Isingeniso sokusetshenziswa komkhiqizo

I-Copper sulfate (CuSO₄) iyinhlanganisela ye-inorganic. Isixazululo saso esinamanzi siluhlaza okwesibhakabhaka futhi sine-asidi ebuthakathaka. Isixazululo se-Copper sulfate sinezinto ezinamandla ezibulala amagciwane futhi sivame ukusetshenziselwa ukugeza izinhlanzi, ukubulala amagciwane ezintweni zokudoba (njengezindawo zokudla), kanye ne-p...

Ezolimo zasemanzini, igama elithi “ukukhipha ubuthi emzimbeni” laziwa kakhulu: ukukhipha ubuthi ngemva kokushintsha kwesimo sezulu kungazelelwe, ukusetshenziswa kwezibulala-zinambuzane, ukufa kwe-algal, ukufa kwezinhlanzi, ngisho nokudliswa ngokweqile. Kodwa isho ukuthini ngempela elithi “toxin”? Iyini "Toxin"?...
