Deltamethrin and piperonyl butoxide two synthetic pyrethroids, when used in a combination it produces synergistic effect. This two insecticide has found to be widely used in the management of mosquito, housefly and other insects to control the various vector born diseases. In this review we assessed the toxic effect of deltamethrin and piperonyl butoxide on beneficial organisms commonly available in the ecosystem. It was found to be toxic to fish, honey bees the prime pollinators of crop plant; earthworm is also susceptible at a lethal concentration for a particular exposure. As far the birds are concerned, they have a less toxic risk in lower concentration of exposure. The alterations obtained in the hematological, biochemical and histopathological studies, further conclude that it can cause environment hazards and toxic to the non-targeted organisms. This investigation gives an insight into the combined toxicological profile of deltamethrin and PBO for better risk assessment and safe use of pyrethroids and their synergist in non-targeted organisms.

AbstractThe effects of benzo(a)pyrene (Bap) (0.03, 0.3 and 3 μg L−1) and chrysene (CHR) (0.3, 2.1 and 14.7 μg L−1) on the function of the immune system of juvenile white shrimp Litopenaeus vannamei were determined under laboratory conditions. This included the total hemocyte count (THC) in the hemolymph, phagocytic activityand pro-phenoloxidase (pro-PO) activity of the hemocyte, phenoloxidase (PO) activity, α2-macroglobulin (α2-M) activity, bacteriolytic activity and antibacterial activity in the hemolymph. The results showed that BaP and CHR could inhibit the immune function of L. vannamei significantly under high concentration BaP and CHR exposure. The results of this study indicated that the immunotoxicity of PAHs in a descending order was BaP>CHR. Moreover, the results indicated the THC in hemolymph, pro-PO activity and phagocytic activity of hemocyte, and bacteriolytic activity in hemolymphcould be used as potentially suitable biomarkersfor early warning indication of PAHs toxicity, this could provide useful information for toxic risk assessment of environmental pollutants.

Toxic Risk

The release of toxins occurs from a multitude of sources both with and without air pollution control. These sources have become of more concern. The value of pollution control for toxicants can be addressed from a risk benefit methodology. The risks can be estimated from the Air Emission Risk Assessment Model (AERAM), a computerized methodology developed by EPRI for the electric utility industry, used to assess cost-benefit trade-offs for various control techologies. This methodology considers particle-size class emissions, dispersion, and health impacts, and has been used to evaluate trade-offs for fuel switching at a coal-fueled electric-power generating station in the Northeastern United States.
