Short-chain halogenated aliphatics, such as chlorinated ethenes, constitute a large group of priority pollutants. This paper gives an overview on the chemical and physical properties of chlorinated aliphatics that are critical in determining their toxicological characteristics and recalcitrance to biodegradation. The toxic effects and principle metabolic pathways of halogenated ethenes in mamma...

The unambiguous identification and quantification of hazardous materials is of increasing importance in many sectors such as waste disposal, pharmaceutical manufacturing, and environmental protection. One particular problem in waste disposal and chemical manufacturing is the identification of solvents into chlorinated or non-chlorinated. In this work we have used Raman spectroscopy as the basis...

Semi volatile organochemicals such as chlorinated organophosphorus and organotin compounds are detected in many indoor materials and residential house dust samples. Chlorinated phosphorus based flame retardants are found in 90 % of over 1,500 house dust samples ranging from 0.1 to 1,300 mg/kg. The results of material samples show that many polyurethane soft foams, sealants, and finishes contain...

A total of 144 Kg of strawberry and 38 soil samples, representing two types of farming production e.g. conventional (C), organic (O), was collected from (Bilbeis and AL-Salhia, New AL-Sharqiya governorate) Egypt. Pesticides residues were determined by gas chromatography with mass selective detector (GC-MSD). This method used to determine 86 pesticide residues with a broad range of physico-chemi...

BACKGROUND Polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) are neurodevelopmental toxicants, but few studies have examined associations with autism spectrum disorder (ASD). OBJECTIVES We aimed to determine whether prenatal exposure to PCBs and OCPs influences offspring risk of ASD and intellectual disability without autism (ID). METHODS We conducted a population-based ...

Concentrations of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), polychlorinated biphenyls (PCBs), and organochlorine pesticides were measured in the serum of a sample of the New Zealand population aged 15 years and older. This was the first study to obtain representative measures of PCDDs, PCDFs and PCBs in the adult population of an entire country. Serum sam...

The Australian sheep blowfly (Lucilia cuprina) and the sheep body louse (Bovicola ovis) have both demonstrated their propensity to develop resistance to insecticides used for their control. Most populations of L. cuprina contain individuals resistant to organochlorines and organophosphates. Some are also resistant to benzoylphenyl ureas. Many populations of B. ovis are resistant to pyrethroid i...
