Previous studies provided a strong evidence of the association between environmental exposure to cadmium (Cd) and hypertension in the general population. However, the role of Cd in pregnancy-induced hypertension (PIH) remains unclear. A total of 5429 pregnant women was selected from a birth cohort in Wuhan, China to investigate the association between Cd exposure and risk of PIH. Among them, 199 (3.7%) women were diagnosed with PIH. The Cd concentrations in maternal urine collected at delivery were measured by inductively coupled plasma mass spectrometry...

REVIEW
Philippa Douglas, Sarah Robertson, Rebecca Gay, Anna L Hansell, Timothy W Gant
BACKGROUND: Population growth, increasing food demands, and economic efficiency have been major driving forces behind farming intensification over recent decades. However, biological emissions (bioaerosols) from intensified livestock farming may have the potential to impact human health. Bioaerosols from intensive livestock farming have been reported to cause symptoms and/or illnesses in occupational-settings and there is concern about the potential health effects on people who live near the intensive farms...

REVIEW
Josef Novotný, Jiří Hasman, Martin Lepič
BACKGROUND: Unsafe management of human faecal waste represents a major risk for public health, particularly in low- and middle-income countries. Efforts to improve sanitation conditions are considerably sensitive to contextual specifics of natural and social environments. This review operationalises, analyses, and synthesises evidence of how contextual factors and motivations affect different sanitation outcomes with a specific focus on community approaches to rural sanitation. METHODS AND FINDINGS: We operationalised contextual factors and motivations as determinants that influence sanitation conditions independently of the examined intervention...

Legionellae constitute a frequent contamination of warm water systems and can lead to serious infections. Therefore, in many countries it is mandatory to monitor warm water systems for their presence. The method of examination in Germany is regulated by guideline ISO 11731 and DIN EN ISO 11731-2, and the results are reported as concentration of Legionella spp. Only limited information is available on the presence of individual species of Legionellae in the examined systems, since most investigations and research focus solely on Legionella pneumophila as the most important human pathogen...

A human biomonitoring study was carried out measuring the levels of endocrine disruptors in 252 participants (18-76 years old) recruited between February and May 2015 from the general population of Liege Province (Belgium). In this study, we reported the recent levels of cadmium and mercury in urine, some organochlorine pesticides and polychlorinated biphenyls (PCBs) in serum, and their relations to demographic characteristics, lifestyle behaviors and dietary habits. The median urinary levels of mercury and cadmium were 0...

The Advanced Reach Tool V1.5 (ART) is a mathematical model for occupational exposures conceptually based on, but implemented differently than, the "classic" Near Field/Far Field (NF/FF) exposure model. The NF/FF model conceptualizes two distinct exposure "zones"; the near field, within approximately 1m of the breathing zone, and the far field, consisting of the rest of the room in which the exposure occurs. ART has been reported to provide "realistic and reasonable worst case" estimates of the exposure distribution...

Knowledge about the change in blood nicotine concentrations during the first five minutes (acute phase) of e-cigarette vaping is important to determine whether the used product has a dependence potential or may be an efficient nicotine replacement product. To address this issue, we monitored blood nicotine levels during the acute phase in volunteers using disposable cigalikes (CLs) and a tank model (TM) and compared them with blood nicotine levels in subjects using a tobacco cigarette (TC). In parallel, heart rate changes were continually measured and withdrawal symptoms and craving were assessed with the Questionnaire on Smoking Urges before and immediately after the vaping/smoking sessions...

7-Hydroxy-3,7-dimethyl-1-octanal, also known as 7-hydroxycitronellal (7-HC, CAS No. 107-75-5) is a synthetic fragrance widely used in cosmetic and hygiene products. Due to its large scope, 7-HC was selected for the development of a biomonitoring method suitable for the general population within the frame of the cooperation project between the German Federal Ministry for the Environment (BMUB) and the German Chemical Industry Association (VCI). In a human study with 5 healthy subjects who received single dermal and oral doses 7-HC, suitable metabolites and their urinary excretion kinetics was investigated...

General population exposure to methylmercury (MeHg), the most common organic mercury compound found in the environment, occurs primarily through the consumption of contaminated fish and shellfish. Due to limited studies and lack of consideration of effect modification by fish consumption, it remains uncertain if exposure to mercury affects semen parameters. Thus, we investigated whether hair Hg levels, a biomarker of mercury exposure, were associated with semen parameters among men attending an academic fertility center, and whether this relationship was modified by intake of fish...

BACKGROUND: Existing studies exploring the association between low birth weight (LBW) and maternal fine particulate matter (aerodynamic diameter<2.5μm, PM2.5) exposure have presented equivocal results, and one of the possible reasons for this finding might be due to relatively low maternal exposures. In addition, relatively narrow maternal exposure windows to PM2.5 have not been well established for LBW. METHODS: We employed a nested matched case-control design among 43,855 term births in a large maternity and child care hospital in Jinan, China...

Salmonella spp. is one of the most important causal agents of food-borne illness in developed countries and its presence in irrigation water poses a risk to public health. Its detection in environmental samples is not easy when culture methods are used, and molecular techniques such as PCR or ribosomal rRNA probe hybridization (Fluorescent in situ Hybridization, FISH) are outstanding alternatives. The aim of this work was to determine the environmental risk due to the presence of Salmonella spp. in wastewater by culture, PCR and FISH...

Understanding waterborne protozoan parasites (WPPs) diversity has important implications in public health. In this study, we evaluated a NGS-based method as a detection approach to identify simultaneously most important WPPs using 18S rRNA high-throughput sequencing. A set of primers to target the V4 18S rRNA region of WPPs such as Cryptosporidium spp., Giardia sp., Blastocystis sp., Entamoeba spp, Toxoplasma sp. and free-living amoebae (FLA) was designed. In order to optimize PCR conditions before sequencing, both a mock community with a defined composition of representative WPPs and a real water sample inoculated with specific WPPs DNA were prepared...

The presence of Cryptosporidium and Giardia in waste water is a main concern because water reuse for irrigation can jeopardize human health. Spanish Legislation for water reuse does not oblige to analyze the presence of both pathogens Cryptosporidium and Giardia in reused water for irrigation. Therefore, the objective of this paper is to determine the influence of wastewater treatment in the increase of the consumer safety margin in relation to the presence of Cryptosporidium and Giardia in leafy green vegetables...

Heatwaves have always occurred, but they are expected to intensify in frequency, duration and intensity due to climate change. Germany (like most European countries) experienced a distinct heatwave in 2003. Afterwards local heat health action plans (HHAP) were implemented in numerous regions (for example in Hesse). This analysis was designed to compare the heat wave of 2003 with the following ones in 2006, 2010 and 2015. We discuss whether measures from the Hessian HHAP were effective in reducing mortality and identify specific characteristics of the 2003 heatwave which did not allow direct comparison...

Prenatal exposure to polybrominated diphenyl ethers (PBDEs) have been reported to impair executive function in children, but little is known whether childhood PBDE exposures play a role. Using the Health Outcomes and Measures of the Environment (HOME) Study, a prospective birth cohort in the greater Cincinnati area, we investigated the association between repeated measures of PBDEs during childhood and executive function at 8 years in 208 children and whether effect modification by child sex was present. We used child serum collected at 1, 2, 3, 5, and 8 years to measure PBDEs...

This paper investigates the removal efficiency of organic matter, nitrogen, phosphorus, coliforms and pathogens from rural domestic wastewater in a two-stage vertical flow multi-soil-layering (MSL) system. The effects of wastewater quality, season and arid climate conditions on pollutants removal efficiency by the system were examined for one year. The experimental setup included two similar MSL systems composed of two layers: soil-mixture-layers (SML) and gravel permeable layers (PL) that are arranged in a brick like pattern...

INTRODUCTION: The use of a waterpipe to smoke tobacco has emerged as a popular trend in the United States. Waterpipe smoking establishments have had an increasing presence in the U.S., despite smoke-free air legislation. Dangers of waterpipe smoking have been documented, but less data has been gathered about the waterpipe café itself. This project sought to determine a waterpipe-specific calibration factor (CF) for measuring waterpipe aerosol, and field-test this CF by conducting surveillance on the existing waterpipe cafés of western and central New York...

This article presents empirically derived conversion rules between the environmental noise exposure metrics Leq24h, LDay, LEvening, LNight, Ldn, and Lden for the noise sources road, rail and air traffic. It caters to researchers that need to estimate the value of one (unknown) noise metric from the value of another (known) metric, e.g. in the scope of epidemiological meta-analyses or systematic reviews, when results from different studies are pooled and need to be related to one common exposure metric. Conversion terms are derived using two empirical methods a) based on analyzing the diurnal variation of traffic, and b) by analyzing differences between calculated noise exposure metrics...

BACKGROUND: The protective effects of physical activity (PA) against chronic disease can be partially ascribed to its anti-inflammatory effects. On the other hand, long-term exposure to particulate matter with an aerodynamic diameter less than 2.5μm (PM2.5) may induce systemic inflammation. OBJECTIVE: To investigate the joint effects of habitual PA and long-term exposure to PM2.5 on systemic inflammation in a large cohort of Taiwanese adults. METHODS: We studied 359,067 adult participants from a cohort consisting of Taiwanese residents who participated in a standard medical examination program from 2001 to 2014...
