Ukrainos up\u0117se vis da\u017eniau fiksuojamas vandens \u017eyd\u0117jimas, kai spar\u010diai dauginasi melsvabakter\u0117s ir vanduo \u012fgauna \u017ealsv\u0105 atspalv\u012f, prast\u0117ja kvapas bei skaidrumas. Dnipro ir ma\u017eesni\u0173 upi\u0173 atveju tai siejama su kar\u0161\u010diais, silpna t\u0117kme ir \u012f vanden\u012f patenkan\u010diomis maistin\u0117mis med\u017eiagomis, ypa\u010d fosfatais.<\/p>\n
Dnipro valstybinio universiteto biologas Olehas Marenkovas teigia, kad vienu i\u0161 efektyviausi\u0173 nat\u016brali\u0173 b\u016bd\u0173 ma\u017einti tok\u012f \u017eyd\u0117jim\u0105 gal\u0117t\u0173 tapti baltasis pla\u010diakaktis, da\u017enai vadinamas vandens telkini\u0173 sanitaru. \u0160i \u017euvis minta planktonu ir gali suma\u017einti perteklin\u0119 dumbli\u0173 bei melsvabakteri\u0173 biomas\u0119, taip gerindama vandens kokyb\u0119.<\/p>\n
\u201eBaltasis pla\u010diakaktis yra perspektyvi r\u016b\u0161is biomanipuliacijai, ta\u010diau m\u016bs\u0173 s\u0105lygomis jis nat\u016braliai nesidaugina, tod\u0117l j\u012f reikia \u012f\u017euvinti dirbtinai\u201c, \u2013 sak\u0117 Olehas Marenkovas.<\/p>\n
Pasak mokslininko, vasar\u0105 \u017eyd\u0117jim\u0105 ypa\u010d skatina \u0161iluma ir l\u0117tas vandens atsinaujinimas, o papildomas \u201ekuras\u201c yra i\u0161 \u017eem\u0117s \u016bkio lauk\u0173 ir buitini\u0173 nuotek\u0173 \u012f upes patenkantys fosfatai bei tr\u0105\u0161os. Dalis smulki\u0173 \u017euv\u0173 planktonu minta tik i\u0161 dalies, tod\u0117l nat\u016brali kontrol\u0117 da\u017enai b\u016bna per silpna, kad sustabdyt\u0173 masin\u012f melsvabakteri\u0173 dauginim\u0105si.<\/p>\n
Biologas pabr\u0117\u017eia, kad pla\u010diakak\u010dio \u012f\u017euvinimas gali veikti kaip viena i\u0161 bioremediacijos priemoni\u0173, ta\u010diau tai n\u0117ra stebuklingas sprendimas. Jei maistini\u0173 med\u017eiag\u0173 patekimas \u012f vanden\u012f nema\u017e\u0117s, \u017eyd\u0117jimo rizika i\u0161liks, ypa\u010d per kar\u0161\u010dio bangas ir esant \u017eemai vandens t\u0117kmei.<\/p>\n
Ekspertai taip pat primena, kad melsvabakteri\u0173 \u017eyd\u0117jimas svarbus ne tik d\u0117l estetinio vaizdo ar kvapo. Kai kurios melsvabakter\u0117s gali gaminti toksinus, o j\u0173 suirimas vandenyje ma\u017eina deguonies kiek\u012f, didina \u017euv\u0173 dusimo ir ekosistem\u0173 disbalanso tikimyb\u0119, tod\u0117l sprendim\u0173 da\u017eniausiai reikia keli\u0173: nuo tar\u0161os ma\u017einimo iki geresnio nuotek\u0173 valymo ir tikslingo vandens telkini\u0173 tvarkymo.<\/p>\n","protected":false},"excerpt":{"rendered":"
