Sezvakamboita FAQ, nyaya chaiye haisi iyo inoshandiswa kuisa ruvara, asi huni, pachayo - dzimwe dzingangodaro dzine arsenic mairi. Kunyange zvazvo tichiziva kuti arsenic inogona kukuvadza vanhu, unogona kuzvibvunza kuti chii chinogona kuita kuti ivhu rinenge riri guru pane rinowanzosangana ne arsenic (kuburikidza nematombo ane mavara akasiyana-siyana akawanikwa kubva kuCCA-vakatora huni) inogona kuva nehutano hwakanaka.
Handisi musayendisiti, saka ndinongotaura pano kuti pakuverenga kwangu pamusoro pehurukuro, handina kuonana zvakawanda izvo zvingaratidza kuti "chinyorwa chisingazivikanwi" chinyorwa chemavara chingave chinokuvadza kumiti yakapoteredza. Speir et al. (1992) yakaitisa zvidzidzo zviviri zvakafanana pamusoro pe "zvinokonzerwa nevhu rebiochemical uye zvipenyu zvevhu rakachinjwa neCu-, Cr- uye As- (CCA) -revedzwa,
- "mienzaniso yevhu yakaongororwa mushure mokunge muedzo wekuita wakaitwa kuti uongorore migumisiro yezvigadziriswa pakukura kwezvirimwa uye chinhu chinowedzera"
- "kushandiswa kwekudzidzira kushandiswa pasina michero uye nemidziyo yevhu inotorwa kuti iongororwe"
Zvigumisiro, maererano nezvakanyorwa, "kurongedza kubvumirwa kweuchenjeri kweCACA-treated treateddust as a mulch or garden amendment." Ona nyaya yangu yakasiyana paCCA-Treated Wood kuti udzidze zvakawanda nezvayo.

My FAQ inotaura zvakananga nezvenyaya yemavara machena uye utano hwemiti. Zvisinei, sezvo isu tiri ivo vanobata sungiriro, zvinetso zvehutano hwevanhu zvichiri kukosha.
Nokuda kwekukakavadzana, ngatitii mavara asina kujeka ane mavara haana kuipa kumiti. Saka tinofanira kuishandisa here? Zvisarudzo zvedu zviri pakati:
- Chimwe chinyorwa chisingazivikanwi chine mavara, chine chimiro chaicho chisingazivikanwi uye kuti kunyorwa kwacho kwakakwana hakugoni kujekeswa pasina chidimbu mumakemiti.
- MSC-yakavhenekera mutsvuku wematombo, chibereko chatinoziva zvishoma nezvako
- Kana kuti mashizha echisikigo, akadai sebhuna risina kuvezwa, uswa, uswa, kana mashizha atakanga tava kukwira mukuwa .
Tinoziva kuti mashizha echisikigo haabvumi kukuvadza - kana kwatiri kana kumiti yedu. Chisarudzo chechipiri chakanaka chinoratidzika kwandiri kuti ndicho MSC-yakagadziridzwa yemarch mulch. Asi iwe chete unogona kusarudza kuti ndeipi nzira yakarurama yekuita iwe.
