Here we evaluate the excess lifetime cancer risk (ELCR) posed by 10 PAH-contaminated soils using (i) the currently advocated, targeted chemical-specific approach that assumes dose additivity for carcinogenic PAHs and (ii) a bioassay-based approach that employs the in vitro mutagenic activity of the soil fractions to determine levels of benzo[a]pyrene equivalents and, by extension, ELCR. Mutagen...

Microfabricated devices for the electrochemical detection of single DNA base changes in cancer cell lines are highly desirable due to the inherent advantages such as portability, simplicity, and the rapid and inexpensive nature of electrochemical readout methods. Moreover, molecular sensors that use microscale-footprint working electrodes have shown high signal-to-noise ratio. Herein we report ...

A case study of the cancer risk to humans posed by persistent organic pollutants (POPs) in an industrial area of China, which has a long history of contamination from many sources, is presented. Relatively great concentrations of POPs around the chemical industrial parks have the potential to be chronically carcinogenic to local people. Sixteen individual PAHs listed for priory control by the U...

Soil samples from the three residential hubs of Chittagong city, Bangladesh were analyzed using gamma spectrometry to estimate radiation hazard due to natural radioactive sources and anthropogenic nuclide (137)Cs. The activity concentration of (226)Ra was found to be in the range 11-25 Bq.kg(-1), (232)Th in the range 38-59 Bq.kg(-1) and (40)K in the range 246-414 Bq.kg(-1). These results were u...

The functional coupling of neural circuits between the upper and lower limbs involving rhythmic movements is of interest to both motor control research and rehabilitation science. This coupling can be detected by examining the effect of remote rhythmic limb movement on the modulation of reflex amplitude in stationary limbs. The present study investigated the extent to which rhythmic leg pedalin...

BACKGROUND This study was focused on the probability of carcinogen risk of low-level ingestion and dermal exposure with polycyclic aromatic hydrocarbons (PAHs) from drinking water in Tehran, capital of Iran. METHODS Concentrations of 16 PAHs were measured in the tap, bottled and heated tap water in four different seasons. Using a questionnaire-based survey, exposure with PAHs from drinking wa...

31 The functional coupling of neural circuits between the upper and lower 32 limbs involving rhythmic movements is of interest to both motor control 33 research and rehabilitation science. This coupling can be detected by 34 examining the effect of remote rhythmic limb movement on the modulation 35 of reflex amplitude in stationary limbs. The present study investigated the 36 extent to which rh...

Radioactivity measurements for naturally occurred radionuclides of 40K, 226Ra, 228Ra were carried out in some agricultural products harvested from two oil fields within the Nigeria Delta Region of Nigeria. The values obtained were used to determine the excess lifetime cancer risk (ELCR) and the radiation health hazard indices. Results show that the mean calculated ELCR values obtained from vege...

Polycyclic aromatic hydrocarbons (PAHs) are a group of toxic chemicals formed during incomplete combustion organic materials. In this study, the 16 PAHs were investigated in meat and products. Literature search was performed Scopus, PubMed Web Science databases from 2000 to 2021. Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) used. Fifteen (15) studies containing 155 ob...
