Welcome to the February issue of EVISA's Speciation Newsletter !

Arsenic stands as one of the most significant health hazards globally. Naturally present within the Earth's crust, it has the capacity to combine with both inorganic and organic substances, yielding a plethora of diverse compounds. The tally of identified arsenic species across various environmental domains now exceeds 100. Notably, arsenic toxicity exhibits considerable variance among distinct species, underscoring the critical necessity to comprehend these disparities in evaluating health risks linked with arsenic exposure. While a prevailing notion holds that inorganic arsenic species pose greater toxicity compared to their organoarsenical counterparts, this assertion is subject to a multitude of factors, including metabolic conversions, thereby imbuing the subject with heightened complexity. With a brief summary on arsenic toxicity, EVISA is giving access to the literature on that topic (see the news below).

The count of arsenic species identified in our environment continues to rise annually. However, certain species exhibit limited stability, rendering them vulnerable to harsh conditions that hinder their extraction and isolation.

A team of researchers hailing from the University of Bayreuth delved into the dynamics of arsenic uptake, accumulation, and speciation within rice plants. Their findings shed light on the presence of thioarsenate species not only in the paddy soil but also their formation within the plant itself (see the news below).

EVISA is keeping you updated with what is going on in speciation analysis. In this section you will find news about the most current research results, about trends, legal issues and information from manufacturers in the field of speciation analysis.

With all the links to further information and publications the News archive is a valuable collection of "hot topics" in speciation analysis. We continuously update even former news with new links and information so that all news are actual all the time.

Toxicity of arsenic species
Arsenic, a naturally occurring metalloid, is ubiquitously present in the environment. Arsenic has been listed in the first class of human carcinogen by the International Agency for Research on Cancer (IARC) and is ranked first among toxicants posing a significant potential threat to human health based on known or suspected toxicity. As confirmed by epidemiological studies, there is a strong correlation between arsenic exposure and increased incidence of cancers, such as bladder cancer, liver cancer, lung cancer, and skin cancer. In addition, arsenic poisoning can cause a variety of types of health damage, such as immune imbalance, endocrine disruption, and damage to the reproductive system.

Thioarsenate Formation in Rice Plants: A Comprehensive Study on Arsenic Uptake, Accumulation, and Speciation
A group of researchers from the University of Bayreuth investigated the uptake, accumulation and speciation of arsenic by rice plants. Their results indicate that thioarsenate species are formed within the plant.
