Simazine

Simazine is an herbicide of the triazine class, with the molecular formula C7H12ClN. [1] Under normal conditions, Simazine is a white crystalline powder. When mixed with air, its dusts can be explosive. When heated, Simazine breaks down to give toxic fumes. It melts at 225 degrees Celsius. Simazine is not very soluble in water, […]

Chemical characteristic of PM2.5 emission and inhalational carcinogenic risk of domestic Chinese cooking

To illustrate chemical characteristic of PM2.5 emissions and assess inhalational carcinogenic risk of domestic Chinese cooking, 5 sets of duplicate cooking samples were collected, using the most used 5 types of oil. The mass abundance of 14 elements, 5 water-soluble ions, organic carbon (OC), elemental carbon (EC) and 11 polycyclic aromatic hydrocarbons (PAHs) were […]

Determinants of children’s exposure to pyrethroid insecticides in western France

Pyrethroids are insecticides frequently used in agriculture and in the home; exposure occurs through dietary and non-dietary pathways, including indoor and outdoor environmental contamination. The objective of this study was to investigate the potential determinants of pyrethroid metabolite concentrations measured in children’s urine samples and in the dust of their homes. Specifically, the authors […]

An assessment of agricultural pesticide use in Iran, 2012-2014

This is the first published assessment on agricultural pesticide use in Iran with the aim to identify pesticide products with a potential of causing acute or chronic hazard to human health. It also establishes a baseline for future comparisons and for trend assessments. The amounts of imported technical materials for formulation by local manufacturers […]

Nicotine, aerosol particles, carbonyls and volatile organic compounds in tobacco-and menthol-flavoured e-cigarettes

This study aimed to assess the content of electronic cigarette (EC) emissions for five groups of potentially toxic compounds that are known to be present in tobacco smoke: nicotine, particles, carbonyls, volatile organic compounds (VOCs), and trace elements by flavour and puffing time. The authors used ECs containing a common nicotine strength (1.8%) and […]

Airborne allergic contact dermatitis caused by isothiazolinones in water-based paints: a retrospective study of 44 cases

Airborne allergic contact dermatitis caused by paints containing isothiazolinones has been recognised as a health hazard. In the present study, the authors collected epidemiological, clinical and patch test data on airborne allergic contact dermatitis caused by isothiazolinone-containing paints in France and Belgium. A descriptive, retrospective study was initiated by the Dermatology and Allergy Group […]

n-Hexane intoxication in a Chinese medicine pharmaceutical plant: a case report

n-Hexane is a well-known neurotoxicant. Polyneuropathy due to occupational n-hexane exposure has been reported worldwide, however, this case is the first report in the Chinese herb industry. A 25-year-old Asian man experienced progressive weakness and numbness in his hands and feet after working as an operator in a Chinese medicine pharmaceutical plant for the […]

Occupation-related chromium toxicity a rare cause of renal failure and rhabdomyolysis

A 21-year-old worker in a mobile phone shop, was admitted with rhabdomyolysis, renal failure, and pulmonary oedema requiring mechanical ventilation and haemodialysis. After extensive work-up and ruling out other causes, heavy metal poisoning was considered. Investigations during the course of the hospital stay revealed chromium poisoning. With repeated haemodialysis, his parameters normalised and he […]

Visual functions of workers exposed to organic solvents in petrochemical industries

The purpose of this study was to evaluate the visual functions of workers exposed to organic solvents in petrochemical industries. Thirty workers from the petroleum refinery and 30 age-matched controls (mean age) were recruited. Visual functions and occupational exposure levels were assessed among both the groups. Visual acuity, contrast sensitivity, colour vision, and visual […]

Prevalence of and work-related risk factors for hand eczema in a Norwegian general population (The HUNT Study)

Chemical exposures at work and at home may cause hand eczema. However, this has been scarcely described for Norway. In this study, the authors investigated the prevalence of, and occupational risk factors for, hand eczema in Norway. Among 50?805 respondents (aged ?20?years) to the third Nord-Trøndelag Health Study (HUNT3), 5757 persons reported ever having […]
