Their persistence and expansion are strongly linked to warmer water temperatures and human-driven alterations such as nutrient over-enrichment, water diversions, withdrawals, and salinization. Bloom-forming cyanobacteria can harm ecosystems and human health by suppressing beneficial phytoplankton, depleting oxygen during senescence, and producing cyanotoxins. Ongoing research examines how nutrients, light, temperature, oxidative stress, and biotic interactions regulate toxin production, guiding physical, chemical, and biological control strategies for natural and drinking waters.","","cbCairK5tXksys4Q","https://ap.wps.com/l/cbCairK5tXksys4Q","pdf",1019015,1,16,"English","en",105,"# Abstract\n# Introduction","[{\"question\":\"What environmental factors drive harmful cyanobacterial blooms?\",\"answer\":\"Harmful blooms are associated with higher water temperatures and anthropogenic changes such as nutrient over-enrichment (eutrophication), hydrologic alterations (diversions and withdrawals), and salinization. Nutrient supply rates, light, temperature, oxidative stress, and interactions with bacteria, viruses, and grazers also influence cyanotoxin production.\"},{\"question\":\"What consequences do cyanobacterial blooms cause?\",\"answer\":\"Cyanobacterial blooms can harm ecosystems and health by outcompeting beneficial phytoplankton, depleting oxygen when blooms senesce, and producing toxic secondary metabolites such as cyanotoxins.\"},{\"question\":\"Which control approach is emphasized for reducing bloom severity?\",\"answer\":\"A key underlying strategy is reducing nutrient inputs, especially nitrogen and phosphorus. Lower nutrient loading has been shown to reduce cyanobacterial biomass and limit health risks and the frequency of hypoxic events.\"}]",1782766843,40,null]
