Izinkomishi zamanzi zepulasitiki zithandwa abantu abaningi, ikakhulukazi izingane, intsha, kanye nabathandi bangaphandle, njengabamakhenikha bezolimo, izisebenzi zokwakha, nezisebenzi zokwakha, ngenxa yokuhlukahluka kwazo, imibala egqamile, amanani aphansi, kanye nemvelo engeyona intekenteke.Ochwepheshe bakhumbuza ukuthi ukusetshenziswa isikhathi eside kwezinkomishi zamanzi epulasitiki akuphephile emanzini okuphuza, futhi akukhuthazwa ukusebenzisa izinkomishi zamanzi zepulasitiki.Izizathu zimi kanje:
Okokuqala, amapulasitiki ayizinto ze-Polymer chemistry, ngokuvamile aqukethe amakhemikhali anobuthi njenge-polypropylene noma i-PVC.Amanzi okuphuza enkomishini yepulasitiki asetshenziselwa ukubamba amanzi ashisayo noma abilayo.Uma usebenzisa izinkomishi zamanzi zepulasitiki ukuze ubambe amanzi ashisayo, ikakhulukazi amanzi abilisiwe, amakhemikhali anobuthi epulasitiki angangena kalula emanzini.Ukuphuza amanzi anjalo isikhathi eside kuzodala umonakalo emzimbeni womuntu.
Okwesibili, izinkomishi zamanzi zepulasitiki zithambekele kumagciwane futhi akulula ukuzihlanza.Lokhu kungenxa yokuthi ipulasitiki ebonakala inobuso obushelelezi ayibushelelezi, futhi kunezimbotshana eziningi ezincane ku-microstructure yangaphakathi.Lezi zimbotshana ezincane zijwayele ukungcola nezikali, futhi azikwazi ukuhlanzwa kusetshenziswa izindlela ezijwayelekile.
Okwesithathu, izinkomishi eziningi zamanzi epulasitiki ezithengiswa emakethe zenziwe nge-polycarbonate, kanti i-bisphenol A ingenye yezinto eziphambili zokukhiqiza amapulasitiki e-polycarbonate.I-Bisphenol A yaziwa emhlabeni wonke njengento engandisa ingozi yomdlavuza, futhi ihlobene nomdlavuza webele, umdlavuza wendlala yesinye kanye nokuthomba ngaphambi kwesikhathi.Ukulimala kwayo emzimbeni womuntu kufana nokubhema.Ngemva kokungenisa, kunzima ukubola, kunomphumela wokuqongelela, futhi kungadluliselwa esizukulwaneni esilandelayo.Ngokokuhlola okwenziwa i-Harvard School of Public Health e-United States, ukuphuza iziphuzo emabhodleleni epulasitiki nokudla okugcinwe ezitsheni zepulasitiki kuyimithombo eyinhloko ye-bisphenol A emzimbeni womuntu.
