Arsenic exposure produces non-cancer effects that affect health. Cardiovascular illness due to arsenic exposure has been well documented, but little is known about arsenic in cardiovascular tissues. We studied the effect of arsenic in cardiovascular tissues from an arsenic exposure heart patient group in Antofagasta, Chile, against a group of non-arsenic exposure patients. Total arsenic concentrations were measured in 215 pieces of cardiovascular tissue of the arsenic exposure group, and 25 pieces of tissue of the control group. Each patient was asked to complete a questionnaire. Determination of total arsenic was done by HG-AAS, HG-AFS and ICP-MS; speciation analysis was by HPLC-ICP-MS. Auricle, saphenous veins, mammary arteries, and pooled fat samples from the arsenic exposure group gave concentrations of arsenic within the following ranges
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
