Kuwonongeka kwa madzi

M'nthawi yathu ino, kuipitsa madzi ndi koopsa kwambiri. Zimakhala zovuta kupeza madzi ovomerezeka kuti azimwa. Tiyeni tiyang'ane ena mwa mitundu yoopsa kwambiri ya kuipitsa madzi.

Kusokoneza kwa madzi kumabwera kuchokera ku mabungwe ogulitsa mafakitale komanso mabomba a nyumba, mabiliyoni ambirimbiri omwe amwazikana padziko lonse osati malo okha, komanso nyanja. Zomwe zimapangidwira, monga mapulasitiki, mapuloteni, mapuloteni, osambitsidwa kuchokera kuminda kapena mankhwala ophera tizilombo, omwe ena amagwiritsa ntchito powagwiritsira ntchito mozunza, amatanthawuza ntchito yopangira matabwa ndi zina zambiri zomwe sizikhoza kuwonongeka. , Koma amatha kutenga nawo mbali m'thupi la maselo amoyo, akuchitapo kanthu monga zowonongeka za njira zowonongeka.

Ndipo mankhwala ena omwe amachititsa kuti madzi asokonezeke akhoza kusinthidwa ndi zamoyo, koma nthawi zambiri amakhala mankhwala omwe amakhala oopsa kwambiri kwa zamoyo zamoyo kuposa zoyambirira. Zina mwazo ndi zotsimikizika za khansa (zinthu zomwe zimayambitsa mapangidwe a khansa), ena adatchula kuti matatogenic ndi mutagenic properties (ndiko kuti, chifukwa chogonana ndi anomalies kapena kusintha kwa zamoyo zamoyo). Zotsatira zake zimakhala ndi halogenated hydrocarbons, mankhwala ophatikizika ndi phenols.

Kuwonongeka kwa madzi ndi nitrites ndi nitrates n'koopsa kwa ana omwe ali ndi zaka zoposa khumi ndi ziwiri. M'mimba mwawo, sizinapangitse asidi okwanira kuti awononge mabakiteriya omwe amachititsa kuti nitrate mu nitrites oopsa kwambiri. Koma vutoli silikukhudza ana okha, makina a nitro amapangidwa m'madera ena ngakhale m'mimba mwa akuluakulu ndipo amachititsa kuti poizoni azidziwika bwino. Ndi mtundu uwu wa poizoni ana obadwa kumene, matendawa amayamba mhemhemoglobinaemia, yotchedwa "blue baby syndrome", ndi matendawa, erythrocytes amatha kunyamula mpweya, zotsatira za matendawa zingakhale zoopsa.

Zifukwa za kukula kwa khansara zimatha kukhala benzene ndi trichlorethylene komanso ngakhale asbesitosi. Ndipo ngati chitsogozo chilowa mu thupi, matenda aakulu a ubongo angayambe, makamaka ana akuvutika ndi izi.

Madzi ndi klorini mankhwala amakhala oipitsidwa, omwe amagwiritsidwa ntchito moyerekeza ndi kuyeretsedwa, koma kuwononga tizilombo toyambitsa matenda, nthawi yomweyo amadzaza madzi ndi mankhwala owopsa a organochlorine. Kuchokera ku chlorini, madzi amakhalanso ndi chisangalalo chosasangalatsa ndipo amalephera kuwonekera. Ndipo pochitika kuti mankhwala a organochlorine alowa thupi la mayi wokhala ndi pakati, akhoza kuyambitsa zilema zoberekera za mwana, monga malingaliro a mtima ndi ubongo.

Kuchokera ku manganese ndi chitsulo, madzi amapeza chimbudzi chakuda kapena chobiriwira, kukoma kwake kumachepa, kukula kwa mabakiteriya a chitsulo kumayamba. Kugwiritsiridwa ntchito kwa madzi otere nthawi yayitali kumathandiza kuti chitukuko cha matenda, magazi, chiwindi, chiwopsezo cha mtima chichitike. Kuwonongeka kwa madzi ndi mafuta kumabweretsa madzi osiyanasiyana zinthu zovuta zomwe zimapha anthu onse ndi zomera ndi zinyama za matupi a madzi.

Ndi nthawi yoti anthu aganizire za zochita zawo, asiye kusokoneza dziko lapansi, chifukwa zingathe kuchepetseratu chiwonongeko chotere monga anthu, mwa kayendetsedwe kake kochepa pa mapulaneti, mwachitsanzo, kutuluka kwa phiri lalikulu kapena kutuluka kwa kachilombo katsopano. Anthu ayenera kukonda zachirengedwe, ndipo adzabwezeretsanso kambirimbiri.
