Cadmium (Cd) is a well-known heavy metal that could cause environmental pollution, as well as, human and animal health problems. ABSTRACT. 12 0 obj Current Topics in Environmental Health and Preventive Medicine. Selenium (Se) plays important role in the protection of plants against various abiotic stresses, including heavy metals. Environmental exposure to cadmium has been particularly problematic in Japan where many people have consumed rice that was grown in cadmium-contaminated irrigation water. Occupational cohort studies have suggested possible associations between chronic exposure to cadmium, particularly cadmium oxide, and cancers of the lung, prostate, and genitourinary system such as renal carcinoma. An occupational study showed increased numbers of chromosomal aberrations in the lymphocytes of cadmium-exposed workers (NTP 2004). x�+�r 22 0 obj It affects the ubiquitin/ATP-dependent proteolytic pathway. Developing approaches for efficiently treating environmental Cd is a priority. Cadmium's toxicity primarily affects the lungs and kidneys, with secondary effects on the skeletal system. 378-399. Therefore, it is interesting to investigate whether some lactobacilli might play a role in the alleviation of acute cadmium toxicity. However, owing to the lack of investigation of the molecular mechanism of cadmium conjugating to transferrin, the role of transferrin in cadmium … Conversely, iron deficiency per se appears to limit the severity of the inflammatory response. This linkage is the reason cited by the IARC in 1993 for designating cadmium as a known human carcinogen and by the NTP for its characterization of cadmium as a known human carcinogen in 2000.
