Waukulu mavuto chilengedwe Nyanja Black

Panopa, Nyanja Black ndi mbali yofunika ya Atlantic ndipo ali m'dera la 420.325 Km ^2. Kuli mitundu zikwi zitatu a nyama ndi zomera. Chochititsa chidwi n'chakuti zonse zosiyanasiyana pamwamba imapezeka pa akuya palibe mamita oposa 150. Komanso kugwa pansi pa ichi, mpaka pansi kwambiri, mukhoza penyani anasiya zamoyo ndi kuchotserapo ochepa mu mawonekedwe a mabakiteriya anaerobic. Ichi ndi chifukwa zigawo zozama za madzi kuimira njira zimalimbikitsa wa sulphide wa hydrogen. Izi chilengedwe zowononga kwa anthu onse amene ayenera mpweya chifukwa kugwira ntchito bwinobwino.

Nyanja Black: mavuto zachilengedwe

Ngati wina aliyense masiku ano madzi ndi nyanja ndi pansi pa chikoka zoipa zinthu anthropogenic. Chaka matani mazana a zinthu zoipa akatulutsidwa mu dziwe ake. Pakuti zoipitsa akhoza bwinobwino zimachitika onse organic ndi mchere feteleza, amene mowolowa manja ukala nthaka chifukwa zokolola bwino. Ndi iwo amene kugwera nyanja ndi kudziunjikira mu madzi, imfayo yogwira kubalana a timayandama. Otmiraya ngati zamoyo zimawononga mpweya ali misa madzi ndipo potero kudzetsa mavuto ena. Black Sea makalapeti wosanjikiza lonse la algae akufa, amene akukhala zambiri chaka chilichonse. Mothandizidwa chinthu ichi m'madera pansi mpweya akusowa kumachitika.

mavuto chilengedwe Nyanja Black linanena mwa zifukwa zotsatirazi zoipa:

1. kuipitsidwa kwa mitsinje mu izo, zimbudzi Madzi a mvula. Iyi imalimbikitsa osati kuchepa chilungamo madzi ndi maluwa nyanja, komanso kuwonongedwa kwa algae multicellular.

2. kuipitsidwa wa misa madzi mafuta. Chotero mavuto a zachilengedwe a Nyanja Black ndi zambiri zopezeka mu dera la kumadzulo kwa malo, kumene ali madoko ambiri ndi ambiri Pamadzi lapansi. Chifukwa ndi imfa ya kuchuluka kwa nyama ndi zomera, kusokoneza moyo zawo, komanso chikhalidwe cha kuwonongeka kwa mpweya chifukwa evaporation mafuta ndi ena ofanana.

3. kuwononga katundu madzi misa ya zochita za anthu. mavuto zachilengedwe ndi zotsatira za Black Sea Popanda kuchitapo kanthu ndi inadequately ankachitira zimbudzi. Katundu waukulu imagwera pa gawo kumpoto chakumadzulo kwa dera. Palinso malo waukulu wa nsomba spawning ndi kuswana mitundu yosiyanasiyana ya zinyama ndi mbalame. Chinthu china chochititsa chidwi ndi yogwira nyumba gombe. Chifukwa, pamwamba pansi pa Black Sea alumali ndi zakhudzana ndi zatsalira fumbi ndi simenti mankhwala ntchito yomanga.

4. Mfundo oterewa mulinso misa-nsomba kumatanthauza kuti mosalephera ndi kukonzanso lonse zinthu zachilengedwe m'madzi.
