tailieunhanh - PERSISTENT ORGANIC POLLUTANTS (POPs)

Wastes are very process-specific but the key pollutants can be derived from knowledge of: the process, construction materials, corrosion / erosion mechanisms and maintenance materials. Waste audits are used to gather information on the source, composition, quantity and variability of all wastes. Waste prevention typically involves preventing the arising of waste at source, minimising the arisings and recycling any waste that is generated. The choice of treatment technique is very specific to the process and the type of waste arisings and is often contracted-out to specialised companies. Catalysts are often based on expensive metals and are regenerated. At the end of their life. | TRAINING FOR THE HEALTH SECTOR Date .Place .

NOTE TO USER This is a large set of slides from which the presenter should select the most relevant ones to use in a specific presentation. These slides cover many facets of the problem. Present only those slides that apply most directly to the local situation in the region. POPs LEARNING OBJECTIVES To learn about POPs persistent organic pollutants and related substances To learn why and how POPs may affect children s health To identify gaps in knowledge and research needs To review international agreements and recommendations on POPs To discuss how health care providers and different stakeholders can take action to prevent exposure 2 READ SLIDE. NOTE TO USER Please add other objectives if relevant and refer to the situation of the country concerning the ratification of the Stockholm Convention and national implementation plans NIPs . POPs WHAT ARE POPs Synthetic organic chemicals Persistent in environment Long-range transport leads to global pollution Lipophilic Accumulate in food chain High levels in fish and marine mammals Acute toxicity well characterized 3 The POPs are Synthetic man-made organic chemicals - they are all synthetic chemicals either intentionally or non-intentionally produced released. Some are pesticides others are industrial products or unintended by-products resulting from industrial processes or combustions see next slide . Persistent in the environment - their persistence in the environment is remarkable - it may take them decennia or centuries to be degraded. Long-range transport leads to global pollution - Some POPs will almost always be found if .
