“…Because people spend more time in their homes than in other indoor areas, 49 the impact of radon on the human body was assessed according to residence time and occupation. For many studies, in order to estimate the annual indoor exposure time, an indoor occupancy factor (0.8) was applied over 8760 h. 35,39,42 In this study, we conducted a survey and analysed residential time in houses according to the job and residential housing type. The assessment was based on measurement results of indoor radon concentration and surveys of the time spent in homes conducted with 620 residents from 17 administrative districts.…”

“…The methods used to assess the effective dose and excess cancer risk were from previous studies. [34][35][36][37][38][39] The effective dose and the excess risk of lung cancer were derived from survey results and annual radon concentration measurements. Effective dose was calculated using criteria described in the UNSCEAR report.…”

More than 50% of the worldwide effective radiation dose from natural sources is known to be due to 222 Rn. Indoor radon levels were measured in homes with long-term exposure and in relation to time spent for residents. Measurements were conducted after categorizing homes by type, and the results (mean AE S.D) showed that detached houses, apartments and multifamily houses had radon concentrations of 97 AE 110, 51 AE 24 and 59 AE 34 Bq/m 3 , respectively. Surveys were conducted with 620 people to analyse resident awareness of radon levels and time that residents spend in homes. Using these results, the annual effective dose and risk level were computed. The survey showed that residents of Korean homes had little awareness regarding the source of radon, exposure routes and contamination levels. The excess risk of lung cancer after exposure for 70 years was determined to be 0.55/100 people, which jumped to 2.7/100 people for residents in detached houses in highly exposed areas. Compared to the effects of radon exposure in workplaces and schools, the health risks from radon in Korean homes are especially high. Therefore, the management policies for susceptible groups are important.

“…However, mercury is a dangerous heavy metal because of its toxicity and bio-accumulation in many species. This has triggered the search for less-toxic alternatives [5][6][7]. Nowadays, carbon is one of the most advantageous materials for low-cost and flexible-design electrodes.…”

Paper-Based Working Electrodes Coated with Mercury or Bismuth Films for Heavy Metals Determination

Paper-based carbon working electrodes were modified with mercury or bismuth films for the determination of trace metals in aqueous solutions. Both modification procedures were optimized in terms of selectivity and sensitivity for the determination of different heavy metals, aiming their simultaneous determination. Cd (II), Pb (II) and In (III) could be quantified with both films. However, Cu (II) could not be determined with bismuth films. The modification with mercury films led to the most sensitive method, with linear ranges between 0.1 and 10 µg/mL and limits of detection of 0.4, 0.1, 0.04 and 0.2 µg/mL for Cd (II), Pb (II), In (III) and Cu (II), respectively. Nevertheless, the bismuth film was a more sustainable alternative to mercury. Tap-water samples were analyzed for the determination of metals by standard addition methodology with good accuracy, by using a low-cost and easily disposable paper-based electrochemical platform. This system demonstrated its usefulness for monitoring heavy metals in water.

A sensor for Hg (II) determination in water was developed by using paper working electrodes modified with nanomaterials. The cellulose matrix was modified with hybrids of carbon nanofibers (CNFs) or reduced graphene oxide (rGO) and gold nanoparticles (AuNPs), in order to increase the selectivity and sensitivity. The AuNPs helped the electrodeposition of Hg (II) at more positive potentials, due to their affinity for mercury. The determination was possible up to 1.2 µM with no interference of other heavy metals such as Cd (II), Pb (II), Cu (II) and Zn (II). The CNFs/AuNPs modified paper-based electrode was the most sensitive option with a detection limit of 30 nM.River water samples were evaluated by the standard addition method.
