Biomonitors

Lichens are useful indicators for monitoring air pollution (312, 361, 362, 446, 458). The literature concerning air pollution and lichens is summarized continously in the journal Lichenologist .

The following methods serve as typical examples of immunoassay-based analytical methods applied to biomonitoring, environmental, and crop tissue analyses. Each method utilized a commercially available immunoassay kit that was combined with sample extraction and cleanup steps as part of an overall residue method. These methods can serve as models for resolution of similar problems. 

In natural conditions, Ceratophyllum demersum and Potamogeton pectinatus L. have been found to be effective adsorbents of Cd(II), Cu(II), and Pb(II). The adsorption percentage of the metals onto plant surfaces followed the pattern Pb(II) > Cu(II) > Cd(II). P. pectinatus biomass adsorbed a higher content of heavy metals than C. demersum. According to the results, both species are of interest in the phytoremediation and biomonitoring studies of polluted waters.122...

The described method of simultaneously measuring the total absorbed dose by passive dosimetry and biomonitoring shows excellent reproducibility over a range of four states, six worker types, and a range of 84 test replicates (one replicate = one volunteer). 

Collectively, the data from Table 7 and Figures 1 through 3 lead to the conclusion that concurrent biomonitoring and passive dosimetry techniques can be achieved and are not divergent worker exposure assessment methods. The correlation between exposure levels measured by these methods is quite good. 

Assessments of risks associated with the use of chlorpyrifos insecticide products for workers have been made. The assessments are based on the results of field studies conducted in citrus groves, a Christmas tree farm, cauliflower and tomato fields, and greenhouses that utilized both passive dosimetry and biomonitoring techniques to determine exposure. The biomonitoring results likely provide the best estimate of absorbed dose of chlorpyrifos, and these have been compared to the acute and chronic no observed effect levels (NOELs) for chlorpyrifos. Standard margin-of-exposure (MOE) calculations using the geometric mean of the data are performed however, probability (Student s f-test) and distributional (Monte Carlo simulation) analyses are deemed to provide more realistic evaluations of exposure and risk to the exposed population. 

The results from the several studies that have been conducted to measure exposures associated with the use of chlorpyrifos are summarized in Tables 1 and 2. Table 1 summarizes results from mixer-loader and applicator studies reported by Honeycutt et al.1 Listed for each work description are the number of replicates, the arithmetic mean, and the geometric mean for the replicates from both the passive dosimetry measurements and the biomonitoring tech-...
