Arsenic, cadmium, lead, and mercury are toxic elements that are almost ubiquitously present
at low levels in the environment because of anthropogenic influences. Dietary intake of plant …

Plants absorb a number of elements from soil, some of which have no known biological
function and some are known to be toxic at low concentrations. As plants constitute the …

Natural processes and human activities have caused widespread background
contamination with non-essential toxic elements. The uptake and accumulation of cadmium …

The metalloid arsenic and the heavy metal cadmium have no demonstrated biological
function in plants. Both elements are highly toxic and of major concern with respect to their …

Over the past 200 years emissions of toxic heavy metals have risen tremendously and
significantly exceed those from natural sources for practically all metals. Uptake and …

Agricultural soils are under threat of toxic metal/metalloid contamination from anthropogenic
activities, leading to excessive accumulation of arsenic (As), cadmium (Cd), lead (Pb), and …

Arsenic (As) is an environmental and food chain contaminant. Excessive accumulation of As,
particularly inorganic arsenic (As i), in rice (Oryza sativa) poses a potential health risk to …

Arsenic (As), classified as a “metalloid” element, is well known for its carcinogenicity and
other toxic effects to humans. Arsenic exposure in plants results in the alteration of the …

Abstract Arsenic (As), a naturally-occurring metalloid, is not essential for plant growth, but it
can accumulate in plants to toxic levels. As a result, it can enter the food chain and pose …

Iron, zinc, copper and manganese are essential metals for cellular enzyme functions while
cadmium, mercury and the metalloid arsenic lack any biological function. Both, essential …
