1. Introduction. The potentially adverse effects of pesticides exposure on the general population are a public health concern ().At low levels, human beings are exposed to a variety of pesticides via contaminated food (Mercier et al., ) and household use (Trunnelle et al., ).Nevertheless, the occupationally exposed subjects or populations living near pesticide Cited by: 6.   The novel suggestion is made that total fibre length per unit volume (m/m 3) might reflect the hazard of asbestos exposure better than fibre number concentration and be easier to assess by man or machine—by counting crossing-points between fibres Cited by:

Occupational Chemical Exposures and Psychiatric Disorders Mark L. Dembert, M.D., M.P.H. Abstract Occupational exposure to metals, solvents, or pesticides can produce disorders qfbehavior, thought, or mood which can easily be misdiagnosed as 'Junctional."Accurate diagnosis obtained. report is to review the steps used in risk assessment for developmental toxicity. Two chemicals for which airborne occupational exposure can occur, ethanol and iodine, are used to illustrate the process and furnish a basis for discussing approaches to the management of risks for developmental toxicity in occupational by: 1.

Occupational dust exposure can occur in various settings, including agriculture, forestry, and hazards include those that arise from handling grain and cotton, as well as from mining coal. Wood dust, commonly referred to as "sawdust", is another occupational dust hazard that can pose a risk to workers' health.

Without proper safety precautions, dust exposure can. In previous general population-based studies, the relative risk of respiratory symptoms attributable to occupational dust exposure was approximately to Reports of the association of occupational dust exposure with chronic cough, chronic phlegm, and persistent wheeze this study are greater in subjects with the highest exposure by: 3.

The patients studied had exposure periods ranging from a few days to 18 years. Extracts of some of these woods have produced positive wheals when skin patch tests were done. In the asthma syndrome produced by exposure to western red-cedar, plicatic-acid () has been identified as the causative agent.

The number of free lung-cells was studied in guinea-pigs after acute exposure to extracts of various cotton dusts. A good correlation was found between the increase in number of leucocytes in the airways and the number of Gram-negative bacteria in the different dusts.

In such cases, the use of default assumptions and extrapolations to fill in the data gaps is a common practice. Nanoparticle risks, however, pose a new form of risk assessment by:   Uncertainties in conventional quantitative risk assessment typically relate to values of parameters in risk models.

These two chemicals could be potential chemical markers in the evaluation of occupational exposure to teak dust in workplaces. Many studies have observed an excess risk of sino-nasal cancer, particularly adenocarcinoma, among workers exposed to wood dust, and teak dust is strongly suspected to be a cause (Acheson et al., ; Andersen et al., ; Cited by: 1.

Introduction ‘All substances are poisons—the difference is in the dose’. The above aphorism is attributed to Paracelsus. It illustrates that the potential for harm is widespread and all chemicals could be toxic but the degree of harm that a chemical can inflict on a human or any other living being depends on the dose or the degree of exposure as well as on other by: 2.

Recommendation from the Scientific Committee on Occupational Exposure Limits: Risk assessment for Wood Dust Substance Woods are customarily divided into two types: hardwood and softwood.

Softwoods are generally conifers (pine, fir, spruce, cedar, etc.) and hardwoods come from deciduous. Some workplace dusts, like asbestos and silica, have their own tighter - but still inadequate and under-enforced - exposure standards.

But most fall under what used to be called the ‘nuisance dust’ standard. The lingo has recently been tweaked, with what was a ‘nuisance’ now dubbed ‘limited toxicity, poorly soluble dust.’.

Axelstad Petersen, Division of Toxicology and Risk Assessment, National Food Institute (DTU Food), Technical University of Denmark. In his letter, Tomenson1 provides his opinion on the development and use of crop-exposure matrices (CEMs) in a pooling project within the AGRICOH consortium.2 Although overall his concerns repeat acknowledged limitations of the developed CEMs, discussed in detail in our paper, we disagree with his conclusion.

Tomenson concludes that “it is difficult to see how the Cited by: 2.Dusts and disease: Occupational and environmental exposures to selected fibrous and particulate dusts.Wood dust is created during all stages of wood processing such as sawing, routing, sanding and other operations.

Workers can also be exposed when the dust becomes airborne such as when removing dust from furniture, maintenance activities, or when cleaning equipment (e.g., emptying the bag from a dust extraction system or vacuum).
