Maximum exposure levels for xylene, formaldehyde and acetaldehyde in cars.

2004

Although millions of individuals are exposed to emissions from articles inside cars, relatively little has been published about possible adverse health effects and about exposure levels that can be considered safe or "acceptable". Xylene, formaldehyde and acetaldehyde represent typical examples of relevant volatile organic substances (VOC) released from articles inside cars. Recently, a concept for derivation of maximum exposure levels for volatile organic substances in cars has been published. In the present study we applied this concept to derive maximum exposure levels for xylene, formaldehyde and acetaldehyde and compared the resulting concentrations to exposure levels usually found ins…

Addressing Exposome: An Innovative Approach to Environmental Determinants in Pediatric Respiratory Health

2022

Developmental age is particularly vulnerable to impacts of environmental exposures. Until recent years, the field of environment and child health has predominantly relied on the study of single exposure–health effect relationships. The exposome is an emerging concept in epidemiology, encompassing the totality of the exposures experienced by an individual throughout life and their changes over time. This innovative approach provides a risk profile instead of individual predictors. Exposome research may contribute to better understand the complex relationships between environmental exposures and childhood respiratory health, in order to implement prevention strategies and mitigate adverse hea…

SULT1A1 gene deletion in BRCA2-associated male breast cancer: a link between genes and environmental exposures?

2013

SULT1A1, a member of sulfotransferase superfamily, is a drug and hormone metabolizing enzyme involved in the metabolism of a variety of potential mammary carcinogens of endogenous and exogenous origin. Interestingly, the metabolic activity of SULT1A1 can be affected by varia- tions in gene copy number. Male Breast Cancer (MBC) is a rare disease and less investigated disease compared to female BC (FBC). As in FBC, the concurrent effects of genetic risk factors, particularly BRCA2 mutations, increased exposure to estrogens and environmental carcinogens play a relevant role in MBC. By quantitative real-time PCR with TaqMan probes, we investigated the presence of SULT1A1 gene copy number variat…

Environment and Endometriosis: A toxic relationship

2015

Endometriosis is a common, be- nign, estrogen-dependent gynecological dis- ease that represents one of the main causes of hospitalization in industrialized countries. It is well established that a large amount of natural and man-made chemicals are present in the en- vironment and both humans and animals are exposed to them. Dioxin and dioxin-like com- pounds have long biological half-life, can accu- mulate within the organism and could negative- ly affect several physiological processes. The purpose of this review is to provide an overview of the possible relationship between these chemicals and the pathogenesis of en- dometriosis.

BACKGROUND: While noise annoyance has become recognized as an important environmental stressor, its association to mental health has hardly been studied. We therefore determined the association of noise annoyance to anxiety and depression and explored the contribution of diverse environmental sources to overall noise annoyance. PATIENTS AND METHODS: We investigated cross-sectional data of n = 15.010 participants of the Gutenberg Health Study (GHS), a population-based, prospective, single-center cohort study in Mid-Germany (age 35 to 74 years). Noise annoyance was assessed separately for road traffic, aircraft, railways, industrial, neighborhood indoor and outdoor noise ("during the day"; "i…

Multiple pregnancies and environmental exposure: An impact of air pollution on fetal growth?

2018

Introduction Multiple pregnancies display all the complications of singletons, but in highest frequencies, especially for fetal growth abnormalities. In singletons, air pollution seems to be negatively associated with fetal growth. A similar relationship in multiple pregnancies can be expected. However, multiple pregnancies are systematically excluded from the studies of the impact of air pollution on pregnancy outcomes. This study aims to analyze in a population of multiple pregnancies the relationship between fetal growth restriction (FGR), small for gestational age (SGA) and environmental chronic exposure to air pollution in moderately polluted cities. Methods All the multiple pregnancie…

Analysis of seroprevalence against [i]Coxiella burnetii[/i] in a sample of farm workers in Western Sicily

2015

[b]Introduction and objective. [/b]Little is known about the development of chronic Q fever caused by [i]Coxiella burnetii [/i]in occupational risk groups and in the general population in Italy, as well as in many countries in the world. The aim of this study was to highlight the presence of the infection in a sample of workers operating outdoors (but not directly in contact with animals), in three provinces of western Sicily, in order to detect the human seroprevalence and compare the obtained data with those found in animals raised in the same territory. [b]Materials and methods.[/b] The study included 126 generic seasonal agricultural workers (labourers), 84 male and 42 female; none of w…

Hazardous air pollutants and primary liver cancer in Texas.

2016

The incidence of hepatocellular carcinoma (HCC), the most common primary liver cancer, is increasing in the US and tripled during the past two decades. The reasons for such phenomenon remain poorly understood. Texas is among continental states with the highest incidence of liver cancer with an annual increment of 5.7%. Established risk factors for HCC include Hepatitis B and C (HBV, HCV) viral infection, alcohol, tobacco and suspected risk factors include obesity and diabetes. While distribution of these risk factors in the state of Texas is similar to the national data and homogeneous, the incidence of HCC in this state is exceptionally higher than the national average and appears to be di…

No influence of magnetic fields on cell cycle progression using conditions relevant for patients during MRI.

2003

The purpose of this study was to examine whether exposure to magnetic fields (MFs) relevant for magnetic resonance imaging (MRI) in clinical routine influences cell cycle progression in two tumor cell lines in vitro. HL60 and EA2 cells were exposed to four types of MFs: (i) static MF of 1.5 and 7.05 T, (ii) extremely low frequency magnetic gradient fields (ELFMGFs) with ± 10 mT/m and 100 Hz, as well as ± 100 mT/m and 100 Hz, (iii) pulsed high frequency MF in the radiofrequency (RF) range (63.6 MHz, 5.8 μT), and (iv) a combination of (i–iii). Exposure periods ranged from 1 to 24 h. Cell cycle distribution (G0/G1, S, and G2/M phases) was analyzed by flow cytometry. Cell cycle analysis did not…
