Pamene mukuyenda panyanja, tizilombo toyambitsa matenda tikhoza kusangalala ndi madzi pambali panu. Inde, mabungwe a zaumoyo akuyesetsa kuyesa chitetezo cha madzi anu osambira, koma izi sizikutsimikizira kuti gombe lanu lidzatsekedwa mphindi zochepa zomwe mabakiteriya akuwonetsa kuti awononge chisangalalo.

"Zimatenga nthawi kuyesa mayeso amadzi, ndipo sitimayesa tsiku lililonse," akufotokoza a Jon Devine, loya wamkulu wa Natural Resource Defense Council (NRDC), yemwe amayang'anira madzi anu ngati mumakhala mbali iliyonse ya m'mphepete mwa nyanja, Gulf, kapena imodzi mwa Nyanja Yaikulu. Devine akuti palinso mikangano pakati pa asayansi pa zomwe zimapanga mabakiteriya "otetezeka".

Chifukwa chiyani muyenera kuda nkhawa ndi izi? Gunk (yomwe nthawi zambiri imawoneka) yomwe ikuyandama m'madzi anu imatha kuyambitsa chilichonse kuyambira diso la pinki ndi chimfine cha m'mimba mpaka hepatitis ndi meningitis, atero a Devine. Ngakhale mchenga ndi wotetezeka: Kafukufuku waposachedwapa mu American Journal of Epidemiology adapeza oyenda kunyanja omwe adakumba mumchenga amatha kudwala. Olembawo akuti mchenga umayamwa zowonongera zomwezi zomwe madzi amatenga. Koma mosiyana ndi madzi, mchenga umalowedwa m'malo ndi mvula yatsopano kapena kutsukidwa ndi mitsinje. (Ndiye tulukani ma sandcastles?)

Kuti mudziteteze ku kuipitsidwa, Devine akulangiza kuti mupite ku malo a NRDC, komwe mungayang'ane malipoti amadzi a gombe lomwe mumakonda. "Izi zikupatsani chithunzithunzi cha momwe madzi anu anali kuwonekera kale," akutero. Mwayi ndi wabwino ngati madzi ali onyansa, momwemonso mchenga, phunziro lomwe lili pamwambapa likusonyeza.

Koma simufunikira chemistry kuti ikuuzeni ngati kumenya mafunde sikulakwa. Nazi zizindikiro zisanu kuti gombe lanu ndi nkhani zoipa.

1. Kungogwa. Kuthamanga kwamadzi amkuntho ndi chimodzi mwazomwe zimayambitsa kuipitsa madzi, Devine akuti. Ngati mvula yamabingu yayikulu idumpha dera lanu, kusakhala m'madzi kwa maola osachepera 24 ndi lingaliro labwino, akulangiza, ndikuwonjezera kuti, "Maola makumi asanu ndi awiri mphambu awiri ndiabwino."

2. Iwe ukuwona imvi. Yang'anani kuzungulira gombe lanu. Ngati muwona malo oimikapo magalimoto ambiri, misewu yowaka, ndi zinthu zina za konkriti, ndiye vuto, akufotokoza motero Devine. Chifukwa dothi limakhala ngati siponji yamadzi achilengedwe komanso zosefera, zimathandiza kuti madzi onyansa asathamange kumalo osambira omwe mumakonda. Konkriti ndi zomangidwa ndi anthu zimakonda kuchita zosiyana, akutero a Devine.

3. Mutha kugwedeza kwa ogwira ntchito panyanja. A Devine akuti mabwato amatulutsa zinthu zamtundu uliwonse, kuyambira zimbudzi zoyambira mpaka mafuta. Komanso, ma marinas amakonda kukhala m'malo odekha, otetezedwa, momwe madzi omwewo amatha masiku ambiri, akusonkhanitsa zowononga. Kusambira m'madzi otseguka, omwe amakhala ozizira komanso owaza, ndi lingaliro labwino, akuwonjezera Devine.

4. Mipope ilipo. Mizinda yambiri ndi matauni ali ndi makina osungira madzi omwe amatulutsira chilichonse koma zimbudzi m'madzi am'deralo, a Devine akufotokoza. Ingoyang'anani mapaipi, omwe amathamangira mpaka (kapena ngakhale kulowa) pagombe asanawonongeke mobisa, akutero.

5. Mukugundana ndi osambira ena.Anthu ndi onyansa. Ndipo mukamawona ambiri akuzungulirani m'madzi, mumakumana ndi mabakiteriya okhudzana ndi matenda chifukwa cha "kusamba," akufotokoza a Liz Purchia, mneneri wa EPA.
