-Studies of chemical ecology of an organism are founded on the isolation and identification of a semiochemical, often comprised of two or more synergistic compounds (each synergist alone has little activity, but presented together they are bioactive). Chromatographic fractionation and bioassay methods of binary splitting, additive combination, and subtractive combination are compared for effici...

The consequences of agricultural pesticide exposure continue to be major environmental health problems in rural communities. Community-based participatory research (CBPR) is an important approach to redressing health disparities resulting from environmental causes. In this article we introduce a collection of articles that describe projects using CBPR to address the health disparities resulting...

The effects of methylenedioxyphenyl insecticide synergists on human health arise, not from their intrinsic toxicity which is relatively low, but from their dual effect on the oxidative detoxication or intoxication processes of the body. They are able to inhibit these reactions by two mechanisms. They are substrates for mixed function oxidation and, thus, compete with other xenobiotics for avail...

In this work, a series of intumescent flame retarded polybutylene succinate (PBS) formulations have been developed based on ethylenediamine phosphate (EDAP) and different co-additives, i.e., zinc borate, melamine molybdate, aminated multiwall carbon nanotubes, at relatively low loading (10 wt.%). Among them, borate endows the best synergistic retardant effect with EDAP in PBS. Cone calorimetry ...
