Cadmium (Jeremy Willett)
Cadmium is a soft, bluish-white metal that was first discovered in 1817 by German chemist Friedrich Strohmeyer while studying calamine. It has several important industrial uses including in nickel-cadmium batteries, as an anti-corrosive coating for steel, and in semiconductors. However, cadmium is also toxic to humans and accumulates primarily in the kidneys, where high levels can lead to kidney failure. While cadmium intake has decreased in recent decades, it remains a concern due to negative health effects. Cadmium is obtained as a byproduct during production of other metals like zinc, copper and lead.
Cadmium in Rice_2013
Cadmium is a naturally occurring metal that can contaminate rice plants through soil and water. It does not break down in the environment. While acute cadmium toxicity from food is unlikely, long term intake of excessive amounts can impact the kidneys. Dietary exposure is currently the main source of cadmium for most people. A risk assessment found the general population unlikely to experience health issues from dietary cadmium levels in Hong Kong. Standards for cadmium in rice have been set by Mainland China, the EU and Hong Kong to limit human exposure.

Cyclophosphamide ppt
Cyclophosphamide is an alkylating agent used to treat white blood cell cancers and lymphoma. It works by being metabolized into phosphoramide mustard, which adds alkyl groups to DNA, forming crosslinks between and within DNA strands. This leads to DNA damage and ultimately cell death. The expression of genes coding for enzymes involved in cyclophosphamide metabolism, such as cytochrome P450 and ALDH, can affect how sensitive cancer cells are to the drug.
Effect Of Exposure To Lead And Cadmium In Drinking Water Sources From Nigeria...
As Nigeria strives towards attaining the Millennium Development Goal for water, this study was
carried out to investigate the effect of exposure to lead (Pd) and cadmium (Cd) in drinking water source in the
Niger Delta region on fecundity and reproductive organ weights. Prior to the study, levels of heavy metals in
samples were assessed and compared to WHO permissible limit. The levels of Pb and Cd were higher than that
of WHO limit in some samples selected and used for the study. WHO permissible limit of lead and cadmium in
the drinking water are 0.01 and 0 003mg/L respectively. Forty eight albino Wistar rats (210-240g) of both
sexes were assigned into three groups: control (16), Pb-treated (16) and Cd-treated (16). The control group was
given distilled water, while the Pd-treated and Cd-treated group were administered drinking water randomly
collected from natural source with Pd (0.00-0.142mg/L) and Cd (0.00-0.024mg/L/) .All water was administered
in drinking water bottles filled with nozzles for a 28-day period. Male and female rats of each group were then
mated as follows: control males versus control females, control males versus Pb-treated females, Pb-treated
males versus control females and Pb-treated males versus Pb-treated females. The same procedure was
followed for Cd, Gestation day zero was regarded as day spermatozoa were identified in vaginal smear of
female rats. Pregnant animals were separated and the pregnancy allowed to come to term. Litter size and
morphological appearance of litters from each group and reproductive organ weight were noted. The litter size
of group 1 (control) for Pb and Cd was 12; group 11 was 8 and 6 respectively; group 111 was 5 and 2
respectively; while group IV showed no reproductive outcome. The results suggest adverse effect of Pb and Cd
in drinking water on fecundity of albino Wistar rats

Neurobehavioural, neurochemical and neuromorphological effects of cadmium in ...
This study evaluated the neurobehavioral, neurochemical, and histopathological effects of cadmium chloride in male rats. 45 male rats were divided into 3 groups - a control group and 2 groups exposed to low-dose (5mg/L) and high-dose (50mg/L) cadmium chloride in drinking water for 60 days. Behavioral tests showed increased activity and decreased memory in exposed groups. Biochemical analysis found decreased acetylcholinesterase and increased lipid peroxidation in brains of exposed rats. Histopathological examination found neurodegeneration in brains of exposed rats. The study suggests that cadmium exposure can cause neurological damage and behavioral impairments due to oxidative stress.

Hazardous waste management copy
Cadmium is a toxic heavy metal that is hazardous as a waste product. It is generated from mining and smelting/refining of zinc, lead, and copper ores. Cadmium waste can be flammable, reactive, carcinogenic, and toxic. Treatment methods for cadmium waste include ion exchange, sulphide precipitation, cementation, electrocoagulation, and adsorption to reduce cadmium levels in liquid wastes. Processed cadmium waste is then disposed of through landfills, surface impoundments, waste piles, injection wells, salt bed formations, or underground mines.
