Is prenatal arsenic exposure associated with salivary cortisol in infants in Arica, Chile? An exploratory cohort study

open access: yesAnnals of Agricultural and Environmental Medicine, 2019
Introduction In animal models, gestational exposure to inorganic arsenic has been associated with higher corticosterone concentration and consequent impairment of stress control in offspring.

Littoral sediment arsenic concentrations predict arsenic trophic transfer and human health risk in contaminated lakes.

open access: yesPLoS ONE, 2023
Lake sediments store metal contaminants from historic pesticide and herbicide use and mining operations. Historical regional smelter operations in the Puget Sound lowlands have resulted in arsenic concentrations exceeding 200 μg As g-1 in urban lake ...

Mortality in young adults following in utero and childhood exposure to arsenic in drinking water. [PDF]

open access: yes, 2012
BackgroundBeginning in 1958, the city of Antofagasta in northern Chile was exposed to high arsenic concentrations (870 µg/L) when it switched water sources. The exposure abruptly stopped in 1970 when an arsenic-removal plant commenced operations.

Acute toxicity of arsenic and oxidative stress responses in the embryonic development of the common South American toad Rhinella arenarum [PDF]

open access: yes, 2015
Arsenic (As), a natural element of ecological relevance, is found in natural water sources throughout Argentina in concentrations between 0.01mg/L and 15mg/L. The autochthonous toad Rhinella arenarum was selected to study the acute toxicity of As and the

Arsenic Exposure During Pregnancy and Childhood: Factors Explaining Changes over a Decade

open access: yesToxics
Arsenic chronic exposure, particularly in its inorganic form, represents a significant public health concern. This study was conducted in Arica, the northernmost city in the country, whose inhabitants have been exposed to inorganic arsenic both naturally

Effect of arsenic-phosphorus interaction on arsenic-induced oxidative stress in chickpea plants [PDF]

open access: yes, 2009
Arsenic-induced oxidative stress in chickpea was investigated under glasshouse conditions in response to application of arsenic and phosphorus. Three levels of arsenic (0, 30 and 60 mg kg−1) and four levels of P (50, 100, 200, and 400 mg kg−1) were ...

Influence of EDTA and chemical species on arsenic accumulation in Spirodela polyrhiza L. (duckweed) [PDF]

open access: yes, 2008
The influence of ethylenediaminetetraacetic acid (EDTA) and chemical species on arsenic accumulation in aquatic floating macrophyte Spirodela polyrhiza L. (duckweed) was investigated. The uptake of inorganic arsenic species (arsenate; As(V) and arsenite;

Paving the Way to Elucidate Hg's Role in Tumorigenesis

open access: yesAdvanced Science, EarlyView.
Tumorigenesis can result from diverse environmental carcinogens. Among them, mercury—a lifelong bioaccumulative Group 2B carcinogen—has tumorigenic potential that remains poorly understood due to confounding co‐exposures and limited organ‐specific data.
