Lezi zicelo zamakhemikhali zivelise izinkinga ezingamashumi eminyaka zemvelo, futhi ziyavunywa ukuthi zinobungozi nakwezempilo yabantu. Kepha iqiniso lokuthi anobungozi kanjani la makhemikhali; nokuthi yimaphi amazinga okubekezelelana abantu abangamelana nawo ngokuphepha ekudalweni kokudla, kwamanzi nomoya kuvame ukuba nzima ukuthola. Abalawuli bathembele kakhulu ezifundweni zesayensi ezixhaswe futhi ziqondiswe izinkampani zezolimo ezithengisa amakhemikhali ukwahlulela ukuphepha kwazo, futhi imali namathuba okuhlaziya okuzimele kunqunyelwe.
