The element barium imadziwika kuti ndi poizoni, koma barium sulfate wake wapawiri amatha kukhala ngati chosiyana ndi ma sikani awa.Zatsimikiziridwa ndi zamankhwala kuti ayoni a barium mu mchere amasokoneza kagayidwe ka calcium ndi potaziyamu m'thupi, zomwe zimayambitsa mavuto monga kufooka kwa minofu, kupuma movutikira, kusakhazikika kwamtima komanso ngakhale kufa ziwalo.Ichi ndichifukwa chake anthu ambiri amaganiza kuti barium ndi chinthu chodziwika bwino, ndipo anthu ambiri omwe ali pa barium carbonate amangokhala ngati poizoni wamphamvu wa makoswe.
Komabe,barium carbonateali ndi zotsatira za kusungunuka kochepa komwe sikungatheke.Barium carbonate ndi sing'anga yosasungunuka ndipo imatha kumezedwa kwathunthu m'mimba ndi matumbo.Zimagwira ntchito yofunikira mu maphunziro a m'mimba monga chosiyanitsa.Sindikudziwa ngati mwawerengapo nkhani imodzi.Nkhaniyi ikufotokoza za momwe mwala wa barium udasangalatsa mfiti ndi alchemist koyambirira kwa zaka za zana la 17.Wasayansi Giulio Cesare Lagalla, yemwe adawona thanthwelo, adakhalabe wokayikira.Chodabwitsa n'chakuti chiyambi cha zochitikazo sichinafotokozedwe momveka bwino mpaka chaka chatha (zisanachitike, zidanenedwa molakwika ndi chigawo china cha mwala).
Mankhwala a Barium ali ndi phindu lenileni m'malo ena ambiri, monga zolemetsa kuti madzi akubowola omwe amagwiritsidwa ntchito mumafuta ndi gasi Wells azikhala wandiweyani.Izi zikugwirizana ndi chikhalidwe cha dzina 56: barys amatanthauza "kulemera" mu Chigriki.Komabe, ilinso ndi mbali yojambula: barium chloride ndi nitrite amagwiritsidwa ntchito kupenta zozimitsa moto zobiriwira zobiriwira, ndipo barium dihydroxide imagwiritsidwa ntchito kubwezeretsa zojambulajambula.
