Determination of traces of organic compounds has become especially important, as many of those species have been introduced into the environment in an uncontrolled way. Sometimes those substances were used because of their special positive activity, but harmful effects became obvious later. A known example is the insecticide DDT (dichlorodiphenyltrichloroethane), which does not decompose rapidly in nature but accumulates dangerously in many organisms. Among other active species formed in many industrial processes are polycychc hydrocarbons and dioxins (chlorinated derivatives of dibenzodioxins), both highly toxic species that are now present in nearly all environmental media. Determination of individual species is difficult because they are accompanied by numerous compounds of similar stmcture (congeners, isomers, homologs) and closely related chemical properties. 

The next step is the application of the microcantilever as biosensor in the environmental control field, by following an immunological detection scheme. For this purpose, we present the inhibition immunoassay performed to detect the highly toxic organochlorine insecticide compound dichlorodiphenyltrichloroethane (DDT). 

As with all chemicals, the dose makes the poison. The chlorine-containing insecticide dichlorodiphenyltrichloroethane (DDT) is highly effective in killing disease-ridden mosquitoes, ticks, and fleas, but it is virtually nontoxic to mammals. The fluorine-containing pesticide 1080, or fluoroacetic add (FCH2CO2H), is highly toxic and often lethal to all mammals. The industrial and combustion by-product dioxin is highly toxic to some animals but not to others in humans, dioxin causes the skin disease chloracne. 

DDT (dichlorodiphenyltrichloroethane) was developed in the late 1930s and became one of the first insecticides to be used around the globe. It was found to exhibit strong toxicity for insects but rather low toxicity for mammals. DDT was used as an insecticide for many decades and has been credited with saving more than half a billion lives by killing mosquitos that carry deadly diseases. Unfortunately, it was found that DDT does not degrade quickly and persists... 

As microplastics move through the environment they can sorb and transport other contaminants. Plastic debris scooped from the ocean has contained polychlorinated biphenyls (PCBs) at concentrations up to 5 parts per million and dichlorodiphenyltrichloroethane (DDT) at approximately 7 PPM, for example [145-147]. Of particular concern are persistent, bioac-cumulative, and toxic (PBT) compounds that would tend to partition into a plastic matrix due to their hydrophobicity the logical inference is fhaf floaf-ing microplastics could transport PBT compounds through the environment and that perhaps the PBT compounds would enter the food chain as organisms ingested fhe plastic fragments.
