Eco-dehwe chigadzirwa chematehwe chine zviratidzi zve ecological zvinosangana nezvinodiwa zveecological zviyero. Idehwe rekugadzira rakagadzirwa nekupwanya tsvina yematehwe, zvimedu nematehwe akaraswa, uyezve kuwedzera zvinonamira nekutsikirira. Iyo ndeyechizvarwa chechitatu chezvigadzirwa. Eco-dehwe rinoda kuzadzisa zviyero zvakatarwa nehurumende, zvinosanganisira zvinhu zvina: yemahara formaldehyde, hexavalent chromium yemukati, yakarambidzwa azo dhayi uye pentachlorophenol zvirimo. 1. Formaldehyde Yemahara: Kana ikasabviswa zvachose, ichakonzera kukuvadza kukuru kumasero evanhu uye kunyange kukonzera kenza. Iyo chiyero ndeichi: zvirimo zviri pasi pe75ppm. 2. Hexavalent chromium: Chromium inogona kuita kuti dehwe ripfave uye rakapfava. Iripo mumhando mbiri: trivalent chromium uye hexavalent chromium. Trivalent chromium haina ngozi. Yakawandisa hexavalent chromium inogona kukuvadza ropa remunhu. Zviri mukati zvinofanirwa kunge zviri pasi pe3ppm, uye TeCP iri pasi pe0.5ppm. 3. Yakarambidzwa azo dyes: Azo idhayi yekugadzira inobudisa amines inonhuhwirira mushure mekubatana neganda, iyo inokonzera kenza, saka iyi dhayi yekugadzira inorambidzwa. 4. Pentachlorophenol content: Inochengetedza yakakosha, ine chepfu, uye inogona kukonzera kuremara kwebiological uye cancer. Zviri mukati mechinhu ichi muzvigadzirwa zvematehwe zvinotemerwa kuve 5ppm, uye iyo yakanyanya kuomesesa chiyero ndechekuti zvirimo zvinongove zvakaderera pane 0.5ppm.
