Acute occupational phosphine intoxications in the maritime shipping sector: Belgian and French reported cases.

BACKGROUND: During ship transport of organic cargo e.g. soybeans in bulk or textiles in containers, there is a risk of pests damaging the cargo during transport as well as of unwanted global spread of organisms. Consequently, fumigation of the shipped goods is recommended. While aiming to protect the cargo from being damaged by pests during the transport time, fumigation constitutes a risk to the health of seafarers and port workers and even fatal cases are seen. Phosphine gas is increasingly applied for fumigation. Based on former experiences this article aims to describe the risk and to prov

[Determination of eight ultraviolet absorbers in surface water and wastewater by ultra performance liquid chromatography-triple quadrupole mass spectrometry].

Ultraviolet （UV） absorbers are a group of chemicals widely used in various industrial and consumer products， such as plastics， coatings， and personal care products， to protect against UV radiation. Among them， benzotriazole derivatives （e.g. UV-326， UV-327， UV-328， UV-329， and UV-P） are the most frequently employed. Owing to their widespread use and potential persistence in the environment， these compounds have been detected in various environmental matrices， including surface water， wastewater， sediment， and biota. Certain UV stabilizers have been reported to exhibit endocrine-disrupting prop

Hand dermatitis as an unsuspected presentation of textile dye contact sensitivity.

The aim of this study was to evaluate disperse dye sensitization in patients with hand dermatitis. From January 1996 to December 2000, we identified 130 patients with hand dermatitis reacting to one of the 7 dyes included in our standard series. In 82 subjects the dermatitis was localized to the hands alone, whereas 48 patients had lesions both on the hands and on other skin sites. Disperse Blue dyes, and Disperse Orange 3 were the most common sensitizers. Among the 13 subjects allergic to disperse dyes alone, we found 3 cases of occupational allergic contact dermatitis, 1 child with atopic de

Quantitative relationships of exposure to chrysotile asbestos and mesothelioma mortality.

BACKGROUND: While asbestos has long been known to cause mesothelioma, quantitative exposure-response data on the relation of mesothelioma risk and exposure to chrysotile asbestos are sparse. METHODS: Quantitative relationships of mortality from mesothelioma and pleural cancer were investigated in an established cohort of 5397 asbestos textile manufacturing workers in North Carolina, USA. Eligible workers were those employed between 1950 and 1973 with mortality follow-up through 2003. Individual exposure to chrysotile fibres was estimated on the basis of 3420 air samples covering the entire st

Carbon disulfide encephalopathy: cerebral microangiopathy.

To understand cerebral blood circulation after long-term exposure to carbon disulfide (CS2), four patients with encephalopathy and polyneuropathy, who had worked in a viscose rayon plant, were studied. Clinical and laboratory examinations, including brain magnetic resonance images (MRI), computed tomography (CT), CT perfusion, and CT angiography, were carried out. Brain CT and MRI disclosed mild cortical atrophy in all four patients, and multiple lesions in the subcortical white matter, and basal ganglia in three patients. Brain CT angiography and perfusion revealed a statistically significant

Microwave catalytic treatment using magnetically separable CoFe2O4 spinel catalyst for high-rate degradation of malachite green dye.

The release of toxic chemical dyes from the industrial effluent poses huge challenges for the environmental engineers to treat it. Azo dyes encompass the huge part of textile discharges which are difficult to degrade due to their complex chemical aromatic structures and due to the presence of strong bonds (-N=N-). Thus, the removal of a carcinogenic azo dye (i.e., malachite green (MG)), via microwave (MW) - assisted technology in the presence of spinel cobalt ferrite (CoFe2O4) catalyst was investigated. The synthesized CoFe2O4 nanoparticles were characterized via XRD, FTIR, TGA, VSM, and SEM-E

Bladder cancer: a retrospective audit at a single radiation oncology unit of an academic hospital in Johannesburg, South Africa.

BACKGROUND: Bladder cancer (BCa) is one of the most common urological cancers and remains a leading cause of cancer-related mortality worldwide. Bladder cancer is associated with a range of risk factors, with smoking being one of the most significant contributors. In addition to smoking, exposure to certain chemicals, particularly aromatic amines found in industries such as dye, rubber, leather, and textiles, also increases the risk of bladder cancer. In low-and-middle countries with lower Human Development Index (HDI), data on the underlying causes, incident rate, modes of presentation, treat

Batch and column studies for the removal of basic red-46 dye and textile by using magnesium oxide (MgO), strontium titanium trioxide (SrTiO3), cobalt- and iron-doped lanthanum chromium trioxide (Co.Fe.LaCrO3), and cadmium sulfide (CdS)-doped graphene oxide nanocomposites.

Despite efforts to reduce the risk of toxic chemicals, colors, and dyes being released into the environment from urban and industrial areas, there is still cause for concern. Colored water must be filtered and sterilized before it can be used for irrigation. The utilization of metal oxide and nanocomposite materials in wastewater treatment procedures appears to be a viable option for the future. Therefore, different compounds were doped with graphene oxide to identify the best material for dye removal by the adsorption process. According to recent studies, the ideal conditions for graphene oxi

[Obstetrical ultrasound: can the fetus hear the wave and feel the heat?].

"Fetuses can hear ultrasound and the sound is as loud as a subway train entering a station." This statement originates in a single report in a non-peer reviewed journal, despite its name 1, of a presentation at a scientific meeting by researchers who reported measuring the sound intensity in the uterus of pregnant women and being able to demonstrate the above. This was later published in a peer-review journal 2 probably not very widely read by clinicians or the general public. From time to time, the popular press or various pregnancy-related websites repeat the assertion or a worried pregnant

Trichloroethylene: An Invisible Cause of Parkinson's Disease?

The etiologies of Parkinson's disease (PD) remain unclear. Some, such as certain genetic mutations and head trauma, are widely known or easily identified. However, these causes or risk factors do not account for the majority of cases. Other, less visible factors must be at play. Among these is a widely used industrial solvent and common environmental contaminant little recognized for its likely role in PD: trichloroethylene (TCE). TCE is a simple, six-atom molecule that can decaffeinate coffee, degrease metal parts, and dry clean clothes. The colorless chemical was first linked to parkinsonism

Intracellular Pathways and Mechanisms of Colored Secondary Metabolites in Cancer Therapy.

Despite the great advancements made in cancer treatment, there are still many unsatisfied aspects, such as the wide palette of side effects and the drug resistance. There is an obvious increasing scientific attention towards nature and what it can offer the human race. Natural products can be used to treat many diseases, of which some plant products are currently used to treat cancer. Plants produce secondary metabolites for their signaling mechanisms and natural defense. A variety of plant-derived products have shown promising anticancer properties in vitro and in vivo. Rather than recreating
