Overview"Nitroaromaticheskie soedineniya, shiroko ispol'zuemye v kachestve vzryvchatykh veshchestv i pestitsidov, sostavlyayut gruppu vazhnykh ekologicheski opasnykh zagryazniteley. Toksichnost' trinitrotoluola (TNT) i ego metabolitov pokazana v razlichnykh test-sistemakh, ot kletok bakteriy do mlekopitayushchikh. Naibolee rasprostranyennym putyem transformatsii dannogo soedineniya v aerobnykh usloviyakh yavlyaetsya posledovatel'nyy dvukhelektronnyy vosstanovitel'nyy mekhanizm, privodyashchiy k prevrashcheniyu nitrogruppy v aminogruppu. Polnaya vosstanovitel'naya transformatsiya TNT do triaminotoluola vyyavlena tol'ko u strogo anaerobnykh mikroorganizmov.
