in unaffected fresh air Planta simulando o ambiente do Carbonífero,onde havia 35% de oxigênio e 4000 ppm de co2. Esses pés de milho de pipoca foram tratados com 30% de oxigênio e 4 I et klasselokale med lukkede døre og vinduer og uden ventilation, stiger CO2 niveauet til over 1000 ppm på ca. 30 min. Når CO2 niveauet er 1000 ppm eller højere, begynder det at påvirke hjernen negativt. Det betyder at evnen til at koncentrere sig nedsættes markant, desuden giver det fysisk ubehag som hovedpine og træthed.

Inlägg av Jocke_999 » 2010-12-13 10:02:16 Peter Nyman skriver ju så här på sin hemsida "Vattnets koldioxidhalt är hårt förknippat med dess KH och pH-värde (så länge man inte tillsatt torv eller andra buffrande ämnen i vattnet)." 10 ppm of non carb KH is not enough to cause a huge difference. 2-3 degrees or more, certainly is, and as you get higher up, that difference only increases, so you might think at a KH of your CO2 ppm is 50 ppm, when it's actually 30ppm.

However, that toxicity threshold can change drastically, depending on the levels of dissolved oxygen in the water. In tanks where the levels of oxygen are low, the fish are more sensitive to the toxic effects of CO2. Carbon dioxide (CO2) sensors and monitoring devices are offered in many different ranges, from 0 ppm (parts per million) to 100% CO2. Selecting the sensor or monitor with the correct range of CO2 to be measured for your application is important. Learn More About Atmospheric CO2 Readings & Stabilization.

Formula: concentration (mg/m 3) = 0.0409 x concentration (ppm) x molecular weight For example: 100 ppm of NH 3 (17.03 g/mol) 0.0409 x 100 ppm x 17.03 = 69.652 Se hela listan på climate.gov Concentration percentage unit conversion between part per million and gram/kilogram, gram/kilogram to part per million conversion in batch, ppm g/kg conversion chart Nivåerna av CO2 i dag är även de på en historiskt låg nivå för 20 000 år sedan när den senaste istiden började gå mot sitt slut var CO2 halten 180 ppm vilket endast är 30 ppm över den nivå som växtligheten klarar.

Carbon Monoxide Meters Most fish and invertebrate species can live comfortably and safely in water that has a CO2 content of 30 ppm (mg/l). However, that toxicity threshold can change drastically, depending on the levels of dissolved oxygen in the water. In tanks where the levels of oxygen are low, the fish are more sensitive to the toxic effects of CO2. Carbon dioxide (CO2) sensors and monitoring devices are offered in many different ranges, from 0 ppm (parts per million) to 100% CO2.
