Kodi eco-chikopa ndi chiyani?

Eco-chikopa ndi chinthu chachikopa chomwe zizindikiro za chilengedwe zimakwaniritsa zofunikira za chilengedwe. Ndi chikopa chopanga chopangidwa ndi kuphwanya zikopa zinyalala, zinyalala ndi zikopa zotayidwa, ndiyeno kuwonjezera zomatira ndi kukanikiza. Ndi m'badwo wachitatu wa mankhwala. Chikopa cha Eco chikuyenera kukwaniritsa miyezo yomwe boma limapereka, kuphatikizapo zinthu zinayi: formaldehyde yaulere, chromium ya hexavalent, utoto woletsedwa wa azo ndi pentachlorophenol. 1. Formaldehyde yaulere: Ikapanda kuchotsedwa kwathunthu, imawononga kwambiri maselo amunthu ndipo imatha kuyambitsa khansa. Muyezo ndi: zomwe zili ndi zosakwana 75ppm. 2. Hexavalent chromium: Chromium imatha kupanga chikopa chofewa komanso chotanuka. Imapezeka m'mitundu iwiri: trivalent chromium ndi hexavalent chromium. Trivalent chromium ndi yopanda vuto. Kuchulukirachulukira kwa chromium kumatha kuwononga magazi amunthu. Zomwe zili mkati ziyenera kukhala zosakwana 3ppm, ndipo TeCP ndi yocheperapo 0.5ppm. 3. Mitundu ya azo yoletsedwa: Azo ndi utoto wopangidwa womwe umatulutsa ma amine onunkhira pambuyo pokhudzana ndi khungu, zomwe zimayambitsa khansa, kotero utoto wopangidwa ndi woletsedwawu ndi woletsedwa. 4. Pentachlorophenol zili: Ndi zofunika kuteteza, poizoni, ndipo angayambitse biological chilema ndi khansa. Zomwe zili muzinthu zachikopa zimanenedwa kukhala 5ppm, ndipo muyeso wokhwima kwambiri ndikuti zomwe zili muzinthuzo zitha kukhala zochepa kuposa 0.5ppm.
