Cov ntaub ntawv Blue-Green Algae

Blue-Green Algae (tseem hu ua cyanobacteria) yog cov kab mob ntuj tsim muaj nyob thoob plaws ntiaj teb hauv dej hiav txwv thiab dej tshiab. Qee qhov xwm txheej - cov dej tsis tshua muaj, tsis muaj dej tsis txaus, nce qhov kub thiab lub teeb, thiab lwm yam - tuaj yeem ua rau xiav-ntsuab algae tawg thiab, qee zaum, tso co toxins. Cov kws tshawb fawb tsis paub tias dab tsi ua rau xiav-ntsuab algae ua rau muaj kuab lom. Peb paub tias cov paj no loj tuaj thoob ntiaj teb.

Nyob rau hauv 2014, lub Park District muaj nws thawj puas muaj tshuaj lom algae tawg. Peb qhov xwm txheej ntawm cov kab mob lom tau raug sau tseg rau xyoo ntawd, feem ntau yuav yog vim huab cua qhuav. Ob lub paj tawg tau tshwm sim hauv Lake Temescal hauv Oakland. Ob lub paj ua rau lub pas dej kaw ua luam dej rau tag nrho li cuaj lub lis piam thaum lub caij ntuj sov thiab lub caij nplooj zeeg. Lwm lub paj tau pom hauv Lake Chabot. Txij li thaum xyoo 2014, Lub Nroog Park tau tsim ib qho kev saib xyuas Harmful Algal Bloom (HAB) kom muaj kev nyab xeeb hauv peb cov pas dej. Txog rau tam sim no, xiav-ntsuab algae blooms thiab co toxins tau pom nyob rau hauv tag nrho cov loj Park District dej lub cev. 

Cov feem ntau xiav-ntsuab algae toxins yog Anatoxin-A, uas cuam tshuam rau lub paj hlwb, thiab Microcystin, uas cuam tshuam rau lub siab. Kev raug algae lom, tsis hais los ntawm kev noj los yog kev sib cuag ntawm daim tawv nqaij, tuaj yeem ua rau pob khaus, tawv nqaij thiab qhov muag, ua xua, teeb meem plab hnyuv lossis, thaum noj ntau, mob hnyav lossis tuag, raws li California Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv. Hauv ob peb xyoos dhau los, ntau tus dev tuag hauv California tau raug ntaus nqi los ntawm kev lom algae lom. Txhawm rau kom cov ntses muaj kev noj qab haus huv thoob plaws hauv Cheeb Tsam Chaw Ua Si, txhua xyoo kev kuaj ntses cov co toxins raug ua ntawm cov pas dej loj hauv Park District. Tsis tas li ntawd, qhov tshiab thiab txhim kho Del Valle cov nroj tsuag dej haus tau sim tsis tu ncua kom ntseeg tau tias cov paj tawg paj tsis cuam tshuam rau cov dej haus tau los ntawm lub reservoir.. Yog xav paub ntxiv txog xiav-ntsuab algae thov mus saib hauv CCHABS website.

Raws li qhov cuam tshuam ntawm kev hloov pauv huab cua txuas ntxiv mus ntxiv, peb cia siab tias yuav pom lub sijhawm nce ntxiv thiab zaus ntawm cov teeb meem algal blooms. Lub Chaw Ua Si Hauv Cheeb Tsam tab tom siv ntau hom kev tswj hwm cov tswv yim los sim thiab txo cov paj thiab kho cov xwm txheej ua rau cov paj tawg. Thaum Lub Xya Hli 2020, lub tshuab hluav taws xob hypolimnetic oxygenation (HOS) tau teeb tsa ntawm Lake Anza hauv Tilden Regional Park. Lub hom phiaj ntawm qhov system no yog txo qhov zaus thiab lub sijhawm ntawm cov tshuaj lom tawg los ntawm kev ntxiv cov pa oxygen mus rau qhov tob ntawm Lake Anza. Oxygen khi cov as-ham tseem ceeb ua rau lawv tsis muaj rau kev loj hlob xiav-ntsuab algae. Ntawm Lake Temescal, daim ntawv thov kev sib koom ua ke tau siv los txwv thiab tswj HABs.
