This document discusses the electrochemical series of metals. It begins by explaining that the standard hydrogen electrode, with a potential of 0 V, is used as the reference electrode. Metals are arranged in the series based on their standard electrode potentials relative to hydrogen - the more positive the potential, the stronger the metal is as an oxidizing agent and the more easily it gains electrons. Metals on the left side of hydrogen in the series can reduce hydrogen ions to elemental hydrogen, displacing hydrogen from acids. A metal higher in the series can displace from solution all metals appearing to its right.

2. • GAS BEZ BOJE, UKUSA I MIRISA- SILENT KILLER
• DRUGI PO REDU UZROK NEMEDIKAMENTNIH TROVANJA
• OSLOBAĐA SE PRI NEPOTPUNOM SAGORJEVANJU
3. • MEHANIZAM TOKSIČNOSTI- VEZUJE SE ZA HEMOGLOBIN
TAČNO NA MJESTO NA KOJE SE VEZUJE KISEONIK I TAKO
NASTAJE KARBOKSIHEMOGLOBIN
• 200 PUTA VEĆI AFINITET ZA HEMOGLOBIN OD KISEONIKA
• TAKAV HEMOGLOBIN NE MOŽE DA VEŽE ZA SEBE KISEONIK I
NASTAJE HIPOKSIJA U ORGANIZMU
4.
5. AKUTNO TROVANJE
• OŠTEĆENJE SRCA I MOZGA
• 10-20% HBCO - SLABI I NEJASNI, NESPECIFIČNI ZNACI
• 30-50% HBCO - JAKA GLAVOBOLJA, KONFUZIJA, POREMEĆAJ
RAZMIŠLJANJA, KOLAPS... POVEĆAN INTRAKRANIJALNI PRITISAK...
• SMRT – MIOKARDIJALNA ISHEMIJA
• POREMEĆAJI U EEG-U, NEUROPATIJA I DEMIJELINIZACIJA NERAVA;
• CRVENIJA KRV!
6. HRONIČNO TROVANJE
• 2,5% HBCO - BLAGI SIMPTOMI
• 5% HBCO – SLABLJENJE PSIHOMOTORNIH FUNKCIJA
• KARDIOVASKULARNE PROMJENE – ČAK I ANGINA
PECTORIS
9. CO2- UGLJEN DIOKSID
• GAS BEZ BOJE I MIRISA, NAKISELOG UKUSA
• NORMALAN SADRŽAJ U ATMOSFERI 0,03-0,04% (MAX.
0,1% U ZATVORENIM PROSTORIJAMA);
• ZAGUŠLJIVE PROSTORIJE GDE SE LOŽI I PUŠI – SADRŽAJ
CO2 OD 0,1% - 10% (OBIČNO 0,5%);
• RUDNICI, BUNARI, UVALINE, PODRUMI GDE ZRI VOĆE
...(40%) – TRENUTNA SMRT...
10. • GAS STAKLENE BAŠTE GLOBALNO ZAGRIJAVANJE
• ONEMOGUĆAVA ORGANIZAM DA DOBIJE DOVOLJNO
