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.

  • Chemical characterization and health risk assessment of soil and airborne particulates metals and metalloids in populated semiarid region, Agra, India 2016-04-13


    Rapid industrialization and urbanization have contaminated air and soil by heavy metals and metalloids from biogenic, geogenic and anthropogenic sources in many areas of the world, either directly or indirectly. A case study was conducted in three different microenvironments, i.e., residential sites, official sites and official sites; for each sites, we choose two different locations to examine the elemental concentration in fine particulate matter and soil and health risk assessment. The concentration values of heavy metals and metalloid in the air and soil in the Agra region were measured using inductively coupled plasma-atomic emission spectrophotometry. The exposure factor and health risk assessment for carcinogenic and non-carcinogenic effects due to heavy metals and metalloid contaminants have been calculated for both children and adults by following the methodology prescribed by USEPA. For the elements As, Cr, Cd, Ni and Pb selected for the carcinogenic health risk assessment, the calculated results lie above the threshold ranges. We observed the lifetime exposure to heavy metals through mainly three pathways, ingestion, inhalation and dermal contact of soil and air from that particular area. Therefore, the overall hazard quotient (HQ) values for children are more than that of adults. The assessment of health risk signifies that there were mainly three exposure pathways for people: ingested, dermal contact and inhalation. The major exposure pathway of heavy metals to both children and adults is ingestion. The values of HQ are higher than the safe level (=1), indicating a high risk exists in present condition. Meanwhile, HQs value for children is higher than that for adults, indicating that children have higher potential health risk than adults in this region.

  • Distribution and translocation of selenium from soil to highland barley in the Tibetan Plateau Kashin-Beck disease area 2016-04-12


    Kashin–Beck disease (KBD), which is still active and severe in the Tibetan Plateau, is considered to be a kind of selenium (Se)-deficient disease. Highland barley as the most popular staple food in the Tibetan Plateau is one of the dominant Se sources for local people. To improve Se levels in crops in the Tibetan Plateau KBD area, the distribution and translocation of Se from soil to highland barley in both non-KBD and KBD endemic areas were investigated. The results showed that Se levels in highland barley were too low to meet the minimum requirements of human for daily intake of Se. The total Se concentrations of highland barley fractions in KBD areas were lower than that in non-KBD areas (grain P = 0.238; straw P = 0.087; root P = 0.008). However, no significant difference was observed in corresponding cultivated soil Se between the two areas (P = 0.993). The calculation of Se transfer factors indicated that the restricting step for Se translocation was from soil to root. Water-soluble, exchangeable and fulvic acid-bound Se fractions in the soil are key species dominating in this transfer process, according to their significant correlations with root Se. Se transfer from soil to root significantly increases as the pH value of soil increases (P = 0.007), and soil organic matter content decreases (P = 0.019). The information obtained may have considerable significance for proposing effective agricultural measures to increase grain Se in KBD endemic areas.

  • Use of Maize ( Zea mays L.) for phytomanagement of Cd-contaminated soils: a critical review 2016-04-09


    Maize (Zea mays L.) has been widely adopted for phytomanagement of cadmium (Cd)-contaminated soils due to its high biomass production and Cd accumulation capacity. This paper reviewed the toxic effects of Cd and its management by maize plants. Maize could tolerate a certain level of Cd in soil while higher Cd stress can decrease seed germination, mineral nutrition, photosynthesis and growth/yields. Toxicity response of maize to Cd varies with cultivar/varieties, growth medium and stress duration/extent. Exogenous application of organic and inorganic amendments has been used for enhancing Cd tolerance of maize. The selection of Cd-tolerant maize cultivar, crop rotation, soil type, and exogenous application of microbes is a representative agronomic practice to enhance Cd tolerance in maize. Proper selection of cultivar and agronomic practices combined with amendments might be successful for the remediation of Cd-contaminated soils with maize. However, there might be the risk of food chain contamination by maize grains obtained from the Cd-contaminated soils. Thus, maize cultivation could be an option for the management of low- and medium-grade Cd-contaminated soils if grain yield is required. On the other hand, maize can be grown on Cd-polluted soils only if biomass is required for energy production purposes. Long-term field trials are required, including risks and benefit analysis for various management strategies aiming Cd phytomanagement with maize.
