Special vulnerability of children to environmental exposures

Sly, J. Leith / Carpenter, David O.

The environment in which fetal and childhood development occurs is very important. Unfortunately, poverty is a major risk factor for both exposures and childhood and later-life disease resulting from exposures to both environmental chemicals and infectious agents.

Improving access to adequate water and basic sanitation services in Indonesia

Haryanto, Budi / Sutomo, Sumengen

The development of water and basic sanitation services in Indonesia does not indicate any significant progress in the last two decades. The prevalence of water-borne diseases tends to increase yearly, which poses a risk for a population of over a million people. Therefore, it is not realistic to achieve the Millennium Development Goals target by 2015. Redefining approaches like providing integrated programs and action in water and sanitation services must be a priority to protect human health in Indonesia.

A framework for assessing and predicting the environmental health impact of infectious diseases: a case study of leptospirosis

Lau, Colleen / Jagals, Paul

The application of an integrated environmental health impact assessment (IEHIA) methodology to assess the health impact of an infectious disease was shown to enhance the ability to quantify associations between a disease agent and its health impact by taking into account the environmental drivers of transmission, human behaviour, socioeconomic factors, and the multiple pathways through which exposure and infection could occur.

Nanoparticles in the environment: stability and toxicity

Kim, Hyun-A / Choi, Yoo Jin / Kim, Kyoung-Woong / Lee, Byung-Tae / Ranville, James F.

This review presents a brief overview of the fate, behavior, and ecotoxicity of nanoparticles (NPs) in the environment. The fate and transport of NPs, which can be affected by various environmental conditions like light, pH, ionic strength, and type and concentration of cations, are important for the examination of the life cycle of NPs.

Nature’s cure for cleanup of contaminated environment – a review of bioremediation strategies

Prasad, Majeti Narasimha Vara / Prasad, Rajendra

Bioremediation technologies resting upon the vast potential of biodiversity for the monitoring and abatement of environmental pollution have been briefly reviewed.

Arsenic and human health: epidemiologic progress and public health implications

Argos, Maria / Ahsan, Habibul / Graziano, Joseph H.

Herein, we emphasize the role of recent genetic and molecular epidemiologic investigations of arsenic toxicity. Additionally, we discuss considerations for the public health impacts of arsenic exposure through drinking water with respect to primary and secondary prevention efforts.

Direct potable reuse of reclaimed wastewater: it is time for a rational discussion

Arnold, Robert G. / Sáez, Avelino E. / Snyder, Shane / Maeng, Sung Kyu / Lee, Changha / Woods, Gwendolyn J. / Li, Xiangdong / Choi, Heechul

Engineered solutions to relieve water stress are frequently based on the use of water of impaired initial quality. Chief among these impaired waters is reclaimed wastewater. For the most part, however, the breadth of both acceptable uses and use-dependent degree of treatment for reclaimed wastewater remain to be established.

Persistent toxic substances: sources, fates and effects

Wong, Ming H. / Armour, Margaret-Ann / Naidu, Ravi / Man, Ming

This article is an attempt to review the current status of Persistently Toxic Substances (PTS) in our environment, citing case studies in China and North America, and whether our existing drinking water treatment and wastewater treatment processes are adequate in removing them from water. Some management issues of these emerging chemicals of concern are also discussed.

  • Total arsenic concentrations in Chinese children’s urine by different geographic locations, ages, and genders 2017-04-26

    Abstract

    Little is known about the variation of Chinese children’s exposure to arsenic by geography, age, gender, and other potential factors. The main objective of this study was to investigate the total arsenic concentration in Chinese children’s urine by geographic locations, ages, and genders. In total, 259 24-h urine samples were collected from 210 2- to 12-year-old children in China and analyzed for total arsenic and creatinine concentrations. The results showed that the upper limit (upper limit of the 90% confidence interval for the 97.5 fractile) was 27.51 µg/L or 55.88 µg/g creatinine for Chinese children. The total urinary arsenic levels were significantly different for children in Guangdong, Hubei, and Gansu provinces (P < 0.05), where the upper limits were 24.29, 58.70, and 44.29 µg/g creatinine, respectively. In addition, the total urinary arsenic levels were higher for 2- to 7-year-old children than for 7- to 12-year-old children (P < 0.05; the upper limits were 59.06 and 44.29 µg/g creatinine, respectively) and higher for rural children than for urban children (P < 0.05; the upper limits were 59.06 and 50.44 µg/g creatinine, respectively). The total urinary arsenic levels for boys were not significantly different from those for girls (P > 0.05), although the level for boys (the upper limit was 59.30 µg/g) was slightly higher than that for girls (the upper limit was 58.64 µg/g creatinine). Because the total urinary arsenic concentrations are significantly different for general populations of children in different locations and age groups, the reference level of total urinary arsenic might be dependent on the geographic site and the child’s age.

  • Distribution, seasonal variation and inhalation risks of polychlorinated dibenzo- p -dioxins and dibenzofurans, polychlorinated biphenyls and polybrominated diphenyl ethers in the atmosphere of Beijing, China 2017-04-26

    Abstract

    Spatial distribution, seasonal variation and potential inhalation risks of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) were investigated in the atmosphere of Beijing, using passive air samplers equipped with polyurethane foam disks. Concentrations of ΣPCDD/Fs, ΣPCBs and ΣPBDEs ranged from 8.4 to 179 fg WHO2005-TEQ/m3, 38.6–139 and 1.5–176 pg/m3, respectively. PCDFs showed higher air concentrations than those of PCDDs, indicating the influence of industrial activities and other combustion processes. The non-Aroclor congener, PCB-11, was detected in air (12.3–99.4 pg/m3) and dominated the PCB congener profiles (61.7–71.5% to ∑PCBs). The congener patterns of PBDEs showed signatures from both penta-BDE and octa-BDE products. Levels of PCDD/Fs, PCBs and PBDEs at the industrial and residential sites were higher than those at rural site, indicating human activities in urban area as potential sources. Higher air concentrations of PCDD/Fs, PCBs and PBDEs were observed in summer, which could be associated with atmospheric deposition process, re-volatilization from soil surface and volatilization from use of technical products, respectively. Results of inhalation exposure and cancer risk showed that atmospheric PCDD/Fs, dioxin-like PCBs and PBDEs did not cause high risks to the local residents of Beijing. This study provides further aid in evaluating emission sources, influencing factors and potential inhalation risks of the persistent organic pollutants to human health in mega-cities of China.

  • Remediation of soils contaminated with heavy metals with an emphasis on immobilization technology 2017-04-26

    Abstract

    The major frequent contaminants in soil are heavy metals which may be responsible for detrimental health effects. The remediation of heavy metals in contaminated soils is considered as one of the most complicated tasks. Among different technologies, in situ immobilization of metals has received a great deal of attention and turned out to be a promising solution for soil remediation. In this review, remediation methods for removal of heavy metals in soil are explored with an emphasis on the in situ immobilization technique of metal(loid)s. Besides, the immobilization technique in contaminated soils is evaluated through the manipulation of the bioavailability of heavy metals using a range of soil amendment conditions. This technique is expected to efficiently alleviate the risk of groundwater contamination, plant uptake, and exposure to other living organisms. The efficacy of several amendments (e.g., red mud, biochar, phosphate rock) has been examined to emphasize the need for the simultaneous measurement of leaching and the phytoavailability of heavy metals. In addition, some amendments that are used in this technique are inexpensive and readily available in large quantities because they have been derived from bio-products or industrial by-products (e.g., biochar, red mud, and steel slag). Among different amendments, iron-rich compounds and biochars show high efficiency to remediate multi-metal contaminated soils. Thereupon, immobilization technique can be considered a preferable option as it is inexpensive and easily applicable to large quantities of contaminants derived from various sources.
