malondialdehyde (mda) is widely used as a biomarker for assessing oxidative stress in biomedical fields. lipid peroxidation is a chain phenomenon resulting in the formation of various active compounds that result in cellular damage. biomonitoring of mda has been used in both in-vivo and in-vitro studies as a key biomarker for various disease patterns including hypertension, diabetes, atheroscle...
Evaluation of a larger number of chemicals in commerce from the perspective of potential human health risk has become a focus of attention in North America and Europe. Screening-level chemical risk assessment evaluations consider both exposure and hazard. Exposures are increasingly being evaluated through biomonitoring studies in humans. Interpreting human biomonitoring results requires compari...
This study is an attempt to evaluate the biomonitoring capabilities of rock oyster, Saccostrea cucullata, for mercury (Hg) pollution. The oyster and sediment samples were collected from 10 rocky habitats of Qeshm and Hormoz Islands in the Persian Gulf. The concentration of mercury in the shell and soft tissues of the oysters and sediments were analyzed using an advanced mercury analyzer. Biot...
The concept of surrogates in biodiversity assessments has been widely accepted the recent years. Surrogates are taxonomic groups that indicate overall at a particular site. Zooplankton is an important component aquatic ecosystem, playing major role energy transfer between phytoplankton or producers and consumers higher trophic levels. In this study zooplanktons were considered as for biomonitor...
BACKGROUND Bisphenol A (BPA) is one of the highest-volume chemicals produced worldwide, and human exposure to BPA is thought to be ubiquitous. Thus, there are concerns that the amount of BPA to which humans are exposed may cause adverse health effects. Importantly, results from a large number of biomonitoring studies are at odds with the results from two toxicokinetic studies. OBJECTIVE We ex...
The conflicting needs of water managers (i.e., quick relevant operational responses) and ecologists (i.e., time consuming in-depth research) have been noted in freshwater biomonitoring and exist even today. To contribute to solving this dilemma, we are proposing a novel biomonitoring approach, which among many others, could be successfully used in this field and further developed in the future....
background: marine pollution is a global environmental problem that its monitoring by ideal biomonitors is of great importance. marine organisms, especially mussels, have the ability to accumulate metals from the environment they can be considered as a biomonitoring agent. methods: in this study, concentrations of heavy metals were measured in saccostrea cucullata collected from seven sites on ...
Using modern analytical technology, it is now possible to measure almost any chemical present in our bodies. The future role of classical exposure assessment will perhaps be marginalized because biomonitoring programs can directly measure the concentration of chemicals that are present in biologic matrices. Although the concentration of chemicals in the environment will continue to be measured ...
Introduction Environmental health researchers and government scientists in the United States typically encounter a paucity of information on both toxicity and exposure for most chemicals in commerce (Judson et al. 2009; Egeghy et al. 2012; Neltner et al. 2013; Silbergeld et al. 2015). Even if data are available, federal and state agencies have limited capacity for assessing health risks (GAO 20...
Advances in both sensitivity and specificity of analytical chemistry have made it possible to quantify substances in human biological specimens, such as blood, urine, and breast milk, in specimen volumes that are practical for collection from individuals. Research laboratories led by the Centers for Disease Control and Prevention (CDC) in its series National Report on Human Exposure to Environm...
