Aquatic Invertebrates thiab Dej muaj kuab paug

txawv hom ntawm cov dej invertebrates yuav ciaj sia nyob rau hauv polluted dej , thaum lwm tus ua tsis tau. Yog li ntawd, cov kws tshawb fawb feem ntau coj cov qauv ntawm cov invertebrates nyob hauv ib dej qhov chaw thiab siv tus hom nyob rau hauv tus qauv los ntsuas qhov theem ntawm ua paug hauv dej.

Hais txog qhov no, cov ntsuas dab tsi tuaj yeem siv los ntsuas dej zoo?

Cov no yog cov tseem ceeb ntsuas dej zoo:

• Dissolved oxygen (DO) DO test ntsuas cov pa oxygen yaj hauv dej.
• Dej kub. Cov kab mob hauv dej yog nyob ntawm qee qhov kub thiab txias rau kev noj qab haus huv zoo.
• pH.
• Escherichia coli (E.
• Specific conductance.
• Nitrates.
• Pob tshab.
• Kev kuaj pom.

Ib yam li ntawd, peb tuaj yeem siv Bioindicators los qhia seb cov dej puas zoo? Bioindicators tuaj yeem nthuav tawm cov teebmeem biotic tsis ncaj ncees ntawm cov pa phem thaum ntau lub cev lossis tshuaj ntsuas tsis tuaj yeem. Los ntawm bioindicators , cov kws tshawb fawb yuav tsum tau soj ntsuam tsuas yog ib qho qhia txog hom kuaj ntawm ib puag ncig es tsis saib xyuas tag nrho cov zej zog.

Kuj nug, dab tsi yog 6 lub ntsiab lus qhia txog dej zoo?

Cov qhov tseem ceeb ntawm cov dej zoo Cov kev ntsuas uas yuav tsum tau hais thaum muaj xwm txheej ceev yog bacteriological ntsuas ntawm fecal contamination, dawb chlorine residual, pH, turbidity thiab tejzaum nws conductivity / tag nrho yaj yaj.

Yuav ua li cas ntsuas hom pab cov kws tshawb fawb soj ntsuam kev noj qab haus huv ntawm lub ecosystem?

Qhov taw qhia hom (IS) yog tsiaj, nroj tsuag, los yog kab mob siv rau saib xyuas kev hloov pauv hauv peb ib puag ncig. Piv txwv li, lawv ua tau qhia peb txog qhov cuam tshuam ntawm kev ua qias tuaj rau ib qho ecosystem , lossis zoo npaum li cas ib puag ncig kev puas tsuaj raug tswj lossis rov qab los.
