"During the latter part of the 20th century chemical industry grew rapidly, and with
this growth new industrial chemicals found their way into the natural environment.
Pesticides came to be used on a larger scale, and questions were asked about residues
of them that were found in environmental samples (biota, soil, water, and air). Residues
were also found of a range of industrial chemicals in effluents entering rivers and
polluted air. Some of these events received extensive media coverage, which was something
of a mixed blessing. While important discoveries were made known to a wide audience,
inaccuracies and half-truths crept into this reportage, sometimes leaving a rather
confusing impression to interested laypeople. In time, government laboratories, industrial
laboratories, and universities became involved in the investigation of pollution problems,
and the discipline of ecotoxicology began to take shape. Today ecotoxicology courses
are offered by universities and colleges of further education. While a number of textbooks
are now available to students who follow ecotoxicology courses at universities and
other institutions of higher education, there appears to be a shortage of texts aimed
at interested laypeople. This seems unfortunate, because the science underlying environmental
pollution has intriguing aspects to it. There is much evidence for the phenomenon
of chemical warfare in nature, which, over a long period, has been a driving force
in the evolution of plant toxins and the production by animals of systems that detoxify
them. The selective pressure of pesticides has led to the evolution of resistant strains
of pests. The biomagnification of recalcitrant organic pollutants in food chains has
raised problems for predators of higher"
