| Term (EN) | lethal concentration 50 LC50 |
|---|
| Definition (EN) | concentration (4.52) of a toxic gas (4.336) or fire effluent (4.105), statistically calculated from concentration-response data, that causes death of 50% of a population of a given species within a specified exposure time (4.90) and post-exposure time (4.254)
cf. effective concentration 50 (4.72)
NOTE 1 For fire effluent, typical units are grams per cubic metre (g⋅m-3).
NOTE 2 For a toxic gas, the typical units are microlitres per litre (μL/L) at T=298 K and P=1 atm; see volume fraction (4.351). |

| Definition (BS) | koncentracija (4.52) toksičnog gasa (4.336) ili produkata požara (4.105), statistički proračunata iz podataka vezanih za odnos koncentracija-odgovor, koja uzrokuje smrt 50% populacije date vrste u određenom vremenu izlaganja (4.254)

NAPOMENA 1 Za produkte požara tipične jedinice su grami po kubnom metru (g⋅m-3).
NAPOMENA 2 Za toksični gas tipične jedinice su mikrolitri po litru (μL/L) na T=298 K i P=1 atm; vidjeti zapreminski udio (4.351). |
