791-31-1: Incazelo Yokuxhumanisa Eyisihluthulelo

Emkhakheni wamakhemikhali, i-ID 791-31-1 isho inhlanganisela ethize ehehe ukunakwa ezinhlelweni ezahlukahlukene zesayensi nezimboni. Lesi sihlonzi esiyingqayizivele siyingxenye yokubhaliswa kwe-CAS, enikeza isihlonzi senombolo esiyingqayizivele kukhemikhali ngayinye ukuze kube lula ukuxhumana nokucwaninga emphakathini wesayensi womhlaba.

Inhlanganisela ehlobene neI-CAS 791-31-1ibizwa nge-2,4-dichlorobenzoic acid (evame ukufushaniswa ngokuthi 2,4-D). Lomuthi wokubulala ukhula ubulokhu usetshenziswa kabanzi kusukela yethulwa ngawo-1940, ikakhulukazi ukulawula ukhula lwamaqabunga abanzi ezindaweni zokulima. Ukusebenza kahle kwayo kanye nezindleko eziphansi uma kuqhathaniswa kuyenza ibe ukudla okuyisisekelo kwezolimo, ikakhulukazi ekulinyweni kwezitshalo ezifana nommbila nokolweni.

I-2,4-D isebenza ngokulingisa ama-isomer ehomoni yezitshalo zemvelo aphazamisa amaphethini avamile okukhula ezitshalo ezizwelayo. Le ndlela yokusebenza ivumela ukukhomba okukhethiwe kanye nokucekelwa phansi kwezimila ezingafuneki kuyilapho kugcinwa isivuno ngaphandle kokulimala. Kodwa-ke, ukusetshenziswa kwe-2,4-D akukhona ukungqubuzana. Ukukhathazeka ngomthelela wayo kwezemvelo kanye nobungozi bezempilo obungaba khona kuye kwaholela amazwe amaningi ukuthi aqinise ukulawula nokulawula.

Eminyakeni yakamuva, ucwaningo lugxile ekuthuthukiseni ezinye izindlela eziphephile nezisebenza ngempumelelo ku-2,4-D, kanye nokuhlola indima yazo kumasu ahlanganisiwe okulawula izinambuzane. Ukuqonda izici nokusetshenziswa kwe-791-31-1 kubalulekile kochwepheshe bezolimo nososayensi bezemvelo njengoba bekwazi ukubhekana nobunzima bezinqubo zesimanje zezolimo.

Kafushane, i-791-31-1 noma i-2,4-D iyinhlanganisela ebalulekile enomlando ocebile kwezolimo. Ukusetshenziswa kwayo okuqhubekayo kanye nocwaningo oluqhubekayo oluzungezile kugcizelela ukulingana phakathi kokulawulwa kokhula okuphumelelayo nokuphathwa kwemvelo.
