International Pellet Watch: Global monitoring of persistent organic pollutants (POPs) in coastal waters. 1. Initial phase data on PCBs, DDTs, and HCHs

Persistent Organic Pollutants ("POPs")

Strictly speaking, all toxins entering the environment can be regarded as environmental poisons. Certain pollutants can, acting over long periods, harm living organisms even in low concentrations. This means that pollutants that are stable and thus persistent have a great ability to act as environmental poisons. Their stability means not only that their effects are long-lasting, but also that t...

Persistence and Bioaccumulation of Persistent Organic Pollutants (POPs)

Long Term Monitoring of Persistent Organic Pollutants (pops) in Wild and Rope Grown Blue Mussels (mytilius Edulis) from Scottish Coastal Waters

Selected persistent organic pollutants (POPs) in the Italian environment.

The ratification of the Stockholm Convention on Persistent Organic Pollutants is a departure point for several considerations on their presence in environmental matrices. In this paper, the Italian situation is presented with emphasis on the most toxic compounds--chemicals with dioxin-like toxic action, and the activity in the area of interest of the Istituto Superiore di Sanità. Biotic, as wel...

Spheres of influence: no POPS. Persistent organic pollutants.

(ONFLICTING results have beeni reported with neonatal thymectomy in relation to several different chemical carcinogens given to animals by various routes. Some authors (Miller et al., 1963; Grant & Miller, 1965; Nomoto & Takeya, 1969) have shown that tumour induction could be increased in thymectomized animals when they were compared with a group that had had sham thymectomy. When thymectomized...
