Metropolitan areas are experiencing waste management problems due to the considerable volume of municipal waste generated and the limited space for landfills. Some communities are including incineration as part of their waste management strategy. Incineration is the destruction of materials by the controlled application of heat and is a chemically complex process that leads to the de novo formation of a large number of compounds, many of which have known toxicologic properties. This article explores some of the de novo toxicants formed during incineration of municipal waste and hazardous waste.

Recent research has shown that recreational water and bathing beach quality are associated with injury, infection and personal well-being. Continued surveillance is essential to audit the environmental and associated health trends. In the Coastwatch UK project and since 1989, annual surveys each autumn have been undertaken during a two-week study period, into the extent of littering of the UK coastline. The Public Health Laboratory Service also collects data on the use of hepatitis B immunoglobulin. In these studies it is now possible to examine time trends. The findings are not reassuring. They help to justify present concern about the health effects of discarded litter and medical waste and fears that environmental degradation could lead to loss of income from tourism. In response, some health and local authorities have started public education programmes, supplying litter bins on or near bathing beaches, emptying them regularly and undertaking beach cleansing during the summer months. The UK government is also introducing new legislation that will require 6 mm fine mesh wire screens on all shore-based sewage outlets around the UK coastline. Continued monitoring is needed to assess the effectiveness of these interventions. The need for greater personal responsibility is particularly identified.
