Contamination can also occur with the use of water and / or food, causing irritability, tremors, distortion of vision and hearing, memory problems, lungs, nausea, vomiting, diarrhea, increased blood pressure, eye irritation, pneumonia, chest pain, cough. In drinking water for small amounts of metals which do not cause problems to the health of living beings, but they can accumulate over time, especially mercury and cadmium, which may be in the body of aquatic organisms in high quantity. The amalgam used in fillings can infect humans? Lead is most commonly used in car batteries to provide power to start the engine, but the lead ions in the reactant substances are transformed during the recharging process that occurs after their operation. The lead contamination in used car batteries may occur during recycling of the batteries if they are not maintained the necessary care. When in excess in the body, lead into tissues, depositing bones, replacing calcium ions may occur in the elderly and the sick "dissolution" of the bones (osteoporosis). Cadmium is widely used in rechargeable nickel-cadmium- mio (nicad) for the operation of calculators, cell phones and other devices. When this cell is burned, its gases end up in the atmosphere but we inhale small amounts of cadmium coming by air. Most cadmium comes from our diet as for example potato, wheat, rice and other cereals. Cadmium excess in our body accumulates in the kidneys and liver and can cause chronic kidney disease. Heavy metals end up being retained in the upper soil layer, and also accessible to plant roots, therefore, participating in our metabolism. The consumption of batteries has grown with the development of new electronic devices. ACTIVITY Look in trade types of batteries available to consumers register their chemical composition. Interview a dentist and know the types and the fate of amalgam and resin used. Invite a colleague to discuss the use and destination of each type of cell found, record the result of discussions and propose action to reduce such waste in household waste.

Kontaminacija može dogoditi uz korištenje vode i / ili hrane, što uzrokuje razdražljivost, drhtanje, izobličenja vida i sluha, problema s pamćenjem, pluća, mučnina, povraćanje, proljev, povišen krvni tlak, iritaciju očiju, upala pluća, bolovi u prsnom košu, kašalj. U pitke vode za male količine metala koji ne uzrokuju probleme za zdravlje živih bića, ali oni mogu akumulirati tijekom vremena, osobito živu i kadmij, koja može biti u tijelu vodenih organizama u velikoj količini. Amalgam koristi u nadjevima može zaraziti i ljude? Olovo se najčešće koristi u akumulatori dati snage za pokretanje motora, ali vodstvo iona u reaktanata tvari pretvaraju se tijekom punjenja proces koji se javlja nakon operacije. Olovo zagađeno koriste akumulatori mogu pojaviti tijekom recikliranje baterija, ako se ne održava potrebnu njegu. Kada se u višak u tijelu, dovode u tkiva, odlaganje kosti, zamjena iona kalcija može pojaviti u starijih i bolesnih "raspada" od kostiju (osteoporoza). Kadmij je naširoko koristi punjive nikal-kadmij- mio (NiCad) za rad računala, mobitela i drugih uređaja. Kada se ova stanica je izgorjela, njegovi plinovi završiti u atmosferi, ali udišemo male količine kadmija koji dolaze zrakoplovom. Većina kadmij dolazi iz naše prehrane, kao primjerice krumpira, pšenice, riže i drugih žitarica. Kadmij višak u našem tijelu akumulira u bubrege i jetru, a može dovesti do kronične bolesti bubrega. Teški metali završiti zadržan u gornji sloj tla, a također dostupna korijenju biljaka, dakle, sudjeluju u našem metabolizmu. Potrošnja baterije je narasla s razvojem novih elektroničkih uređaja. AKTIVNOST Pogledajte u trgovini vrste baterija dostupnih potrošačima registriraju svoj kemijski sastav. Intervju stomatologa i znati vrste i sudbinu amalgama i smola koristi. Pozovi kolegu da raspravljaju o uporabi i odredište svakog tipa stanica nalazi, zabilježiti rezultat rasprave i predložiti mjere za smanjenje takav otpad u kućni otpad.
