The Impact of Cyanobacteria Blooms on the Aquatic Environment and Human Health

Abstract

Cyanobacteria blooms are a global aquatic environment problem. In recent years, due to global warming and water eutrophication, the surface cyanobacteria accumulate in a certain area to form cyanobacteria blooms driven by wind. Cyanobacteria blooms change the physical and chemical properties of water and cause pollution. Moreover, cyanobacteria release organic matter, N (nitrogen) and P (phosphorus) into the water during their apoptosis, accelerating the eutrophication of the water, threatening aquatic flora and fauna, and affecting the community structure and abundance of microorganisms in the water. Simultaneously, toxins and carcinogens released from cyanobacteria can be enriched through the food chain/web, endangering human health. This study summarized and analyzed the research of the influence of cyanobacteria blooms on the aquatic environment and human health, which is helpful to understand further the harm of cyanobacteria blooms and provide some reference for a related research of cyanobacteria blooms.

Draft Genome Sequences of Bacteria with Cyanocidal Potential Isolated from Eutrophic Waters Associated with Cyanobacterial Harmful Algal Blooms

“…Cyanobacterial harmful algal blooms (cyanoHABs) can lead to deleterious effects on aquatic ecosystems and human health ( 1 ). These blooms can produce cyanotoxins (e.g., microcystins) with detrimental effects on wildlife, livestock, and public health ( 2 ). Because of this, fast-acting control methods (e.g., copper and hydrogen peroxide-based algaecides) are needed to mitigate cyanoHABs for the quick and efficient restoration of water quality ( 3 ).…”

Spatio-Temporal Variation of Cyanobacteria Blooms in Taihu Lake Using Multiple Remote Sensing Indices and Machine Learning

“…Cyanobacteria blooms can cause the deterioration of water quality, endanger human health, and destroy the balance of lake ecosystems [1]. As the water source for one of the most developed regions in China, the water quality of Taihu Lake has been constantly threatened by frequent cyanobacteria blooms since the 1980s [2].…”

Heterostructured CoS2/MoS2 with a Rich Active Site for an Efficient Electrochemical Nitrate Reduction Reaction to Ammonia

“…At the same time, the increasing and widespread distribution of nitrate (NO 3 – ) in the environment is a kind of pollution substance, which will lead to eutrophication of water but also pose a threat to human health. Gastrointestinal microbes in the human body can convert NO 3 – into nitrite (NO 2 – ), which leads to discomfort and even serious illness. − Recently, as a result of more frequent production activities, a lot of NO 3 – has been discharged into the environment. Therefore, we hope to find a way to convert NO 3 – into a product that is not harmful to organisms or even valuable.…”
