Health issues ingestion

In occupational exposures, for example, the manufacture of explosives, the main health issue has been the occurrence of skin disease. Systemic poisoning is rare. Picric acid is irritating to eyes and skin. Dermal exposure may cause local or generalized allergic reactions. It causes yellow staining of skin. Absorption into the skin or ingestion may cause nausea,... [Pg.2023]

It is no wonder that bracken fern has attracted the attention of scores of research groups from an array of disciplines over the past one hundred years since it was discovered that cattle was harmed by its ingestion [34,35], Considerable efforts and resources have been invested in trying to explore and understand the intimate way of action of its many bioactive components [36-42], Several reviews have appeared over the years on various aspects of bracken toxicity [27,28,36,43-50], Interest around this plant has been spurred by recent discoveries relating bracken invasion with certain human health issues to be discussed here. The present chapter also covers the most relevant and recent aspects of the chemistry and mode of action of those bracken compounds that constitute the most biologically active fraction. [Pg.688]

Given its widespread use, sodium chloride is obviously safe for consumption by most humans under normal conditions. As with any chemical compound, consumption of a large excess of sodium chloride can be harmful. The one health issue of greatest concern has to do with high blood pressure. Scientists have learned that the ingestion of large amounts of sodium can contribute to hypertension (high blood pressure), which in turn is associated with increased risk for heart attacks and stroke. [Pg.738]

Incidental soil ingestion by children is an important pathway in assessing public health risks associated with exposure to arsenic-contaminated soils. Incidental ingestion of soil represents the principal direct pathway for exposure to nondietary sources of As in contaminated areas. The importance of soil ingestion by children as a health issue has been reported by numerous researchers and fully illustrates the importance of this pathway in terms of subsequent chemical exposure (4-8). [Pg.118]

Resuspended lead-containing dusts are not inconsequential for public health. One health issue with reentrained dust lead is that of exposure risks to adults by inhalation of particles or risks to young children from both inhalation and ingestion of resuspended and redeposited dust lead. Cowherd et al. (1985) calculated respirable (PMio) levels of resuspended dust lead through the equation below ... [Pg.96]

No animal or human data were available for inhalation exposure. There are no data regarding effects in humans after oral exposure. Information is available in animals regarding health effects following acute, intermediate, and chronic oral ingestion of diisopropyl methylphosphonate. The animal data obtained after oral exposure indicate that diisopropyl methylphosphonate is moderately toxic after acute bolus exposure but has a lower order of toxicity after intermediate and chronic exposures in food. No data were found on the toxicity of diisopropyl methylphosphonate after exposure in drinking water. Further, diisopropyl methylphosphonate is rapidly metabolized and excreted and does not accumulate. It does not appear to have reproductive or developmental effects. At the doses tested, it does not appear to be an acetylcholinesterase inhibitor, although this issue has not been resolved yet. Limited data are available for dermal exposure in humans and animals. Diisopropyl methylphosphonate does not appear to be a... [Pg.79]

Even though they are found in concentrations well below the therapeutical level, a number of issues suggest the need for more knowledge of the potential health effects of highly diluted pharmaceuticals, ingested over the whole life span, for non-target organisms, as well as for human health. [Pg.229]
