Exposure longterm

Additionally, after both vapor and liquid agent exposure, there are CNS effects that vary in intensity and duration. After mild to moderate exposure to nerve agent, there may be forgetfulness, an inability to concentrate, insomnia, impaired judgment, nightmares, irritability, and depression. These effects may be present for 4 to 6 weeks. They may also occur upon recovery from acute, severe effects of exposure. Longterm and low-dose effects of the nerve agents are the topic of Chapter 1 of this text. 

Severely exposed people are not likely to survive. If people survive the initial exposure, longterm effects may include kidney damage, numbness and pain in the extremities, and...

In the future, the preventive tole of toxicology will be emphasized. It will be increasingly important to develop early indicators to monitor longterm subtle exposures that predict deleterious effects that are known to have a causal relationship with occupational exposures. In addition to collection of blood and urine samples, also collection of cells from points of... 

Fish are often the focal point of interest for methylmercury contamination, representing the main exposure pathway for humans and wildlife. Unfortunately, longterm data sets with records of both mercury deposition and fish mercury concentrations over time are limited. In Sweden, Johansson etal. (2001) estimated that... 

While the aforementioned studies have described the manifestations of i n ut.ero exposure to PCP by human and animal fetuses as well as behaviors adult monkeys who had received only PCP, the longterm consequences of prenatal abuse have not been described. Therefore, this report will elaborate upon our observations of the effects of PCP upon the growth and development of 12 neonates between 2 and 18 months of age, whom we have followed from August 1983 to March 1985.

Endpoint/Concentration/Rationale In the absence of data specifically identifying AEGL-2 endpoints, the AEGL-2 was based upon a 3-fold reduction of the AEGL-3 values for all time periods. Given the steepness of the exposure-dose curve, it is believed that a 3-fold downward adjustment would be protective against serious longterm, irreversible effects, or the inability to escape. 

Alcoholism is a chronic relapsing disorder. The risk of alcoholism depends on interactions between genetic, environmental and neurobiological factors. Historically, ethanol s actions were attributed to nonspecific disruption of the lipid bilayer of neurons. It is now recognized that ethanol has specific targets, and that effects of longterm ethanol exposure are due to neuroadaptations as well as neurotoxicity [42-45]. 

Very little is known about the short-term and longterm effects of exposure to high magnetic fields.

The key limitations of the study designs are the duration of the study and the number of subjects. Since most studies conducted are short term, the potential effect of a lifetime exposure to oats requires further investigation. Long-term compliance to a gluten-free diet is one of the major difficulties in the management of celiac disease, and the collection of longterm data related to the consumption of oats is also very challenging. 

The Environmental Protection Agency (EPA) identifies the most serious hazardous waste sites in the nation. These sites make up the National Priorities List (NPL) and are targeted for longterm federal clean-up activities. Nickel has been found in at least 709 of the 1,430 current or former NPL sites. However, the total number of NPL sites evaluated is not known. As more sites are evaluated, the number of sites at which nickel is found may increase. This is important because exposure to this substance, may harm you and because these sites may be sources of exposure. 

An exception is the ophthalmic use of PFCLs (see Table 1) like perfluorooctane (PFO) and perfluorodecalin (PFD). Since the introduction of PFCLs into VR surgery in the 80s [6-8], more than 2 million patients have been treated with PFCLs intra-operatively. In addition, animal studies with at least 3 months exposure have been published [9-11]. This experience based on the high number of well-documented patient cases and the consolidated findings on the effects of a longterm treatment opens the possibility of an exemplary discussion of opportunities and drawbacks of the use of highly fluorinated liquids.
