I-Phytoremediation yindlela yokuhlaziywa kwaye isebenza kuzo zonke iikhemikhali okanye iinkqubo zenyama ezibandakanya izityalo zokuhlambalaza okanye ukuchitha ukungcola emhlabathini nasemanzini angaphantsi komhlaba. Igama (elingagqithisi ulwimi) lucacile. Livela kwigama lesiGrike elithi phyto lithetha "isityalo" kunye neliLatini igama lokulungisa isingiselo "ukubuyisela ibhalansi." Xa zihlanganiswa, amagama amabini abhekisela kubuchwephesha obusebenzisa izityalo eziphilayo ukuba zihlambulule umhlaba, umoya kunye namanzi anokuhlaselwa ngamachiza angozi.
Kutheni abantu basebenzisa iPhytoremediation
I-Phytoremediation yindlela echanekileyo yendlela yokulungiswa kwezityalo ezisebenzisekayo izityalo ukugxila kwizinto kunye nemimandla evela kwimo engqongileyo kunye nokuqukumbela iamolekyu ezahlukahlukeneyo kwizicubu zazo. Libhekisela kumandla okwenyama kwezityalo ezithile ezibizwa ngokuba yi-hyperaccumulators ukuze zidibanise, zihlaziye okanye zenze umonakalo onobungozi emhlabathini, amanzi, okanye umoya. Isinyithi esinobunzima besinyithi kunye nokungcoliswa kwamanzi yizona nto iinjongo eziphambili ze-phytoremediation. Ulwazi lweendlela zomzimba kunye nee-molecular of phytoremediation lwaqala ukuvela kwiminyaka yamuva nje kunye neendlela zobomi nezobunjineli ezijoliswe ekuphuculeni nasekuphuculeni i-phytoremediation. Ukongezelela, izilingo ezininzi zeegadi ziqinisekisile ukukwazi ukusebenzisa izityalo zokucoca kwendalo.
Ngoxa i-teknoloji ayintsha, iimeko ezikhoyo zibonisa ukuba ukuthandwa kwayo kukhula. Oku kuluhlu lweentlobo ezi-6 ezahlukeneyo zeprotoremediation ngeenkcazo ezichaza indlela abasebenza ngayo.
01 Ukunyanzeliswa kwamanzi
Kwakhona kuthiwa yi- phytostabilization . Iinkqubo ezininzi ezahlukeneyo ziwela phantsi kweli qela, ezinokubandakanya ukuxhamla ngeengcambu, ukukhangisa kwiindawo zengcambu okanye ukuveliswa kweekhemikhali zityalo ezikhutshelwe emhlabathini okanye emanzini angaphantsi kwimizi engcambu, kwaye iyakwazi ukukhawuleza, okanye ngenye indlela, ukukhupha izidakamizwa ezikufutshane.
02 Rhizodegradation
Oku kwenzeka kumhlaba okanye emanzini angaphantsi komhlaba ngokujikeleza izityalo zengcambu . Ukugqithiswa kwizityalo kukhuthaza i-rhizosphere ibhaktheriya ukuphucula i-biodegradation ye-contaminants yomhlaba.
03 I-Phytohydraulics
Ukusetyenziswa kwezilwanyana ezinzulu (ngokuqhelekileyo imithi) ukuba iqulethe, isetyenziswe okanye ihlaziye izidakamizwa zamanzi angaphantsi komhlaba ezidibana nazo. Omnye umzekelo walokhu, imithi yamapoplar yayisetyenziselwa ukuququza umquba wamanzi womhlaba we-methyl-tert-butyl-ether (i-Hong et al al. 2001. iNzululwazi yezoBume kunye neTheknoloji 35 (6): 1231-1239).
04 I-Phytoextraction
Kwakhona kwaziwa ngokuba yi-phytoaccumulation. Izilwanyana zithatha okanye ziqukumbela izidakamizwa ngeengcambu zazo zize zigcinwe kwiiscuzu zeqonga okanye amaqabunga. Izinto ezingcolileyo azikho phantsi koko zihlaziyiweyo kodwa zisuswa kwindawo yendalo xa izityalo zivunwa. Oku kunceda kakhulu ekususeni izitye ezisemhlabeni kwaye, kwezinye iimeko, izitye zinokubuyiswa ukuze ziphinde zisebenzise, ngokutshabalalisa izityalo, kwinkqubo ebizwa ngokuba yi- phytomining .
05 I-Phytovolatilization
Izilwanyana zithatha izixhobo ezinokuthi zixhamle ngeengcambu zawo, zize ziguqule iimveliso ezifanayo, okanye i-metabolites, ngokusebenzisa amaqabunga, ngaloo ndlela ziwakhulule emkhathini .
06 Phytodegradation
Iingcolisi zithathwa kwiifom zityalo apho zichithwe khona, okanye zi-biotransformed. Apho utshintsho lwenzeka khona kuxhomekeke kulolu hlobo lwesityalo, kwaye luyakwenzeka kwiingcambu, i-stem okanye amaqabunga.
