Oil sludge constitutes the most important type of solid waste in terms of quantity (Linden et al., 1990).

Such franchises may cover local sanitation network extension, sludge removal and disposal, sewage collection and treatment and other service delivery.

It can wash the sludge off high mountain peaks and hills, down into the lowlands. So stop and think for a minute.

The emerging stew of Weltpolitik thickened even more with Israel s pre emptive move in international waters to stop a flotilla supposedly bringing relief aid to blockaded Gaza.

If we look around us, much of what surrounds us started life as various rocks and sludge buried in the ground in various places in the world.

These include biodigester septic tanks for treatment of domestic sewage anaerobic pond systems for treating agricultural processing wastes and anaerobic sludge reactors for the treatment of food processing waste water.

But these haze particles, it was surmised, before we got there with Cassini, over billions and billions of years, gently drifted down to the surface and coated the surface in a thick organic sludge.

While high density urban settlements generally require sewerage networks and waste water treatment facilities, in low density settlements on site sanitation, such as septic tanks with sludge removal, may be an option with significantly lower costs.

Sewage is produced by all human communities and is often left to compost naturally or is treated using processes that separate solid materials by settlement and then convert soluble contaminants into biological sludge and into gases such as carbon dioxide or methane.

For example, animal studies may provide useful information in terms of clinical signs of toxicity (dyspnoea, rhinitis etc) and histopathology (e.g. hyperemia, edema, minimal inflammation, thickened mucous layer) which are reversible and may be reflective of the characteristic clinical symptoms described above. Such animal studies can be used as part of weight of evidence evaluation
