|
| Like concentrations, loadings of banned organochlorine pesticides continue to decline. |
|
| On the positive side, though, Mr Bjordal adds that should regulators decide that organochlorine levels in fish feed are a problem, the industry has the technology to reduce them. |
|
|
|
| Tests were carried out on their blood to search for traces of 15 organochlorine pesticides. |
|
| As we have shown for the section on wastewater, in the solvent washing operation, organochlorine compounds are highly volatile and as a consequence, vaporisation into the atmosphere is produced. |
|
| Endosulfan is an organochlorine pesticide as are DDT, dieldrin, and chlordane. |
|
| Following the banning or great reduction in the use of most organochlorine pesticides, populations have rebounded in virtually every part of the world and now exceed historical levels in many regions. |
|
| The process began around 1956 and was almost certainly caused by the introduction of powerful organochlorine pesticides such as aldrin and dieldrin. |
|
| Some cleaners incorporate industrial solvents and organochlorine compounds into their active ingredients in order to boost their cleaning power on remains of dyes and printing pastes. |
|
| It has been shown that organochlorine pesticides such as DDT can delay the development of hunting behaviour in the young and cause eggshells to thin. |
|
| Although the use of most organochlorine pesticides has been phased out for sometime, they are still detected in the marine environment, due to their extreme persistence, to illegal use or to use elsewhere. |
|
| Various studies indicate that some organochlorine pesticides are detected in various marine species at low levels, which may give rise to concern. |
|
| While the high pollutant levels were not considered the direct cause of mortality, they illustrate the vulnerability, at least of this population, to heavy metal and organochlorine pollution. |
|
| This distance is larger than that of the other organochlorine pesticides that were part of this study including the currently listed POPs dieldrin, DDT and heptachlor. |
|
| It reduces the concentration of many toxic compounds, including numerous medications, pesticides, organochlorine compounds and fixes the heavy metal ions. |
|
| Although organochlorine chemical contamination has been a past concern for the state of health of the harbour porpoise, concentrations appear to have diminished in recent years. |
|
| Pesticide biomagnification caused organochlorine to build up in the falcons' fat tissues, reducing the amount of calcium in their eggshells. |
|
| Chemical analyses showed that the Baltic fish carried 10 times as much toxic organochlorine contamination as did the North Atlantic herring. |
|
