2021-2-23  One example of the exposure infants can face is a brand of carrot baby food found to have 23.5 parts of lead per billion, equivalent to 0.67 micrograms of lead per ounce. Since the average 6-month-old eats 4 ounces of vegetables a day, that would be 2.7 micrograms of lead a day almost the maximum tolerable daily dose.

Effects of sample processing on arsenic speciation in

The stability of arsenic species in environmental samples during sampling, storage and processing is crucial for speciation studies. Losses, interconversion and degradation of arsenocompounds can

Analysis of arsenic species accumulation by plants and

Since these plants bear such high arsenic quantities, they must have a strategy for detoxification. 10. Very little is known about the processing of arsenic within the plant or tolerance mechanisms in view of high arsenic contents in the soil. Furthermore, no concrete data exists concerning the effect of arsenic on the metabolism of plants.

Arsenic Transport, Metabolism and Toxicity in Plants

2016-10-31  Arsenic is a toxic metalloid present in large areas in some parts of world including densely populated areas of Bangladesh and West Bengal, India. Being a carcinogenic metalloid, it affects the health of millions of people of affected areas through drinking water and food. Nonetheless, the spread of arsenic contamination reaches to non-affected areas also.

Rice consumption is a source of arsenic (As) exposure, which poses serious health risks. In this study, the accumulation of As in rice was studied. Research shows that As accumulation in rice in Taiwan and Bangladesh is higher than that in other countries. In addition, the critical factors influencing the uptake of As into rice crops are defined.
