Qhov cuam tshuam ntawm cov dej hauv lub raj mis rau cov peev txheej ntuj yog 3,500 npaug ntau dua li cov dej kais dej, cov kws tshawb fawb tau pom.
The research is the first of its kind and examined the impact of bottled water in Barcelona, where it is becoming increasingly popular despite improvements to the quality of tap water in recent years.
Research led by the Barcelona Institute for Global Health (ISGlobal) found that if the city's population were all to drink bottled water, this would result in a 3,500 times higher cost of resource extraction than if they all drank tap water, at 83.9m (£60.3m)a year.
Cov kws tshawb fawb tseem pom qhov cuam tshuam ntawm cov dej hauv lub raj mis ntawm cov ecosystem yog 1,400 npaug siab dua li cov dej kais dej.
Cov kws sau ntawv xaus lus tias kev txo qis hauv ib puag ncig cuam tshuam ntau dua li kev pheej hmoo me me ntawm qog nqaij hlav qog noj ntshav cuam tshuam nrog kev haus dej haus. Cov txheej txheem ntawm kev kho cov dej haus ua rau qis qis ntawm trihalomethanes (THM), uas tau cuam tshuam nrog kev pheej hmoo siab ntawm lub zais zis. THM qib hauv cov dej haus tau tswj hwm hauv EU.
Tus thawj coj ntawm txoj kev tshawb no, tus kws tshawb fawb ISGlobal Cristina Villanueva, tau hais tias: "Cov laj thawj kev noj qab haus huv tsis zoo rau kev siv dej fwj dav. Koj tau txais los ntawm kev haus dej hauv lub raj mis tsawg heev, nws pom tseeb tias qhov cuam tshuam ib puag ncig ntawm cov dej hauv lub raj mis siab dua piv rau cov dej siv. "
In the US, 17m barrels of oil are needed to produce the plastic to meet annual bottled water demand. In addition, bottled water in the UK is at least 500 times more expensive than tap water.
Villanueva tau hais ntxiv tias: "Kuv xav tias txoj kev tshawb fawb no tuaj yeem pab txo qis kev haus dej hauv lub raj mis, tab sis peb xav tau cov cai tswjfwm ntxiv los hloov qhov ntawd.
"Piv txwv li, hauv Barcelona, peb tuaj yeem muaj kev tshaj tawm kev kawm ntau ntxiv los ua kom cov pej xeem paub tias kev noj qab haus huv tau los ntawm cov dej haus hauv lub raj mis yog qhov me me piv rau ib puag ncig cuam tshuam. qhov twg koj tuaj yeem nqa koj lub raj mis thiab tsis tas yuav yuav ib qho.
"Tib neeg tso siab rau cov dej hauv lub raj mis vim tias cov neeg tshaj tawm tau ua txoj haujlwm zoo ntawm kev ntxias tib neeg nws yog qhov kev xaiv zoo, yog li peb xav tau kev siv zog ntawm lwm sab."
