Hazardous substance management

Chemical elements, compounds, classes and physical state 

A basic knowledge of hazardous substanees will help you to understand the way they look and behave, making the names more meaningful. 

Nature of atoms and molecules, elements and compounds Atoms 

Atoms have a nucleus (centre) surrounded by a cloud of electrons (negatively ehaiged particles) in orbit around the nucleus. The word electron comes from the Greek word for amber, because electricity was first discovered by mbbing amber (fossilized tree gum). 

Chemicals consist of atoms. The word atom means something that eannot be cut. An atom is the smallest particle of a chemical element whieh still has the ehemical properties or chemieal behaviour of that element. Cut the atom further and it is no longer the same chemical element.

The regulatory standards for leak detection in tank systems containing hazardous chemicals are more stringent than those for tanks containing petroleum motor fuels. Both above standards and those required in RCRA hazardous substances management should be met. 

The plant manager of an industrial site having hazardous substances must establish an in-plant hazardous substance management program to ensure that the plant s hazardous substances will not be released by accident, or by neglect, to the plant s soil and groundwater.

Various Approaches in Chemicals and Hazardous Substances Management for Asia and Europe... 

The Asia-Europe Environment Forum (ENVforum) sets forth on its second phase of development by organising the 4th Roundtable Combine or Combust Cooperating on Chemicals and Hazardous Substances Management . This roundtable was held in Brussels, Belgium, from 28-30 November 2006. Following up on the rich discussions held, selected proceedings and papers have been compiled in this volume. 

It is imperative that common global approaches are adopted in chemicals and hazardous substances management. While in the past, the approach has been more specific issue-based with clearly outlined boundary conditions (e.g., Montreal Protocol on Ozone Depletion, Stockholm Convention on Persistent Organic Pollutants), the current approach entails a globalised strategic integrated view.
