AI Article Synopsis
- Arsenic, cadmium, and mercury are toxic elements that can lead to various illnesses, including hypertension.
- The review outlines several proposed mechanisms linking exposure to these metals and hypertension, such as oxidative stress, impaired nitric oxide signaling, and renal damage.
- It emphasizes the need for further epidemiological studies to explore how factors like age, gender, and lifestyle affect the relationship between metal exposure and hypertension.
Article Abstract
Arsenic (As), cadmium (Cd), and mercury (Hg) are toxic elements widely distributed in the environment. Exposure to these elements was attributed to produce several acute and chronic illnesses including hypertension. The aim of this review is to provide a summary of the most frequently proposed mechanisms underlying hypertension associated with As, Cd, and Hg exposure including: oxidative stress, impaired nitric oxide (NO) signaling, modified vascular response to neurotransmitters and disturbed vascular muscle Ca signaling, renal damage, and interference with the renin-angiotensin system. Due to the complexity of the vascular system, a combination rather than a singular mechanism needs to be considered. In addition, epidemiological findings showing the relationship between various biomarkers of metal exposure and hypertension are described. Given the complex etiology of hypertension, further epidemiological studies evaluating the roles of confounding factors such as age, gender, and life style are still necessary.

Salt use patterns and heavy metal urinary excretion.

Background: Salt usage patterns have been associated with a risk of multiple diseases; however, their relationship with heavy metal exposure has not been extensively studied.
Methods: This study analyzed survey data from 11,574 NHANES participants. Weighted linear regression models were used to examine the relationship between the type of salt used by participants, the frequency of adding salt at the table, and the frequency of adding regular or seasoned salt to cooking or food preparation, and urinary concentrations of 10 heavy metals.

Heavy metals like lead, mercury, cadmium, and arsenic are environmental pollutants that accumulate in ecosystems and pose significant health risks to humans and wildlife, primarily through food chain contamination where plants absorb heavy metals, affecting their growth and threatening consumer health. Cognitive and cardiovascular functions are particularly affected by exposure to heavy metals even at low concentrations through the induction of oxidative stress. Various analytical techniques are used in measuring heavy metals in different environmental and biological samples.

Background: Preterm birth (PTB) is a common pregnancy complication associated with significant neonatal morbidity. Prenatal exposure to environmental chemicals, including toxic and/or essential metal(loid)s, may contribute to PTB risk.
Objective: We aimed to summarize the epidemiologic evidence of the associations among levels of arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), manganese (Mn), lead (Pb), and zinc (Zn) assessed during the prenatal period and PTB or gestational age at delivery; to assess the quality of the literature and strength of evidence for an effect for each metal; and to provide recommendations for future research.
Soil toxicity, biochemical and histopathological alterations of the cattle egret (Bubulcus ibis) liver at Sharkia province, Egypt, under soil pollution.

The residual concentration of pesticides and heavy metals (arsenic, mercury, selenium, lead, cadmium, and aluminum) was measured in the soil and the cattle egret (Bubulcus ibis) liver from two localities at Sharkia Governorate, Egypt. The pesticide residues have taken the following pattern: chlorpyrifos > metalaxyl > piperonyl butoxide > thiophanate-methyl, in the soil. The residual concentration of pesticides was greater in the soil at Kafr El-Ashraf village (agricultural site) than at El-Qanayat city (garbage site) during the summer season of 2021 compared with the winter season of 2022.

Urban rivers are one of the main water sources for local residents. However, the rapid industrialization and urbanization caused serious heavy metals pollution in urban rivers, which posed harmful impact on human health and ecosystem. In this study, 134 sediment samples were collected from urban rivers in a typical Economic and Technological Development Zone (ETDZ) to evaluate the contamination status, ecological risk, biotoxicity, and potential source of 8 heavy metals including arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), plumbum (Pb), and zinc (Zn).
