UNLABELLED Many environmental compounds with oestrogenic activity are measurable in the human breast and oestrogen is a known factor in breast cancer development. Exposure to environmental oestrogens occurs through diet, household products and cosmetics, but concentrations of single compounds in breast tissue are generally lower than needed for assayable oestrogenic responses. Results presented...

Chemical products are present in most households and can endanger the health of humans, particularly toddlers pre-school children. With a focus on accident prevention, this article investigates parents other caretakers’ beliefs perspectives risks responsibilities. A mixed method approach was applied, combining in-depth qualitative interviews (pre-study, N = 10) quantitative survey (main study, ...

Current chemicals regulation operates almost exclusively on a chemical-by-chemical basis, however there is concern that this approach may not be sufficiently protective if two or more chemicals have the same toxic effect. Humans are indisputably exposed to more than one chemical at a time, for example to the multiple chemicals found in food, air and drinking water, and in household and consumer...

Since World War II, approximately 80,000 new commercial synthetic chemicals have been released into the environment, with approximately 1500 new chemicals released annually. Most of these have not been adequately tested for their impacts on human health or their particular impacts on children and the developing fetus. Yet, children are exposed to hazardous chemicals through residues in their fo...

BACKGROUND Household cleaning and pesticide products may contribute to breast cancer because many contain endocrine disrupting chemicals or mammary gland carcinogens. This population-based case-control study investigated whether use of household cleaners and pesticides increases breast cancer risk. METHODS Participants were 787 Cape Cod, Massachusetts, women diagnosed with breast cancer betwe...

Most compounds considered toxic to mammals should also be considered toxic to birds. Table 37.1 offers a guide for treatment of intoxication from some common household products. Based on their size and physiology, birds are more prone than mammals to intoxication by some compounds, such as volatile chemicals and fumes. Psittaciformes have a propensity to chew on almost anything. All avian clien...
