Effectsof cd toxicity are It brings about the denaturation of proteins, inhibitsbacterial respiration and proton–solute cotransport, and causes single-strandedbreaks in cellular DNA (Cunningham and Lundie 1993; Jungmann etal. 1993; Mitra and Bernstein 1978)  Because of the bioaccumulation ofCd and its long-term toxicity in humans, the study of Cd sequestration bymicroorganisms to clean Cd-contaminated environments becomes important. CADMIUM POISONINGCadmium has differentuses in various industries and in different form including vapour lamps, duringelectroplating, storage batteries and in some solders. Overexposure may causedifferent effect on health of the individual who come in contact with thiswhich includes headache, vomiting, fatigue, abdominal cramps, diarrhea, and fever.It can also cause pulmonary edema and dyspnea.(ATSDR).

It may cause teeth  yellowing ,unusual rapid heartbeat, irondeficiency in RBC. From where does Cd come? Cadmiumis usually present in ores of zinc and greenockite cadmium mineral (lesspercentage). Cadmium is present in effluent produced from textile industrieswhere it is used due to its ability to produce orange, yellow and red colour.

Cadmium is also present in discard of nuclear reactors where it acts as aneutron absorber. How Cd affects mankindWorkers have exposure duringrefining of metals, smelting batteries manufacturing, plastics coatings, andsolar panels. The expanding Ni-Cd battery recycling industry is a concern forcadmium exposure. Electroplating, metal machining, welding and painting areoperations associated with cadmium exposure. Workers involved in landfilloperations, the recycling of electronic parts, or the recycling of plastics maybe exposed to cadmium. Compost workers and waste collectors are alsopotentially exposed to dust which may contain cadmium.

The incineration ofmunicipal waste is another source of cadmium exposure.
