Chemical industry's bad reputation
"The recent debate over oestrogenic chemicals in the environment has placed the reputation of the chemical industry at stake," according to Simon de Bree, president of the European Chemical Industry Council (CEFIC) at a recent meeting. Results of CEFIC's 1996 public opinion survey indicate generally that the European public thinks less of the chemical industry compared with opinions two years ago. The public also believe industry is making less effort to control pollution. People do not think chemical companies are fair and open with information, except in Belgium. With a sense of foreboding, de Bree concluded: "It is dangerous to have this lowly image; only the nuclear industry has a worse one."

Worry over Salmonella-based rodenticides
Public health scientists in the US have learnt that commercially available Salmonella-based rodenticides are being produced in Cuba and distributed to developing countries world-wide. The information on the package states that the product, salmocoumarin (Biorat), is innocuous to humans and does not contaminate the environment.
    The use of Salmonella as a rodenticide was proposed a century ago. The agents were found to have no definable impact on rodent populations and caused illness and death in humans during their preparation and handling. A trial of Salmonella among farm rats showed that some rats remained culture positive for at least one year, during which the rat population doubled in size. Salmonella-based rodenticides were banned in the US, Germany and the UK in the 1920s, 1930s and 1960s respectively.

DDT masquerading as 'pyrethrum'
The Lion brand of mosquito coil, manufactured in China, used to be imported into Jamaica. It had a label stating it contained pyrethrum powder 1.3%. In 1995, during a random assessment of the product for quality control, the coils were found to contain between 6-8% DDT. This result was confirmed by three separate laboratories both in Jamaica and in the US. All three laboratories found no trace of pyrethrum in the samples tested. DDT is banned in Jamaica but, even so, this constitutes an obvious case of fraud. The product has since been removed from the shelves and, according to the Jamaican Pesticides Control Authority, no further importation will be allowed into the country.

DDT poisons Italian lake
Lake Maggiore in Italy has been found to contain at least six times the permitted level of DDT. Levels of this insecticide, widely banned across Europe, have been discovered in some fish caught in the Lombardy lake. Edo Ronchi, Italy's environment minister, blamed industry for dumping DDT.
