo-nitzschia delicatissima, Skeletonema costatum, Skeletonema dohrnii, Paralia sulcata. Due to small cells or the formation of short chains, some dominant phytoplankton species, even those with advantages in abundance and occurrence, had difficulty threatening the reliability of cooling water systems in nuclear power plants. The outbreak of different phytoplankton species varied daily, and the risk of blockage was highest from April to July. The biological characteristics, ecological mechanisms underlying outbreaks of high-risk phytoplankton species are reviewed and discussed, suggesting a high degree of temporal and spatial variability of blockage risk. Finally, main prevention and control measures used against high-risk phytoplankton species are provided to imply new ideas and methods for nuclear power plants. These strategies have very important practical and scientific significance.

Fluorine widely exists in nature, and its element is one of the most oxidizing substances among all elements. It can even react with some inert gases to form corresponding fluorides. Due to this special chemical property, fluorine has a wide range of applications in many fields including medicine, chemical industry, aerospace and atomic energy. Therefore, the development of water defluorination technology is related to human health and happy life, as well as environmental health and water quality safety. The research purpose of this paper is the biological monitoring index of fluorine pollution animal husbandry ecological environment based on machine learning algorithm. Using machine learning algorithm and diversity index in the experiment, from the alarm value and grading standard of poultry manure load, the environmental impact of fluorine-contaminated livestock and poultry manure and other pollutants, and the biological monitoring of fluorine-contaminated livestock and poultry ecological environment three aspects of the indicators were analyzed experimentally.

“…Beibu Gulf has long been regarded as the last clean sea zone in Chinese coastal waters. However, the number, scale, and areas of algal blooms in the region have significantly increased recently, and the number of species causing HABs has also increased [ 17 , 18 ]. Accurate identification of causative species is the biological basis for HAB prevention and monitoring.…”

The frequency of harmful algal blooms (HABs) has increased in China in recent years. Information about harmful dinoflagellates and paralytic shellfish toxins (PSTs) is still limited in China, especially in the Beibu Gulf, where PSTs in shellfish have exceeded food safety guidelines on multiple occasions. To explore the nature of the threat from PSTs in the region, eight Alexandrium strains were isolated from waters of the Beibu Gulf and examined using phylogenetic analyses of large subunit (LSU) rDNA, small subunit (SSU) rDNA, and internal transcribed spacer (ITS) sequences. Their toxin composition profiles were also determined using liquid chromatography-tandem mass spectrometry (LC-MS/MS). All eight strains clustered in the phylogenetic tree with A. pseudogonyaulax, A. affine, and A. tamiyavanichii from other locations, forming three well-resolved groups. The intraspecific genetic distances of the three Alexandrium species were significantly smaller than interspecific genetic distances for Alexandrium species. Beibu Gulf isolates were therefore classified as A. pseudogonyaulax, A. affine, and A. tamiyavanichii. No PSTs were identified in A. pseudogonyaulax, but low levels of gonyautoxins (GTXs) 1 to 5, and saxitoxin (STX) were detected in A. tamiyavanichii (a total of 4.60 fmol/cell). The extremely low level of toxicity is inconsistent with PST detection above regulatory levels on multiple occasions within the Beibu Gulf, suggesting that higher toxicity strains may occur in those waters, but were unsampled. Other explanations including biotransformation of PSTs in shellfish and the presence of other PST-producing algae are also suggested. Understanding the toxicity and phylogeny of Alexandrium species provides foundational data for the protection of public health in the Beibu Gulf region and the mitigation of HAB events.
