Organic associations

A considerable number of mycotoxins that show high toxicity to vertebrates and/ or invertebrates are produced by organisms associated with crop plants (Flannigan 1991). There are many known cases of human poisoning caused by such compounds. There are three broad categories of mycotoxins represented here, based on the structures of the intermediates from which these secondary metabolites are derived. They are (1) compounds derived from polyketides, (2) terpenes derived from mevalonic acid, and (3) cyclic peptides and derivatives thereof.

Some sort of compromise needs to be reached. The buyer and the consumer must have the guarantee that what is called organic really is. So either the organic associations such as the Soil Association have to reduce their charges or, conceivably, the government may be asked to make a grant to cover this aspect.

Bates et al. [35] collected suspended particulate matter from river water and wastewater effluents using high speed continuous flow centrifugation, and analysed the isolated solids for hydrocarbons. The results were compared with those obtained on samples obtained by glass filter filtration. It was concluded that the use of a continuance flow centrifuge allows the concentration of organic associated with suspended particulate matter to be estimated more accurately. 

Deaths of target organisms associated with intentional pesticide applications to insect-infested crops, weed-choked roadsides, and nematode-laced fields are predictable, desirable, and relatively easy to measure. Likewise, catastropic releases of chlorine from ruptured tank cars or of crude oil from scuttled supertankers may produce a spectrum of biological effects including toxicity. These events are easily associated with exposures to toxic substances and particular environmental circumstances. 

Toxic pollutants resulting from production processes within this industry are generally the result of leaks, spills, and poor housekeeping procedures. Pollutants include organics associated with the raw materials and lead from the rubber curing process. 

Richardson also devised many novel reagents and chromogenic substances that are now used in various diagnostic kits of value for the rapid and accurate visual detection of human disease, as well as for the identification of pathogenic organisms associated with disease. For chemical posterity, it is therefore considered important to present a detailed account of Richardson s numerous research contributions. 

Enhanced levels of chlorinated compounds have been observed indoors due to human activity as well. For example, increased levels of perchloroethylene have been observed from unvented dry-cleaning units (e.g., Moschandreas and O Dea, 1995) and volatilization of chlorinated organics such as chloroform from treated tap water can occur (e.g., McKone, 1987). Other sources include the use of household products. For example, chloroform emissions have been observed from washing machines when bleach containing hypochlorite was used (Shepherd et al., 1996). It is interesting that emissions of organics associated with the use of washing machines are decreased when the machine is operated with clothes inside (Howard and Corsi, 1998).
