Bioaccessibility And Health Risk Of Arsenic And Heavy

7 hours ago The bioaccessibility and human health risks of As and heavy metals (Cu, Pb, Zn, Ni, Co, Cr, Cd and Mn) in total suspended particulates (TSP) and fine particulate matter (PM2.5) in Nanjing, China were investigated. The average mass concentration ratios of PM2.5 to TSP were 0.61 for Gulou sampling site and 0.50 for Pukou sampling site, respectively.

Frequently Asked Questions

What are the health risks of arsenic and heavy metals?

Health risk of arsenic and heavy metals via ingestion exposure Airborne particles may deposit on food, drinks and surfaces of outdoor and indoor appliances and result in health risks to the residents.

What is the difference between arsenic bioavailability and as bioaccessibility?

Arsenic bioavailability was determined using an in vivo mouse model, and As bioaccessibility was determined using the Solubility/Bioavailability Research Consortium in vitro assay.

How can we improve the accuracy of risk estimates of arsenic toxicity?

Moreover, conducting risk studies based on age groups and correcting for bioavailability of arsenic, cadmium, lead, and mercury enhance accuracy of risk estimates.

What is the population based risk assessment of arsenic and calcium toxicity?

Thirdly, population-based risk assessment of arsenic, calcium, lead, and mercury should be carried out to estimate the likelihood of adverse effect to vulnerable age groups, such as the elderly and children, in endemic areas such as mining areas.
